The following table shows comparison of the MR-J2S series and MR-J4 series dimensions. The height and
width of the MR-J4 series are the same or smaller than the MR-J2S series basically. The depth will increase
when a heat sink is placed in a cabinet. For the mounting dimensions, the mounting screw pitch and screw
sizes will be changed. (Refer to the comparison of dimensions.)
