Quick verdict

RISKY

Both use a 3/4-16 thread.

Thread size is the first hard-fit check for any comparison of spin-on filters.
Gasket OD and gasket ID are the most important seal-related dimensions.
Height differences can matter for clearance even when thread and gasket fit appear close.
Bypass and anti-drainback differences may be important, depending on the application.
