Have you looked at ztx 451 / 551? Regards the 212 not sure what you have in the states but try a google search for equivelents...?

Hello Guys,

Thanks for the input on this. I did not do an ebay search originally because I did not know how crucial getting quality parts or a reliable manufacturer brand for transistors was. I find the BC212B transistors on ebay but they are discontinued here in the states through many of the suppliers. Seems that sellers in Europe have them. And Jacque, you have helped me out in the past many times so if I were to order from Brico-Loisirs I promise to only get one of each that I need.

If anyone knows new equivalents for the BC 142, BC143 or BC144, I appreciate it.

John

Hi,

I was able to find NOS BC141-142-143 on eBay France when I did my 4002. The seller is called Brico-Loisirs.

He still has them in stock. But please leave a few for me, don't buy the whole stock!

These transistors are not all that critical at all I use ZTX types for the bridge high current / voltage (1A / 65V but NOT 1A @ 65V lol) in a tiny package and very similar specs to the old transistors! Bc212 can be purchased new. If you are in the states then you need a 2n equivelent possibly. Try Google Search.

I agree with Blackrix above Littlediode is truly excellent for hard to find transistors and other electronic goodies :)

Equivalent Transistor Recommendations

jfrancis — Sun, 25 Dec 2011 22:02:47 GMT

Hello All,

I am repairing/restoring a Beogram 4002 model 5513 and wonder if I could get someone to recommended replacements for transistors. The ones in question are the Texas Instrument BC212B, BC142, BC143 and BC144. I am not finding these available any longer through the parts supplier I have used in the past. Are there equivalents I should consider for these and what manufacturer should I be looking for for quality transistors?

Any help would be appreciated.

John
