R11 clearance of pads on the top surface is 3.5mm vs the clearance on R13 only 0.6mm. The difference is given because of the smaller pitch capacitor on R13.

Additionally NSMD pad design.

(original text:

Design impact, since R11 has 5mm distace between plus and mins in contradiction to 0.6mm bei R13)
