I moved the post to our High Rel group so they can assist. Even though it has a commercial temp range, it comes from the LM311-N-MIL family.
We reached out to their apps team offline as well so they are aware of the question.

Hey Dan,
LM120K-5.0/883 is indeed obsolete. I've attached the PDN.
We don't have an exact P2P replacement so I'd recommend the UA79 series as the closest alternatives.
