Board-to-Board Header for Standard Grid Layouts
The Amphenol FCI 87900-122HLF is a 22-position (2×11) unshrouded male header from the BERGSTIK® II series, built on the standard 0.100" (2.54 mm) pitch grid. It's a through-hole solder-terminated part with a push-pull fastening interface, designed for board-to-board stacking or wire-to-board connections when mated with the matching receptacle. The 0.100" pitch matches the most common prototyping and perfboard grid, so this header slots into existing layouts without a custom footprint.
What the Key Ratings Mean for Your Build
Rated 5 A per contact at 110 V, this header handles signal-level loads and low-power DC rails comfortably — think logic-level interfaces, sensor inputs, or parallel data lines. The 30.0 µ" gold or Gold GXT™ plating on the mating surface gives it a solid corrosion barrier and supports moderate mating cycles, so it's fine for field-serviceable connections where the board gets plugged and unplugged a few dozen times over its life. The 0.100" row spacing matches the same pitch, keeping the pin field uniform for routing.
Sourcing and Lifecycle
This part is active — still in regular production with no end-of-life notice. No official cross-reference or direct equivalent is listed, so match the 22-position count and 0.100" pitch against your BOM before committing.
