Can I use a regulator/rectifier from a different model on my Yager 200i?

These models have this updated cooling fins.
I run in hot enviros.

The R/R electrics is just the black box and the rest of the part is just a cooling sink.
My R/R (D406/31600-LDG7-900) looks exactly like the old one in the pic.

Obviously the cooling sink design was updated. These models are newer than my Yager.
Is there really any variation differences with these 3 pole R/R designs???

Are there really any differences or does Kymco just like to use unique part # per model.
I was told the last part (900) is just the supplier.
The first part 31600 is used for all their R/R from what I see.
It's the middle (LDG7 vs KED9) that is different.

Does Kymco use a part # naming gaming OR are there truly differences?

Thanks!

Does it test the same electrically? Pin for pin? Same connector? Same mounting pattern? Getting answers to these questions may be a little tough but that's a start. You may have to stick your head in the noose to find out. But, hey! You would be a hero to this gang if you find that it is an exact replacement!

I'm finding that various parts for my Sector, are much or are the same as a Honda CG125, which is quite good news. Takes some research though. Also have a couple of similar things on my 1999 bike as a 2004 different model, brake caliper being one.
Unfortunately, this does NOT make me a hero on here, as nobody else has the rare piece I have, so I am no help!

Sometimes, I go on Racingplanet.com. The US version is the same as UK site. Pick you're scooter, then choose OEM parts. There, it shows all parts in graphics with part numbers within each part group. If the part matches, all good. I have looked at other bike models, for parts and have matched a few bits.
Not sure that this is of help to you, as you may seeking the specification of a part and the fact the part list below the graphics is in German, makes it harder!
