Both Sony NEX-C3 and Sony NEX-5T have APS-C sized 16.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the NEX-C3 and NEX-5T sensor size comparison.
Sensor Size and Resolution Comparison image of Sony NEX-C3 and Sony NEX-5T Cameras
Sony NEX-C3 and Sony NEX-5T have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Sony NEX-C3 and Sony NEX-5T sensors have been tested by DxO and the results show that NEX-5T has a better overall score of 78, 5 points higher compared to NEX-C3's score of 73.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Sony NEX-C3
or the
Sony NEX-5T ,
including hyperfocal distance.
