The orange housing colour is a visual key for the MTA-156 series, helping identify the pitch at a glance on the harness bench. The feed-through feature allows the IDC termination to pass the wire through the connector body, enabling daisy-chain wiring in multi-drop harness layouts without a separate splice. ## Tin Contact Finish and IDC Termination Tin is the correct choice here: the IDC connection cold-welds the wire into the slot, and the thick tin provides corrosion resistance at the wire interface. This is not a high-mating-cycle design; the tin contact is rated for the few insertion/removal cycles typical of harness assembly and field service, not repeated disconnect-reconnect duty. The IDC termination accepts 18 AWG wire — a single wire gauge, not a range — so the harness builder must confirm the wire size matches exactly. The connector accepts both discrete wire and ribbon cable, giving flexibility in cable construction for the same receptacle part number. ## Mating and Compatibility with MTA-156 Headers This receptacle mates with any MTA-156 header of the same 0.156\" (3.96mm) pitch and matching position count — 8 positions. No keying or polarisation feature beyond the standard MTA-156 shroud — the header's shroud is asymmetrical, preventing 180° mis-mating.","metaTitle":"TE MTA-156 3-640599-8 Receptacle, 8 Pos, IDC, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 receptacle, 8 positions, IDC termination for 18 AWG discrete or ribbon cable. 0.156\" (3.96mm) pitch, tin contacts, locking ramp.","metaKeywords":null},"attributes":{"series":"MTA-156","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Circular Connectors","Panel-Mount & In-Line Circular"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Orange","Pitch":"0.156\\\" (3.96mm)","Series":"MTA-156","Package":"Bulk","Features":"Feed Through","Wire Type":"Discrete or Ribbon Cable","Wire Gauge":"18 AWG","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle","Contact Finish":"Tin","Fastening Type":"Locking Ramp","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Cable Termination":"IDC","Base Product Number":"640599","Number of Positions":"8","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.99000","currency":"USD"},{"qty":10,"price":"$0.94600","currency":"USD"},{"qty":25,"price":"$0.90440","currency":"USD"},{"qty":50,"price":"$0.89180","currency":"USD"},{"qty":100,"price":"$0.77930","currency":"USD"},{"qty":250,"price":"$0.75016","currency":"USD"},{"qty":500,"price":"$0.70848","currency":"USD"},{"qty":1000,"price":"$0.61263","currency":"USD"},{"qty":2500,"price":"$0.56679","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is 3-640599-8 compatible with MTA-156 headers?","answer":"Yes, this receptacle mates with any MTA-156 header of the same 0.156\" (3.96mm) pitch and 8-position count.
