In a panel or cabinet where the harness is routed near moving parts, this lock prevents the header from backing out of the receptacle. Tin-on-tin contacts at 78.7 µinch thickness are rated for a few dozen mating cycles; for higher reconnect duty, the gold-plated sibling (76383-303LF) is the better choice. ## Position Count vs. Siblings — 8 vs. 6 vs. 4 Within the 76383 series, the 8-position 76383-404LF sits between the 6-position 76383-403LF and the 4-position 76383-402LF. If the BOM calls for 6 circuits, the 76383-403LF is a drop-in replacement on the same footprint; for 4 circuits, the 76383-402LF.","metaTitle":"76383-404LF Amphenol ICC (FCI) Dubox™ Header, 8 Pos, 2.54mm","metaDescription":"76383-404LF — Amphenol ICC (FCI) Dubox™ 8-position, 0.100\" pitch, right-angle header.
