Part Number: CC2590
I am designing a board based on CC8520 with external CC2590. The design is based on swrr079.
However, in the future, I may need higher output power, so I would like to make a design which is compatible with both CC2590 and CC2591.
Are CC2590 and CC2591 directly replaceable?
Should I add anything else in the design?

Thank you for your answer; but the original question seems not answered.
The question is (slightly rephrased) if the CC2591 is drop-in compatible with CC2590 or that modifications are required.
I, too, have created a design based on evaluation kit PCB (even using the TI provided gerbers), but am struggling with poor range with CC2591 in place:
6 meters indoors line of sight, while AN089 "Real World Range Testing Using CC85xx" suggests even with CC2590 10 meters should easily be possible.
So while I appreciate the pointer CC2591 is NRND, would still like to understand if it is drop-in replacement for CC2590 and, considering PCBs are already made, is even recommended to replace CC2590.
(or better stick to CC2590?)

Thank you for your reply, TER.
As mentioned, I used the Gerbers as shared by TI;
now taking another fresh look at the schematic I see there is a capacitor to pin 1 that is only to be populated when C2591 is used.
So I am good for the PCB layout (plus on the boards where I used CC2591 I did populate this capacitor).
So on to the next potential source less-than-expected range, which is apparently the number of slave devices the master is configured to expect.
(currently have set it to 4 with only 1, sometimes 2 slaves for testing).
