Default Re: 20 pin 8A on HP 250 G4 mb - voltage regulator?

Hi, right by the power charger port is a Dual Uni-Directional ESD Protection Diode which is shorted, I get no O.L. Beep like I do most of the capacitors and the other Dual Uni-Directional ESD Protection Diode near to it.
I have searched and came up with a possible substitute and also I notice there is comparable of the same component on Ebay which are much cheaper.
Can you tell me is the two components are compatible I can post the original first then the possible replacement and a link to Ebay where possible cheaper replacements might be.
