What I've found is that you can use darn near anything in the way of a piezo. When I go to Radio Slacker, I try to find A/C piezos rather than D/C ones. The D/C ones seem to be the ones that have the little circuit board.
As Andy says' they would work OK, . . . but in my experienceL; once you remove the circuit board you are left with no lead wires and you're going to have to solder directly onto the disc. . . . . . (My ham-handed soldering makes this difficult.)
With the D/C circuit board ones - there are also 3 leads instead of 2 - and I'm always scratching my head over which ones to use.
Give me the A/C piezos and those little 2" lead wires and I'm in hog heaven, By the way, I just electrified my washtub bass last night with one of these and it worked out awesome! I hot glued a chunk of mattress-type foam rubber inside the washtub near the string hole and sealed the piezo in the middle of that. No feed back issues or handling noise to speak of whatsoever, and the bass response seems surprisingly good!

Back when Radio Shack actually carried radio stuff, and had employees who could spell radio....they would carry "items of local interest". Which basically means they would vary the inventory for things that people used alot of. Try asking them to stock extra ones for you or....get pi$$ed off like the rest of us and start ordering them.
You can the other ones, but you need to remove the circuit board (that you pay extra for). I have also used ones from "personal alarms" that I found a dollar store- even cheaper than the Radio Shack buzzers!
