The surface-mount termination and push-pull fastening type mean this header is reflow-soldered to the board and mates without a locking latch — suitable for applications where the mated pair is not subject to continuous vibration or cable strain. ## Gold Mating Finish and Flame-Rated Housing The same Minitek127® 1.27mm dual-row SMT header is also available in 40-position (20021121-00040T4LF) and 60-position (20021121-00060T4LF) variants, with identical pitch, plating, and material specs. The 50-position version sits between these two — the choice is driven by the required signal count on the board edge. For buyers needing tape-and-reel packaging instead of tube, the 20021121-00050C4LF offers the same 50-position header in a reel format suitable for automated pick-and-place assembly.","metaTitle":"20021121-00050T4LF Amphenol ICC Minitek127 1.27mm Header 50","metaDescription":"20021121-00050T4LF Amphenol ICC (FCI) Minitek127 1.27mm pitch unshrouded header, 50 positions, 1A per contact, gold mating finish, SMT, UL94 V-0.","metaKeywords":null},"attributes":{"series":"Minitek127® 1.27mm","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":"Minitek127® 1.27mm","Package":"Tube","Features":"-","Shrouding":"Unshrouded","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":"125VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"-","Ingress Protection":"-","Base Product Number":"20021121","Insulation Material":"Thermoplastic","Number of Positions":"50","Row Spacing - Mating":"0.050\\\" (1.27mm)","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"1A per Contact","Operating Temperature":"-55°C~125°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"0.120\\\" (3.05mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"50.0µin (1.27µm)","Contact Finish Thickness - Mating":"10.0µin (0.25µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9800","priceTiers":[{"qty":1,"price":"$3.98000","currency":"USD"},{"qty":10,"price":"$3.61700","currency":"USD"},{"qty":100,"price":"$3.18720","currency":"USD"},{"qty":500,"price":"$2.70908","currency":"USD"},{"qty":1000,"price":"$2.31069","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b4a8221a1a0e448432747bc41b251553.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/20021121-00050T4LF/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional alternative to 20021121-00050T4LF?","answer":"If your BOM requires exactly 50 positions, the 20021121-00050C4LF is the same header in tape-and-reel packaging."},{"question":"Where can I buy 20021121-00050T4LF?","answer":"Sourced to order against your BOM quantity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/20021121-00050T4LF","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/20021121-00050T4LF when reusing this data.
