BQ20Z45-R1: What are the differences between p/n# BQ20Z45DBTR-R1 and BQ20Z45DBTR?

Part Number: BQ20Z45
Other Parts Discussed in Thread: BQ40Z50

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

Christian

  • -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.

  • 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.
