Hi Tim,
I think I get where you are comming from a little better.
I Digi-Key parts.
Put in MOSFET and you'll find 3,216 items.
Then a search engine that you select from categories.
Amps, package, type, voltage...
That way, you can select one item and get bunches of hits.
select another and a more narrow selection.
Once you are down to 2-5 pages of matches, (lower left) 'view pages'
to see what is in stock and what is not.
The idea is that this search method will narrow down a segment of
what is on the market (what digi-key offers) but a range of parts in
that segment.
Once you are narrow to some couple hundred matches, you can refine
one step at a time and see the hits.
a 100V PNP MOSFET has one match.
PNP has 572 matches.
Then just keep trying one thing and broswe back.
Sometimes you'll find a 15A, 200V device is half the cost of a 50v 5A
device, in the same package.

What you suggest is basically what I do now when looking for
components. That process does get the job done, and maybe it's that I'm
just more lazy than I thought, but I still find couple of hundred matches
quite intimidating and a lot of work to go through and I usually end up
feeling like I most likely missed the best component match for the job. I
realize that I have to work hard to find parts needed, especially when the
pace in which new parts are developed and released is so fast, I just asked
the question in hopes that the pros here in our group had some
time/aggravation saving techniques to make the process smoother and easier.
