The TE Connectivity AMPMODU MTE 103958-8 is a 9-position, single-row IDC receptacle designed for discrete or ribbon cable.
The closed-end feature means the housing has a solid back wall, so the IDC slot is fully enclosed; this prevents wire stubs from protruding past the contact area.
The 103958-8 mates with any AMPMODU MTE unshrouded header of the same 9-position count and 0.100" pitch — typically the 103956-series or 103935-series headers from TE. No stripping or crimping is required for the wire termination, but the connector housing itself is free-hanging (in-line), so it is not board-mounted — it terminates the cable end, and the header sits on the PCB.
