The orange housing carries a closed end and a polarizing key, so it only mates with a keyed header in the correct orientation; the closed end also blocks an over-length header from seating fully, preventing a partial mate. ## IDC Termination — Wire Gauge and Cable Type The IDC slot is sized for 18 AWG wire — not a range, a single gauge. The termination accepts either discrete wires or ribbon cable, which makes this receptacle a common choice for harnesses that transition from a ribbon cable to discrete leads at the board edge.","metaTitle":"TE MTA-156 5-643817-0, 20-Position IDC Receptacle","metaDescription":"TE Connectivity MTA-156 receptacle, 20 positions, IDC termination for 18 AWG wire, 0.156\" pitch, tin-plated contacts, locking ramp.","metaKeywords":null},"attributes":{"series":"MTA-156","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 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":"Closed End, Polarizing Key","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":"643817","Number of Positions":"20","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6300","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.63000","currency":"USD"},{"qty":10,"price":"$2.34800","currency":"USD"},{"qty":25,"price":"$2.33560","currency":"USD"},{"qty":50,"price":"$2.31180","currency":"USD"},{"qty":100,"price":"$2.12110","currency":"USD"},{"qty":250,"price":"$2.10920","currency":"USD"},{"qty":500,"price":"$1.91854","currency":"USD"},{"qty":1000,"price":"$1.71596","currency":"USD"},{"qty":2500,"price":"$1.58488","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/3e098e2ebd88d07b79c6f0f6a7b8bbc9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 5-643817-0 compatible with MTA-156 headers?","answer":"Yes.
