This unshrouded header accepts the MTA-156 receptacle housing (e.g., 640441-5 for 5 positions) with the appropriate crimp socket contacts. The square male pins (0.045\" square typical for MTA-156) provide reliable contact retention in the receptacle. ## How this header compares to a shrouded sibling Compared to the 1-1871673-2 (a 4-position, 2-row, shrouded header with board lock and detent lock), the 644749-5 is unshrouded, single-row, and lacks polarization features. Choose the 644749-5 for lower-cost, single-row power/signal connections where mis-mating protection is not critical.","metaTitle":"644749-5 TE Connectivity MTA-156 Header, 5 Pos, 3.96mm Pitch","metaDescription":"644749-5 TE Connectivity AMP Connectors MTA-156 unshrouded header, 5 positions, 0.156\" (3.96mm) pitch, through hole, tin-plated, 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":"Unshrouded","Termination":"Solder","Applications":"General Purpose, Industrial","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"-","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":"0.125\\\" (3.18mm)","Ingress Protection":"-","Base Product Number":"644749","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"5","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":"$0.8400","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.84000","currency":"USD"},{"qty":10,"price":"$0.71300","currency":"USD"},{"qty":100,"price":"$0.63990","currency":"USD"},{"qty":500,"price":"$0.52358","currency":"USD"},{"qty":1000,"price":"$0.46541","currency":"USD"},{"qty":5000,"price":"$0.40723","currency":"USD"},{"qty":10000,"price":"$0.38687","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/3c2d8f658937b01151bbfaadff4e3d99.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/644749-5","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/644749-5 when reusing this data.
