WHY IC PARTS
Built for procurement engineers.
01 / SPECIALTY
Obsolete & Hard-to-Find
Decades of experience sourcing parts that other distributors no longer carry — EOL ICs, last-time-buy stock, and parts in active production allocation.
02 / SPEED
Fast Quote Turnaround
A real sourcing engineer reviews every RFQ and most responses go out same business day — not a templated reply, a real quote with provenance.
03 / QUALITY
Verified Supplier Network
Every part is sourced through vetted channels with documented chain-of-custody. Test reports and date codes available on request.
04 / IDENTITY
US-Based, US-Operated
Headquartered in New Jersey with a US-based sourcing team. No outsourced reps, no offshore handoffs — just a phone number that goes to a person who knows ICs.
