In this work a study of a set of relativistic hadronic point coupling models are made analysing the relation among this models with the hadronic nonlinear ones. We show how to obtain, rigorously, the point coupling models from the finite range ones by the hypermassive limit of the changed mesons. The point coupling models are discuss in the zero and finite temperature regime by it equations of state and then we compare this equations with the Walecka nonlinear models ones. A particular case of the point coupling nonlinear model that discuss the approach among the scalar and vectorial densities are analyze and the calculation in zero temperature regime to become analytical. A discussion about the correlations among the observables in zero temperature regime in the critical parameters are presented to a set of hadronic nonlinear models.
