Replacement thumbstick base(mechanical/electronic part) for Playstation/Psone (DualShock / Analog Controller), Playstation 2 (DualShock 2), Xbox, Xbox360.
The only PS1 or PS2 controller I can think of, which it couldn't be used for, is the oldest PS1 controllers(which didn't have thumbsticks)

XBOX & XBOX360:
All information I can find states that the Xbox & Xbox360 use identical parts for analog sticks as PS1 & PS2, so should work perfectly. They definitely look the same as those in an Xbox controller.

PS3:
Might fit some PS3 controllers, but probably not likely, as PS3 controllers seem to use smaller parts than PS1,PS2 controllers.
I've been told these don't fit in the Sixaxis controllers(PS3 controllers without rumble), it seems likely it also won't fit DualShock 3 controllers.

Use these to replace worn or broken thumbstick base.

As you will need to unsolder the old part, & solder this in it's place - this is only recommended for those who have used a soldering iron before.

This is only the base part(as in picture), not the top part(sold seperately).

Might also fit some non-Sony brand controllers, but only if they use identical thumbstick parts to Sony controllers of course.
