AC Power Supplies D630 XPS15 E6400

Hello,

I have a 90W AC Power Adaptor from a D630 that I no longer am using.  I have an E6400 with 2 power supplies one a full-size 130W (PA-4E Family, used for the dock) and a slim line 90W power adaptor (PA-3E Family).  The specks are identical to the D630 power supply (PA-10 Family). The XPS came with a 130W (PA-4E) that is the same as the E6400's.  There is a 90W available from dell for the XPS 15 also (same part number as the E6400). The specs on both the D630 90W and the E6400 90W power supplies are:

Input,  100-240V ~ 50-60 Hz 1.5A

Output 19.5V(19.5V) 4.62A(4.62A)

+ on both is the center pin, - is the outer ring and both the same size.

The question is can I use the D630 PA-10 power supply to power either the XPS or the E series seeing how the output specs are the same?

Thanks
