Its 0.156\" (3.96mm) pitch mates with the corresponding MTA-156 IDC or crimp receptacle to form a board-to-cable/wire connection. The UL94 V-0 glass-filled thermoplastic housing provides flame retardance for equipment inside an enclosure. ## 19 Circuits — an Uncommon Count for Single-Row Headers Nineteen positions in a single row is a less common circuit count than 20 or 18. The 0.156\" pitch means the board footprint is 19 × 3.96 mm = 75.24 mm wide, plus the keep-out for the unshrouded pins.","metaTitle":"1-640383-9 TE MTA-156 Header, 19 Pos, 0.156\" Pitch, Tin","metaDescription":"1-640383-9 TE Connectivity MTA-156 unshrouded header, 19 circuits, 0.156\" (3.96mm) pitch, tin-plated contacts, through-hole solder, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"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":"640383","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"19","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":"0.650\\\" (16.51mm)","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":"$1.1914","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a2dbdce74d2f6c90353f26cf98431808.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1-640383-9/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of the 1-640383-9 header?","answer":"The 1-640383-9 has a 0.156\" (3.96mm) pitch between centres."},{"question":"What is the mating connector for 1-640383-9?","answer":"The 1-640383-9 mates with any MTA-156 receptacle housing, such as the TE 640441 series IDC or crimp type.
