They are the same derailer, but you are going to need a new BB unless you have one with spacers that you can remove to use it.

Sheldon Brown said:
"E-type " Shimano units have a bracket that is held on by the bottom bracket retaining ring. These also use a special braze on to stabilize the derailer.

E-type mounts do not permit any adjustment at all, so you generally need to use exactly the size chainrings that your E-type front derailer was designed for.
