ESD321: Top part marking

Winston Mau

Part Number: ESD321
Other Parts Discussed in Thread: TLV717P, TPS3831

Tool/software:

Your marking lookup tool states that "DD" is for ESD321DPYR. But we just received a reel of 10,000 and the marking doesn't match with what your lookup tools states.

The marking is either "AS" or "A5".

Could you please confirm the current component marking?

Thanks.

AS and A5 are markings for TLV717P and TPS3831 in the DQN package, which is quadratic. Can you show a photo?

Hi Winston,

This is a known issue where some material in the ‘DPY’ package coming out a certain assmebly site was incorrectly marked with A5 instead of the marking seen in the data sheet, and a recent audit has confirmed this. The parts received will match the shipping label sent to Sanmina and performance will not be impacted.

The A/T site has already worked to resolve this error, but the incorrectly marked material may be seen until the affected material makes its way through the system. These are the correct units and performance will not be affected.

Regards,

Sebastian

Hi Sebastian, thank you for your response. Would you happen to have a hard copy of the audit results with their findings?

This would really help clarify things over here.

Thanks,

Winston
