How to read this list
Active parts, connectors and electromechanical parts carry real manufacturer part numbers, each verified against the manufacturer's own datasheet when it was designed in. Qualification is quoted from those datasheets.
Passives are specified parametrically — value, package and the AEC-Q200 requirement — rather than pinned to one vendor. That is how passives are actually bought: an 0603 100 nF X7R AEC-Q200 capacitor is a commodity chosen on value, size, voltage and qualification.
Pricing and stock are not included.Nothing here was checked against a distributor's live catalogue, and availability moves. Two lines are worth confirming first: the Bosch CJ125, long-lived but not a mainline catalogue part, and the eight FGP3040G2 ignition IGBTs — the largest single line.
