Semiconductors are where counterfeit risk is highest and documentation matters most. Whether the request is an NXP RF power LDMOS transistor like MRFE6VP61K25H, a TI 16-channel analog multiplexer such as the CD74HC4067, an LED display driver like LPD6803, or a metal-oxide varistor in the 10D431 class, the sourcing discipline is identical.
How we keep grey-market parts out of your BOM
- Datasheet-verified matching. Every candidate is checked against the original datasheet – package, pinout, electrical limits – not just a number match on a marketplace listing.
- Traceability. Date code and lot consistency are verified with photos before shipment. Re-marked or sanded parts are refused.
- Condition honesty. Factory-new, OEM excess, and tested surplus are quoted separately, never blended.
- Network hardware too. References like the Cisco Catalyst
C9200-48P-4G-Eswitch are sourced with license and PoE budget implications explained up front.
Common pitfalls we screen for
Mixed date-code bins sold as one lot, “equivalent” RF transistors with different thermal pads, battery packs (such as 2S1P configurations) built from mismatched cells, and varistors with shifted clamping voltages. Each of these passes a casual visual check and fails in the field.
