Here's the old parts and the new box...
As you can see, the old controller is BMW # 1221
7788327 and as
Clavurion already mentioned, the new Beru controller is a GSE102. I assume the old one is also a GSE102 but it is not labelled as such.
If you have a probe camera you may be able to read the numbers on your one in-situ. Or if you have younger eyes than mine!
