2N5089 Transistor Alternatives

[fornio]

Hello - I purchased both the Plecostomus Fuzz and Squidward and both of these utilize 2N5089 transistors. It appears Tayda does not have those in stock (Small Bear does) but is there a common alternative for the 2N5089? I'm okay with ordering from two places if necessary - but, was curious if there was an easier sourced alternative. Thanks in advance.

2n5088 should do the trick, MPSA18 as well

So, I may have answered my own question - but in looking at the 2N5089 datasheet it seems to imply that the 2N5088 transistor is essentially identical. The only difference I can see is a that the 5088 has slightly higher breakdown voltages which seem well above what this circuit would operate at.

So, would this be a good replacement?

Thanks - was writing my update as you were writing yours.

Last time I needed some, I just got the lead free version from mouser

The 2N5089 is a higher gain version of the 2N5088.

It'll work, it just might not have quite as much gain depending on the circuit.

You might consider going to Mouser and stocking up on 5089s - pretty common in pedal building.
