It carries a 0.100\" (2.54 mm) pitch, 3 A per contact rating, gold or GXT plating on the mating side, and through-hole solder termination for manual or wave-solder assembly. ## Unshrouded fit and board layout With no shroud around the pins, the 0.100\" (2.54 mm) insulation height leaves the mating interface exposed — the board footprint keeps the same 2.54 mm pitch as the rest of the BERGSTIK series, so the row spacing and hole pattern are consistent across sibling position counts. The single-row layout and 0.118\" (3.00 mm) post length fit standard 1.6 mm PCBs; the UL94 V-0 thermoplastic housing handles the soldering thermal profile without distortion.","metaTitle":"77311-883-20LF Amphenol BERGSTIK Header 20 Pos 2.54mm","metaDescription":"Amphenol ICC (FCI) BERGSTIK 77311-883-20LF: 20 positions, single row, 0.100\" (2.54 mm) pitch, 3 A per contact, gold 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":"20","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.118\\\" (3.00mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~125°C","Mated Stacking Heights":"-","Overall Contact Length":"1.024\\\" (26.00mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.805\\\" (20.45mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5258","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b7619af15a6f914d234facab530ef078.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/77311-883-20LF/alternatives.json"},"ai":{"faq":[{"question":"What is 77311-883-20LF's listed style on this Pin Headers, Sockets & Housings line?","answer":"The style is Board to Board, reflecting its use as a through-hole male header for stacking two PCBs with a push-pull mating interface."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/77311-883-20LF","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/77311-883-20LF when reusing this data.
