Are vented trims and non-vented trim interchangable?

MHCXX(S or F) are used for 100 and 225 amp NQOD panels. MHCXXV(S or F) are ventilated and used for 400 and 600 amp NQOD panels. NCXX(S or F) are used for 125 and 250 amp NF panels. NCXXV(S or F) are used for 400 and 600 amp NF panels.
The vented trims have shorter door openings. If they are used in place of the non-vented trims, the vents will interfere with the deadfront of the panel. If non-vented trims are used in place of vented trims, the door will be too big and leave a gap at the top and the bottom of the door opening.
