  We present a supersymmetric 3-3-1 model with exotic quarks and a charged
lepton as an extension of the MSSM model with anomaly free three generations
The scalar sector is studied with six triplet Higgses and the mass spectrum for
light Higgs scalars are found to obey MSSM like predictions .The trilinear
Higgs term in 3-3-1 is found to be consistent with the bilinear mHuHd term of
MSSM and play an important role in the tree-level mass spectrum of scalars.
