For 18 AWG wire, expect around 7 A per circuit; for 22 AWG, roughly 5 A. The tin-plated contact interface limits the continuous current below what the copper alloy pin can carry — derate for elevated ambient temperature above 85°C. Compared to the 10-position sibling 1-292164-1, this 12-position version adds two circuits in the same single-row footprint — the board space required is 1.56\" (39.6 mm) vs 1.25\" (31.8 mm) for the 10-position. The header mates with MTA-156 receptacle housings (e.g., 3-640441-2 for 12 positions) using the appropriate crimp terminals. Through-hole solder termination with 0.125\" (3.18 mm) post length suits standard 0.062\" (1.6 mm) PCBs.","metaTitle":"4-647615-2 TE Connectivity MTA-156 Header 12 Pos 3.96mm","metaDescription":"4-647615-2 TE Connectivity AMP Connectors MTA-156 series header, 12 positions, 0.156\" (3.96mm) pitch, tin-plated contacts, friction lock.","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","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":"647615","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"12","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":"$2.8200","priceTiers":[{"qty":1,"price":"$2.82000","currency":"USD"},{"qty":10,"price":"$2.51000","currency":"USD"},{"qty":100,"price":"$2.26830","currency":"USD"},{"qty":500,"price":"$2.05168","currency":"USD"},{"qty":1000,"price":"$1.83505","currency":"USD"},{"qty":5000,"price":"$1.61841","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/4-647615-2/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 4-647615-2?","answer":"The 4-647615-2 mates with a 12-position MTA-156 receptacle housing (e.g., TE 3-640441-2) using the appropriate crimp terminals for the wire gauge.
