Can also use phe 13005.The ST13005 is a NPN 400V 4A TO-220
The STX13005 is a NPN 400V 3A TO92
The STT13005 is a NPN 400V 2A SOT-32
KSE13005-2 means that we are getting 2amps at output.You could compare The Vceo, Ic, PD as following:
KSE13005,TO-220
VCEO Collector-Emitter Voltage : 400V/4A/75W

florescent emergence light circuit. in that circuit two transistor of kse13005-2 is used.What kind of circuit do you want to use KSE13005 or 2Amax?
Does 2Amax using very often or just want to keep it for some special Load?
If 2Amax using in a general purpose circuit, maybe you can use 2N3055, and plus Heatsink.
2N3055 datasheet:

i Do not measure the current because i purchased it from the market. after that due to high and low voltage it is damage and i did not open it. Now i open it and want to repair it so it can work again.Did you measure the total current consumption of the emergency light circuit? (2A max or less)
In the real application circuit, the 4A component used in a 2A max current consumption is not appropriate, at least have to provide 3 times or more of 2A, it means the 2A max circuit load need a component which can provide a 6A max or more.
Like as 2N3055 had 15A max rating, almost used it about 2~3A max in the circuit, some people maybe use it about 5A max, but it need bigger heatsink.
Consider your original size and heat problem, if you can use Mje3055 is better than the other 4A Power components.
Mje3055 and Mje2955 datasheet, TO220 60V/10A.

Thanks dave. i am listening to himListen to ScottWang...
You can fix it now and fix it again later when it does the same thing.... Or you can fix it using his suggestion and never have to fix it again...
..
Your choice...

I do not understand the difference between the two transistor, Especially the E13005-2. I could not Found the datasheet of E13005-2 either.If the old one E13005-2 didn't add the heatsink, then you can add a small heatsink for the new one PHE13005, it will give you a little help for the temperature of PHE13005.
