    Hi Tanya,

    Our TCA9517-Q1 is AEC-Q100 qualified for auto. 

    It is package drop in, but requires pull-up resistors on both sides of the device unlike TCA9803. 

    Also, the VOLB of TCA9517-Q1 is ~ 0.52 V typical. The offset on B-side is sometimes not compatible with devices whose VIL is < 0.4 V. 

    Regards,

    Tyler
