It is available for order through independent distribution channels; quantities are sourced per RFQ, and current pricing is confirmed at quote time. No official replacement or cross-reference has been issued by the manufacturer. ## Compliance and Material Notes The contact material is phosphor bronze, a standard spring alloy that resists stress relaxation under repeated deflection. Operating temperature range spans -65°C to 125°C, covering automotive underhood and industrial cabinet environments.","metaTitle":"77311-122-19LF Amphenol ICC BERGSTIK Header, 19-Pos, 2.54 mm","metaDescription":"77311-122-19LF Amphenol ICC (FCI) BERGSTIK unshrouded male header, 19 circuits single row, 0.100\" pitch, 3 A per contact, 30 µinch gold 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":"Bag","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":"19","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":"0.525\\\" (13.34mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.305\\\" (7.75mm)","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":"$1.3708","stockQuantity":17,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b7619af15a6f914d234facab530ef078.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pinout of 77311-122-19LF?","answer":"The 77311-122-19LF is a single-row, 19-position header with all positions loaded.
