Not sure how much this will help, but my dad has a Samsung Mythic and I noticed it had the same charger except his didn't separate so you could hook it up to the computer (It's a once piece wall charger) and it worked great on my phone to charge it when I forgot my charger at home. So my guess is they are probably interchangeable, but maybe someone with more info will chime in.
I found this list of phones that use the same charger/Micro USB port
