The pick-and-place feature allows automated assembly. ## Board Fit and Stack Height Constraints The 10.81mm mated stack height is the dimension to design for when spacing two parallel PCBs. The receptacle accepts either bottom or top entry from the mating header, giving flexibility in board orientation. The board lock features are small metal tabs that solder to the PCB, anchoring the connector against the shear force from cable strain during assembly or handling. Without them, the SMT joints alone would carry the full mechanical load. The base product number is 91615.","metaTitle":"91615-310ALF Amphenol ICC Dubox™ 20-Position Board-to-Board","metaDescription":"91615-310ALF – Amphenol ICC Dubox™ 20-position dual-row receptacle, 0.100\" pitch, 30.0µin gold mating, SMT with board locks, 10.81mm stack height, 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":"91615-310ALF","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)","Contact Material":"Phosphor Bronze","Insulation Color":"Gray","Insulation Height":"0.275\\\" (6.99mm)","Base Product Number":"91615","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"20","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":"$1.9106","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6edb469624dc4351dd8434a0ca26c6a8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between 91615-310ALF and 91615-310LF?","answer":"The difference is in the plating and packaging. The 310LF variant typically has a different plating grade (often tin or lower gold thickness) and may ship in tube packaging. Confirm the exact 310LF spec against your BOM before substituting."},{"question":"What is the mating connector for 91615-310ALF?","answer":"The 91615-310ALF is a receptacle that mates with a Dubox™ series header of the same pitch (0.100\") and row count. The mating header must have a pin length that achieves the 10.81mm stacking height. The exact mating part number depends on the header's pin count, plating, and termination style — match the circuit count and orientation to your board layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/91615-310ALF","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/91615-310ALF when reusing this data.
