Buy: 2SC1971 transistor

[VK4ADC]

I know eBay lists 2SC1971 transistors but most are probably fakes, and taking 3 weeks or so to discover whether it is a fake does not enthuse me.
 
What I am wanting to buy is a "real" new 2SC1971 device, a 175MHz TO220 device as used as a pre-driver in some Icom transceivers.

The direct equivalent is an NTE342 and that would suffice.

I am awaiting a reply from Icom re price and availability, but in the meantime, have any Forum members got one to spare (P&A please) ??

GOT ONE - THANKS FOR READING !!!

Hello Doug

Regarding 2SC1971 transistors: I believe an MRF237 is also equivalent, although not a TO220 package.

A 'real' 2SC1971 is a very rare commodity, apparently, because they haven't been made by the original manufacturer for decades.

I believe Eleflow is a reputable supplier if you want a suitable replacement. http://www.eleflow.com/

I found Eleflow during my web searches and had a look at their offering earlier. There is always a chance that someone in VK has one that they bought as a spare for a long-defunct radio. If I had to, I would accept a "pull" from a non-working Icom.

The device has to be a TO220 to be able to effect a repair in the Icom device and there isn't room to play with alternatives. I can't go too far off the characteristics of the original either as it is running in linear mode rather than Class C.

Anyone else got suggestions - or the device itself?

Sorry old man not want you want....

But Interesting to look into my transistor collection [first time for many years]  and  found a MRF237  [TO5]  final for a kenwood TR2200 portable 2 metre rig, not what you want ...

Also found  2SC2290   and  MRF 422 matched pair  finals for HF rigs from way back.

MRF492 finals matched pair  [6 metre amp finals?]

MRF 455 finals

2N5245  RF jfet i think

and 3SK121  

Amazing what you find when prompted  hi

cheers and thank you for the forum

I think you need to work out what $$$ you want for those devices as you may get some enquiries from people chasing them - that is if you don't need to keep them as spares because the original radios have 'moved on'.

Doesn't help me but you have "advertised" them in the right place
