Part Number: TPS40210

I have TI part number TPS40210DGQR which arrived with copper/gold color leads, it seems to look like it has oxidation.

I saw at datasheet that this part number has NIPDAU | NIPDAUAG lead/ball finish

So it is ok to leads have a copper/gold color?

Hi Iliana,

Thank you for posting to the E2E forum.

Can you share a picture if the device / leads - interpretation of a color is sometimes misleading when done verbally.

Can you also confirm that the devices arrived with a proper sealing.

Can you also share a picture of the label which should stick on the package.

Thanks,

Stefan

Hi Stefan,

I'm attaching pictures.

This material is a transfer from another facility, it came just inside a box (not vacuum sealed), also it's MSL 1

Date code: 1807

So let me know your comments.

Hi Iliana,

I also think that this color is due to oxidation of the leadframe.
Esp. when checking the seal date which shows 06/22/18 (so more then 3 years) and the transport package was not vacuum sealed anymore.

You may also can contact the Customer support for further analysis Contact us | Technical support | TI.com

Best regards,

Stefan
