Single-contact spring-loaded pogo pin for board-level interconnect
The Z02J-4F7L1-11000 is a compression contact — a spring-loaded pogo pin, non-gendered, meaning it mates with a flat pad or another spring contact without a dedicated receptacle. One circuit, single row, surface mount on Tape & Reel for automated pick-and-place. Gold flash plating on the contact face — minimal thickness, suited for low-cycle or test-fixture duty where the contact is compressed and released a few hundred times, not thousands. The copper alloy body carries the signal and provides the spring force.
Gold flash vs 8.00 µin gold — plating thickness matters for cycle life
The Z02J carries gold flash — the thinnest gold layer in the family. That extra thickness buys you more mating cycles before the gold wears through to the base metal. For a test-point or battery contact that sees occasional compression, flash is fine. For a connector cycled daily, step up to the 8.00 µin sibling. The Z02E-4F7L1-11000 is a functional equivalent — same package, material, mounting, and gold flash finish. If you need a second source or alternate MPN, that one matches the Z02J spec-for-spec.
