1032013 can be used as replacement, but each situation needs to be checked before shipping. If this is a newer machine (M&R s/n) we can send this & the schematics for the machine along with two PC55 to mount the new unit. If the machine is older ( No M&R s/n) we can just send the unit without the schematics and the customer would have to contact service for help with install. The thing is that the old and new are both the same and they do the same thing, but the new one wires a little different than the original. T1 port on the old one may be T2 on the new one, as an example.
