Buyers should confirm BOM requirements and plan for a board-level redesign or a cross-reference to an active equivalent. The tin-lead finish means this part is not RoHS compliant for lead-free processes. The SMT termination requires a reflow profile compatible with tin-lead solder; the board footprint follows the 0.100\" grid with two rows. For applications requiring frequent reconnection, a gold-plated variant would be preferred.","metaTitle":"95278-401-40 BERGSTIK® Header, 40 Pos, 0.100\" Pitch, SMT","metaDescription":"Amphenol ICC (FCI) 95278-401-40 BERGSTIK® unshrouded header, 40 positions, 0.100\" pitch, SMT, tin-lead plating.
