Board-to-Board Header, 25 Positions, 0.100" Pitch
The Amphenol FCI 75160-118-25LF is a 25-position, single-row, unshrouded male pin header from the BERGSTIK series. It is a board-to-board interconnect with a 0.100" (2.54 mm) pitch, through-hole solder termination, and a push-pull fastening type. The contacts are square male pins made of phosphor bronze, with a gold GXT finish on the mating surface at 30.0 µin (0.76 µm) thickness. Rated for 5 A per circuit at 110 V, this header suits signal-level and moderate power distribution on a PCB. The UL94 V-0 thermoplastic insulation and -65°C to 130°C operating range make it a fit for industrial and telecom equipment inside an enclosure.
What the Ratings Mean for Your Fit
The 0.100" (2.54 mm) pitch is the standard 0.100-inch grid — it matches a wide range of perf-board, prototyping grids, and legacy PCB layouts. The 25 positions are fully loaded, so the BOM line count must match exactly; there are no unpopulated positions to work around. Gold GXT plating at 30.0 µin is a robust signal-grade finish — it handles repeated mating cycles and resists corrosion in moderate environments better than tin. The 5 A per circuit rating is typical for signal headers; if you need to push near that limit continuously, derate above 25°C per the standard ampacity curve for the housing material.
