Every 93c66 well work.
Just pay attention that 93cXX can be read as 8 bit or 16 bit. I prefer to have a backup read of both.

Thank you for your reply i am using X100Pad and i think its reading in 8 Bit because its default and cannot able to change that.

So what i understand from your reply the above-attached picture of 93C66 are same.

Yes should be same just different revisions date codes etc
Upa or xprog is the best for eeproms carprog not so good

Thank you for confirmation its really helpful
