The part is ROHS3 compliant, and the base product number 644615 covers the series variant. ## Peer Alternatives in the MTA-156 Series Compared to the 1-1871673-2 (also MTA-156, 4 positions, vertical), the 3-644615-4 shares the same pitch, row count, and friction lock — the difference is in contact finish thickness and packaging. The 953440-3 is a 3-position variant for lower circuit-count applications. The 1-292164-1 is a right-angle version, which changes the board-edge routing and z-height profile.","metaTitle":"3-644615-4 TE Connectivity MTA-156 Header 4 Pos 3.96mm","metaDescription":"3-644615-4 TE Connectivity AMP Connectors MTA-156 header, 4 positions, 3.96mm pitch, through-hole, tin plating, friction lock.","metaKeywords":null},"attributes":{"series":"MTA-156","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-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":"644615","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"4","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":"$0.6500","priceTiers":[{"qty":1,"price":"$0.65000","currency":"USD"},{"qty":10,"price":"$0.56500","currency":"USD"},{"qty":100,"price":"$0.46540","currency":"USD"},{"qty":500,"price":"$0.40466","currency":"USD"},{"qty":1000,"price":"$0.33385","currency":"USD"},{"qty":5000,"price":"$0.29338","currency":"USD"},{"qty":10000,"price":"$0.27315","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9b4da764a6d42a72a88cf1ca34a5921a.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-644615-4/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 3-644615-4?","answer":"The 3-644615-4 mates with MTA-156 series receptacle housings that accept the corresponding crimp contacts.
