Motor replacement: can't find 2-speed version, can I use 3-speed?

I need to replace the motor on this cheap turntable, but can't find the exact model (EG-530SD-2F). I do find a lot of listings for the EG-503SD-3F model.

Are these interchangeable? Would it simply not use the 78rpm speed if I out a 3F variant in here, or would it not work at all?
