TXB0104: need to know meaning for all characters on top mark

Tool/software:

Dear All,

I want to have your information about the meaning of Texas part#TXB0104YZTR.

Here is top mark characters "2A62KI" on my part whereas Texas allows me to know only device/part ID top mark as the below link.

Is "2A6" the lot code ? Is "I" plant code?

Best Regards,
