Since it is so hard to get the SJ2-35464A-SMT-TR socket this mesaages are very helpful, but I would really appreciate more information. I cannot see clearly how to wire it propertley.
I got this from your messages, but I don´t know how to connect plug detect, or if it is not possible to use this conector and I would need search for five or six pins socket.
Connect the 'TIP' to either 'L signal' pad and 'SLEEVE' to either 'ground' pad. This will connect the microphone but the AudioMoth won't know that it is there. To tell the AudioMoth that an external microphone is present make a direct connection between the 'jack detect' pad and either of the two 'ground' pads.
Please, could someone confirm if this alternative connection will work before I make a mess? ;)
If onboard mens mic is going to be disabled permanetly maybe it is better to bypass the connector and make the external mic conection directly to the board. What do you think?
Note that while the pins don't match, if you're willing to get a bit creative you can make any TSSR jack work - you just need to solder three wires from the Tip, Ring 2, and sleeve pins on the jack to one of the L signal, plug detect and ground pads respectively on the board and you should be good to go. I did this with a TRRS breakout board from Amazon, a number of resellers have them (sparkfun, adafruit), glued the breakout board to the side of the battery case, fastened down the wires and it works a treat.
Thanks Seth! In the end I got a colleague to help and he did exactly that, though he glued it to the top surface rather than the side. A good solution and works fine :-)

@Alex Rogers Thank you so much! So, it would be something like that?
In this case, could I use also the mens mic this way when not external mic connected or it would be disbaled permanetly?

It looks like your one has a different footprint to the SJ2-35464A-SMT-TR you may not be able to solder it onto the board.
The mapping of pins to contacts on the plug also seems to be different so these ones won't work I'm afraid.
Thanks Alex for your helpful reply!
