Mated stack height is 8.26 mm, with the insulator standing 7.57 mm above the board. That z-height budget fits standard mezzanine card spacing in 1U enclosures. The shrouded 4-wall header includes a board guide to align the mating receptacle during blind-mate assembly — saves bent pins on the production line. ## Current, Plating, and Temperature Envelope The solder tail gets a 100 µinch tin finish for a reliable SMT joint. Operating range from -55°C to 130°C with a UL94 V-0 glass-filled thermoplastic housing. Suitable for outdoor telecom cabinets and industrial control where the ambient cycles through freezing to hot.","metaTitle":"93289-140LF Amphenol ICC Rib-Cage III 80-Position 1.27mm","metaDescription":"93289-140LF — 80-position, dual-row, 1.27 mm pitch SMT header from Rib-Cage III series. 1 A per contact, 30 µinch gold mating face, 8.26 mm stack height.","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":"Rib-Cage™ III","Package":"Tube","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.050\\\" (1.27mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"-","Insulation Color":"Natural","Insulation Height":"0.298\\\" (7.57mm)","Ingress Protection":"-","Base Product Number":"93289","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"80","Row Spacing - Mating":"0.050\\\" (1.27mm)","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"1A per Contact","Operating Temperature":"-55°C~130°C","Mated Stacking Heights":"8.26mm","Overall Contact Length":"-","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.130\\\" (3.30mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.3758","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/731b3cee66723ea6cf4ca02249714427.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of 93289-140LF?","answer":"1.27 mm (0.050\") pitch on both the mating interface and the row spacing."},{"question":"Is 93289-140LF RoHS compliant?","answer":"The part number suffix LF indicates lead-free / RoHS-compliant construction."},{"question":"What is the mated stack height for 93289-140LF?","answer":"8.26 mm mated stack height with the matching receptacle."},{"question":"Does 93289-140LF have a board guide?","answer":"Yes — the header includes a board guide feature to assist alignment during blind-mate assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/93289-140LF","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/93289-140LF when reusing this data.
