Korg Poly800/EX800 Users

Good morning every advise about this problem its very apprecieted.

I have to replace an ALPS component to the pitch bender-joystick of a Korg Poly 800 mk2. Its written on it ALPS 607p 10kb and it has 4 pins soldered on the board. I have doubt that i can find the component itself but do you think that i can replace it with a brand new one? Are there components that surely suit? Or do you think that i have to find a replace joystick with the board itself? Or is it possible to put an other joystic (but i dont like to modify the synth).

Thank you so much for the attention. Here some pictures of the component.
