Like a surface mount 100 K resistor replaced by a 1/4 watt resistor. It is equivalent by elementary electronics but is it in practice ? The same question for capacitors.

As long as you can mount them and they make electrical connections yes. Just be careful especially with the caps. If the surface mount is a silver mica, make sure the other one is also. Different kinds of caps behave differently at different frequencies.

I don't have handy heat dissapation stats on a 1/4 vs 100k ohm, but keep that in mind depending on the proximity of other components.
Other than that, when I have replaced SM components, I usually leave the leads fairly long and put a 1/16" inch bend at the end of the lead to be able to solder it onto the board. I use shrink tube to insulate the "legs" on the component to avoid contact with other components. This doesn't always work so well when there is RF wafting around, as the long leads can pick up stray rf and screw up sensitive circuits.
