Regulator/Rectifier part numbers

[NewfieVaradero]

Hi,

Having a few issues with my Reg/Rec on my 2008 XL1000VA (Canadian edition if that matters). I see alot of upgrade options for Mosfet for the older model part # 31600-MBT-D21. Honda Canada has part # 31600-MBT-D51 as the correct part number for by bike. Does anyone know if they're interchangeable? Not alot of knowledge over this side of the pond on the old girl and don't want to order another Honda unit if I don't have to. Thanks

If you do a yahoo or google search with both part numbers you will find plenty of adds for replacements  Giving both parts No's

for example  :

or

Which suggests that they are completely interchangeable

Thanks, Just in case anyone else is looking at this post in the future I heard back from Honda today and the D51 is a Mosfet unit, the D21 is SCR so they are interchangeable but D51 is by far the better unit.
