    Hi Elsa,

    Historically, G4 and E4 suffixes meant that the devices were rated to be "Green" or "Lead Free." However, as time has passed, all devices have been pushed to these new "Green" or "Lead Free" standards, but the part numbers have remained available so that customers have had a consistent orderable part number. There is no difference between the G4 and none-G4 version of the devices.

    Regards,
