Chosen Solution

Controller model: CUH-ZCT2E.

  1. Would FJDS -040 work if my current/existing board is JDS -040? I can mostly found FJDS-040 which seems to be different compared to my JDS-040. My USB charging port:

FJDS I keep finding on ebay etc.

As you can see board layout is little bit different. Would those FJDS one work? 2) On USB boards I see square with number 1 or 2 (on different board), since both are JDS-040 boards, what those means? In short, can I replace JDS-040 board ignoring those numbers. Example:

The FJDS-040 is also known as JDS-040 or JDS040 and should be compatible for as long main board controller is a JDM-040 which it will since your original is a JDS-040.

Looks like it is! According to this guide on iFixit though. DualShock 4 CHU-ZCT2U Charging Port Replacement
