  Transverse momentum spectra of charged particle production in heavy-ion
collisions are considered in terms of a recently introduced Two Component
parameterization combining exponential ("soft") and power-law ("hard")
functional forms. The charged hadron densities calculated separately for them
are plotted versus number of participating nucleons, $N_{part}$. The obtained
dependences are discussed and the possible link between the two component
parameterization introduced by the authors and the two component model
historically used for the case of heavy-ion collisions is established. Next,
the variations of the parameters of the introduced approach with the center of
mass energy and centrality are studied using the available data from RHIC and
LHC experiments. The spectra shapes are found to show universal dependences on
$N_{part}$ for all investigated collision energies.
