Tin contacts are rated for fewer mating cycles than gold — expect 25–50 cycles before wear begins to affect contact resistance. This is fine for one-time assembly or infrequent field service. The board guide assists alignment during assembly, reducing pin damage. The 3-644486-2 is single-row — if your receptacle is a single-row MTA-100, the dual-row part will not fit.","metaTitle":"3-644486-2 TE Connectivity MTA-100 Header 12 Pos 2.54mm","metaDescription":"3-644486-2 TE Connectivity AMP Connectors MTA-100 header, 12 positions, single row, 0.100\" (2.54 mm) pitch, shrouded 4-wall, friction lock, tin contacts, UL94","metaKeywords":null},"attributes":{"series":"MTA-100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 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":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","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":"Black","Insulation Height":"0.410\\\" (10.41mm)","Ingress Protection":"-","Base Product Number":"644486","Insulation Material":"Polyester","Number of Positions":"12","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.140\\\" (3.56mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-55°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"0.440\\\" (11.18mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.200\\\" (5.08mm)","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":"$2.0400","priceTiers":[{"qty":1,"price":"$2.04000","currency":"USD"},{"qty":10,"price":"$1.82000","currency":"USD"},{"qty":100,"price":"$1.64490","currency":"USD"},{"qty":500,"price":"$1.48782","currency":"USD"},{"qty":1000,"price":"$1.33072","currency":"USD"},{"qty":5000,"price":"$1.17362","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/103be8cce9a1dd971e687b0300acd3fa.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-644486-2/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for 3-644486-2?","answer":"The peer 1-1871673-2 has a different pitch (0.098\" vs 0.100\"), different position count (4 vs 12), and a detent lock instead of a friction lock — it is not a form-fit-function replacement.
