Supplied in tube packaging for through-hole assembly lines. The base product number 68683 covers the Dubox™ receptacle family — confirm the position count and plating option against the BOM line before committing. In a vibration-prone assembly, a locking header variant or board-mount retention is worth evaluating. The square contact shape (0.025\" square typical for Dubox™) mates with the header's square pin — confirm the header pin profile matches.","metaTitle":"68683-321 Dubox™ 42-Position Board-to-Board Receptacle","metaDescription":"68683-321 Amphenol ICC (FCI) Dubox™ receptacle, 42 circuits, 2.54mm pitch, 30µin gold mating finish, 1000V rating, active production.
