Diode 95SQ015 end-of-life (K2 D10)

The high-current low-drop diode 95SQ015, used in the K2 (it replaced
D10, SB530, because of it's favorable voltage drop) seems to be out of
production and out of stock in the likes of Mouser, Digikey and
Farnell/Newark.

I hoped the component was just replaced by a SMD version but that
doesn't seem to be the case. From what I can see, low-drop diodes exist
but not with the current ratings that the 95SQ015 has.

Has anyone found a replacement?

Just completed building a K2 kit. They had an SR1503 diode for D10 on the
RF board.

The difference in forward voltage drop between the 95SQ015 vs. the SR1503 under transmit load current is only about 0.15 V. Probably not worth the trouble to substitute the former.
