Please help me identify these PCB connectors

I need to replace a cable on a piece of equipment. The ends of the cable
connect to PCBs using the type of connector I'm used to seeing all the
time when I dismantle stuff. However, now I actually need to order them
to make my cable, I can't find the right part to order from RS (common
supplier here in the UK).

Here is a picture of the two ends of the cable I need to replace:

I know these are generically PCB header plugs, but the problem is that
they're not at the 0.1" spacing common to hobby electronics. I measure
18mm over the 8 holes, or 2.25mm pitch, and that doesn't seem to be a
standard size. Am I in fact fractionally off and searching with the
wrong numbers?

The white one also has a particular shape to fit the socket on the
board, and the low profile is important to fit inside the case.

Can anyone tell me what name or term I should be searching for, and
where (ideally in the UK) I might buy a small quantity if they can't be
found at RS?

Cheers,

Pete

Pete-

We used to use the one on the left where I worked and we called them
Berg connectors (Wikipedia, Google it). At least the left one looks
familiar. If I'm not mistaken, isn't 18mm over 8 holes - 18/7 spaces
between the 8 holes = approx 2.5x mm ... 0.1" ?

Cheers, I'll look it up.

Shit! Those damn fencepost errors will get you every time!

I tried a plug I had handy which I thought was 0.1", and it didn't fit.
But maybe that one was actually slightly bigger. Feeling a bit stupid
now :)

Thanks,

Pete

So with the proper pitch sorted out, the black one is a fairly standard
Molex Cgrid SL Version A, which I've been able to find and add to my order.

Still stumped on the white one.

On closer inspection, it uses flat "blades" rather than square pins,
which prevents it mating with most normal 0.1" header plugs.

I looked around the JST site for that white one but none look like a
match. Can you put up a picture of the receptacle as well? Sometimes
their shape is distinctive enough to aid in the identification of the
family.

I'm still digging, and have found it looks an awful lot like a Molex
Microblade. Not quite, however - it doesn't have the fillets down the
corners of the receptacle like that does, and more importantly, however
I measure it, I cannot kid myself that mine is 2.00mm pitch. It's
definitely 2.5 or .1".

Thanks,

Pete
