nRF51822-QFAC pin compatible with nRF51422-QFAC?

[mcintoda]

Is the nRF51822 pin-for-pin compatible with nRF51422?

I can't find any distributor stock of nRF51822-QFAC.

I see the eval kit has nRF51422. I don't need ANT functionality; What do you recommend I specify in my BOM?

As long as you register an account at Nordic (mypage.nordicsemi.com) you should be able to download the specs for both of those

www.nordicsemi.com/.../nRF51822

www.nordicsemi.com/.../nRF51422

under the 'downloads' tab. I believe those you can access without a product key, just need an account.

I looked at both and they appear to be pin-for-pin compatible, which was my understanding previously as well.

If you don't need ANT then the 51822 ought to be a cheaper choice.
