TLV4021: check physical marking (so#379589)

Tool/software:

Hi Tech,

P/N#TLV4021R2YKAR

D/C: 2320

Our customer received above parts and found no marking on body, NOT matched with the spec shown marking as “6”.

Please see attached images for details.

Could you help check and advise if parts correct?

If yes, is there any PCN about marking change?

Thanks.
