There are some that are different, maybe the LED is reversed, or it may use
a darlington transistor. If you do not have the original parts, a used or
"standard" replacement would be worth trying but don't automatically assume
it is right. If it works and regulates, then I would say it is OK to use.

Subject: [TechAssist] Question about photocouplers
> Hello all,
> I received a set that had some surge damage and I did not have an exact
photocoupler in stock to see if the set would turn on.I took a photocoupler
from a junk chassis,(same manufacturer, but a completely different model)
and the set fired right up.
> My question is, are these photocouplers for televisions rated about the
same? I rarely find these bad in my shop. Will order original, but just
curious.
> Thanks for any insight.
