Hi

Need advise on selection of a equivalent MOSFET device.

The original device specified is a STP80NF03L with the following specs, Vdss=30v, Rds=0.004 Ohm and Id=80A. However this is not available locally, and a suggested replacement is STP80NF10 with the following specs. Vdss=100v, Rds=0.012 Ohm and Id=80A. Is the increase voltage rating a significant problem. The component is part of a speed controller board.
