Yes, I know that the C3686 has an internal clamping diode, while the C3688 does not.

BUT -

I have seen the K7400/K7500/U2000/U5000 chassis' with a C3688 installed instead of the C3686. The K7500 Service Manual even has the C3688 in the parts listing, although the schematic is too blurry to be sure.

I need to replace a blown C3686 on a K7400, and have a working C3688. I was thinking about trying it...
