Low energy linear seesaw mechanism responsible for the generation of the tiny active neutrino masses is implemented in the extended 3-3-1 model with two scalar triplets and right-handed Majorana neutrinos where the gauge symmetry is supplemented by the A4 flavor discrete group and other auxiliary cyclic symmetries, whose spontaneous breaking produces the observed pattern of SM charged fermion masses and fermionic mixing parameters. Our model is consistent with the low energy SM fermion flavor data as well as with the constraints arising from meson oscillations. Some phenomenological aspects, such as the Z′ production at proton–proton collider and the lepton flavor violating decay of the SM-like Higgs boson are discussed. The scalar potential of the model is analyzed in detail and the SM-like Higgs boson is identified.
