The closed-end housing prevents wire insertion from the wrong side, which saves a rework step on the assembly line. The locking ramp holds the mated pair against vibration in a harness, typical for internal appliance wiring or control panel cable runs. ## IDC Termination and Wire Gauge This receptacle terminates 24 AWG wire via IDC — the insulation is displaced as the contact is pressed into the housing, so no stripping or crimping is needed. The tin contact finish at 80.0µin (2.03µm) is thick enough for moderate-cycle harness assembly; it will tolerate a few insertion/removal cycles without fretting, but the mating half should also be tin-plated to avoid galvanic mismatch. ## Mating and Locking Mates with the standard MTA-100 header (unshrouded, 0.100\" pitch, same position count). The locking ramp on the receptacle engages the header latch for positive retention — the pair will not separate under cable tug or moderate vibration. No secondary lock or TPA is required; the ramp is the primary retention. For a right-angle cable exit, the receptacle can be mounted at the board edge with the header oriented to match.","metaTitle":"TE MTA-100 4-643814-3, 13 Pos IDC Receptacle, 0.100\" Pitch","metaDescription":"TE Connectivity MTA-100 4-643814-3 receptacle, 13 positions, 0.100\" pitch, IDC termination for 24 AWG wire, tin contacts, locking ramp, active production.","metaKeywords":null},"attributes":{"series":"MTA-100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Circular Connectors","Panel-Mount & In-Line Circular"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"White","Pitch":"0.100\\\" (2.54mm)","Series":"MTA-100","Package":"Bulk","Features":"Closed End","Wire Type":"Discrete or Ribbon Cable","Wire Gauge":"24 AWG","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line), Right Angle","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":"643814","Number of Positions":"13","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6800","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.68000","currency":"USD"},{"qty":10,"price":"$1.53200","currency":"USD"},{"qty":25,"price":"$1.48680","currency":"USD"},{"qty":50,"price":"$1.47160","currency":"USD"},{"qty":100,"price":"$1.36600","currency":"USD"},{"qty":250,"price":"$1.34340","currency":"USD"},{"qty":500,"price":"$1.22264","currency":"USD"},{"qty":1000,"price":"$1.09433","currency":"USD"},{"qty":2500,"price":"$1.01132","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/578ebe1dfc4db0e9c77800055eb7d9d2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What header mates with 4-643814-3 MTA-100 receptacle?","answer":"The locking ramp on the receptacle engages the header latch for retention."},{"question":"What wire gauge does 4-643814-3 accept?","answer":"The 4-643814-3 is designed for 24 AWG discrete or ribbon cable, terminated via IDC — no stripping or crimping required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/4-643814-3","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/4-643814-3 when reusing this data.
