That wide thermal window suits equipment that sees thermal cycling — industrial control cabinets, test fixtures, or telecom line cards. ## Right-Angle Routing — Board-Edge Fit Unshrouded push-pull fastening means there's no locking latch; vibration resistance depends entirely on the mating receptacle's retention force. Row spacing is also 0.050\" (1.27mm), so the dual-row footprint is compact — 0.100\" (2.54mm) overall width across both rows. The contact length after the bend is 0.106\" (2.69mm) post, which gives a reasonable solder fillet height on a standard 1.6mm board. It's RoHS compliant. ## Position Count vs Siblings — 20 vs 16 vs 12 The 20021112-00020T4LF is the 20-position variant in the Minitek127 right-angle unshrouded header family. Direct peers include the 20021112-00016T4LF (16 positions) and 20021112-00012T4LF (12 positions) — same pitch, same gold mating finish, same 1 A rating. The only difference is the pin count, so the footprint length scales accordingly. If the BOM calls for 16 circuits, the 16-position sibling is a drop-in fit on the same row spacing.","metaTitle":"20021112-00020T4LF Amphenol ICC Minitek127 20-Pin","metaDescription":"Amphenol ICC Minitek127 1.27mm pitch, 20-position dual-row unshrouded header, through-hole right-angle, gold mating finish, rated 1A per contact, 125VAC.","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":"Through Hole, Right Angle","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":"0.135\\\" (3.43mm)","Ingress Protection":"-","Base Product Number":"20021112","Insulation Material":"Thermoplastic","Number of Positions":"20","Row Spacing - Mating":"0.050\\\" (1.27mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.106\\\" (2.69mm)","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":"$1.5500","priceTiers":[{"qty":1,"price":"$1.55000","currency":"USD"},{"qty":10,"price":"$1.35300","currency":"USD"},{"qty":100,"price":"$1.20940","currency":"USD"},{"qty":500,"price":"$1.00782","currency":"USD"},{"qty":1000,"price":"$0.86385","currency":"USD"},{"qty":5000,"price":"$0.76595","currency":"USD"},{"qty":10000,"price":"$0.74867","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f116c3f0e480eebf6161f7ad303f4e48.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/20021112-00020T4LF/alternatives.json"},"ai":{"faq":[{"question":"What is the closest alternative if I need fewer positions?","answer":"The 20021112-00016T4LF (16 positions) and 20021112-00012T4LF (12 positions) are identical in pitch, plating, current rating, and mounting — just fewer circuits.
