Dear All,
As the BT138X-600D triacs from NXP were only available at Mouser by thousands, I ordered some on aliexpress.
I received them, but their package seems to be of very low quality compared to the other triacs I have
of similar values from NXP (see the attached pictures).
I highly suspect that they are fake. What do you think ?
If some one has an thrustful BT138X-600D, can he post a picture of it for comparison.
Thanks
Don´t know... but.. Did you compare them just with your eyes? May be a test circuit could help you to understand if you can use them as replacement or not.

Yes, up to now, I just compared with the eyes. The difference with the other NXP triacs was so flagrant that I did not even made an experiment, which I may do later on if this is the only way, but this needs some time and a proper setting to test
the component at full load.
I have send a message to the supplier who says that the parts are genuine.
I send also a message to NXP with no answer up to now.
The pins of the triac are of glossy metal that looks very flimsy for a 12A triac.
The overall quality of fabrication is very poor : printing is not even; plastic is not well pressed.
This is why I ask on the forum, hoping that someone will have a genuine part to compare.
For information, this is the message I received from NXP
From the picture, it is high possibility counterfeit part. While I would suggest you to purchase from authorized channel.
