Help Discontinued Transistor

[Life is an Enigma]

I am looking for a comprable replacement for a power Transistor for the discontinued 2SC4910 here is data sheet for it. Any help would appreciate.

They are still available if a bit pricey.

I'm sorry. I don't see it on the diagram.

I'm sorry. I don't see it on the diagram.

On the last page of the Schematic it's the Q903 Q904 Q910 Q911 power Transistor Bottom right side of the page of the Schematic.

2SC2491?

2SC2491?

Yes I did look for a supply for those but only place I can find them is Ebay that's a 50/50 chance if they are any good that why I was looking for another power Transistor off the shelf to take it's place.

I was confused because that's not the number you posted.

The D44vh10 is a good high-speed transistor that may work.

Not something to panic over -- driver transistor in TO-92 -- you have a lot of choices but to make life simple make sure the pinout is the same. Something like the 2N5087/5088 is EBC.

D44 is TO-126 if mem serves correctly. I use these in voltage regulators.

The D44vh10 will not work the Emitter & Base switched around.
D44vh10
1 : Base
2 : Collector
3 : Emitter

2SC2491 & 2SC4910
1 : Emitter
2 : Collector
3 : Base
