aleph-3 transistor replace

[space2000]

hi,

i want to understand about aleph-3 using the transistor MPSA18... which will be best replacement of this transistor?

MPSA18= (Replacement) 2N5551 or BC550c


thank you

Generic transistors work fine. The MPSA18 is a high gain device,
but anything over 100 will work.

which one have high HFE......

2n5551 or BC550

thanks

space2000,


BC550 hfe 270 > 520
2N5551 hfe 50 > 200

In your case the BC 550 will be fine.

Regards.
