Transistor substitution

[62vauxhall]

Regarding a Kenwood KA-7300 integrated I've been picking away at.

There are two transistors on the power supply board, a 2SC1567 (TO126) and a 2SC1681 (TO98-1). The protection relay on the same board does not engage and I've read that it's common for the "driver transistor" to fail in this amp. I believe the transistor in question is the 2SC1567. Because it's not involved in any signal path, there is supposed to be some latitude on what one can use to replace it.

2SC1567 data:

Polarity: NPN
Maximum collector power dissipation (Pc), W: 3
Maximum collector-base voltage |Ucb|, V: 100
Maximum collector-emitter voltage |Uce|, V: 90
Maximum emitter-base voltage |Ueb|, V: 6
Maximum collector current |Ic max|, A: 0.12
Maksimalna temperatura (Tj), °C: 200
Transition frequency (ft), MHz: 40
Collector capacitance (Cc), pF: 20
Forward current transfer ratio (hFE), min: 20
Package of 2SC1567 transistor: TO126

I have on hand a KSC3503 and the pin out appear to be the same but can or should I use it? The emitter-base voltage is lower at 5 vs 6

KSC3503 data:

Polarity: NPN
Maximum collector power dissipation (Pc), W: 7
Maximum collector-base voltage |Ucb|, V: 300
Maximum collector-emitter voltage |Uce|, V: 300
Maximum emitter-base voltage |Ueb|, V: 5
Maximum collector current |Ic max|, A: 0.1
Maksimalna temperatura (Tj), °C: 150
Transition frequency (ft), MHz: 150
Collector capacitance (Cc), pF: 1.8
Forward current transfer ratio (hFE), min: 40
Package of KSC3503 transistor: TO126

I happen to also have NOS of the other 2SC1681 transistor so can replace that one easily enough if need be,

Looks like it will do for a relay driver...
