If I had to replace that part, would look on Mouser or Digi-key or other distributor parts catalog for 33 uF 600 V FILM capacitors and simply install 3 of them in series. (with appropriate balancing resistors)
Interesting that putting your PN into search engine returns only this thread - is the PN correct? Maybe the Z is actually a 2 ?

Thank you kindly for your response.
I thought it interesting too that this site was the only one returned.
Not sure that Digi-key or similar is the way to go.
We're looking at about 20 in parallel capable of handling a 4,000A, 100us pulse with a repetition frequency of up to 400Hz.
And they are spares for the no longer available ABB part so would also need to be physically compatible.
ABB claim that they no longer have the datasheets but I'm sure it's out there. Somewhere over the rainbow........
Why can't you just confirm with the manufacturer of your product to use substitutes in addition to looking for the datasheet?

I suspect he does not just do that because the manufacturer simply did not suggest a replacement or offer any help.

You suspect correctly which is precisely why I put out my request for help.

Since you are trying to match an existing unit, could you post a picture and dimensions? That might ping the memory of someone who knows a supplier of equivalent capacitors.
