Yankee DogMar 14, Yankee DogMar 17, The original 2SC was made by Hitachi, and installed in a funny-looking rectangular package with a little “roof” on the top that slopes down from front to back.

On the other side the trannys are basically a mirror of the first side preamp board. I would never stick it in a low-noise circuit.

On one side, the transistors go in like normal. Sorry it’s hard to describe, but in a way, they do go in backwards sort of. Not backwards, or whatever: The original 2sc does look different.

Is that what you mean by “Some new-production 2SC’s have the same basing dxtasheet the 2SC, but those new devices are not installed in vintage gear”? Your name or email address: So looking at the data sheets I am not seeing it. A few years ago, “new generation” 2SC’s began appearing. At the time of manufacture, these were considered an excellent choice for a low-noise, small-signal transistor — and were used widely.


I’m trying to buy some 2SC transistors from Digikey or Mouser, but am not having any success at all with this part number to replace my 2SCs can anyone recommend an alternate, or, better still the correct Digikey part?

Then a similiar thread mentions to “put them in backwards”. EchoWarsMar 17, Share This Page Tweet. I really want to be sure before I put these things in.

What about the data sheets I have posted? By the early ‘s, the 2SC had proved itself as a wonderful small-signal, low-noise transistor, again with an acceptable bandwidth, so I began using it as a replacement for the 2SC I chose it because in the spec manual it was called out as a low-noice small-signal device with a bandwidth not dissimilar to the 2SC, and because the 2SC was used in many machines I encountered — and the device never seemed to fail.

Some new-production 2SC’s have the same basing as the 2SC, but those new devices are not installed in vintage gear.

The 2sc’s arrived today and they are installed. I replace them wherever I find them. In transistor selection, like many other aspects of electronics, the devil is in the details.

Things are working and 2sc58 fine. The old ones are now in my ‘rogues gallery’ Thanks again EW: HyperionMar 18, Luckily the board was labelled E C B so I just installed them keeping track of that. Now I’m just waiting for my caps to arrive so I can breath more solder fumes. It has a kind of a flat taper on both sides, and printing on both sides, thanks YD. AndymanJan 4, They simply aren’t to datashest trusted. It works fine as a basic, small-signal transistor, and is fine for many applications.

2sc458, 2sc2240 Clarification please

Yes, my password is: So, should 2SC’s of any age be replaced anywhere they are found? The issue here is not so 2sc4458 the noise level of the transistor, but the fact they need to be matched to each other in this situation. I consider many of these “new 2SC’s” to be counterfeits, i. I assume that as long as I pay attention to E C B, it will keep me out of trouble like when installing the 2sc when I install the 2sc
