nolink: You can use any turnouts you like with DC or DCC; the only difference is where insulated gaps are required, desirable or convenient.
Electrofrogs are the all-rail frogs. These normally require a gap beyond the frog (place where the rails cross) if there's any possibility of feeding electricity from that end e.g. in a loop of track.
Insulfrogs are the plastic frogs. These don't always actually require gaps, but sometimes it simplifies things if you do. They may or may not (depends on manufacturer and series) deaden the rail on the unselected line. You may have to read the instructions with the turnouts to see which you have. With DCC it won't matter unless you try to feed a whole layout from one place.
(Electrofrog and Insulfrog a Peco's terms, but we use them because they're handy and descriptive.)
Of course, a reverse loop or wye will require 4 insulating gaps in any system.
