Kept candidates are active.
Can it be replaced directly?
No direct pin-compatible replacement is proven from the provided fields.
Best replacement path
Start with RS8552XK, then verify SOIC-8 pinout and loop stability.
Main risk
Pinout is missing and faster or slower GBW can change circuit behavior.
