  A variant for the superspin one-half massive superparticle in $ 4D $, $
\mathcal{N}=1 $, based on Dirac superfields, is offered. As opposed to the
current known models that use spinor chiral superfields, the propagating fields
of the supermultiplet are those of the lowest mass dimensions possible: scalar,
Dirac and vector fields. Besides the supersymmetric chiral condition, the Dirac
superfields are not further constrained, allowing a very straightforward
implementation of the path-integral method. The corresponding superpropagators
are presented. In addition, an interaction super Yukawa potential, formed by
Dirac and scalar chiral superfields, is given in terms of their component
fields. The model is first presented for the case of two superspin one-half
superparticles related by the charged conjugation operator, but in order to
treat the case of neutral superparticles, the Majorana condition on the Dirac
superfields is also studied. We compare our proposal with the known models of
spinor superfields for the one-half superparticle and show that it is
equivalent to them.
