The 0.100\" (2.54 mm) pitch matches the standard MTA-100 header footprint, making this a direct mate for the male pin headers in the same series. The blue closed-end housing with a locking ramp provides positive retention — the ramp engages the header latch and gives an audible click when fully seated, which matters in harness or field-service applications where vibration can back out an unlamped connector. ## 9 Positions at 0.100\" Pitch — Fit and Footprint The 9-position count is the BOM line match — confirm your circuit count before committing. The 0.100\" pitch is the standard MTA-100 spacing, so the receptacle footprint is identical to any other 9-position MTA-100 header. The single-row layout keeps the connector narrow, fitting into tight board-edge locations. The closed-end design means the housing blocks the last cavity — no wire can be inserted into position 9, which is a deliberate keying feature to prevent mis-mating with a 10-position header. ## IDC Termination — How It Connects This is an IDC (Insulation Displacement Connector) receptacle — the 26 AWG wire is pressed into the contact slot, where the sharp tines pierce the insulation and grip the conductor. No stripping, no crimping, no soldering. The free-hanging, right-angle mounting orientation means the cable exits at 90° to the connector axis, which is useful for routing along a board edge or inside a shallow enclosure. The tin-plated contacts carry 80.0 µ\" (2.03 µm) of tin — a heavy plating that handles the wiping action of IDC termination and provides corrosion resistance in indoor environments. ## Mating — Works with MTA-100 Headers This receptacle mates with any standard MTA-100 male pin header of the same 9-position count and 0.100\" pitch. The locking ramp on the receptacle engages the latch on the header — look for the mating header with a locking ramp or detent feature. The closed-end design prevents mating with a 10-position header, which is intentional keying. For ribbon cable applications, the IDC termination accepts standard 0.100\" pitch ribbon cable — the 26 AWG wire gauge is specified for the contact slot.","metaTitle":"TE MTA-100 3-643815-9 Receptacle, 9 Pos, IDC, Tin","metaDescription":"TE Connectivity MTA-100 3-643815-9 IDC receptacle, 9 positions, 0.100\" pitch, tin 80.0µ\" plating, locking ramp, blue closed-end housing.","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":"Blue","Pitch":"0.100\\\" (2.54mm)","Series":"MTA-100","Package":"Bulk","Features":"Closed End","Wire Type":"Discrete or Ribbon Cable","Wire Gauge":"26 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":"643815","Number of Positions":"9","Contact Finish Thickness":"80.0µin (2.03µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5100","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.51000","currency":"USD"},{"qty":10,"price":"$1.38400","currency":"USD"},{"qty":25,"price":"$1.34280","currency":"USD"},{"qty":50,"price":"$1.32920","currency":"USD"},{"qty":100,"price":"$1.23380","currency":"USD"},{"qty":250,"price":"$1.21340","currency":"USD"},{"qty":500,"price":"$1.10432","currency":"USD"},{"qty":1000,"price":"$0.98843","currency":"USD"},{"qty":2500,"price":"$0.91345","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9476b525b8c21512605aec3c6c95366f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 3-643815-9?","answer":"The 3-643815-9 is sourced to order through independent distribution against an RFQ.
