I think its the right one.Read the datasheet.Page 1 , 6x = Device Code , x = A, B, or C .The DOT is lead-free

6C, month 3 ,lead-free .(Note: Microdot may be in either location)

*Date Code orientation and/or overbar may vary depending upon manufacturing location.

The orientation means that the date code can be either vertical or horizontal .
