The header body has 10 physical positions but only 9 pins are loaded — one position is intentionally vacant. This is a common keying or selective-loading practice: the missing pin prevents the mating receptacle from being inserted in the wrong orientation or into the wrong header variant. Confirm your mating half is also a 9-circuit receptacle with the corresponding vacant position, or that your board layout accounts for the missing pin. ## Surface-Mount Termination with Pick-and-Place Compatibility The insulation height of 0.220\" (5.60mm) and mating pin length of 0.120\" (3.05mm) set the mated stack height; check your board-to-board spacing against these dimensions.","metaTitle":"20021221-00110C8LF Amphenol ICC Minitek127® 1.27mm Header","metaDescription":"20021221-00110C8LF Amphenol ICC (FCI) Minitek127® 1.27mm pitch, 10-position (9 loaded), shrouded SMT header. 1A per contact, 30µ\" gold GXT™.","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":"Tape & Reel (TR)","Features":"Pick and Place","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":"10","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, GXT™","Contact Length - Mating":"0.120\\\" (3.05mm)","Number of Positions Loaded":"9","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"50.0µin (1.27µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7936","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b4a8221a1a0e448432747bc41b251553.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/20021221-00110C8LF/alternatives.json"},"ai":{"faq":[{"question":"Why does 20021221-00110C8LF have 9 positions loaded out of 10?","answer":"One position is intentionally vacant — this is a keying or selective-loading scheme to prevent mis-mating.
