Electrical – How does the physical size of resistors effect replacement of them

resistors

To expand on my question.I need to replace a 5 band 100k resistor and possibly others but the resistors that I have in my stock of parts for replacements are physically larger than the ones on the current PCB project.
Can I use these as replacements?
How does the physical size of resistors factor in, or does the size even factor into these components?
Further details to describe resistor.The main body colour of both resistors are blue.

For DC and even up to high-frequency AC, the issues are typically only mechanical, not electrical.

However, for very high-frequency AC (VHF or UHF radio frequencies), there may be other factors to consider like bulk capacitance and lead inductance, etc.

So this question/answer doesn't hold up across the entire spectrum. Since we don't know the nature of the circuit, be aware that this is not a 100% universal answer.
