Mating contacts carry a 30.0µin (0.76µm) gold or GXT finish — the GXT option provides extended durability for repeated mate-unmate cycles in board-to-board interconnects. Rated 3A per contact with a phosphor bronze base, the header operates from -65°C to 125°C and uses a UL94 V-0 black thermoplastic insulator. ## Position count & pitch across the series At 33 positions, this header occupies a 0.100\" (2.54mm) pitch single-row footprint — the same pitch used across the BERGSTIK line. The 33-circuit count sits above the common 20- and 30-position variants, suiting applications that need an odd circuit count without moving to a dual-row layout.","metaTitle":"Amphenol ICC 77311-102-33LF BERGSTIK Header, 33 Pos","metaDescription":"Amphenol ICC (FCI) BERGSTIK header 77311-102-33LF: 33 positions, single row, 0.100\" (2.54mm) pitch, 3A per contact, gold GXT mating finish, through-hole solder","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":"33","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.135\\\" (3.43mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~125°C","Mated Stacking Heights":"-","Overall Contact Length":"0.465\\\" (11.81mm)","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":"$1.5189","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b7619af15a6f914d234facab530ef078.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/77311-102-33LF/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation is available for 77311-102-33LF?","answer":"The header carries a UL94 V-0 flammability rating on the thermoplastic insulator.
