What this connector is
The Amphenol FCI 87900-410HLF is a dual-row 10-position unshrouded male pin header in the BERGSTIK II series, designed for board-to-board stacking at 0.100-inch (2.54 mm) pitch. Through-hole solder termination and a push-pull mating interface make it suited for permanent or semi-permanent board-level interconnects where the z-height budget allows a through-hole profile. The housing is rated UL94 V-0, confirming the base material meets a recognised flammability standard.
Key ratings for the selection decision
Where these headers are typically used
Board-to-board headers in the 0.1-inch pitch class appear across industrial control cards, instrumentation front panels, and embedded-comms modules — anywhere a reliable, repeatable through-hole footprint anchors a daughter card to a backplane or mid-plane. The BERGSTIK II family's dual-row configuration and square pin shape provide good registration during mating, and the unshrouded design keeps the footprint compact when multiple headers share a board edge.
