PCI2050B: PCI2050BIZHK vs PCI2050BIZWT

Part Number: PCI2050B

Dear Technical Support Team,

Are PCI2050BIZHK and  PCI2050BIZWT same bare chip?

Datasheet has both packages and it seems specs are the same.

Best Regards,

    Hi,

    The ZHK is a MicroStar BGATm packaging that were redesigned using a laminate nfBGA package (ZWT). The nfBGA package offers data sheet-equivalent electrical performance and data sheet-equivalent or better thermal performance. It provides the same X and Y dimensions as MicroStar BGA, and provides pin-to-pin and footprint compatibility. 

    You can see this app note for more detailed information, https://www.ti.com/lit/ug/sllz077/sllz077.pdf.  

    Thanks

    David

    Hi David,

    Thank you for your reply. I understand that packages and electrical performances are  equivalent or better.

    If I replace from PCI2050BIZHK to PCI2050BIZWT, should I test again on my system to see if there is a problem with my application?

    If PCI2050BIZHK and PCI2050BIZWT are exactly the same or better, it would be nice to omit the verification.

    Best Regards,

    Hi,

    The electrical performance is equivalent between the two packages, so I do not see any performance issue when changing from one package to the next package. But I would still do a limited set of testing just to double check.

    Thanks

    David
