Fake ST SGS Thomson Part (GS-R405S)

[andybarrett1]

Looking for a little help.

We have purchased some GS-R405S from a reputable seller here in UK.

I have the feeling with have both been duped by his seller.

(1) There is a label with the makers details on the top of the device ... Not screen printed !
(2) The tolerances are miles out for the pin spacing etc. Over 3mm
(3)  A couple have bounced back on me now as well as a fail on the bench
(4) Have seen china sellers on ebay selling same batch / date code on ebay again on the label

Just looking to see what others think 

Thank you for reading

You know that´s an obsolete part so as supplies are getting low...

The problem is also that´s it´s potted... not going to be easy removing all that...

But it might be parts that were indeed marketed for the Chinese market and are just reappearing, try to save non-function-critical costs isn´t that crazy,
especially if they try to sell in a competitive market.

About the tolerances, are you absolutely sure it´s the same variant? It could be the same part but not the same variant.

Try to de-pot the failed one! The devil is in the details, meanwhile contact your seller, things like that happen all the time.
