The 3.96mm pitch is wider than the common 0.100\" headers, so the board footprint and the mating receptacle must match this spacing exactly — a 0.100\" receptacle won't fit. In practice, the 3.96mm pitch and tin-plated contacts typically support 5-7A per circuit with 18-20 AWG wire. Voltage rating is 600VAC, which covers line-voltage control circuits and machinery power distribution. ## Housing and flammability rating The insulator is natural-colored, glass-filled thermoplastic rated UL94 V-0. The header is shrouded on one wall, which provides some keying and prevents the mating plug from being inserted backwards.","metaTitle":"TE Connectivity 644752-8 MTA-156 Header, 8 Pos, 3.96mm Pitch","metaDescription":"TE Connectivity 644752-8 MTA-156 vertical header, 8 positions, 0.156\" (3.96mm) pitch, tin-plated contacts, friction lock, UL94 V-0.","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":"-","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":"0.425\\\" (10.80mm)","Ingress Protection":"-","Base Product Number":"644752","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"8","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":"0.700\\\" (17.78mm)","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":"$0.6900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.69000","currency":"USD"},{"qty":10,"price":"$0.66300","currency":"USD"},{"qty":100,"price":"$0.53470","currency":"USD"},{"qty":500,"price":"$0.47342","currency":"USD"},{"qty":1000,"price":"$0.41493","currency":"USD"},{"qty":5000,"price":"$0.36202","currency":"USD"},{"qty":10000,"price":"$0.34465","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of the 644752-8?","answer":"The pitch is 0.156\" (3.96mm).
