I have found one of the most useful single sources for general
information on semiconductors to be the ECG Semiconductors Master
Replacement Guide, about $6 from your local Philips distributor.
STK, NTE, and others have similar manuals. The ECG manual will
enable you to look up U.S., foreign, and manufacturer 'house' numbers
and identify device type, pinout, and other information. Note that
I am not necessarily recommending using ECG (or other generic) replacements
if the original replacements are (1) readily available and (2) reasonably
priced. However, the cross reference can save countless hours searching
through databooks or contacting the manufacturers. Even if you have
a wall of databooks, this source is invaluable. A couple of caveats:
(1) ECG crosses have been known to be incorrect - the specifications
of the ECG replacement part were inferior to the original. (2) Don't
assume that the specifications provided for the ECG part are identical
to the original - they may be better in some ways. Thus, using the ECG
to determine the specifications of the parts in your junk bin can be risky.
