It mounts through-hole right-angle with solder termination and carries a friction lock that holds the mated housing in place — you should hear it click when the latch seats. ## Pitch, footprint, and lock alignment At 0.156\" (3.96mm) pitch, the single-row layout leaves room for routing between pads on a standard 2-layer board. The 1-wall shroud guides the mating receptacle, and the friction lock prevents the pair from backing out under light vibration — if it backs out, it's scrap, so the lock is worth confirming before the harness ships.","metaTitle":"TE Connectivity 4-644754-3 Header, MTA-156, 13 Pos, 3.96mm","metaDescription":"TE Connectivity AMP Connectors 4-644754-3 MTA-156 header, 13 positions, 0.156\" (3.96mm) pitch, 600VAC, tin-plated contacts, through-hole right-angle, friction","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-156","Package":"Bulk","Features":"-","Shrouding":"Shrouded - 1 Wall","Termination":"Solder","Applications":"General Purpose, Industrial","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":"0.156\\\" (3.96mm)","Product Status":"Active","Voltage Rating":"600VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.300\\\" (7.62mm)","Ingress Protection":"-","Base Product Number":"644754","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"13","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.175\\\" (4.45mm)","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":"0.400\\\" (10.16mm)","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":"$2.9191","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/17ead6985f507040427337e85710dcd3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/4-644754-3/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does TE Connectivity AMP Connectors provide for 4-644754-3?","answer":"The header carries a UL94 V-0 flammability rating on the glass-filled thermoplastic housing.
