TE AMPMODU MTE 4-Position IDC Plug — 0.100" Pitch, Gold-Plated Pins
The TE Connectivity 5-103946-3 is a 4-position AMPMODU MTE plug that mass-terminates to 22-26 AWG ribbon cable via IDC contacts — no stripping, no crimping per wire. The 0.100" (2.54mm) pitch matches standard protoboard and legacy ribbon cable grids, so the footprint is predictable on any board layout. Gold plating at 30.0µin (0.76µm) on the male pins handles repeated mating cycles and resists corrosion in low-level signal paths. The black housing is closed-end, meaning the contacts are fully shrouded on the mating face — no exposed pins to snag during handling.
Position Count vs Siblings — 4 vs 2, 6, 8
The 5-103946-3 carries 4 positions — a middle count between the 2-position 5-103946-1 and the 6-position 5-103946-5, all at the same 0.100" pitch with identical gold plating and IDC termination. If your BOM calls for exactly 4 circuits, this is the direct fit; the 6-position sibling adds two unused positions that waste board space and the 2-position leaves you short. No other spec differs — same closed-end black housing, same 22-26 AWG range, same active lifecycle status.
