It's a board-to-board interconnect — the male pins mate with a matching receptacle to bridge two PCBs or connect a wire harness. The 0.100\" (2.54 mm) pitch is the standard breadboard spacing, so the footprint fits common perfboard and prototyping layouts. Tin-plated phosphor bronze contacts carry 5 A per circuit, and the through-hole solder tails give a solid mechanical anchor on the board. ## What the ratings mean for the fit The 0.100\" pitch and dual-row layout are the first fit check — the board footprint must match the 24 through-holes at that spacing. The 5 A per contact rating is for signal-level current or low-power distribution; the limiting factor is the narrow pin cross-section and the tin plating, not the housing. Tin contacts at 100.0 µinch thickness are fine for a few dozen mating cycles in a one-time assembly or occasional rework, but not for frequent field reconnects where gold would be specified. The unshrouded design means there's no plastic wall around the pins — the mating receptacle provides the polarization and keying, so the header itself is just a row of square pins.","metaTitle":"FCI BERGSTIK II 87901-424HLF Header, 24 Pos, 0.100\" Pitch","metaDescription":"FCI BERGSTIK® II unshrouded header, 24 positions, 0.100\" (2.54 mm) pitch, tin-plated contacts rated 5 A.
