Any similar shaped audio jack should work, either 3 pin or 5 pin is fine to use. Either of these can be considered an official part (I've used a few different ones over the years based on what's available at the time, these are the last 2 models I've used):

That's actually still the current version of the RaspberryJAMMA. The only difference between your older board and the current ones is I now use 2.5A fuses to accomodate Pi4 - if you upgrade your fuse your board is completely up to date (earliest boards used 1A, later I moved to 2A for Pi3, now 2.5A - the silkscreen still says 1A as I haven't updated it). In case you want to order the 2.5A current fuse at the same time it's this one: https://au.element14.com/littelfuse/025 ... st=1207779

Would this be suitable to replace the fuse on my old board, the one linked only ships from the US £15 postage! :

That fuse is way too high of an Amp rating, find a 2A or 2.5A max.

Can the fuse be soldered anyway or should there a positive and negative?
