nRF514 and nRF518 fully equal/drop-in compatible with proprietary radio protocols?

[bvrm]

When using proprietary radio protocols only (Shockburst/Gazell) are there any difference between nRF514 and nRF518 chips? Do they behave totally equal so they can be used as drop-in replacements each other?

There is no difference between the two for proprietary protocols. The only practical difference is that the 422 allows you to run the ANT stacks.
