Vishay Dale IFSC1515AHER470M01 Marking Problem

We purchased IFSC1515AHER470M01 components with date code 2549.

After PCB cleaning, the “470” marking on the components disappeared. Our cleaning process has not changed, and we did not experience this issue with earlier date codes.

Could you please confirm whether there has been any change in the marking ink, coating, material, manufacturing process, or production location for date code 2549?

Vishay has a variant ?

Hello andarsatinalma,

Welcome to the DigiKey TechForum.

There has been no PCN that I could see indicating any such change with the product. I’ll ask the manufacturer and get back to you once I have some feedback.

andarsatinalma,

A representative from Vishay answered me and informed that you have already contacted them on this and that they are awaiting more information from you on this matter.
