The gold layer supports repeated mating cycles in field-service or test applications; the tin tails solder cleanly into plated through-holes. Operating temperature range spans -65°C to 130°C, covering most industrial and commercial environments. ## Board Fit and Routing Considerations This geometry suits daughtercard or mezzanine connections where the header sits at the board edge and the mating receptacle approaches from above. The unshrouded design leaves the pins exposed, which simplifies routing access for probing or manual wiring but offers no keying against mis-mating. ## Position Count Options Across the Family The 77317-104-xxLF series covers position counts from 6 to 72 in the same dual-row, right-angle, unshrouded format. The 28-position variant (77317-104-28LF) sits between the 12-position (77317-104-12LF) and 72-position (77317-104-72LF) siblings. Standardising on one series across multiple position counts reduces SKU count without changing the footprint or tooling.","metaTitle":"77317-104-28LF Amphenol ICC BERGSTIK® Header, 28 Pos","metaDescription":"77317-104-28LF Amphenol ICC (FCI) BERGSTIK® unshrouded header, 28 positions, 0.100\" pitch, right-angle through-hole, 3 A per contact, gold GXT™ plating.","metaKeywords":null},"attributes":{"series":"BERGSTIK®","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"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, Right Angle","Connector Type":"Header, Breakaway","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.190\\\" (4.83mm)","Ingress Protection":"-","Base Product Number":"77317","Insulation Material":"Thermoplastic","Number of Positions":"28","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~130°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"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":"$2.2400","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.24000","currency":"USD"},{"qty":10,"price":"$1.94900","currency":"USD"},{"qty":100,"price":"$1.74160","currency":"USD"},{"qty":500,"price":"$1.45130","currency":"USD"},{"qty":1000,"price":"$1.24397","currency":"USD"},{"qty":5000,"price":"$1.10298","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/42c126686d14e9609fbc22c6c8ef2c15.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pinout and row count of 77317-104-28LF?","answer":"All positions are loaded."},{"question":"Where can I buy 77317-104-28LF?","answer":"Availability and current pricing confirmed at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/77317-104-28LF","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/77317-104-28LF when reusing this data.
