Hi
I have a small B500 rectifier that seems to have given up the ghost. I know its a B500 as its printed on it!
While looking for a replacement I'm finding quite a few offerings.
This component seems to be used on a 110v machine saw to generate DC voltage in order to pull in a solenoid switch effectively.
What is the specification for a B500 rectifier that makes it different from other similar components and how very specific does a unit need to be within its function?
 
It should have more writing on it to indicate the voltage and current. As you have found there are numerous bridge rectifiers with that number. I doubt there is anything special about it in this application.
If you can find something with the same physical format and adequate current rating then go with the highest voltage rating you can find. If it is driving a solenoid you might get quite high inductive voltage spikes as it switches on and off.

More info needed. You say the component "Seems to be used" are you not sure? If certain then anything with with a voltage rating greater than 110 (220/440/1000) should be OK, voltage wise. What you need to know is, what is the current rating of the solenoid . Anything above that should be OK, won't hurt to double it! If you have a spares list for the machine it may give you an indication to some or all of the above. As stated in previous post the rectifier should be marked.
Edit. Any rectifier that meets the above and will fit in the space will be OK . Doesn't have to be B500.
