The 0.095\" (2.41 mm) post length below the housing provides enough standoff for solder fillet inspection on a standard 0.062\" PCB. The base product number is 77311; the -101 suffix denotes the specific plating and post-length variant. No official pin-compatible replacement from Amphenol ICC (FCI) exists — this is the current production version. The tin-plated posts are solderable with lead-free or leaded processes.","metaTitle":"77311-101-32LF BERGSTIK Header, 32 Pos, 0.100\" Pitch","metaDescription":"Amphenol ICC (FCI) 77311-101-32LF BERGSTIK single-row unshrouded header, 32 positions, 0.100\" pitch, 3 A per contact, gold mating finish.
