Threats to external validity pertain to the generalization of findings to populations outside the sample. Conducting the same experiment at another time or in another place are threats to external validity. Using different subjects is also a threat to external validity because the results may not be applicable to the larger population. However, changing the operationalization of the independent variable affects internal validity - the extent to which we can conclude that the independent variable caused the observed effect on the dependent variable - rather than external validity.
