Abstract In this work, the exactly solvable Schrödinger equation for s‐states of a class of multiparameter exponential‐type potential (E‐tP) is used to obtain the approximate ℓ ≠ 0 bound state solutions for the corresponding q‐deformed radial potentials. To deal with the effective potential, the Pekeris approximation for the centrifugal term is applied. The proposal has the advantage that, depending on the choice of the parameters involved in the E‐tP, several q‐deformed exponential potentials are obtained here as particular cases. That is, our proposition indicates that it is not necessary to use specialized methods to solve the Schrödinger equation for specific q‐deformed exponential potentials. At this regard, in order to show the usefulness of the proposed method, we consider the ℓ ≠ 0 bound state solutions of the q‐deformed Tietz, Hulthén, Manning‐Rosen, Shioberg, quadratic exponential, Wei and Hua among other potential models. Furthermore, with the example of the Hua potential we are contributing to solve the recent controversy on the energy spectra of this q‐deformed model. Moreover, in some applications considered in this work the results can be used to correct similar findings already published. Besides, the proposal is useful when considering new q‐deformed potentials with hypergeometric wavefunctions to be used in quantum chemical applications of diatomic molecules.
