RC4185 ?

[N_Cook]

The remnants of a Fedback FG600 England made function generator of 1975.
Someone clipped the legs of one of those canned devices of the time leaving
10 longish pins in the board. Overlay is a circle with a tab. He wrote
RC4195 and RC4185 on pcb. Now a Raytheon RC4195 looks right there, a dual
tracking +/-15V regulator but what was an RC4185 I cannot find any reference
to it , but it may have been the original device and he intended replacing
with a 4195.
The drilling pattern was 8 like standard DIL and one between 1 and 8 and one
between 4 and 5 but of course may have been bent to that form , from a
circular TO96 type package.
7815 + 7915 will go in there firstly for proving purposes in all likelihood

 

[N_Cook]

Plenty of reference to 4195, none to 4815. If the part ever existed
there should be some reference even as obsolete. Maybe a mental error.

I've looked in my contemporaneous sources and nothing
He actually wrote , very clear script,
RC4185NB
RC4195NB
which are valid suffixes for Raytheon

What does it all mean? who knows....

Here's a theory, maybe the lettering was abraded but he wanted to
memorialize what info he had right on the board before he headed to the
reference library or the parts store with the IC in hand.

Interesting you say that
Another IC he'd marked on the board , but still in place is a Plessey multi
transistor pack
It is that chalky print of the time and wrote
SL304?? 5C?
With good slant lighting , perhaps decades on I could confirm SL3045C

But RC4195NB is not a 10 pin pack if the 5th character was indistinct

RC4185TK ?

FWIW Usbid lists a RC4185TK manufactured by Raytheon with a date code
of 7925:

Is it a genuine outfit ?
ie does a "Request for Quote (RFQ)" return mean they actually have one
assuming you cough up 300 USD .

Although footprint is 10 pins , only 9 have traces to them, but wire size
legs rather than the TO66 package pins and overlay would suggest TO66. I
wonder if the 4185 was not-fixed +/-V.
My old Raytheon book seems to suggest they used TK suffix for TO99 and TO66

Hmm ... Could it be that your 4185 is one of Raytheon's latest
products which has been produced only for a short time?

Databook 1976: 4194/4195 voltage regulators
1985: 4194/4195 + 4191/4192/4193 (+ 4391) voltage regulators
1989: 4194/4195 + 4191/4192/4193 + 4190 (+ 4391 + 4292)
voltage regulators
19xx: ... + 4185??

When did Raytheon disappear from the semiconductor market?

Considering as possibility
