Hi, based on the picture attached, it´s possible to anyone to tell me if this is a counterfeit part? ''SITA'' or ''SITB''.

Cause:We have in stock a lot of this parts, and in some boards we don´t have any problems, and on other boards some parts burn.Is to control a 1000W resistive load.There is a specific mail, to enter in contact with ST to report this issue?Thank´s in advance.Best regards.

Hi,

I suggest you to open an online support request indicating the tracking code of the two devices. You should also ask support to your supplier. She should be able to track the source of the ICs. Regadrs Enrico

Sorry for my late response, I just come across your post. Here is my opinion if it could help someone

Both appear to have a printed markings which is very suspicious because the genuine ST parts are laser engraved very distinctively. However picture B looks very similar to the genuine part because:

1- The back of the device looks similar.

2- On the front face, PHIL appear in the molding which is similar to the genuine device.

There are some similarities as well as some marked differences in the writing. Hence both are suspicious and different from the genuine devices that I have (Supplied directly by STm). Picture A being the most suspicious.

Regards
