Tin-plated mating contacts at 78.7µin thickness, a 2.54 mm pitch, and an 11.04 mm mated stack height define the footprint and signal routing density. The glass-filled thermoplastic housing carries a UL94 V-0 flammability rating and is colour-coded blue for visual identification on the board. ## Position count and stack height The 26 positions of the 71991-413LF are fully loaded across two rows spaced 0.100\" (2.54 mm) apart, matching the mating pitch. The 11.04 mm mated stacking height is fixed by the receptacle design — the board-to-board gap is set by this value plus the mating header's post length.","metaTitle":"Amphenol Dubox 71991-413LF Receptacle, 26-Pos, 2.54mm","metaDescription":"Amphenol ICC (FCI) Dubox 71991-413LF: 26-position dual-row receptacle, 2.54 mm pitch, 11.04 mm stack height, tin mating contacts, through-hole solder","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":"26","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":"Tin","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"78.7µin (2.00µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1588","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d12387c44afc462d5fb4943551712d4d.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/71991-413LF/alternatives.json"},"ai":{"faq":[{"question":"What is the mated stack height for the 71991-413LF?","answer":"The 71991-413LF provides an 11.04 mm mated stacking height when paired with the matching Dubox header.
