Part for changing out a composite output on the Visual Cortex

Hey, i have a visual cortex used at the school i work on. Some random student tried using a 3,5 mm patch cable on the composite out and broke off the tip. I tried various extraction atempts, but have now realized that i need to change the RCA connector. I have built 30+ cadet and castle modules and feel confident that i can replace it without destroying anything
But searching around at mouser i do not see any parts that looks like the ones used, can you provide a part number at mouser for me? I have an order at mouser coming up in a few days, and would like to include this part. Thank you!
Best. Lau! IMG_9132|375x500

I (successfully!) replaced one of the RCA connectors on a War of the Ants that I own - and I want to wish you the best of luck! (What I assume is) lead-free solder is no joke! I am definitely not a DIY novice either, have desoldering specific tools, and I found it to be quite a 3D challenge. I gave up and removed a jack to have more room to work. The solder really wanted to stay put in the through-holes.
If I were to suggest anything, I think a little hot air will speed up things quite a bit (if you are comfortable with using it).

This stuff and good quality copper braid are your pals!

That’s certainly what I used for my repair.
I still found it harder to work with than good ol’ Leaded Kester 331.

Yeah, leaded solder is always much easier to work with. Part of it with those RCA jacks is that the whole jack shield acts like a big heat sink; next time try a big, chunky tip on your iron to increase its ability to take the thermal load. (I’m of course making assumptions here.) Lead free solder has a higher melting point, so the thermal load is also high due to that.

Thanks all. Hadnt thought about the non-leaded solder situation, guess i will get my electronics technician friend to help out here, im using his workshop anyway.
And thanks to Lars for the parts link!
