Only the seismometer assembly was intended to survive the Ranger landing, which was highly energetic. "Soft-landing," in aerospace parlance, does not cover impactors, so it is quite wrong to say that any part of a Ranger spacecraft was intended to soft-land. However it is equally wrong to say that no part of the Ranger spacecraft (well, on some models) was expected to survive impact. Part of Ranger's mission was to collect seismic data from the lunar surface post-landing.
