Does the replacement need to be the same package type, or do you just need a high power BJT? Certainly for a TO-3 case, 2N3055 is already one of the cheapest and most commonly available types.
What is the application? for some things like a high power switching application, MOSFETs can also sometimes be used.
The TIP3055 is in a TO-218 package and has a power dissipation of 90 W max. The 2N3055 is in a TO-3 package and has a power dissipation of 115 W max. So, you can use 2N3055 instead of TIP3055.
