DC Jack Plug In for Arduino DUE

Hello all,

I purchased 5.5 x 2.1 mm plug in for Arduino DUE DC power jack same as UNO, but it's bigger than female side in Arduino DUE.
I couldn't find any information about it online, so I thought it should be same as UNO's size.
What is the exact size of DC Jack for Arduino DUE?
Thank you.
