It may be a coincidence, but in a previous life that exact same component gave us a major headache.
After sending the component for a failure analysis, it was determined to be fake.
A thorough investigation revealed that our board assembler had purchased the chip from a Chinese broker.
I know, I know: advice from a web forum is not ironclad expert opinion. Therefore, and depending on the dollar amount of the purchase, and/or the liability you will face if the device fails, that the devices are sent to a third party lab for analysis. They can scan for evidence of blacktopping, leads wetting or corrosion, going even to decaping and micro-photographing the die. They can also check the packaging conditions.
