Are LTC2984/2986 software-compatible with LTC2983?

We have a design based on the LTC2983, but currently having trouble procuring them for an upcoming build. I see that the LTC2984 and LTC2986 are very similar parts, with the addition of EEPROM for storing data through power cycles. Assuming we don't need that feature, are the LTC2984 and/or the LTC2986 functionally equivalent in terms of how the microcontroller interfaces with them via the SPI port?
