The solder tails receive a 78.7µinch tin finish for reliable solder joint formation. ## Push-Pull Fastening, Top or Bottom Entry The receptacle accepts top or bottom entry, so the same part works as the upper or lower half of the mezzanine pair. Insulation height is 0.275\" (6.99mm), leaving clearance for components on the opposite board. ## Application Range: Automotive, Industrial, Telecom The 30µinch gold contacts and UL94 V-0 housing support the vibration and thermal cycling typical of industrial control panels and telecom infrastructure.","metaTitle":"91618-311BLF Amphenol ICC Dubox 22-Circuit Board-to-Board","metaDescription":"91618-311BLF Amphenol ICC Dubox 22-circuit dual-row receptacle, 0.100\" pitch, gold mating contacts, 10.81mm stack height, SMT with board lock.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"91618-311BLF","Series":"Dubox™","Package":"Tube","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)","Contact Material":"Phosphor Bronze","Insulation Color":"Gray","Insulation Height":"0.275\\\" (6.99mm)","Base Product Number":"91618","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"22","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","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":"$1.9309","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f2098f03d6bcdbeb843fc2378ae2e7a5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating connector for 91618-311BLF?","answer":"The 91618-311BLF is a receptacle that mates with a Dubox series header of matching pitch (0.100\") and circuit count (22 positions).
