We are not a catalog distributor. We source, validate, and deliver the components that keep your production lines running.
Automotive program lifetimes demand cost certainty. ADD locks quarterly fixed pricing on your recurring ECU BOM lines — STM32 MCUs, Infineon MOSFETs, NXP transceivers. HK safety stock, weekly pull, price locked for 12–24 month windows. PPAP documentation maintained per batch — no requalification surprises.
ECU BOMs span MCUs, power discretes, CAN/LIN transceivers, gate drivers, sensors, and connectors across 8–15 brands. ADD consolidates STMicroelectronics + Infineon + NXP + TI + TE into one PO, one PPAP package, one DDP shipment. One supplier relationship for your entire ECU electronics stack.
Automotive programs run 7–15 years — MCU EOL is not an option mid-SOP. ADD monitors STM32, NXP S32K, Infineon AURIX, and Renesas RH850 product lifecycle notices and alerts you 12–24 months ahead. We coordinate lifetime buys and identify drop-in replacements before the PCN hits and your production schedule is at risk.
When STM32 or NXP automotive MCUs are on severe allocation, we cross-reference AEC-Q100 qualified alternates across Renesas RH850, Infineon AURIX, Microchip, TI Hercules. Pin-compatible or functionally equivalent — our FAEs provide cross-reference tables with peripheral mapping so your software team can assess impact in hours, not weeks.
STM32 automotive MCUs, Infineon AURIX TC3xx/TC4xx processors, NXP S32K MCUs, and TI automotive PMICs are our highest-turn automotive lines. HK buffer stock across 1,500+ automotive-grade part numbers. When factory lead times hit 40–52 weeks, our parallel inventory keeps your ECU line running.
AEC-Q100/Q101/Q200 qualified semiconductor supply chain for Tier-1 automotive programs. STMicroelectronics (STM32, SPC5 MCUs), NXP (S32K, i.MX, MPC5xxx), Infineon (AURIX, OptiMOS, CoolMOS), Renesas (RH850, R-Car), TI (automotive PMICs, FPD-Link). Source-disclosed on every line item with PPAP documentation.

Automotive-grade MCUs are on severe allocation. Tier-1 suppliers face production line stoppages waiting for 32-bit MCU deliveries.
Multi-source AEC-Q100 MCU alternatives, 2-week delivery
Sealed connectors and high-speed FAKRA/HSD interconnects face extended factory lead times, delaying harness production.
Global connector sourcing network, 10-day ship
Sourcing from unauthorized channels means missing Production Part Approval Process documentation - a non-starter for automotive quality systems.
Full PPAP Level 3 documentation with every order
When your only qualified MOSFET supplier goes on allocation, your entire power stage is at risk with no fallback.
Cross-reference AEC-Q101 alternates with matching footprints
AEC-Q100 qualified: STM32, SPC5, RH850 - 32-bit ARM Cortex-M/R for body, chassis, and gateway.
AEC-Q100 PMICs, DC-DC converters, gate drivers - power supply for ADAS, infotainment, and body.
AEC-Q101 MOSFETs, IGBTs, SiC, and diodes - from 40V body electronics to 1200V traction inverters.
Automotive-grade connectors, MLCCs, resistors - sealed, high-speed, and high-temperature rated.
An EV Tier-1 supplier building on-board chargers needed SiC MOSFETs, isolated gate drivers, current sensors, and AEC-Q200 MLCCs - fragmented across 12 different vendors with lead times from 4 to 26 weeks.
ADD consolidated the entire BOM, sourcing SiC discretes from multiple authorized channels and holding buffer stock at our Hong Kong warehouse. We delivered synchronized weekly batches against production schedules. 18% cost reduction through consolidated procurement. Zero line stoppages.
