What's the smallest 8-pin connector available? It's for occasional use but it must be easy to insert/remove whatever cable it would accept.

Is it FFC?

"About 8,460,000 results"

Thanks for narrowing it down for me. :-)

That's how narrow you're search criteria are... What's small? What currents? Voltages? Hand solder? etc
Use fricking code tags!!!!

Fair enough.

3mA, 3.3V. Hand solder.
Size is the question, but no larger than 10x5x5 mm.

Sorry, I thought the criteria you set out was vague.
I am sure if you look at some of the offerings on the page you can come to a decision.

How about 4 by 4 JST or DuPont connector?

Is this cable to cable or cable to chassis?

You can make your own if it is cable to cable.
Get 8 male pins, 8 female pins, solder to wires, heat shrink each pin, then heat shrink the group of 8.
You can polarize the connector by having 1 male and 7 female then 1 female and 7 male.

Okay, it was a dumb question. I don't know what's available and couldn't pick a JST or DuPont connector out of a lineup. I suppose it was like asking how you program an Arduino.

I want to be able to occasionally connect a cable with 8 wires to an AVR that is on a small PCB. It's the connector on the PCB that I want to be of minimum length, width and height. An FFC connector is one possibility but I'm sure there are many others.

I have used 4X4 IDC, JST and DuPont.
These all are a good choice.

At the risk of being accused of a thread hijacker  ;)  is there a 1mm pitch connector similar to the DuPont style that can be hand crimped? I tried Element 14 but got lost in the sheer variety available, and all the 1mm stuff seemed to be for pcb mounting whereas I want cable fix.

And you can find these in 10 x 5 x 5 mm size or less?

you could take a look at jst series connectors.

Be aware though that once you go below dupont size the crimps get very fiddly and the required crimp tools get very expensive.

Addendum.
Professional crimp dies can cost 400.

Pololu do a crimp for 40 which is ideal for dupont.

They can be used to do an acceptable crimp on jst though.
Its fiddly precise positioning and two crimping operations are needed.

Measured DuPont.
10mm long, 5mm wide and 15mm long (in the direction of the cable).
