Perhaps for the US and Orbital

But The Russian Federal Space agency  is using it in a Soyuz variant

To what extent it is to be used by Russia is unknown

Apparently the RD-191 derivation RD-193 will replace it sooner than later

Orbitals other payloads will I guess be launched on other available launch
vehicle with that payload performance availability

The wisdom of multiple suppliers of services demonstrates itself again

Perhaps the end of the N-1 rocket engine legacy?

Orbital Sciences 'likely' to stop using type of engines utilized in crashed

NEW YORK - Orbital Sciences says it will likely stop using the type of
engines that were employed when its unmanned Antares commercial supply
rocket bound for the International Space Station exploded moments after
liftoff last week.

The company says its investigation of the crash is continuing, but
preliminary results point to a failure in one of its two main engines.
Orbital says it still plans to fulfill its contract with NASA to deliver all
remaining cargo to the Space Station by the end of 2016.

Orbital Sciences Corp., based in Dulles, Virginia, says there will be no
cost increase for NASA. It will introduce an already-planned upgrade to the
Antares propulsion system early in 2016.

Orbital doesn't expect costs related to the accident to be material in 2015.
