It looks like a common mode choke. Surface mounted common mode chokes are often not in a standard package and do not have a standard footprint. If it is a common mode choke, the opposite terminals should measure less than a few ohms, and the terminals next to each other should be open circuit (measured when removed from the circuit). Common mode chokes rarely fail.
If you can get the schematic for the product, it should tell you exactly what the part and its part number is, then Google the part number.
