ADE9000 replacement (ADE9078?)

Hello,

Due to the current electronics lack, the ADE9000 isn't available on any distributor, so I'm looking for a replacement.

As discussed in this link the ADE9000 and ADE9078 are mechanical compatible (pin to pin), and as far as I've researched the ADE9000 is newer than the ADE9078 so I'd like to ask what functionalities I will lost if I "downgrade" to the ADE9078?

For example, VRMS ½, IRMS ½ rms voltage refreshed each half cycle, 10 cycle rms, 12 cycle rms are still available on the ADE9078? 

Which other functionalities could be missed?

In terms of register distribution and access, an MCU controlling the ADE9000 will be capable of controlling the ADE9078 with few/no changes?

Are there other options for replacing the ADE9000?

Thank you.

    Hi the ADE9000 has more features than the ADE9078 

    The ADE9078 does not have:

    VRMS ½, IRMS ½ rms voltage refreshed each half cycle, 10 cycle rms, 12 cycle rms

    VTHD ITHD, Dip Swell, fundamental measurements, IRMS, VRMS, VA, watt (does have fundamental var)

    sample rate is half of the ADE9000  resampled data is 64points for ADE9078 and 128 for the ADE9000. 

    ADE9078 has more psm modes than the ADE9000. For compatibility normal mode in the ADE9000 should be psm0 = psm =0

    This is the only pin for pin compatible part to the ADE9000. The ADE9000 is the only part that has  your example measurements "VRMS ½, IRMS ½ rms voltage refreshed each half cycle, 10 cycle rms, 12 cycle rms"
