Briggs voltage regulator question

[JimS 1]

I have a 16LTH with a Briggs engine that has a bad 691185 voltage regulator. This part number is also a substitute for regulator 394890. My question is can I go the other way and use the 394890 part to replace the 691185? Does anyone know what the difference is between the two? Thanks.

The 691185 Should Be the Same As The 394890 The 394890 Has Been Superseded To The 691185 # And Cost Around 70.00 List
