While they all share similar features, each Jupiter-2 is very different. While the version from the series is generally considered canon, each new incarnation of Lost in Space features their own, distinctive design. The new series, announced in 2014, will presumably feature a Jupiter-2 spaceship, which apparently resembles the original, but updated.
