No IP rating is listed — this is an unsealed header, so it's not for washdown or outdoor direct-spray locations without a conformal coating or sealed mating half.","metaTitle":"91687-312LF Amphenol ICC Dubox Header – 24 Pos, 0.100\" Pitch","metaDescription":"Amphenol ICC (FCI) Dubox 91687-312LF: 24-circuit, dual-row shrouded header, 0.100\" pitch, 3 A, gold GXT mating, through-hole, active production.","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 Cable/Wire","Series":"Dubox™","Package":"Tube","Features":"-","Shrouding":"Shrouded - 2 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Friction Lock","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Blue","Insulation Height":"0.368\\\" (9.35mm)","Ingress Protection":"-","Base Product Number":"91687","Insulation Material":"Polyester, Glass Filled","Number of Positions":"24","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.134\\\" (3.40mm)","Current Rating (Amps)":"3A","Operating Temperature":"-40°C~125°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold, GXT™","Contact Length - Mating":"0.197\\\" (5.00mm)","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":"$2.4908","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/ab28b88bf1eff109e46594290310b98e.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/91687-312LF","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/91687-312LF when reusing this data.
