Hyper-Berkeley cardinal

Let define cardinal $\kappa$ as hyper-Berkeley if for any transitive set $M$ what $\kappa$ $\in M$ exist elementary embedding $j$ where fixed point $\lambda$ above critical and $\lambda<k$.

  1. This cardinal is equiconsistent with $ZF$+"club Berkeley cardinal"?
  2. Are consistent to $ZF+BC$ (Berkeley cardinal)?
