The mated stack height is 11.04mm — that is the z-height from the top of the mating header's PCB to the bottom of the receptacle's PCB, so plan the board spacing around that single value, not a range. ## Tin Contacts at 78.7µin — Thick Enough for Moderate Cycling The contact base is phosphor bronze, a standard spring alloy that holds its shape over repeated insertions without taking a set. ## Through-Hole Solder, UL94 V-0 Housing Packaging is tube — not tape-and-reel, so if you are running a pick-and-place line, you will need a tube feeder or a manual load step.","metaTitle":"71991-406HLF Dubox Receptacle, 12 Pos, 0.100\" Pitch, Tin","metaDescription":"Amphenol ICC (FCI) Dubox 71991-406HLF: 12-position dual-row receptacle, 0.100\" (2.54mm) pitch, through-hole, tin contacts, 11.04mm 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":"Gray","Insulation Height":"0.275\\\" (6.99mm)","Ingress Protection":"-","Base Product Number":"71991","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"12","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":"$1.4496","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d12387c44afc462d5fb4943551712d4d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 71991-406HLF and how do I get a price?","answer":"The 71991-406HLF is sourced through independent distribution against an RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/71991-406HLF","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/71991-406HLF when reusing this data.
