3.2 Wedgelock Compatibility: Ensuring Proper Secondary Locking

A robust connection isn’t just about the housing; it’s about securing the terminals. Automotive connector interchangeability extends to the wedgelocks (TPA – Terminal Position Assurance) as well. You can legally and physically install an Amphenol wedgelock into a Deutsch housing and vice versa without compromising retention force.

The naming logic for wedgelocks follows the same “Add an A” rule:

  • Deutsch P/N: Starts with W (e.g., W2S for a 2-way socket wedge).
  • Amphenol P/N: Starts with AW (e.g., AW2S for a 2-way socket wedge).

Quick Wedgelock Reference:

  • 2-Way Socket Wedge: W2S ➔ AW2S
  • 4-Way Pin Wedge: W4P ➔ AW4P
  • 12-Way Socket Wedge: W12S ➔ AW12S

By utilizing these direct equivalents, we help you maintain your production line’s momentum while significantly lowering your Bill of Materials (BOM) costs.
