The shelf life of SMD is above 5 years for moisture sensitivity level (MSL) 3. However, the shelf life might be limitless for MSL 2 and MSL 1. Electrolytic capacitors can expire. Once the dielectric compound dries out, it kills the capacitance. Sometimes, the expiration condition of ...
Not to say there is not a place for component shelf life, but it should be up to the OEM. Tod Cummins Director of Corporate Quality Assurance Delta Group Electronics Inc. Tod has been working in the Aerospace Electronics Industry for 25 years, beginning with 4+ years working for PCB ...

Most electronics (under 60 yrs old) do not just go bad sitting around, with the exception of electrolytic capacitors. That is unless they are stored, or otherwise in high humidity or harsh conditions where corrosion (and molds grow) can form and cause corrosion. Heck, I've come across old...
Depending on the mechanism and its category, physics of failure model and acceptance criteria can be selected for shelf life estimation. This approach is demonstrated with electrolyte evaporation in electrolytic capacitors and moisture diffusion induced delamination in plastic encapsulated components....
