The G4 and E4 suffixes were added for ROHS conversion. The
G4 and E4 parts are exactly the same as the original parts
without the G4 or E4 suffix.
For lead-frame-based devices, the RoHS-compliant solution
is backward-compatible with lead-based processes; so the
same part is shipped regardless of whether a unique part
number or a standard part number is ordered.
Lead-frame-based unique part numbers will consist of the
standard part number plus a two-character suffix (usually
E4 or G4, sometimes E3, E6, G3 or G6).
"E" = RoHS-compliant
"G" = Green (RoHS-compliant and no Br/Sb)
