You think of suitable numbers and then check them in the cross-reference.

I started doing that back in 1974 with an HEP replacement guide, and it was
a good way of getting a basic idea of what a device was.  Saved having to
check multiple books just to see whether a transistor was NPN or PNP.  The
cross-reference section in the NTE guide is far larger than that old HEP
guide, and of course it's now faster when you can do the look up
electronically.
