Default Alpine 1505 transistor subs?

Anyone know of good subs for the 2SC3421/2SA1358 series pass regulator transistors?

Thanks.

They have thousands coming in. Email them. It could be an error that they'd want to know about.

yea, I could. Currently fighting with mouser and their weird end-user export notice crap. My order got held up, so I am already in a battle with them.
