Shimano Acera RD-M3020-SGS Rear Derailleur - 7/8 Speed, Long Cage, Black

Q: Will this replace stx rc?

Yes it will as long as your low sprocket on your cassette is as least a 30t. There are cheaper Shimano derailleurs that will also work. What makes this one special is it can be used on a 1x setup with a 11-40T cassette.

Q: Will this replace an sis megarange?

A highly qualified "Yes". Be prepared to become a self-taught expert in bicycle derailleurs in the process. Expect to discover that you need other parts, such as a hanger-adapter. You will almost certainly need to replace your shifter cable and housing, as the cable entry is different, necessitating rerouting, and hence a different length cable and housing.
