New exact solutions of Einstein’s field equations (EFEs) by assuming a linear equation of state, 
, where 
is the radial pressure and 
is the surface density, are obtained on the background of a paraboloidal spacetime. By assuming estimated mass and radius of strange star candidate 4U 1820-30, various physical and energy conditions are used for estimating the range of parameter 
. The suitability of the model for describing pulsars like PSR J1903+327, Vela X-1, Her X-1 and SAX J1808.4-3658 has been explored and respective ranges of , for which all physical and energy conditions are satisfied throughout the distribution, are obtained.
