Hi,

I made some kind of Ethernet relay board. I designed the board to use RJ-45 connector with integrated magnetics.
The board is designed for 212A-11XA0-R-B-2 connector, but I couldn't find it later, so I bought this connector:
https://www.farnell.com/datasheets/17297.pdf

Here is the datasheet of the connector for which the board is designed:
View attachment 212A-11XA0-R_B_2.pdf

I am confused with the internal magnetics of these connectors, they look different.
Are those conectors interchangeable?

Thanks!
 

The PCB pinouts are different, so you cannot just swap them.

It's a pain not having a standard PCB pinout for these - I've had the same issue and had to modify the PCB with a drill and literally wire the connector in.

Thanks FoxyRick!

I agree with you, it's a pain. I thought that there is a standard for these connectors.
Now Ihave to throw away the board or the connectors...
