Replacement SmartFade power supplies - what to look for

I found, what appears to be the exact power supply that comes with the SmartFade for a dirt cheap price. HOWEVER, the end that plugs into the console is a millimeter too narrow!

I'm not concerned that my $5 purchase didn't work out, however, I would like to know what specs to look for if I don't want to pay for the "international" plug that ETC sells.
