Product details

3-Position IDC Receptacle for Discrete or Ribbon Cable

The TE MTA-100 643813-3 is a 3-position IDC receptacle designed for terminating discrete or ribbon cable in a single pass. The closed-end design prevents stubbing during cable insertion, and the red housing aids visual identification in a multi-wire harness. Wire gauge is specified for 22 AWG discrete or ribbon cable.

No official TE replacement order code is listed for this part.

The 0.100" pitch and 3-position single-row layout match a standard through-hole or vertical header. The IDC termination is designed for 22 AWG wire.

Frequently asked questions

What is the replacement for TE 643813-3?

For a direct drop-in, the surplus channel is the only sourcing option. If the BOM can tolerate a different series, a TE applications engineer would need to recommend a current-production alternative.

Does 643813-3 work with 22 AWG wire?

Yes, the 643813-3 is specified for 22 AWG discrete or ribbon cable. The IDC slot geometry is designed for that wire gauge; using a different size will not produce a reliable termination.
