ST25RU3993 Engineering Sample (ES)

[JimC]

How to screening ST25RU3993 for Engineering Sample (ES) in our factory's incoming inspection and where is the ES marking located on its case?

Currently in a stop production due to this issue.

Hi JimC,

For this parts, ST is selling fully tested mass products only.

Engineering samples are not available nor distributed anymore.

Engineering samples would have an additional marking line saying "ES".
