The TE 5-103948-2 is a 3-position IDC plug from the AMPMODU MTE series, designed for mass-termination to 26-30 AWG ribbon cable. It uses a 0.100" (2.54mm) pitch, which matches standard ribbon cable spacing and aligns with common 0.100" header footprints.
This plug terminates ribbon cable via IDC (Insulation Displacement Contact) — no stripping or soldering required. The 26-30 AWG range covers the typical wire gauges used in flat ribbon cable assemblies for internal signal interconnects.
This is a signal connector, not a power interconnect; the narrow IDC termination and 0.100" pitch limit per-contact current to the sub-3 A range typical of the AMPMODU MTE series.
The closed-end feature on this plug prevents the cable from pushing through the housing during termination.
No official replacement or cross-reference part is on record; the 5-103948-2 is the current production order code for this 3-position AMPMODU MTE IDC plug.
