SO# 494281

Hello, our customer is concerned about the state of the contacts of delivered parts with P/N: SN74HC273N, assuming rust, or oxidation.

We told the customer that this should be ok, with hint to the PCN: 20120223003A "Add Cu as Alternative Bond Wire Metal for selected devices".

But the customer would not accept this. Therefore I hope you can confirm that these parts should be ok, by attaching pictures of these parts, or you can advise differently?

The pictures show the same part-number, but with different appearance:

Can you please advise?

THank you very much.

Best regards

Adnan
