Resistor use?

I am wondering if it makes any difference using a carbon resistor or a metal film resistor.
Put another way. Plan calls for 330 OHM carbon resistor, I have 330 metal film resistors. Will it make any difference?

I happen to be working with PIC microcontrollers.

Thanks.

Metal films are more stable over time/temperature than carbon. If you are just using is as a pullup, or a current limiting resistor, then you will never notice a carbon's bad behavior. If you are making a voltage divider, you might notice it.

As I see it ....Its like and upgrade for resistors using metal film.
Yes. In just about any application, a metal film resistor is an upgrade from a carbon composition. And since there is not a great price differential between them, you don't see many carbon comp resistors used anymore.
