The single-row layout keeps the wire bundle narrow, which helps in tight enclosures. Mates with MTA-156 receptacle housings that accept 20-24 AWG wire with the matching crimp terminal. Termination is through-hole solder. The contact post length is 0.125\" (3.18 mm), which fits standard 1.6 mm PCBs with enough protrusion for a reliable solder fillet.","metaTitle":"3-644615-7 TE Connectivity MTA-156 Header 7 Pos 3.96mm","metaDescription":"TE Connectivity AMP Connectors MTA-156 header, 7 positions, 0.156\" (3.96 mm) pitch, shrouded, friction lock, tin contacts, UL94 V-0.","metaKeywords":null},"attributes":{"series":"MTA-156","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-156","Package":"Bulk","Features":"Board Guide, Keying Slot","Shrouding":"Shrouded - 1 Wall","Termination":"Solder","Applications":"General Purpose, Industrial","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Friction Lock","Number of Rows":"1","Pitch - Mating":"0.156\\\" (3.96mm)","Product Status":"Active","Voltage Rating":"600VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.545\\\" (13.84mm)","Ingress Protection":"-","Base Product Number":"644615","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"7","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.125\\\" (3.18mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-55°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"0.700\\\" (17.78mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.450\\\" (11.43mm)","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":"$0.9700","priceTiers":[{"qty":1,"price":"$0.97000","currency":"USD"},{"qty":10,"price":"$0.92400","currency":"USD"},{"qty":100,"price":"$0.76090","currency":"USD"},{"qty":500,"price":"$0.69170","currency":"USD"},{"qty":1000,"price":"$0.59811","currency":"USD"},{"qty":5000,"price":"$0.51267","currency":"USD"},{"qty":10000,"price":"$0.50356","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/5d00f8f17e848a774b59033d8592006f.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-644615-7/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the 3-644615-7 connector?","answer":"The 3-644615-7 is sourced through independent distribution channels.
