Does anyone know of any NTE2320-equivalent ICs?

The NTE2320 has 2 NPN and 2 PNP transistors, in a 14-pin DIP package
(two matched pairs).

Mouser.com part number is 526-NTE2320. Link to datasheet is there.

It's fairly expensive ($47 for 10). So I'd like to find a cheaper
equivalent, if possible.

It needs to be in a through-hole package (or easily hand-solderable).
But it doesn't necessarily have to be 14-pin DIP.

Thanks.

Thanks, Franc Zabkar!

It looks like the MPQ6501, MPQ6502, and MPQ6002 are in 14-DIP (TO-116)
packages, with the same pinouts as the NTE2320. The MPQ6700 appears to
be a surface-mount part.

And it looks like the specs of the MPQ6502 and the MPQ6002 match those
of the NTE2320, basically exactly. Apparently, they each contain two
2N2222 and two 2N2907, as two complementary matched pairs.

Unfortunately, neither Mouser.com nor Digikey.com stocks the MPQ6502 or
MPQ6002.

I'll do some searches and report back with any sources I find, for the
sake of the archive. In the meantime, if anyone already knows of any
sources, please post the information.

(P.S. I didn't yet find any info about the TPQ parts that were
mentioned.)

Thanks, Franc!

I did find the Sprague datasheets, for the TPQ65xx parts. I can't
remember WHERE; maybe through the allegromicro.com website. But
thanks for offering.

And I think that TI was also mentioned as a manufacturer of the TPQ
parts.

The MPQ6700 is in stock at www.mouser.com. But only in surface-mount
form, as far as I can tell. But, it looks like it's the same size as a
DIP-14 package. So maybe I could use it. Unfortunately, it has a
different pinout than the others, which would mean changing a PCB
layout.

By the way, I think that I was wrong about the pinout of the MPQ6002.
It's slightly different than the others, if I recall correctly.

At any rate, I now need to find a source of supply, for something like
the MPQ6502. I have found them, from various suppliers of obsolete
ICs, on the web. But I haven't quite been able to find out, yet, if
any equivalent through-hole IC is still being manufactured (besides the
NTE2320).

Any additional info, or sources, would be greatly appreciated.

Update:

Brett Singer of Central Semi has been kind enough to send me free
samples (4 each) of the MPQ6502 quad array (2 NPN + 2 PNP in DIP14
case), and also the 2N3811A, 2N3811, 2N3810A, and 2N3810 dual PNP parts
(TO-78 cans). [The "A" versions of the duals are spec'ed for matching
to within 1.5 mV Vbe and 5% hfe. And the non-A versions are spec'ed to
within 3 mV Vbe and 10% hfe.]

I'll let you know how they work out.
