The 0.100\" (2.54 mm) pitch matches the standard DIP IC footprint — your PCB layout can use a conventional through-hole pattern with 0.100\" row spacing. The overall contact length is 1.040\" (26.42 mm), with a mating length of 0.820\" (20.83 mm) and a post length of 0.120\" (3.05 mm) — the post length determines how far the pin protrudes through the board for soldering. Tin-plated contacts are cost-effective for one-and-done or low-cycle-count interconnects — think a permanent board-to-board stack where the header gets mated once during assembly and stays put. This is a standard BERGSTIK II catalog part, so it's a safe BOM line for production builds. No official cross-reference or direct substitute is on record — if you need an alternative, look at other 38-position, 0.100\" pitch unshrouded headers in the same series with the same post length.","metaTitle":"FCI 87901-438HLF BERGSTIK II Header, 38 Pos, 2.54mm Pitch","metaDescription":"FCI BERGSTIK II unshrouded header, 38 positions, 0.100\" pitch, 5 A, tin-plated, UL94 V-0.
