Hybrid Electronics carries 6.7 million+ units across 1,282 unique STMicroelectronics part numbers — from current-production STM32 microcontrollers to obsolete M27 EPROMs and HCF logic no one else has on the shelf. Same-day quotes, traceable stock, and OEM-excess pricing on ST components since 1995.
STMicroelectronics — often written as ST, STMicro, or STM — is a Franco-Italian semiconductor manufacturer headquartered in Geneva and one of the ten largest chipmakers in the world. Formed in 1987 from the merger of SGS Microelettronica and Thomson Semiconducteurs, the company today serves automotive, industrial, personal electronics, and communications customers from wafer fabs in Crolles (France), Agrate Brianza (Italy), Catania (Italy), and Singapore.
Hybrid Electronics has been sourcing ST components since 1995. Our line card covers both current-production ST parts and — importantly for defense, medical, and legacy industrial buyers — the obsolete and last-time-buy inventory that ST’s authorized distributors no longer stock.
STM32 series (F0, F1, F2, F3, F4, F7, G0, G4, H7, L0, L4, L5, U5, WB, WL), plus ST7, ST10, STM8, STLUX, and legacy 8-bit ST6/ST7. Full ecosystem support with programmed and blank parts.
STP, STB, STD, STW, STF, STL, STGB, STGP power packages — including obsolete part numbers still in demand for medical, avionics, and industrial replacement. Deep inventory in STripFET and STPOWER product lines.
L78/L79 fixed and adjustable regulators, LD1117 and LD29 LDO families, ST1S switch-mode DC/DC, and TS-series references. Complete cross-referencing to Motorola, Fairchild, and NSC obsolete equivalents.
M27 EPROM (M27C64, M27C256, M27C512, M27C1001, M27C2001, M27C4001), M28 NVRAM and Timekeeper (M28C64, M48T02), M29 Flash (M29W, M29F, M29DW families), and M35 serial EEPROM. Full DIP, PLCC, TSOP, and BGA package coverage.
HCF4000-series CMOS logic (HCF4001, HCF4013, HCF4017, HCF4046, HCF4066, HCF4093), M74HC and M74HCT high-speed CMOS, and legacy M74LS TTL. Over 500 unique ST-brand logic devices on the shelf.
TS-series (TS274, TS391, TS431, TS482, TS555, TS920, TS944, TS951, TS971, TS27M) and precision comparators. RS-232/RS-485 transceivers, level shifters, and USB interface chips.

A large fraction of the STMicroelectronics inventory that end-of-life notices (PCN/EOL) push out of the authorized channel each year still lands in one of three places: OEM excess, distributor de-stock, and factory close-outs. We buy from all three. Common ST families we’re asked to source obsolete:
