Hi -  This is my first question for the forum.  

I am building RV8 w single aft battery/ dual alternator.  Ground power contactor and battery master battery contactors are aft.   Obtained both contactors from B&C with 1N5400 diodes.  Total of 3 diodes  (2  on the Ground Pwr Contactor  and  1 on the Battery Master Contactor.)

Diagram from Aircraft Spruce with the Piper jacks written by AeroElectric  showed using 1N5402 diodes on  the  Ground Pwr contactor.  Are there compelling reasons  to  swap out  my 1N5400 diodes with 1N5402 or other?
Thanks for reading and for responding.

Same current rating. Voltage ratings of 50V vs 200V.

When I buy diodes, I usually get higher voltage ratings because they typically don't cost much (if any) more in small quantities than lower voltage ratings. But if B&C shipped 50V rated diodes with their contactors, I'd be confident that 50V is good enough. (Even 1A current rating would be good enough for the shunt around the coil, but the 3A diodes are physically more rugged.)
