Expert Reply:

12k trailer brake assemblies like the part # 23-442-443 and 15 assemblies like part # 23-446-447 can both be 12-1/4 inch by 5 inch and use the same 7 bolt mounting pattern so dimensionally it's hard to say. I would look for part numbers on your assemblies to see if you can determine it that way or you could look on the axle for a capacity listed.

The big difference between the two will be magnet sensitivity as the higher rated assemblies will need a magnet that grabs a little harder. Going with a higher rated than needed magnet/assembly doesn't give you more braking power though and instead would just make it harder to find sweet spot for brake controller gain setting.
