The housing carries 15 pin positions but only 12 are loaded with contacts. That leaves three empty cavities – a deliberate pin-out skip for keying or future circuit expansion. Confirm your wire harness uses exactly those 12 loaded positions before committing the BOM. ## Right-angle orientation and board-edge routing The 0.300\" (7.62 mm) insulation height clears most through-hole components on the opposite side. ## Friction lock vs. secondary retention If your application sees continuous shock or cable tug, consider a header with a positive latch or TPA. ## Voltage and current – reading the fine print Rated 600 VAC – that covers 480 VAC motor circuits, panel distribution, and most industrial AC supplies with headroom. For a 20 AWG wire in the MTA-156 system, expect around 5 A per contact at a 30 °C rise. ## How this compares to the 1-292164-1 alternative The 1-292164-1 is a CT series header at 0.079\" (2.00 mm) pitch, 11 positions all loaded, with a shrouded 4-wall housing and detent lock – a denser, fully populated alternative for lower-voltage (125 VAC) signal duty. The 644958-1 carries higher voltage (600 VAC) and a wider pitch for heavier wire, but leaves three cavities empty.","metaTitle":"644958-1 TE Connectivity MTA-156 Header, 15 Pos","metaDescription":"644958-1 TE Connectivity AMP Connectors MTA-156 header, 15 positions (12 loaded), 0.156\" (3.96 mm) pitch, through-hole right angle, tin contacts, friction","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":"-","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":"644958","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"15","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"-","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":"12","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2900","priceTiers":[{"qty":1,"price":"$5.29000","currency":"USD"},{"qty":10,"price":"$4.63200","currency":"USD"},{"qty":100,"price":"$4.14660","currency":"USD"},{"qty":500,"price":"$3.85566","currency":"USD"},{"qty":1000,"price":"$3.44341","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/644958-1/alternatives.json"},"ai":{"faq":[{"question":"Does the 644958-1 have all 15 positions populated?","answer":"No – the housing has 15 positions but only 12 are loaded with contacts.
