If the BOM calls for 4 circuits, 78548-204HLF is the correct pick; the 2-position part leaves two pads empty. For applications that need higher mating cycle life, 68491-104HLF carries 30.0 µinch gold (double the thickness) at the same 4-position, 0.100\" pitch layout. The thicker gold raises the cycle rating but the footprint and pinout are identical — a drop-in swap if the budget allows. The 72-position sibling 67997-272HLF shares the same plating and pitch but is a different part entirely for high-density backplane use — not a cross-shop for a 4-circuit BOM line. Kinked-pin solder termination — the kink in the post provides a press-fit retention in the plated through-hole before wave soldering, holding the header in place during assembly. Plan the z-height budget accordingly.","metaTitle":"78548-204HLF BERGSTIK II Header, 4 Pos, 2.54 mm Pitch","metaDescription":"Amphenol ICC (FCI) 78548-204HLF BERGSTIK II unshrouded header, 4 circuits, 0.100\" (2.54 mm) pitch, 15 µinch gold plating.
