The mating side is unshrouded — the pins are exposed. The mating receptacle (MTA-100 IDC, sold separately) latches onto the pins; the header itself has no locking feature.","metaTitle":"3-644456-2 TE Connectivity MTA-100 Header 2-Pin 2.54mm Tin","metaDescription":"3-644456-2 TE Connectivity AMP Connectors MTA-100 series unshrouded header, 2 positions, 0.100\" (2.54mm) pitch, through-hole, tin plating.","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":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","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":"644456","Insulation Material":"Thermoplastic","Number of Positions":"2","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":"0.505\\\" (12.83mm)","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":"150.0µin (3.81µm)","Contact Finish Thickness - Mating":"150.0µin (3.81µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2000","priceTiers":[{"qty":1,"price":"$0.20000","currency":"USD"},{"qty":10,"price":"$0.17100","currency":"USD"},{"qty":100,"price":"$0.15570","currency":"USD"},{"qty":500,"price":"$0.12082","currency":"USD"},{"qty":1000,"price":"$0.11230","currency":"USD"},{"qty":5000,"price":"$0.09950","currency":"USD"},{"qty":10000,"price":"$0.08813","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/305c50b34b3f718eb64ff1129ed620d7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-644456-2/alternatives.json"},"ai":{"faq":[{"question":"Is 3-644456-2 RoHS compliant?","answer":"Yes, the part is ROHS3 compliant per the manufacturer's listing."},{"question":"Can 3-644456-2 be used for wire-to-board applications?","answer":"Yes, the style is Board to Cable/Wire.
