Mirage's self protection system can jam AMRAAM missile while none of F16 variations is able to jamm or trick MICA IR or escape its thrust vector by manouvering.
Also Viper's AESA has small azimouth scan & poor cooling which resulted in mediocre radius. By applying smart tactics you can exploit its weaknesses. Its main advantages is parallel functions (for example Air to Air, Air to surface & syntetic aperture scan at the same time) & high endurance in EW.
Mirage 2000-5 provides sufficient cooling for its radar & self protection system
