Yes. Under the revisions (effective 7/1/18), RDC and mRDC images will be electronic checks, and may be reconverted to become substitute checks. They will be subject to subpart C and, as substitute checks, subpart D of Reg CC (but, alas, as Randy points out, not subpart B yet). So you can refer to the potential for the collection or return of a check truncated via RDC/mRDC as an electronic check or electronic return check or as substitute checks. I assume you want to point out that if you do a chargeback, you may provide a substitute check to the depositor.
