CA3079 small qty required

Thu Nov 18, 2010 2:32 am   

I need 10 - 15 of the above to keep a number of old egg incubators going for a
few more years. If anyone has these could they please email me direct with
price.

Thanks

According to http://www.talonix.com/skrepl.htm
SK3541 and NTE914 are equivalent. The NTE914 is discontinued, but there's
7 in stock according to http://www.findchips.com
There's also 4 of the SK3541.

Thank you JW and Michael... I found the reference to SK3541 earlier but that is
just the company stock code for the CA3079. Unfortunately, as with most
component brokers they have minimum order values of around $200 and that is more
than my customer wants to pay. I am thinking a slight re-design using Atmel
T2117 might be a possibility. The circuit is so simple it could be bashed up
using Vero stripboard.

Thanks for that. If all else fails then I might give them a go...

Oops - you beat me to it. Should have read the thread fully...

Earl Andrews http://www.earlandrews.com/ has a qty of 15 NOS CA3059 at $4.70 ea
so I plan to relieve him of them. The 3059 has some additional internal
circuitry connected to pins 1, 6, 12 and 14 but the PCB they will be used on
does not connect anything to these pins so it should be a plug in functional
replacement.

The SK line was RCA's universal replacement line, just like Motorola had
their HEP line and then later ECG and NTE had their replacement lines.

Some of those replacements were iffy, especially early on when the lines
didn't have that many devices, so you'd get crosses that were vaguely
equivalent rather than identical. But since RCA created the CA3079 and
RCA originated the SK line, chances are good that the SK number is
in fact the proper equivalent.
