Both Nikon D5300 and Nikon D5500 have 24.0 MP resolution sensors but Nikon D5300's sensor is APS-C (23.5 x 15.6 mm ) and Nikon D5500's sensor is APS-C (23.5 x 15.6 mm ).
Since Nikon D5500's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Nikon D5300.
Another similarity between these two cameras is that both Nikon D5500 and Nikon D5300 sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.
Below you can see the D5300 and D5500 sensor size comparison.

Nikon D5300 and Nikon D5500 have 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. Nikon D5300 and Nikon D5500 sensors have been tested by DxO and the results show that D5500 has a better overall score of 84, 1 points higher compared to D5300's score of 83.
