The mating contacts carry 40.0µin (1.02µm) of gold — thick enough for the field-service reconnect duty typical of a through-hole board-to-board interconnect. Post-side gold is flash-plated, which keeps the solder joint reliable without over-specifying the contact finish on the termination end.","metaTitle":"65781-021 Amphenol ICC Dubox 42-Pos 2.54mm Female Socket","metaDescription":"Amphenol ICC (FCI) Dubox 65781-021 receptacle, 42 positions, dual row, 2.54 mm pitch, gold mating contacts, through-hole solder termination, UL94 V-0.","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":"Bulk","Features":"-","Termination":"Solder","Applications":"-","Contact Type":"Female Socket","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Receptacle","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.335\\\" (8.51mm)","Ingress Protection":"-","Base Product Number":"65781","Insulation Material":"Polyester, Glass Filled","Number of Positions":"42","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Gold","Contact Length - Post":"0.140\\\" (3.56mm)","Current Rating (Amps)":"-","Operating Temperature":"-","Mated Stacking Heights":"-","Contact Finish - Mating":"Gold","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"Flash","Contact Finish Thickness - Mating":"40.0µin (1.02µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.6080","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9bda002383cb1b4649d648920cf897d3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/65781-021/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 65781-021 in the Dubox family?","answer":"No same-series peer with a different position count or plating grade is listed in the parametric data.
