My customer checked XRAY for LM393PWRG3.
The lead frame was different depending on the device.
Are these certified leadframes?

The top photo markings and lead frame shape are consistent with the "G4" plating version LM393PWRG4.

The different plating materials use different lead frames, which accounts for the difference. Electrically, they are identical.
Please note that with some high volume devices such as this, if they ordered the LM393PWR, they will receive either the "G3" or "G4" plating depending on what is available. This would account for why they are getting two different versions from the same orderable.
