when I looked a few years ago I couldn't find a modern version that would fit inside the motor. I had to fit one outside, and made a cover for it. The only small ones I can see now are rated at 100 V DC or less, so not useable on mains power even in the USA. I can't see another three lead version for mains use, even though I got one within the last ten years. It is the type of safety critical component that gets ever tougher specifications as time passes.
