The 1.27 mm pitch and 0.050\" row spacing let you route two signals per row in a tight board-to-board mezzanine stack — the 0.120\" (3.05 mm) mating pin length sets the mated height above the PCB. The gold mating finish (10 µinch) keeps contact resistance stable over repeated mating cycles — a solid choice for signal-level interconnects where the board stack is accessed during test or field service. Surface-mount termination with tin-plated posts (50 µinch) — the SMD tails reflow alongside other board components, saving a wave-solder pass. Unshrouded male pins with a square contact shape — mates with a Minitek127 1.27mm receptacle (sold separately). Push-pull fastening; no locking latch, so plan for a secondary retention method if the assembly sees vibration. All 16 positions are loaded.","metaTitle":"20021121-00016T4LF – Amphenol ICC Minitek127 1.27mm Header","metaDescription":"20021121-00016T4LF – Amphenol ICC (FCI) Minitek127 1.27mm dual-row header, 16 positions, SMD, gold mating finish, 1A per contact.","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":"16","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":"$1.4600","priceTiers":[{"qty":1,"price":"$1.46000","currency":"USD"},{"qty":10,"price":"$1.23700","currency":"USD"},{"qty":100,"price":"$1.11030","currency":"USD"},{"qty":500,"price":"$0.90846","currency":"USD"},{"qty":1000,"price":"$0.80752","currency":"USD"},{"qty":5000,"price":"$0.70658","currency":"USD"},{"qty":10000,"price":"$0.67125","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b4a8221a1a0e448432747bc41b251553.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/20021121-00016T4LF/alternatives.json"},"ai":{"faq":[{"question":"Is 20021121-00016T4LF suitable for board-to-board stacking?","answer":"Yes — the listed style is Board to Board.
