MIL-PRF-19500 manufacturer profile

VPT Components — JAN, JANTX, JANTXV, JANS & JANSR discrete semiconductor manufacturer

VPT Components is a Massachusetts-based, JANS-certified manufacturer of high-reliability discrete semiconductors qualified to MIL-PRF-19500. Formed in 2019 as a collaboration between VPT, Inc. (a HEICO company) and the long-established SST Components, Inc. — and expanded through the September 2018 acquisition of MACOM's Hi-Rel Components business (formerly Aeroflex Metelics) — VPT Components today runs two DLA-certified plants and is one of the largest JAN-certified diode and transistor suppliers on the DLA QPL. Hybrid Electronics sources VPT Components MIL-PRF-19500 parts for defense, aerospace, and space program buyers on a sourcing-only basis.

VPT Components vs VPT, Inc. — the naming buyers need to get right

The single most common sourcing mistake on this brand is confusing VPT Components with VPT, Inc. Both are part of the HEICO Electronic Technologies Group, but they are separate operating businesses with entirely different product lines, specifications, and websites — and a MIL-PRF-19500 part number cannot be sourced from the DC-DC converter arm.

  • VPT, Inc. — headquartered in Blacksburg, Virginia (vptpower.com). Designs and manufactures MIL-PRF-38534 Class H and Class K DC-DC converters, EMI filters, and point-of-load modules for avionics, military, and space power systems. This is a hybrid-microcircuit manufacturer, not a discrete-semiconductor house.
  • VPT Components — headquartered in Lawrence, Massachusetts (vptcomponents.com). Manufactures MIL-PRF-19500 discrete semiconductors — diodes, bipolar transistors, rad-hard MOSFETs, Schottky rectifiers, zeners, and SCRs — at JAN, JANTX, JANTXV, JANS, and JANSR quality levels. This is the business appearing on the DLA QML-19500 list under the entries "VPT Components (Billerica)" and "VPT Components (Lawrence)".

VPT Components should also not be confused with Compensated Devices, Inc. (CDI) — a separate Massachusetts JAN house acquired by Microsemi in 2001 and now part of Microchip Technology's Microsemi Lawrence QML entry. That is a distinct manufacturer with a distinct CAGE code and a distinct QPL history.

About VPT Components

VPT Components was announced on March 6, 2019 as a collaboration between VPT, Inc. and SST Components, Inc., a long-established MIL-PRF-19500 JANS-certified semiconductor manufacturer whose home plant was in Billerica, Massachusetts. On launch, the combined operation was publicly described as the second-largest provider of JAN-certified semiconductors in the world, ranked by the number of parts listed on the Defense Logistics Agency Qualified Products List.

The other side of that combined footprint was already in place. In September 2018, VPT Components had acquired the assets of MACOM's Hi-Rel Components business in Lawrence, Massachusetts — the former Aeroflex Metelics Hi-Rel operation. That transaction brought a substantial MIL-PRF-19500 slash-sheet portfolio, a fully-equipped high-reliability manufacturing line, and a QML entry that VPT Components committed to maintain and grow. Since 2018, the combined business has added thousands of new part numbers to the DLA QPL/QML across both facilities.

In 2021, VPT Components consolidated primary operations into the Lawrence headquarters, invested over $10 million in new manufacturing equipment and product development, and expanded clean-room capacity for custom discrete and hybrid assembly of hermetically sealed components. Both the Lawrence and Billerica sites remain separately listed on the DLA's real-time QML-19500 company list, giving VPT Components two distinct QML entries and two distinct CAGE codes — a structure that program-office source-approval documents and DLA contract awards typically treat as two independently qualified sources.

Corporate structure sits under HEICO. VPT, Inc. is part of the HEICO Electronic Technologies Group, itself part of HEICO Corporation (NYSE: HEI / HEI.A) — a diversified aerospace and defense group. VPT Components inherits that financial backing and long-horizon investment posture, which is why the business has been able to fund a full facility refurbishment, run a $10M-plus capex program, and continually add slash-sheet qualifications since 2019.

What Hybrid Electronics sources from VPT Components

Hybrid Electronics is an independent stocking distributor and sourcing agent. We are not authorized by VPT Components. What we do is fill the gaps that franchise distribution can't always fill: obsolete slash-sheet variants, allocated JANS material, single-lot quantities for pilot builds, and end-of-program pulls where a program office needs specific date codes and traceability. Across VPT Components, the families we source most often are:

  • Silicon switching and rectifier diodes — JAN, JANTX, JANTXV, and JANS variants of the classic 1Nxxxx families qualified across many MIL-PRF-19500 slash sheets.
  • Zener diodes — including small-signal reference zeners and higher-power axial zeners at JAN through JANS levels.
  • Schottky barrier rectifiers — including surface-mount UR-suffix packages qualified to MIL-PRF-19500/586.
  • Bipolar transistors — small-signal and power switching NPN and PNP families in TO-18, TO-46, TO-39, TO-3, and surface-mount U / UA / UB packages. JAN through JANSR where the underlying slash sheet supports it.
  • Radiation-hardened MOSFETs — VPT Components' rad-hard MOSFET line covers JAN through JANSR levels, 100 krad(Si) total dose, across MIL-PRF-19500 slash sheets. VPT Components' Lawrence plant is also the named DLA-VQE contracted assembly site for Renesas' JANS rad-hard power MOSFET wafer program.
  • Silicon Controlled Rectifiers (SCRs) — power SCRs qualified to MIL-PRF-19500 for high-reliability switching and power-conditioning applications.
  • JANHC and JANKC qualified die — bare die for buyers building custom hybrids qualified to MIL-PRF-38534.

QPL history and current DLA status

VPT Components' MIL-PRF-19500 lineage runs through two long-standing QPL houses. The Billerica operation traces its qualification history to SST Components, a JANS-certified independent whose QPL entries pre-date the 2019 combination. The Lawrence operation inherited the QPL entries of the former Aeroflex Metelics / MACOM Hi-Rel line at the moment of the September 2018 asset acquisition, and VPT Components explicitly committed to maintaining and expanding those slash-sheet qualifications.

On the current DLA Land and Maritime real-time QML-19500 company list, VPT Components appears as two separately qualified sources:

  • VPT Components (Lawrence) — CAGE code 52GC4, 9 Hampshire Street, Lawrence, MA 01840. The 50,000-square-foot headquarters plant, with 12,000-plus square feet of cleanroom, DLA-VQE laboratory suitability status for MIL-STD-750 and MIL-STD-883, and over 107 on-site test methods.
  • VPT Components (Billerica) — CAGE code 9N185, 780 Boston Road, Billerica, MA 01821. The original SST Components home, 10,000 square feet with a 4,500-square-foot class-10,000 cleanroom for discrete and hybrid assembly of hermetically sealed devices.

Notable slash-sheet activity since the 2019 launch — the parts that most often come up on program-office source-approval documents and that Hybrid Electronics is asked to quote against — includes:

  • November 2018 — high-power NPN transistor families qualified to MIL-PRF-19500 slash sheets /439, /488, /509, /514, and /528 in the TO-3 metal-can package at JAN / JANTX / JANTXV.
  • January 2020 — VPT Components' PNP switching-transistor families under MIL-PRF-19500/290 (industry-standard PNP switching transistor device types) upgraded from JAN / JANTX / JANTXV to the full JANS and JANSR quality levels — a significant addition for space-program buyers who had previously had to substitute or dual-source.
  • April 2020 — NPN high-speed switching transistors qualified at JANS and JANSR across TO-18, TO-46, and surface-mount U / UA / UB package variants.
  • September 2020 — Schottky barrier rectifier families qualified under MIL-PRF-19500/586, adding to VPT Components' surface-mount Schottky offering.
  • June 2021 — additional PNP power transistor device types added under MIL-PRF-19500/508 in the TO-3 package.

MIL-PRF-19500 quality levels VPT Components produces

MIL-PRF-19500 defines a ladder of screening and lot-acceptance test regimes for hermetically-sealed discrete semiconductors. VPT Components is qualified to produce parts across the full ladder — the difference between JAN and JANSR for the same underlying die is not a specification change but a testing and traceability change, and the higher levels carry meaningfully longer lead times and higher unit prices for that reason:

  • JAN — baseline Joint Army-Navy qualification. The underlying qualified device.
  • JANTX — JAN plus 168-hour burn-in and additional 100% screening.
  • JANTXV — JANTX plus 100% pre-cap visual inspection.
  • JANS — space-level qualification with 100% additional screening, wafer-lot acceptance testing, and tightened Group A / B / C / D conformance. This is the level most military-satellite and NASA program offices baseline for hermetic discretes.
  • JANSR — enhanced JANS with radiation lot acceptance testing (RLAT). VPT Components' rad-hard MOSFET line, for example, is characterized to 100 krad(Si) at the JANSR level.
  • JANHC / JANKC — chip-level (bare die) qualifications used by hybrid microcircuit manufacturers building to MIL-PRF-38534.

All qualification and screening is administered by the U.S. Defense Logistics Agency (DLA) Land and Maritime, Columbus, Ohio (VQE Center — formerly DSCC-VQ). DLA-VQE conducts the periodic manufacturer certification audits, controls the QML-19500 listing, and maintains the Qualified Products Database that program offices reference for source approval.

How Hybrid Electronics sources VPT Components MIL-PRF-19500 parts

Hybrid Electronics has sourced electronic components since 1981. On the MIL-PRF-19500 side, most of our work sits in the space that franchise distribution — even a well-stocked distributor like TTI — can't fully cover: obsolete slash-sheet variants, allocated JANS material, small-lot pilot quantities, exact-date-code pulls for depot-level repair programs, and end-of-program excess. That work is very different from mainstream commercial distribution:

Obsolete and hard-to-find JAN parts

Legacy 1Nxxxx and 2Nxxxx JAN part numbers no longer stocked in the franchise channel, older slash-sheet revisions still required by depot-level programs, and long-tail devices that block a defense BOM from closing. We locate stock from a global network of stocking sources and hold parts for scheduled draw-down where a program requires it.

Allocated and long-lead JANS / JANSR material

Space-level JANS and JANSR parts routinely carry lead times measured in many months. Where a program cannot wait for the next lot from the OEM, we work against your source-approval list to find qualified material already in the supply chain, with full traceability, so a build can close on schedule.

Exact date-code and lot-code pulls

Depot-level repair and legacy avionics programs frequently require specific date codes, lot codes, or DPA-tested material. We work from written date-code requirements and can hold parts for pre-shipment inspection where a program's source-inspection clause requires it.

End-of-program excess and consignment

If your program is winding down and you are holding VPT Components JAN or JANS inventory that will not be consumed, we buy excess and hold consignment inventory. Contact us for a valuation.

Cross-references and related DLA programs

VPT Components' MIL-PRF-19500 discrete devices frequently appear on the same BOM as parts qualified under related DLA programs. The three most common cross-referenced specifications are:

  • MIL-PRF-38534 — Hybrid Microcircuits, General Specification. Class H and Class K hybrids frequently consume VPT Components' JANHC / JANKC bare die as building blocks. Note that VPT, Inc.'s DC-DC converters are qualified under this specification (Class H / Class K), which is a common source of confusion with VPT Components.
  • MIL-PRF-38535 — Integrated Circuits, Manufacturing, General Specification (QML). VPT Components' facility is qualified to 38535 standards for custom assembly and screening operations, and the Lawrence lab holds MIL-STD-883 method suitability.
  • DSCC / DLA Land and Maritime drawings — many program-specific Source Control Drawings (SCDs) and DSCC drawings call out VPT Components CAGE codes (52GC4 or 9N185) as approved sources against specific MIL-PRF-19500 slash sheets. If your SCD names a VPT Components part, send us the drawing number and revision along with the RFQ.

Sourcing only. Hybrid Electronics does not offer semiconductor repair, re-screening, or up-screening services, and does not sell counterfeit parts. All quotations are subject to availability, inspection, and traceability review prior to shipment.

Frequently asked questions

Is VPT Components the same as VPT Inc.?

No. Both are part of the HEICO Electronic Technologies Group, but they are separate operating companies with distinct product lines. VPT, Inc.
