If you have datasheets of these transistors as well as the circuits using them, so you can easily know which transistors can be used to replace.
Sometimes it is hard to find out this kind of cross table, on the other hand, they usually show 1 or 2 equivalent transistors only, and in many cases, you cannot find out those equivalent in your market.
So, try to research the datasheets, the circuits (voltage, current, frequency, ... used), local market, and you can find out what you want.
When I began to learn electronics, I tried to collect that kind of document either, and then I quickly found out that they are really useless.
