The official V3.0 BOM says use Digikey 399-3584-ND.
12V for stepper is an optional 12V source for the stepper chip on the MS2 daughterboard.

*This post contains ignorant, yet well meaning questions*
A track environment is understandably tough on mechanical components.
But, is the failure of an ECM on the track a mere coincidence, or does the failure have something to do with sustained high rpm and the very rapid "cycling" of the capacitors to keep up with the injector and coil drivers?

Tantalum capacitor applications need careful evaluation because the temperature, voltage, and ripple current stresses can cause failures. In this application it might be on the order of 0.1 - 1 % per 1000 hours.
Polymer aluminum electrolytic capacitors are less "delicate". I suggest using these:

The only time I've seen these blow personally is:
1. ran a flyback to s12c instead of s12.
2. installed the MS in a NB and they blew instantly; this happened twice.
otherwise, I've never had one blew from sustained use.
