Reference ADS421 long-term stability

Hello,

I am studying ADR421 datasheet and thinking if different package (MSOP and SOIC) IC will have the same long-term stability (50 ppm/1000 hours).

On ADR421 datasheet, is "Long-term stability: 50 ppm/1000 hours" guaranteed for both MSOP and SOIC?

I'd appreciate you reply. Thank you.
