Quoted from hlaj78:Many of the components in the remakes that have been done so far have been changed although the rules and layout have remained the same.
You can listen to the KP seminar on Twitch where they address the Capcom parts vs other parts.
Previous remakes - assuming you mean MMR and AFMR. Only difference is the boards and lights. All mechanical parts are the same as used in the original games. Though brand new, the parts are made to Williams specs.
