Is there a pin-compatible replacement for RC-01W9102FT?

No pin-compatible (0201 package) replacements were found that satisfy the engineering requirement for a 1.5x power rating safety margin. All same-package candidates had an insufficient power rating.

What risks should I check before replacing RC-01W9102FT?

The primary risk is physical incompatibility. Alternatives like RS-03K9102FT use a larger 0603 package, requiring a new PCB layout. Using a part without an adequate power rating risks overheating and failure.
