    Hi Matsuoka-san,

    The TPS2042B-Q1 is qualified for automotive applications, so it need to pass the AEC-Q100. So there are some specs that will be more stringent, such as the high-side MOSFET resistance is 105 mohm, but the TPS2042B is 70mohm, so I think it will be ok that change from TPS2042B to TPS2042B-Q1.

    Best Regards,

    Kuno
