I used these sticks to replace broken analogs on a PS3 controller (the controller revision was the ‘asuka’ model, which also has orange potentiometers). However, the L3/R3 buttons were bigger on the purchased sticks (the broken analogs had a smaller button). Thus it was not a perfect fit and I had to modify the sticks to install them properly.
After that was done the stick worked very well (good response, no drifting etc).
So would definitely recommend!
