Hi Isagani,

Both sites are qualified. The minor package variations you pointed out are functionally inconsequential.

Best,

Sam

Hi Sam,

I have an additional question. Please refer to photo.

Please advise why the number or code in the decap device is not the part number THS4521IDGKR.

Is this valid and not necessary to put the part number in the device. Thanks

Seems the reply on the link is not the answer I want to know.

Hi Isagani,

I contacted the TI Quality organization to verify the material legitimacy raised in this post and they did verify that these are valid TI lots as per the information provided on the labels. They also stated that the marking on the die is an internal designator that was created when the product was initially designed and may or may not match the part number itself. The TI label is the main factor for determining whether material is legitimate or not from TI.

Best,

Sam
