David Clark 09227P-42 M642/4-3 OEM Electrical Connector — PJ-055 Style Earphone Plug

The David Clark 09227P-42 is a genuine OEM electrical connector manufactured to MIL-spec M642/4-3 — the standard ¼-inch (6.35mm) earphone plug used across a wide range of David Clark aviation headsets and compatible general aviation communication systems. This is the larger of the two standard dual-plug GA connector types, carrying the audio signal to the ear cups, and is the same plug commonly referenced as the PJ-055 in general aviation applications.

When a headset connector is damaged, corroded, or simply worn out from years of line service, replacing it with a genuine David Clark OEM part is the right call. Aftermarket substitutes introduce variables in signal integrity and fit that an OEM connector eliminates. The 09227P-42 restores your headset to factory spec at a fraction of the cost of headset replacement — and for any technician or pilot with basic soldering skills, it's a straightforward field repair.

This connector is confirmed as a parts list item for the David Clark H5020 headset, and its M642/4-3 MIL-spec designation ensures broad compatibility with any cockpit audio panel or intercom system wired to the standard dual-plug GA configuration. Country of origin is the United States.

Keep one on the shelf. For any operation running David Clark headsets, this is a low-cost consumable that prevents a worn plug from grounding a crew member on a busy day.
