Depends on the application.
Also, depends on the tolerance....
If original tolerance is 7.5 +/- 10% and if the 82 ohm one measures at 82 ohms
then it is within spec for the original application of the 7.5 +/- 10%.
Also note some applications care about inductance (in wire wound resistors) vs non inductance. If non inductance is required it will usually be specified on the parts list and/or schematic.
