    Yep, 1N5275B's are getting pretty pricey. The Z4KE140A will work but it's a bit bigger than the original (and can handle more power than the original).
    Full reel price looks pretty good.

    Quoted from Drewscruis:

    Figured I'd post a pic of the Z4KE140A installed on a driver board. No modifications were needed.

    Good to know.
    Trying to locate a case of them now.
    ...
    Case now on order.

    What are the markings on the cap?
    All film caps that I have seen have the voltage rating marked on them.

    Looking at the photo - the caps in the photo look to be about the same physical size as a Panasonic 0.01uF, 400V film cap (but rotated 90 degrees). Of course, that is just eyeballing it in the photo.
    Can't compare to a 630V cap - I don't have any in that capacitance/voltage range. Panasonic data sheet says the 630V cap would only be about 2mm longer - so that part could possibly be a 630V rated part.

    "2J" prefix = 630 volt rating
    "103" = 0.01uF
    "J" suffix = 5% tolerance.

    So cap is fine.
