The 640455-3 is identical in every spec except the base product number. Both are 3-position, right-angle, tin-plated headers with the same footprint and friction lock. For a BOM line requiring a straight solder tail, the 644875-3 is the direct match.","metaTitle":"644875-3 TE Connectivity MTA-100 Header 3 Pos 2.54mm Right","metaDescription":"644875-3 TE Connectivity AMP Connectors MTA-100 header, 3 positions, 0.100\" (2.54mm) pitch, right-angle through-hole, tin contacts, friction lock, UL94 V-0.","metaKeywords":null},"attributes":{"series":"MTA-100","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Cable/Wire","Series":"MTA-100","Package":"Bulk","Features":"-","Shrouding":"Shrouded - 1 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Friction Lock","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"250VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.225\\\" (5.72mm)","Ingress Protection":"-","Base Product Number":"644875","Insulation Material":"Thermoplastic","Number of Positions":"3","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.135\\\" (3.43mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-55°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.295\\\" (7.49mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6100","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.61000","currency":"USD"},{"qty":10,"price":"$0.58900","currency":"USD"},{"qty":100,"price":"$0.47500","currency":"USD"},{"qty":500,"price":"$0.42056","currency":"USD"},{"qty":1000,"price":"$0.36861","currency":"USD"},{"qty":5000,"price":"$0.32161","currency":"USD"},{"qty":10000,"price":"$0.29934","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the pinout of the 644875-3?","answer":"The 644875-3 is a single-row, 3-position header with all positions loaded.
