The male pins are phosphor bronze with a 100.0µin (2.54µm) tin finish on the mating surface and tin on the solder tails, rated for 5 A per contact at 110 V. The 0.100\" pitch is the defining dimension — it matches the industry-standard 0.025\" square-post footprint, so any 0.100\" pitch female socket or IDC connector with 0.025\" square receptacles is a potential mate.","metaTitle":"FCI 79821-434HLF BERGSTIK II Header, 34 Pos, 0.100\" Pitch","metaDescription":"FCI 79821-434HLF BERGSTIK® II unshrouded header, 34 positions, dual-row, 0.100\" pitch, 5 A, tin plating.
