Counterfeit Semiconductors

Counterfeit Semiconductors

Counterfeit Semiconductors

(OP)
Hello,
I recently purchased some Toshiba power transistors
from a supplier. I noticed they looked a bit odd compared to the originals. I am aware that there is a problem with counterfeit semiconductors so I have decided to seek some opinions about these before I attempt installation. The links below show the photos I have taken of them. So the question is do the new devices appear to be genuine or counterfeit?
Thanks.

The original devices.

The new devices.
These are the replacements.

RE: Counterfeit Semiconductors

Boy.. That will be a problem for anyone to tell you other than the manufacturer.  I would contact Toshiba or a Toshiba rep and provide these links to them.  They are generally more than happy to help because counterfits cause them great harm in several ways.
