The tin-plated solder tails (50µin) are standard for SMT reflow; the gold is only where the contact wipes. Lifecycle status is Active with ROHS3 compliance — no end-of-life notice, no lead-free exemption expiry to track. ## Mating Half and Board-to-Board Fit As an unshrouded header, this mates with any Minitek127 1.27mm pitch receptacle that has 20 positions in a dual-row layout — typically a socket with a similar pin-out. The 0.120\" (3.05mm) mating pin length gives enough wipe for a standard receptacle contact beam — the receptacle should have a mating depth of at least 3mm to fully engage the gold interface. ## What It Does Not Do — And Why That Matters This is a signal header, not a power interconnect. The unshrouded design also means no polarization keying; if the mating receptacle is inserted backwards, the pins can bend. Verify orientation in the assembly fixture.","metaTitle":"20021121-00020C4LF Amphenol ICC Minitek127 1.27mm 20-Pin","metaDescription":"Amphenol ICC Minitek127 1.27mm 20-position dual-row SMT header, 1A per contact, 10µin gold mating finish, pick-and-place, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"Minitek127® 1.27mm","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"Minitek127® 1.27mm","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Pick and Place","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":"20","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":"$1.8500","priceTiers":[{"qty":1,"price":"$1.85000","currency":"USD"},{"qty":10,"price":"$1.61000","currency":"USD"},{"qty":100,"price":"$1.43850","currency":"USD"},{"qty":600,"price":"$1.19872","currency":"USD"},{"qty":1200,"price":"$1.02748","currency":"USD"},{"qty":1800,"price":"$0.99322","currency":"USD"},{"qty":3000,"price":"$0.95897","currency":"USD"},{"qty":6000,"price":"$0.91103","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b4a8221a1a0e448432747bc41b251553.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/20021121-00020C4LF/alternatives.json"},"ai":{"faq":[{"question":"What receptacle mates with this 20-position header?","answer":"Any Minitek127 1.27mm pitch, 20-position, dual-row receptacle socket.
