A closed end stops the IDC slot from over-traveling off the cable, and the polarizing key forces correct pin-one orientation every press. ## Termination and Wire Compatibility It accepts both discrete wires and ribbon cable, but the wire gauge is fixed at 22 AWG; the IDC slot dimensions are sized for that conductor diameter. For ribbon cable, the 0.156\" pitch must match the ribbon conductor spacing exactly — a 0.156\" ribbon centers each conductor over its IDC slot. A 0.100\" ribbon at this pitch would bite between conductors and scrap the assembly. When fully seated, the ramp snaps over the header latch, providing positive retention that resists vibration better than a plain friction fit. The polarizing key on the closed end prevents reverse mating — the header's keyway must align, or the connector won't seat. For field service, the ramp releases with a flat-blade screwdriver prying it outward, allowing the receptacle to be unmated without damaging the contacts. It is ROHS3 compliant. No official cross-reference or second-source replacement is listed by TE, so the BOM line should reference this exact TE order code.","metaTitle":"TE MTA-156 5-643819-0, 20 Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 5-643819-0 receptacle, 20 positions, 0.156\" pitch, IDC termination for 22 AWG discrete or ribbon cable.","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":"Red","Pitch":"0.156\\\" (3.96mm)","Series":"MTA-156","Package":"Bulk","Features":"Closed End, Polarizing Key","Wire Type":"Discrete or Ribbon Cable","Wire Gauge":"22 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":"643819","Number of Positions":"20","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1000","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.10000","currency":"USD"},{"qty":10,"price":"$1.87100","currency":"USD"},{"qty":25,"price":"$1.86200","currency":"USD"},{"qty":50,"price":"$1.84300","currency":"USD"},{"qty":100,"price":"$1.69100","currency":"USD"},{"qty":250,"price":"$1.68148","currency":"USD"},{"qty":500,"price":"$1.52948","currency":"USD"},{"qty":1000,"price":"$1.36798","currency":"USD"},{"qty":2500,"price":"$1.26348","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8d21922fe22cbe5ad072668c50c3d523.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/5-643819-0","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/5-643819-0 when reusing this data.
