Mating contacts carry a gold or Gold, GXT™ finish at 30.0µin (0.76µm) thickness; the through-hole solder posts are tin-plated at 78.7µin (2.00µm). Rated 3 A per contact with a UL94 V-0 thermoplastic housing. ## Board-to-board fit and routing notes Unshrouded push-pull fastening mates with standard 0.100\" (2.54 mm) pitch receptacles. The 0.335\" (8.51 mm) mating pin length and 0.100\" (2.54 mm) post length set the board-to-board stack height — match the receptacle's insulation height to the mating pin exposure. Single-row layout with all 18 positions loaded keeps the board footprint narrow for dense routing. The square pin contact shape provides consistent wipe and retention across mating cycles.","metaTitle":"Amphenol BERGSTIK 77311-115-18LF Header, 18 Pos 2.54mm","metaDescription":"Amphenol ICC (FCI) BERGSTIK header 77311-115-18LF: 18 positions, single row, 0.100\" (2.54 mm) pitch, 3 A per contact, through-hole, gold GXT mating finish.","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":"18","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.100\\\" (2.54mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~125°C","Mated Stacking Heights":"-","Overall Contact Length":"0.535\\\" (13.59mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.335\\\" (8.51mm)","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":"$1.1303","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b7619af15a6f914d234facab530ef078.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/77311-115-18LF/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation is available for the 77311-115-18LF?","answer":"The housing carries a UL94 V-0 flammability rating.
