TCAN1051V-Q1: Can MCP2561/62 be replaced with TCAN1051V-Q1?

Part Number: TCAN1051V-Q1
Other Parts Discussed in Thread: TCAN1042-Q1, TCAN1042V-Q1, TCAN1042HV

 Hello guys,

 One of my custmers is looking for TI CAN transceiver IC which MCP2561/62 can be replaced with.

 How about TCAN1051V-Q1?

 Or do you have any other device?

 Your reply would be much appreciated.

 Best regards,

 Kazuya.

    Kazuya,

    For the MCP2561, the TCAN1042-Q1 would be the correct replacement device, the only difference pin 5 on the TCAN1042 is a no connect where it is a SPLIT pin on the MCP2561. See this post for an explanation on the SPLIT pin and why it isn't included on TI's modern CAN transceivers.

    For the MCP2562, the TCAN1042V-Q1 would be the correct selection. It has the VIO feature on pin 5 just like the MCP2562.

    Please let me know if you have any other questions.

    Regards,

     Hello Eric,

     Thank you very much for the prompt reply. Your reply is very helpful for the customer and me.

     I will tell them the parts number.

     By the way, I searched TI device using  BOM & cross reference tool after asking you. But the parts number was not found.

     Do you know why?

     Thank you again and best regards,

     Kazuya

     Hello Eric,

     The customer doesn't need automotive grade.

     But TCAN1042V is not active.

    Can TCAN1042HV be used?

     Thank you and best regards,

     Kazuya.

    Kazuya,

    Yes, TCAN1042HV can be used, the only difference is the CAN bus pins are rated for +/-70V in the -H version. Non-H version the CAN bus pins are rated for +/-58V. 

    If the customer doesn't need that high of CAN bus protection, the TCAN1042V-Q1 would likely still be the best choice even if they don't need automotive qualification.
