Can it be replaced directly?
No confirmed pin-compatible replacement is supported by the provided candidates.
Best replacement path
Use a 12MHz 3225 passive crystal matching 20pF CL, ESR, tolerance, and stability.
Main risk
Active CMOS oscillators need power and output routing, unlike the target crystal.
