What is the usable shelf life of the through-hole version of part number UC3865N that went obsolete a few years ago? The "N" suffix indicates PDIP package type. I tried to locate on the TI search engine, but it was not found:

Only the SOIC version "UC3865DW" was found, but I am not sure if the same shelf life information would apply since the package types are different. Any guidelines about usable shelf life would be appreciated.
