Well spotted, it was getting late last night.
Another potential candidate here

Saturation current is 1.3A and the resistance is 0.042 Ohm instead of 0.048. Not sure how much difference it would make???
Another way would be to get it from DigiKey Au and get more parts from them. Free shipping on orders over $200... otherwise $34. That's why I never order from them.
