In this paper, we discuss the Bianchi type-I cosmological model in framework of symmetric teleparallel gravity say $f(Q)$ which non-metricity term $Q$ is responsible for gravitational interaction. We consider a special form $f\left( Q\right) $ function can be cast as =\lambda Q^{n}$, where $\lambda and $n$ both are dynamical parameters. Such choice viewed hybrid scale factor that leads to relation between cosmic time redshift $% t=\left( \frac{\alpha t_{0}}{\beta }\right) W\left[ \frac{\beta }{\alpha }e^{% -\ln \left( 1+z\right) }}\right] describes \Lambda $CDM Universe with expansion evolving from decelerating an acceleration phase. The best values parameters i.e. $\alpha $\beta would accord most current observational datasets then estimated. make use 57 points Hubble dataset, 1048 supernovae type Ia dataset 6 BAO dataset.
