replacement for 175 WIV high speed diode

I could get lucky and be one diode away from a great deal on a TFM-35. Of course the diode is not one I am familiar with and not enough info for me to cross reference. It is D233 , a 175 WIV high Speed .4 diode.
Cursory google search for "175 wiv diode" gives me nothing.
Searching through Mouser and Digikey, trying to whittle down the 30,000 choices I have, I can't seem to come up with a combo of 175 WIV and .4 amps? Though I could easily be misinterpreting that .4 in the parts list.
Surely someone has had to replace one of these diodes as there are 14 in the unit, so anyone happen to know what diode was used to replace this?
Actually pretty excited and hopeful the only problem was the diode gave it up and is the cause, not a symptom.

Would a 1N459 happen to ring any bells ?

I am taking for granted that that one will be appropriate then. I am only going to order 30,000 of them tho - if I do not get it right by then, I am sending it to Bob

Re: replacement for 175 WIV high speed diode

actually I went with a 1N5617
only ordered 20,000

update - on a whim, I emailed Rita's shop and asked them what diode they used as the replacement for this. First, is amzing they take the time to answer questions like this, but even more surprising to me, Rita says she uses the 1N4004 diode there.
I thought it had to be much faster then that, I was looking in the 4ns range, the 1N4004 is in the 2 microsecond range.
But if that is what they use, that is what is going in it.
Even on the far out chance I get this working, will still replace my own caps, but by the end of the year I am still going to send it off to them. Worth $175.00 just to know they looked at it and of course Bob's autograph is priceless
