So at work I have a coworker that came to me looking to have me repair a broken component on a circuit board. I think he said it was an audio jack. However, it doesn’t look like a regular audio jack, so I’m not sure what the heck it is and thus don’t even know what part I need to order to do the replacement swap repair. I’ve attached two pictures I took of it and in the picture from the top of the circuit board, I’ve circled the component, and in the picture from the bottom of the circuit board, I’ve circled the solder joints.
I threw it to ChatGPT a few moments ago, and it said the following:
The damaged part is almost certainly a PJ-320A-style 3.5 mm audio jack:
- 3.5 mm female socket
- Right-angle/horizontal entry
- Through-hole mounting
- Four electrical terminals
- Central plastic locating post
- Approximately 14.1 × 5 × 6 mm
The four soldered pads surround the smaller central hole, which is mechanical rather than electrical. The exposed curved metal pieces in the broken housing are the jack’s plug contacts.
The closest identification is:
- Manufacturer family: generic PJ-320A
- Likely replacement: SHOU HAN PJ-320A-4P DIP
- LCSC number: C18185602
- PJ-320A-4P product listing
Unfortunately, I couldn’t find the actual PJ-320A footprint stocked by DigiKey or Mouser. Their four-contact 3.5 mm jacks generally use different footprints. For example, DigiKey’s STX-3500-4NTR is surface-mount and therefore won’t fit this board.
Any ideas?
