There is no direct substitute link I am aware of.

In general , if you are looking to sub any transistor, you should look for something close or higher in breakdown, package/ voltages/toff/ton/etc. there is no "magic" list. It can be very critical depending on the circuit design &/or what the application is. need to know the original specification and compare to what you actually have available,

Sometimes you may not have any other choice?

As an example, can use this page as a reference to find a possible sub.

Another forum posting suggested the following on a similiar request;

"Possible substitutes for FJAF6812 include 2SC4890, 2SC5411, BU4525AX, and NTE2365 with an insulator."
