Can a resistor that has 5% tolerance be used in place of one that was originally 10% tolerance if all the other values are the same as the original?
The original was a 1/4 watt 2.2 ohm +/- 10% ( Red, Red, Gold, Silver). I ordered one from an electronics supplier, and when it came in, it was a 1/4 watt 2.2ohm +/- 5% (Red, Red, Gold, Gold). They told me it was actually better than my original because its tolerance would not allow it to fluctuate more than 5%, where my original allowed 10%. My thinking is that the resistor does not determine the amount of fluctuation in the voltage of the circuit, but must be able to tolerate whatever fluctuation may exist, up to +/- 10%. That being said, a resistor with +/- 5% tolerance would not replace my original because if the fluctuation exceeds 5%, it would possibly heat up and become a fuse at some point. Am I right or wrong? Thanks !!
