Confirm the mating header's post length and stacking height against the 11.04 mm specification before committing the BOM; a header with a different stack height will shift the mated assembly out of its intended z-height envelope.","metaTitle":"76341-321LF Dubox 21-Position Receptacle, 0.100\" Pitch","metaDescription":"Amphenol ICC (FCI) Dubox single-row receptacle, 21 circuits, 0.100\" (2.54 mm) pitch, through-hole solder, 30 µ\" gold mating surface, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"Dubox™","Package":"Tube","Features":"-","Termination":"Solder","Applications":"Automotive, General Purpose, Industrial, Telecommunications","Contact Type":"Female Socket","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Receptacle","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Blue","Insulation Height":"0.275\\\" (6.99mm)","Ingress Protection":"-","Base Product Number":"76341","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"21","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.114\\\" (2.90mm)","Current Rating (Amps)":"-","Operating Temperature":"-","Mated Stacking Heights":"11.04mm","Contact Finish - Mating":"Gold","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7211","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/e3711a1c1ef6b3d2e321938057873f50.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 76341-321LF?","answer":"The 76341-321LF is sourced to order through our independent distribution network."},{"question":"What header mates with 76341-321LF?","answer":"This receptacle mates with a 0.100\" pitch, single-row, 21-position pin header that provides an 11.04 mm mated stack height.

For a 0.100\" pitch, single-row contact with gold plating, typical per-contact current is in the 3 A range at 25 °C ambient, but derating depends on the number of adjacent circuits and the PCB copper geometry.
