    Can you check CPR251124173 , 

    We face issue in Date code 2425 which is received from Texas Instruments.
    In board level , two locations of this part are mounted U4 and U5. While replacing the board with the same date code 2425, the board failed.
    But when we replaced the isolator with a date code of 2307 the board passed testing. 
    Pls let us know if there are any changes / modifications done in the year 2023 & 2024
