Difference between A06B-6055-H106 and A06B-6055-H108?

[birdman3131]

Ok I have a machine with an A06B-6055-H106 spindle drive that seems bad. We have another parts machine that has a A06B-6055-H108 drive. Visually and connectors they seem identical. Is there a meaningful difference between these 2 drives or should I be ok just swapping them? The control board on the front runs the same part number so if need be Ill just try swapping that but I figured i would swap everything if possible.

Exactly same one, only software for motor (eproms) and parameters .

Ok update time. The 108 has larger screws holding the wires on. Luckily I finally found the actual issue and got the original drive working. (Checked about 20 fuses but missed seeing 2. those of course were the ones that blew.)
