Looking for some replacements for components I can’t source

I am trying to repair a monitor of mine that is in an arcade game. There are a few components that I need to replace that I am having some trouble sourcing. I usually use Digikey or Mouser.

They are all diodes. The schematics have the following:
MUR460 (I found this one and it looks like I can use NUR460 for improved performance)
BYV28 (I found several choices such as BYV28-50 up to BYV28-600, not sure how to know what I need as the schematics do not give more information.)
BYV95C (can't find this one. found PR1505G listed as a replacement but can't find that either)

I am looking for parts in stock not something with a 10 week lead time. I am hoping there are parts that will work even though they may be more than I actually need. The goal is to keep the monitor running for years to come.

Thanks everyone!

You can get the MUR460 at Newark.com
The only difference between the different BYV28 parts is the PIV, so get the largest available (e.g. the BYV28-600)
Newark.com suggests BYT52J-TR as a replacement for BYV95C.

Thank you for the info about the BYV28. That helps a lot.

I can not find the BYT52J-TR in stock at Mouser, Digikey, or Newark and none of them sell them in small quantities. If they had them in stock but just sold large quantites I would try to get an engineering sample.

Try the BYT52M -- that's the same thing but with a 1000 PRV rather than a 600 PRV, and it's available at Newark (and maybe others, but I didn't check).

Otherwise, you need to search for an Avalanche Diode with the following criteria (or better):
Repetitive Reverse Voltage Max: 600V
Forward Current: 1.4A
Forward Voltage: 1.3V
Reverse Recovery Time: 200ns
Peak Forward Surge Current: 50A (tp = 10ms, half sine wave)

So in the interest of teaching you to fish, here is, basically, the method I used to locate the replacements that I suggested:

I Googled the part number. This is a good way to find a datasheet. For the BYV28, the datasheet told me that the 'dash number' that follows the BYV28 number, is the PRV. In most cases a higher PRV device will work just as well as a lower PRV device.

You mentioned that you had tried *Mouser* and *Digi-key*. I use those sources, too, but when I can't find what I need there, I check *Newark* (and in a few cases, I discovered that Newark has a lower price). *Avnet Electronics* is another possibility. There is also *Allied Electronics*, but I rarely find what I need, there. Also, there's *microchipDIRECT*.

Then, there are all the surplus houses, like:

* All Electronics
* Alltronics
* Electronic Goldmine
* MPJA
* HOSFELT Electronics
* Electronics Surplus


The Hobby houses, like:

* Jameco
* SparkFun
