Title: Transistor supply issues and changes
Post by: andywragg on June 09, 2010, 07:04:46 AM
Hi,

Am speccing up a build and the parts list has a quartet of 2n5089 transistors. These arent available here in the UK although I can get the 2n5088G.

My question is what would be the effect if any of using this transistor over the the one in the build specs?

Data sheet is in the link.

How soon do you need those 2n5089´s ?

I beleive I have a couple of those. If not, I´m ordering stuff locally this week anyway (The Netherlands). I´ll have it one day after ordering, and would be happy to order 4 of those and pop them in the mail for you.

I won´t get back home until sunday though, so keep that in mind...

Thanks Boom.

Haberdasher (and a bit of my own research) has confirmed that the 5088 is a valid alternative and is actually used in some of the older variants of the project I need it for, so I'll pass on your offer.

Thanks again

Andy

The 5089 is the lower noise, higher gain version of the 5088. They are completely interchangeable.
