This study delves into the modeling of electrically charged stellar structures under modified gravity f(Q). To deal with this modified gravity, we consider a linear function in f(Q) gravity expressed by 
, where 
is the coupling parameter. The formulation of field equations is reviewed, and the Heintzmann IIa solutions are utilized to find the solution to these governing field equations, and the MIT bag model is considered to tackle the system of field equations. The unknown constant values are obtained by matching the external Reissner–Nordström geometry with the internal space-time in the present case at the surface boundary. To check the model’s physical feasibility, we examine physical features such as energy density, pressure, energy conditions, equation of state parameters, stability analysis, adiabatic index, mass–radius relationship, compactness, and surface redshift. For this analysis, two representatives of the compact stars, namely, 4U 1538-52 with mass 0.87 
and radius 7.8 km and SAX J1808.4-3658 with mass 0.88 and radius 8.9 km, are incorporated. Graphical representations and numerical results confirmed the physical validity and viability of our model presented.
