It mates with MTA-156 IDC or crimp receptacles to connect discrete wires or ribbon cable to a PCB. The unshrouded design means no side walls — visual alignment during mating is easy, but the mating half provides the retention, not the header itself. At 3.96 mm pitch, the 8-position header occupies about 31.7 mm of board edge — enough room for 18 AWG wire without the contact-to-contact crowding you get on 2.00 mm pitch headers like the 1-292164-1 from the CT series. Tin-plated mating contacts are cost-effective for applications with fewer than 25 mating cycles. If the connector sees quarterly field-service disconnect, the tin surface will wear; for higher cycle life, a gold-plated sibling in the MTA-156 family is a better fit. The 600 VAC rating is a full voltage class above the 125 VAC of the CT series header (1-292164-1), making the 640385-8 suitable for line-voltage signal and power distribution in industrial equipment. ROHS3 compliant. Mates with any MTA-156 receptacle housing (IDC or crimp style). The unshrouded header has no polarization keying — pin-one alignment depends on the receptacle's housing key or wire color code. Termination is solder to through-hole. The 0.125-inch (3.18 mm) post length provides enough stand-off for wave-solder cleaning. No locking or retention features on the header itself — the mating half's latch or TPA provides the vibration resistance. For high-vibration environments, specify a shrouded header with a detent lock (like the 1-292164-1) instead.","metaTitle":"640385-8 TE Connectivity MTA-156 Header, 8 Pos, 3.96 mm","metaDescription":"640385-8 TE Connectivity AMP MTA-156 unshrouded header, 8 positions, 3.96 mm pitch, right-angle through-hole, tin contacts, UL94 V-0, 600 VAC.","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, Right Angle","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":"640385","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"8","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":"0.390\\\" (9.91mm)","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":"$1.0100","priceTiers":[{"qty":1,"price":"$1.01000","currency":"USD"},{"qty":10,"price":"$0.96100","currency":"USD"},{"qty":100,"price":"$0.79200","currency":"USD"},{"qty":500,"price":"$0.72002","currency":"USD"},{"qty":1000,"price":"$0.62261","currency":"USD"},{"qty":5000,"price":"$0.53366","currency":"USD"},{"qty":10000,"price":"$0.52419","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/4ff1c5c4a57a4dbf68a26f034d4504c5.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/640385-8/alternatives.json"},"ai":{"faq":[{"question":"How does 640385-8 compare to a shrouded header like 1-292164-1?","answer":"The 640385-8 is unshrouded — no side walls, no polarization key, and no latch.
