For applications requiring vibration-resistant locking, the shrouded sibling with a friction lock is the better choice. For simple, low-cost board-to-wire interconnects where space is tight, the unshrouded 4-644457-2 fits.","metaTitle":"4-644457-2 TE Connectivity MTA-100 Header, 12 Pos","metaDescription":"TE Connectivity AMP 4-644457-2 MTA-100 unshrouded pin header, 12 circuits, 0.100\" pitch, through-hole right-angle, tin plating, 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":"Unshrouded","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"-","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":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"644457","Insulation Material":"Thermoplastic","Number of Positions":"12","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.110\\\" (2.79mm)","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":"0.260\\\" (6.60mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"150.0µin (3.81µm)","Contact Finish Thickness - Mating":"150.0µin (3.81µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0900","priceTiers":[{"qty":1,"price":"$1.09000","currency":"USD"},{"qty":10,"price":"$1.01900","currency":"USD"},{"qty":100,"price":"$0.87690","currency":"USD"},{"qty":500,"price":"$0.77260","currency":"USD"},{"qty":1000,"price":"$0.69203","currency":"USD"},{"qty":5000,"price":"$0.62567","currency":"USD"},{"qty":10000,"price":"$0.58663","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c6d677044909ef2e6cccd287eff89642.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/4-644457-2/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of TE 4-644457-2?","answer":"The pitch is 0.100\" (2.54 mm), standard for the MTA-100 series."},{"question":"Is 4-644457-2 RoHS compliant?","answer":"Yes, it is RoHS compliant."},{"question":"What is the current rating of 4-644457-2?","answer":"The current rating varies by wire gauge used in the mating receptacle — refer to the MTA-100 derating curves for your specific conductor size."},{"question":"What is the closest functional second-source for 4-644457-2?","answer":"The 3-644457-3 is the same series, unshrouded, right-angle, tin-plated, but with only 3 positions.
