Does anyone know something I could use in place of the Bourns 2262 Trimpot? I can't seem to find it anywhere
I think you mean the 3362 :)

No reason you can't use any trimpot that fits the footprint of the board. I know the inexpensive 6mm trimpots from Tayda will work if you bend the legs ever-so-slightly.
Thanks !
