There are some non-AMP equivalents that don't seem to be made quite as
well, perhaps you had some of those? I've cursed those on occasions when
I've had to make the opposite-to-normal gender of power connector.

AMP changed the numbers at some time in the last few years, but I think
some of these may still be correct:
female contacts AMP 163304-2 (18-20 AWG)
female contacts AMP 163306-2 (14-18 AWG)
male contacts AMP 163305-2 (18-20 AWG)
male contacts AMP 163307-2 (14-18 AWG)
AMP used to have a pretty good website. A bit graphics-heavy, and a little
tedious at times, but al the info was there. Tried that?

Funny you mention that, I was looking for the same thing the other evening.
I can find the pins and shells but the biggest two-row shells I can find
easily are only 8+8. I want 20+20, of course. And I can't find those
cable grips at all...
I did find a very similar product (there are lots that nearly fit the bill
but this looks closest) made by Methode. They do 20+20 in their MEMTF
series that look very like black Berg ones, and the female crimp "pins" are
gold-plated like the better Berg ones. Still no cable clamp, though.
Fujitsu so something similar (M100 series), and there's a cable clamp, but
it looks kind of like a squashed D-connector shell -- not what I want for
my BC101V cables and oters that enter from the side of a board.
Harwin also do a range, called "C-Grid III", you'd want the 90142 series
(dual row).
I used to get BERG (DuPont, now owned by the Framatome Group, FCI)
connectors from a company in the UK called Electrospeed. Sadly, they no
longer seem to have the right connectors in the catalogue, but I found the
part numbers in the Newark catalogue -- which might be more helpful to you.
They're also in the Farnell catalogue.
The housings are "Bergcon" "Mini-Latch housing, 65043-series double row,
0.100" centers":
Newark Berg

There are bigger sizes too. The female pins are "Mini-PV crimp-to-wire
receptacles":
98F2828 47747-000 22-26 AWG std spring force 100? tin
98F4590 48266-000 18-20 AWG std spring force 30? gold
98F4588 48235-000 ... AWG std spring force 30? gold
98F5796 48238-000 28-32 AWG std spring force 30? gold
89F4587 48234-000 2x26 AWG high spring force 30? gold
^^ typo? I don't know
50F8733 48236-000 28-32 AWG ultrahigh spring force 30? gold
50F8734 48239-000 or 2x26 AWG ultrahigh spring force 30? gold
04F1609 47750-000 22-26 AWG ultrahigh spring force 100? tin
You can also buy the daisy chain jumper wires on reels. Remember those?
Used to make up the vital link on the BC01V, the link from Tx- to Rx- on
DLV11-J's, and for loopback plugs. A snip at UKP166.36 per reel. The
"lightweight rugged handtools" in two shpaes and five exciting sizes, range
from UKP385 to UKP503. Thankfully the rest of the range, the connectors
themselves, is more affordable! Still no cable clamps, though.
