I'd just not mention it and assume it was fine. After all all
the pcbs have to be the same whether repaired or new, if the
circuit was dangerous then the device would be dangerous no
matter what pcb was in it.

ISTR Geoff, who owns a company which repairs such things, saying
that over a period of time you get to know what things fail on a
particular make, but is not allowed to improve the design by using
uprated parts. It has to be repaired like for like.

Who did he claim wouldn’t allow that ? No one gets to not allow that.

In order to get Gas Council (not sure if its still called this)
approval you have to submit a technical file of the boiler concerned.

Any change would invalidate that certification.

I just don’t believe that Geoff ever had to do anything of the sort.

The UK and EU have rules that replacement parts are of the same
specification for certain items including car parts etc.

That has nothing to do with the replacement of electronic components
on a PCB that have a higher temperature rating than what was originally
there which had a lower temperature rating.

Sourcing a component is everything. You're obviously not aware of
components with fake marking or that are substandard.

Perhaps you're getting mixed up with other countries that are less
discerning?

You're confusing car parts with electronic components.

You're confusing electronics with safety critical components.
