RJ45 connector replacement

Wed Jul 17, 2019 6:06 pm

Hello
I own raspberry pi3b +. However, the other day I realized that I could not connect to the Internet.
The RJ45 pin was broken.
Since I have a soldering iron, I would like to replace the RJ45 modular.
But I do not know which parts to buy.
Thank you very much

Removing a multi-pin through hole component from a multi-layer board is not a simple procedure. If you are truly convinced it must be replaced I recommend dismembering the socket in place to the state where individual pins can be desoldered and removed. You may find a Dremel type tool helpful in the dismembering stage.

There is a part number on the partial schematic https://www.raspberrypi.org/documentati ... educed.pdf

Isn't this just soldered on the board?
Also, should I use parts A70-112-331-N126?
Thank you

From those two questions I conclude that the probability of you successfully replacing the socket is vanishingly small. :(

all right
This pi is used without Ethernet.
Thank you for answering the question

I think the problem would be heating all the pins at once to remove the connector. Dismantling the connector so the pins can be unsoldered individually is a solution.
