A direct replacement doesn't exist. What kind of application is it?

But these are also made of unobtainium...

Hi, Wallace. The 2N1300 is a PNP Germanium RF-IF amp transistor.

Some of the "unobtainium" parts can be replaced with NTE cross-referenced parts. You might want to look for the NTE160:

Their cross-reference is an invaluable tool for repairs, especially on older equipment with oddball transistors or diodes.

Your part is available through:

Colourview Electronics

Try their cross reference next time. Their parts are usually suitable replacements.

Hello Jorgen,

Unless it is a single-cell battery application that has to run down to less than 1V it may be possible to substitute with a regular silicon transistor.

Industry Number : 2N1300 NTE Device Number: NTE160 T-PNP,GE-RF/IF AMP,TO-72

Hi Joerg,

That is for a batteries operated radio control model, and this broken transistor is on the receiver side. The receiver side is operating at

I may try a PNP transistor with a higher power rating to see whether it will work, as I do not have the circuit diagram for it and unable to check what is it for.

Thanks everyone for the valueable information.

Best regards

Wallace

Of course, if you replace a germanium transistor with a silicon, the biasing may become an issue.

Hello Michael,

Usually not, unless it was biased close to the rail. The only thing that happens is that Vbe increases by 400mV meaning the quiescent current drops a bit. Of course, in a final amplifier situation this can cause things like Iq to get out of hand but in a single stage amp location you are mostly ok.

Another issue to watch out for is oscillation. hfe and ft is usually much higher even for the cheaper silicon pnp varieties.

Hi !

We do have stock of the 2N1300 from MOT.

Can you tell us your idea price with QTY request ?

Thanks !

Hmm, i don't have the 2N1300 how ever, i do have a few
