Gold-plated mating contacts (15.0 µin) mate with a 0.100\" pitch header to achieve a mated stack height of 11.04 mm. The through-hole solder termination and push-pull fastening suit bottom- or top-entry board stacking. ## Position count within the Dubox series At 6 positions the 71991-803LF sits at the low end of the Dubox dual-row receptacle family — the 2.54 mm pitch and row spacing, gold mating contacts, and 11.04 mm stack height are shared across the series, so match the position count to the circuit count on the board.","metaTitle":"Amphenol Dubox 71991-803LF Receptacle, 6 Pos, 2.54mm","metaDescription":"Amphenol ICC (FCI) Dubox 71991-803LF receptacle, 6 positions, dual row, 2.54 mm pitch, gold mating contacts, through hole, 11.04 mm stack height.","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, Bottom or Top Entry","Fastening Type":"Push-Pull","Number of Rows":"2","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":"71991","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"6","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.118\\\" (3.00mm)","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":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d12387c44afc462d5fb4943551712d4d.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/71991-803LF/alternatives.json"},"ai":{"faq":[{"question":"What is the mated stack height of the 71991-803LF?","answer":"The mated stack height is 11.04 mm when mated with the matching 0.100\" pitch Dubox header."},{"question":"What compliance documentation is available for the 71991-803LF?","answer":"The housing is rated UL94 V-0.
