The receptacle accepts bottom or top entry, meaning the same part can be loaded on either side of the board — one line item covers both orientations. ## SMT termination and board lock for reflow A pick-and-place pad on the top of the housing lets the vacuum nozzle grab the part without touching the contacts — reduces placement skew on high-speed lines. Contact material is phosphor bronze, a common spring alloy that resists stress relaxation over temperature cycles. Supplied in Tape & Reel (TR) packaging, which is the standard format for SMT pick-and-place feeders.","metaTitle":"91618-317ALF Dubox Board-to-Board Receptacle, 34 Pos","metaDescription":"Amphenol FCI Dubox 91618-317ALF board-to-board receptacle, 34 positions, 2 rows, 0.100\" pitch, gold mating contacts, SMT, 10.81mm 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":"Tape & Reel (TR)","Features":"Board Lock, Pick and Place","Termination":"Solder","Applications":"Automotive, General Purpose, Industrial, Telecommunications","Contact Type":"Female Socket","Contact Shape":"Square","Mounting Type":"Surface Mount","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":"91618","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"34","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"-","Operating Temperature":"-","Mated Stacking Heights":"10.81mm","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":"$3.3428","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f2098f03d6bcdbeb843fc2378ae2e7a5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What header mates with 91618-317ALF?","answer":"This receptacle mates with a 0.100\" pitch, 2-row, square-pin header from the Dubox or BergStik II series — typically a 34-position male pin header with a 10.81mm mated stack height.
