Anyone can call their stuff "space grade", but it is only marketing copy if it isn't flight qualified. I don't track new stuff because my interest is in hardware developed in the 80s and 90s, but for that time frame there are long lists of qualified parts and published testing methodologies. I know that for military grade stuff of that time you had a combination of distinguishing characteristics that set one part number apart from the commercial grade offering: top bin draw and complete performance characterization. At some point that was relaxed to where it is now just mostly about binning and traceability.
