The mated stack height is 11.04mm, which sets the board-to-board spacing when paired with a matching Dubox header. The receptacle accepts bottom or top entry mating, giving flexibility in board stacking orientation. ## Tin-Plated Contacts and Termination Details This is a heavier tin deposit than typical flash tin — it provides decent wear for moderate mating cycles (50-100) and resists corrosion in industrial environments without the cost of gold. The contact length on the post side is 0.118\" (3.00mm) — enough for a through-hole solder joint on a standard 1.6mm PCB. Termination is solder only — no press-fit option. The connector ships in a tube, which is typical for through-hole parts that need hand or wave soldering.","metaTitle":"71991-411LF Dubox Receptacle, 22-Pin 2.54mm Pitch","metaDescription":"Amphenol ICC (FCI) 71991-411LF Dubox series receptacle, 22 positions, 0.100\" (2.54mm) pitch, tin-plated contacts, through-hole, 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, 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":"22","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":"$1.8161","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d12387c44afc462d5fb4943551712d4d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating header for the 71991-411LF?","answer":"The 71991-411LF is a Dubox series receptacle.
