Hi, Team,

My customer planed to use PCA9544AZQNR, but the device is EOL. Could you please recommend pin compatible device with PCA9544AZQNR?

Best Regards,

    Hey Satoshi-san,

    Unfortunately we do not have a pin to pin replacement for the QFN package.

    Is it possible for the customer to switch to our TCA9544A and qualify that device in the TSSOP package? We would be able to provide a better cost structure for this device than the PCA variant they are currently using.

    Or is size the main factor for choosing this device?

    Thanks,

    -Bobby
