I am guessing it is a 2SD1913 NPN transistor.
The 2 means two junctions and the S means silicon, it is very common to leave this suffix off of transistor markings as it is pretty much implied.
A, B, C, and D are frequency response characteristics.
Always try putting a "2S" in front of three legged devices that start with the letters A, B, C, or D.
So chances are no you can not just replace it with a 7805.
