That vacant position acts as a built-in keying feature, preventing mis-mating with a receptacle that expects a full 8-way pin field. The 1.27mm pitch and 0.050\" row spacing set a compact board footprint — roughly half the density of a standard 0.100\" header. ## Current and Environmental Ratings The gold mating finish (10µinch) on a copper alloy contact gives good corrosion resistance and stable contact resistance over repeated mating cycles, suitable for board-to-board applications where the connector stays mated for the product life. ## Comparing to the Full-Loaded Sibling The closest functional alternative is 20021221-00008T4LF — identical in pitch, plating, current rating, and SMT footprint, but with all 8 positions loaded. If your mating receptacle has a full 8-way pin field and you do not need the keying from the vacant position, the 00008T4LF is a drop-in replacement. The 6-position variant (20021221-00006T4LF) shares the same specs for lower circuit-count designs.","metaTitle":"20021221-00108D4LF Amphenol ICC Minitek127 1.27mm Header","metaDescription":"20021221-00108D4LF Amphenol ICC (FCI) Minitek127 1.27mm pitch SMT header, 8 positions (7 loaded), gold mating finish, 1A/contact, 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":"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":"8","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":"7","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":"$1.4900","priceTiers":[{"qty":1,"price":"$1.49000","currency":"USD"},{"qty":10,"price":"$1.29500","currency":"USD"},{"qty":100,"price":"$1.15740","currency":"USD"},{"qty":500,"price":"$0.96452","currency":"USD"},{"qty":1000,"price":"$0.82674","currency":"USD"},{"qty":5000,"price":"$0.73304","currency":"USD"},{"qty":10000,"price":"$0.71650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b4a8221a1a0e448432747bc41b251553.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/20021221-00108D4LF/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 20021221-00108D4LF?","answer":"This is a male pin header from the Minitek127® 1.27mm series.
