The Amphenol 79821-414HLF is a 14-position, dual-row BERGSTIK® II unshrouded header on 0.100" (2.54 mm) pitch — a standard square-pin footprint that drops into legacy through-hole layouts. Tin-plated phosphor bronze contacts, 5 A per circuit, with 100.0 µin (2.54 µm) of tin on the mating surface. The 0.430" (10.92 mm) mating length gives enough wipe for a solid tin-to-tin connection without bottoming out in a standard receptacle. Unshrouded header with no keying wall; push-pull retention relies on pin friction. The 0.730" (18.54 mm) overall contact length and 0.200" (5.08 mm) post length define board separation.
