What are the differences between p/n# BQ20Z45DBTR-R1 and BQ20Z45DBTR?   We're looking to buy p/n# BQ20Z45DBTR-R1 but its status is NRND.  Is p/n# BQ20Z45DBTR the direct replacement?  

Thanks for your help

    -R1 is the shipping package, which indicates that device will be shipped in tape reel

    Hi Steven, 

    Thank you for your quick reply.  The cost of p/n# BQ20Z45DBTR from Digikey is $5 ea. vs. p/n# BQ20Z45DBTR-R1 @ $9.50 ea., so I think there's more to it than just the packaging.  Would you please check and advise the differences between the 2 part numbers? I also just found a thread on this forum dated June 5, 2018 regarding the same question. 

    Q:  

    "Part Number: BQ20Z45

    Hello,

    We have a customer asking the following:

    Customer received this:
    BQ20Z45DBTR

    He needs to know if it is the same as the -R1, could someone please confirm and advise?

    Hi, Christian

        Normally, sales will be answering the questions related to price. different prices do not necessary indicates the individual devices are different. for bq40z50 question, I will need to align with David before I come back to you

    Hi, Christian

        I made a mistake here, -R1 is a firmware version number, so bq20z45DBTR and bq20z45DBTR-R1 are different on FW version.
