The base product number 644613 covers both variants. The difference is the suffix: -3 indicates a 3-position version; -2 would be a 2-position version. Same pitch, orientation, finish, and locking — only position count changes.","metaTitle":"3-644613-3 TE Connectivity MTA-156 Header 3-Pin 3.96mm","metaDescription":"3-644613-3 TE Connectivity AMP Connectors MTA-156 header, 3 positions, 0.156\" pitch, right-angle through-hole, friction lock, tin plating, UL94 V-0.","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":"644613","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"3","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":"-","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":"$1.3000","priceTiers":[{"qty":1,"price":"$1.30000","currency":"USD"},{"qty":10,"price":"$1.22000","currency":"USD"},{"qty":100,"price":"$1.04970","currency":"USD"},{"qty":500,"price":"$0.92484","currency":"USD"},{"qty":1000,"price":"$0.82839","currency":"USD"},{"qty":5000,"price":"$0.74895","currency":"USD"},{"qty":10000,"price":"$0.70221","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-644613-3/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of 3-644613-3?","answer":"The mating pitch is 0.156\" (3.96mm), standard for the MTA-156 series."},{"question":"Is 3-644613-3 compatible with standard MTA-156 connectors?","answer":"Yes — it mates with any MTA-156 receptacle housing that accepts 3-position headers.
