The Problem
The TP-105 (U-384/U) plug is 0.14 inches longer than the standard TP-101 (U-174/U) plug due to its 5th conductor for dual-channel/stereo audio. This extra length prevents proper seating in PTT jacks designed for the shorter TP-101, causing intermittent connections, poor audio, or complete signal loss.
Headsets that use TP-105 plugs include Peltor COMTAC XPI (dual-comm), stereo aviation headsets, and other dual-channel tactical headsets with separate left/right audio channels.
