Intel486™ Processors

I have two Intel486™ Processors with the exact same part number (A80486DX4WB100) but the S-spec numbers are different (SX158 and SX209). Are these the exact same parts?
The S-spec number denotes an internal specification number that Intel uses to track stepping, testing changes, and a number of manufacturing and test variables.
