10-Position Unshrouded Header for Board-to-Board Interconnects
The FCI 87185-410HLF is a 10-position, single-row unshrouded male pin header from the BERGSTIK® II series. It uses a 0.100" (2.54mm) pitch on the mating interface, matching the standard grid for IDC ribbon cable connectors and many board-to-board receptacles. The header is through-hole mounted with square pins, tin-plated on both the mating surface and the solder tail, and carries a 5A per-contact current rating at the stated voltage limit of 110V.
Key Specs and What They Mean for Your Fit
The 10-position count is the first thing to match against your BOM line — this header populates all positions. The 0.100" pitch is the de facto standard for 2.54mm-grid prototyping and production boards; it gives enough room for one trace between pads on a single-layer board. The 5A per-contact rating is typical for signal-level duty — the limiting factor is the tin plating, which handles moderate mating cycles (tens to low hundreds) but will wear faster than gold under frequent reconnection. The unshrouded design means there is no plastic shroud to guide the mating connector, so the board layout must provide mechanical alignment if the header mates with a cable assembly.
Mating and Termination
This header mates with standard 0.100" pitch IDC socket connectors, such as those in the BERGSTIK II receptacle family. The push-pull fastening type means no locking latch — the connection relies on the friction of the pin-socket interface. The through-hole solder termination suits wave-solder assembly; the 0.095" (2.41mm) post length fits standard PCB thicknesses. The UL94 V-0 rated black housing handles the flame resistance requirement for equipment inside an enclosure.
