Surface Mount Resistors

[Mermprin]

Can you use Thick Film Surface Mount resistors in 5% and 1% tolerances in place of the Carbon Film and Metal film thru hole?

Yes, but beware of impulse properties and voltage rating, maybe not a problem in your case. SMD resistors can't handle so high voltage and can't handle short pulses very well.

how does their inability to handle short pulses manifest itself?

Mermprin was talking about carbon and metal FILM resistors, not carbon composite resistors. If you look at the datasheets standard SMD resistors can safely handle 5x the nominal rating for short pulses. Depends also on temperature of the element.

In general, yes you can replace them but look at http://www.vishay.com/ for datasheets if you want to be sure Mermprin.
