The ac dynamic magnetic susceptibility was used to study a cation substitution on critical fields in polycrystalline (Zn_{0.87}Sn_{0.048})Cr_{2.02}Se_{4} and Zn_{0.93}[Cr_{1.95}Sn_{0.05}]Se_{4} spinels with tetra- and octahedral coordination of Sn ions, respectively. An increasing static magnetic field shifts the Néel temperature T_{N} to lower temperatures while a susceptibility peak at T_{m} in the paramagnetic region - to higher temperatures. Below T_{N} the magnetic field dependence of susceptibility, χ_{ac}(H), shows two peaks at critical fields H_{c1} and H_{c2}. The values of H_{c1} decrease slightly with temperature while the values of H_{c2} decrease strongly with temperature, especially for spinel with octahedral coordination of Sn ions, suggesting a weakness of the ferromagnetic component.
