The connector is a bottom or top entry style with a push-pull fastening, and the board lock feature holds it in place during SMT reflow, resisting shear from cable strain in the final assembly. The mated stack height is 10.81mm, which defines the z-height budget for mezzanine board spacing — confirm this matches your board-to-board gap before layout. ## Gold Mating Finish and Board Lock for Reliable SMT Assembly The board lock feature provides mechanical retention during reflow and adds shear resistance once soldered, which is useful when the receptacle is mated to a header that sees cable strain. ## Dubox Series Positioning and Application Range","metaTitle":"91618-312LF Amphenol ICC Dubox 24-Position Board-to-Board","metaDescription":"Amphenol ICC Dubox 91618-312LF: 24-position, 0.100\" pitch, dual-row board-to-board receptacle, 30.0µin gold mating, 10.81mm stack height, board lock, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"91618-312LF","Series":"Dubox™","Package":"Tube","Features":"Board Lock","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":"24","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":"$2.2429","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f2098f03d6bcdbeb843fc2378ae2e7a5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mated stack height of 91618-312LF?","answer":"The mated stack height is 10.81mm.
