Tin is a reliable, low-cost finish for applications with fewer than 50 mating cycles and no exposure to corrosive atmospheres. The square male pins measure 0.200\" (5.08mm) mating length and 0.130\" (3.30mm) post length, fitting standard 0.025\" square-post receptacles common in the MTA-100 ecosystem. ## Mates with MTA-100 IDC Receptacles and Crimp Housings The 8-position, 0.100\" pitch, single-row layout mates directly with MTA-100 IDC receptacles (e.g., 640445-8) and crimp-style receptacle housings. Confirm the mating half's position count and keying — this header is not keyed, so it accepts unkeyed or polarized receptacles with the corresponding lock feature.","metaTitle":"2-644488-8 TE Connectivity MTA-100 Header, 8 Pos","metaDescription":"2-644488-8 TE Connectivity AMP Connectors MTA-100 header, 8 positions, 0.100\" pitch, right-angle through-hole, tin plating, friction lock, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Cable/Wire","Series":"MTA-100","Package":"Bulk","Features":"-","Shrouding":"Shrouded - 4 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":"Black","Insulation Height":"0.343\\\" (8.71mm)","Ingress Protection":"-","Base Product Number":"644488","Insulation Material":"Polyester","Number of Positions":"8","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.130\\\" (3.30mm)","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":"0.200\\\" (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":"$1.0211","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/81d605b30dd155ee70162f41dd9bb683.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 2-644488-8 and what is the lead time?","answer":"2-644488-8 is an active TE Connectivity part."},{"question":"What is the difference between 2-644488-8 and 2-644488-7?","answer":"The difference is position count: 2-644488-8 has 8 positions, while 2-644488-7 has 7 positions.
