At 0.156\" (3.96mm) pitch, the header occupies a compact footprint for a 4-position power/signal interconnect. ## Rated voltage, temperature, and flammability Rated 600VAC, this header can carry line-voltage power in equipment like industrial controls, not just low-voltage signals. This header mates with MTA-156 receptacle housings (e.g., 3-640440-4 for 4 positions) that accept the corresponding crimp contacts. The tin-plated posts are compatible with lead-free wave solder processes. RoHS3 compliant per directive 2015/863. No official second source or direct cross-reference is listed; the MTA-156 series is proprietary to TE Connectivity.","metaTitle":"3-644754-4 TE Connectivity MTA-156 Header 4 Pos 3.96mm","metaDescription":"3-644754-4 TE Connectivity AMP Connectors MTA-156 header, 4 positions, 0.156\" (3.96mm) pitch, right-angle through-hole, 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, 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":"4","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":"$1.1800","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.18000","currency":"USD"},{"qty":10,"price":"$1.10300","currency":"USD"},{"qty":100,"price":"$0.94930","currency":"USD"},{"qty":500,"price":"$0.83644","currency":"USD"},{"qty":1000,"price":"$0.74920","currency":"USD"},{"qty":5000,"price":"$0.67736","currency":"USD"},{"qty":10000,"price":"$0.63509","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of 3-644754-4?","answer":"The pitch is 0.156\" (3.96mm).
