ECM Hyundai Accent 2013 computer

Hello,

my Hyundai Accent 2013 only works for the 3rd change and the reverse. The fault code it presents is P0748 (Electric failure in Electrovalvula A of the pressure control [primary pulley].
The valve box was reviewed and all selenoids work and also the connector of the valve box. The lines from the computer to the box too.
The diagnosis is then the change of the ECM computer.

My computer has the E45b code and the number of part is 39127-2B890, but my problem is that I do not find it exactly that same part number, the ones I find are: 39127-2B100, 39110-2BAS, 39110-2BAE5 ...

Do you need to have the same part.
