How to determine which used inverter will work in my 2007 Prius

Check compatibility at car-part.com. Part search interchange is shown automatically.

Differentiation shows before April 2007, and from May 2007 date of vehicle manufacture. Check your ViN #

Is there a plate on the driver's door jamb that shows the manufacture date?

 

If the information in #2 is right and the split is up-through-April versus May-or-after, that seems to fall in the second bin.

 

Oh look at that... I remembered it wrong... Any vehicle made in May 2007 thru end of 2009 is compatible... I think I remembered date of manufacture of my own car, which is July. That's the beauty of memory though... You gotta work a little extra if you care about having your facts right!

Transmission interchange shows 2004-09 will work. Partial screen grab attached.

 

I would have no hesitation at all to use an inverter from a 2008 in my 2007. I would likely have no hesitation to use any 2004-2009 inverter if I needed to replace a failed one, as long as I knew it was functioning properly in the car it was salvaged from. Same for the transaxle.

Just like there are 6 different HV Battery ecu part numbers available between 2004-2009, any of them will work in any year Gen 2 HV battery.

 

G9200-47100 is the part number for the inverter used from 8/2003 through 12/2004.
G9200-47120 is the part number for the inverter used from 1/2005 through 4/2007
G9200-47121 is the part number for the inverter used from 5/2007 through 3/2009

Try to order a 47100 or 47120 from Toyota. Nope, not gonna happen (unless there's some NOS out there), because they've been replaced by the 47121. Actually, the 47100 got replaced by the 47120 in the first update, then the 47120 got updated to the 47121. So it really doesn't matter.
If you use a salvaged 2008, then you're installing the latest revision model. A model that has a different screw or something, yet is still the current replacement for all the earlier models.

Just like the 6 HV battery ecus from 20004-2009. The latest and greatest revision is the factory replacement for all earlier versions also, yet any of the earlier versions will also work if you happen to have one.

As for this...
I hope by the end of this thread we have a definitive answer what we can use.

I think we're there.

 

As a group we'd prefer you take the hit and try to install an inverter on the wrong side of the split year so we finally know if there's any actual compatibility issue and if there is what the symptoms are... Of course that might not work out for you too well, but we'd appreciate it. Lol!!!!

 

In my experience most claims of compatibility limitations within each generation of Prius are false. In this case it's Gen2 Prius 2004-2009 and in my experience everything I've tried that was in a 2004 works fine in a 2009. Of course it'd be a huge pain to find out there are exceptions, so I don't push my luck too much.
