Transistor ekvivalents

[*Star Project]

Hi!

Lacking a book of replacement semiconductors
i need someones help to find replacement for
these transistors:
2SC 2021(R)
2SA 937(Q)
2SC 945(P)
2SA 733(P)
2SC 1583
2SC 2291
2SB 64-
2SD 667C
2SK 30(Y)
By the way. Are they pin compatible. Since I'm using
a PCB layout made for thoose japanese transistors
I need to know if the replacement ones are pin 
compatible.
Thanks in advance
