Yes. Though some applications are consolidated so not all the same as Wix, Napa Gold, or even the ProSelect applications. Example, the popular 7317/14610 application is called the ST9688 because it combines the 9688/3593a application size with the 7317 application, at the size of the latter.
And very similar to the O'R MicroGard (same stated efficiency) line too, but also the ST line combines more applications than the MG.
