IMHO an airbag module is something you do not want to 'swap' with a different number because there just isn't enough information to let just about anyone know for sure there isn't a difference in its internals (calibrated for a specific vehicle). Air bag deployments may be closely set to the interiors they are installed in (the bags and their related sensors/control).
I would ONLY look for and install one that has the exact number on yours (unless a documented trail of substituted parts are available). That's MY opinion, for what its worth.
