The tin-plated solder tails are standard for SMT assembly and wet well with lead-free solder paste. The insulation color is black, which is the standard for the Minitek127 series.","metaTitle":"20021221-00020T1LF Amphenol ICC Minitek127 1.27mm SMT Header","metaDescription":"20021221-00020T1LF Amphenol ICC (FCI) Minitek127® 1.27mm dual-row header, 20 positions, SMT, shrouded 4-wall, gold flash contacts.","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":"Minitek127® 1.27mm","Package":"Tube","Features":"-","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":"125VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.220\\\" (5.60mm)","Ingress Protection":"-","Base Product Number":"20021221","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":"Flash"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b4a8221a1a0e448432747bc41b251553.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/20021221-00020T1LF/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 20021221-00020T1LF?","answer":"No official pin-compatible alternative is listed by the manufacturer.
