Science instruments aren't generic, you have to choose a scientific payload that gives you a chance to attain your objectives while operating both under monetary and power constraints. The instruments have also improved tremendously over the last couple of decades.
"Galileo’s camera and spectrometers revealed that the icy crust is fractured and frequently covered with material that appears to have originated in the ocean below. The Clipper’s radar instrument (Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) – principal investigator Dr. Donald Blankenship of the University of Texas, Austin) will see below the surface to investigate the structure of the shell, potentially all the way to the interface with the ocean below."
"The MAss SPectrometer for Planetary EXploration/Europa (MASPEX) (principal investigator Dr. Jack (Hunter) Waite, of the Southwest Research Institute (SwRI)) will measure the composition of gasses, ices, and organic molecules."
"The wide angle camera in the Europa Imaging System (EIS) (principal investigator Dr. Elizabeth Turtle of APL) will map the surface of Europa at 50 meter resolution in color to document the surface structure."
"During each of the planned 45 flybys, the spacecraft will travel close to the surface of Europa. At each encounter, the wide and narrow angle EIS cameras will record the surface geology in high resolution recording details as small as one meter."
Here is an overview of what we know about the mission now: http://futureplanets.blogspot.se/2015/06/nasa-goes-first-cla...
