The Amphenol ICC (FCI) 87900-104HLF is the 4-position member of the BERGSTIK II dual-row header series — a 0.100" (2.54mm) pitch, board-to-board male pin header intended for through-hole soldering onto a PCB. With 4 loaded circuits, a 5 A per-contact current rating, and a 110 V rating, it serves as a compact signal or low-power interconnect in industrial automation, instrumentation, and legacy communications equipment where the 2.54mm dual-row footprint has an established design presence.
Contact plating and what the 30 µin gold means for this application
The contact material is phosphor bronze, which provides good spring properties and conductivity at the termination interface. The square pin cross-section gives consistent wipe geometry across multiple insertions.
