you could try to find both models on and see if they share part numbers. Although a cursory glance seems like you’ll need to be more specific, as to type 1, type 4, etc.

I can direct you to the site that will have the definitive answer. The Dewalt RAS forum is on an antiquated platform called Delphi, but those guys know more about the Dewalt saws than anyone I’ve seen. When you speak of Dewalt motor interchangeability it’s important to include the “frame size”, which is on the motor label. Of course, someone here may know as well.
