Aporte original por: TheLastMillennial ,
You can find replacement parts on places like Digikey, Aliexpress, and likely even Adafruit or Sparkfun. You’ll have to find a port with the correct footprint of course. If your port is too mutilated to tell, here’s some photos I referred from: [http://www.datamath.org/Graphing/Images/TI-83PLUS_I-0799_PCB.jpg|top down view] and [http://parzivail.com/content/images/2018/08/DSC_0023.JPG|close up]. You’ll want a port that is 2.5mm and has 3 conductors and 3 contacts. I don’t have the dimensions of the original port, however with some quick research, I found [https://www.digikey.com/product-detail/en/cui-devices/SJ-2523-SMT-TR/CP-2523SJTR-ND/281300|this port] which looks like it should fit. The only issue is the back contact doesn’t line up with the contacts on the PCB. You can likely just solder a wire from the contact to the PCB however, if you look at some of the sites I provided above then you may be able to find a more suited part.
