The header is unshrouded, so the mating receptacle relies on its own housing key for alignment — there is no shroud wall to guide the plug. ## Tin-plated contacts — cost over cycle count Tin is the economical choice for a header that sees one or two mating cycles in its life — typical for a board-to-cable harness built once and shipped. The trade-off is that tin frets under vibration after about 25–50 cycles, so if the application requires repeated field disconnect, a gold-plated sibling in the MTA-156 family is the better call. ## Active production — no redesign trigger The product status is Active, meaning TE Connectivity continues to manufacture this part number. There is no end-of-life notice, no last-time buy clock, and no official successor to cross-reference. The base product number is 640385, so any future revision would carry a different dash number — but for now, this exact order code is the current build.","metaTitle":"2-640385-4 TE Connectivity MTA-156 Header, 24 Pos","metaDescription":"2-640385-4 TE Connectivity AMP Connectors MTA-156 unshrouded header, 24 circuits, 0.156\" pitch, right-angle through-hole, tin contacts, 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, 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":"24","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":"$2.2141","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/4ff1c5c4a57a4dbf68a26f034d4504c5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch and mounting style of 2-640385-4?","answer":"The pitch is 0.156\" (3.96 mm), single row, 24 positions loaded."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/2-640385-4","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/2-640385-4 when reusing this data.
