Mating contacts are gold or gold GXT™ plated (30.0µin / 0.76µm) over phosphor bronze; solder tails are tin (78.7µin / 2.00µm). Rated 3A per contact, -65°C to 125°C, UL94 V-0 thermoplastic housing. ## Through-hole termination, push-pull fastening Termination is through-hole solder; the 0.120\" (3.05mm) post length suits standard PCB thickness. Mating contact length is 0.230\" (5.84mm), overall contact length 0.450\" (11.43mm). Fastening is push-pull — no locking latch. ## Active production, bulk packaging Ships in bulk (tube or tray depending on factory lot). Quoted to order against BOM quantity; lead time confirmed at RFQ.","metaTitle":"77311-118-31LF Amphenol ICC BERGSTIK Header, 31 Pos, 2.54mm","metaDescription":"Amphenol ICC BERGSTIK 77311-118-31LF: 31-position single-row header, 0.100\" pitch, 3A per contact, gold GXT mating, through-hole solder, UL94 V-0, -65°C to","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":"BERGSTIK®","Package":"Bulk","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"77311","Insulation Material":"Thermoplastic","Number of Positions":"31","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~125°C","Mated Stacking Heights":"-","Overall Contact Length":"0.450\\\" (11.43mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.230\\\" (5.84mm)","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":"$1.4709","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b7619af15a6f914d234facab530ef078.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/77311-118-31LF/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation is available for 77311-118-31LF?","answer":"The housing carries UL94 V-0 flammability rating.
