Thank you all for the replies on and off the reflector. The side by side data
sheet was good, although much of it is greek to me.
Seems like the PNA is more common in the kits I've seen, and slightly
more robust judging from the comments and the data sheets, but then the PN
is
I don't think you need worry at 12 volts supply, either will work. The A
suffix is just graded out to stand higher voltages than the .

What's the difference between a PN and a PNA transistor? When used as
a switch, can a PN be used as a substitute for the PNA? Thanks.

This will give you the story - They are slightly different

Looking at the A suffix , it appears they are graded units having a
higher breakdown voltage across the elements. It should work anywhere a
without suffix is specified.
The PN should work in PN A circuits that do not exceed its element
voltage ratings, which if you are
My understanding is the A is the military spec version. Maybe I'm
wrong, but it's got to be something like that, either that or a
slightly later version.. you might try googling a bit, spec
sheets for common parts can be pretty easy to find, I'm always
looking up the simple stuff
