Edit Reason: Change Purpose of thread!

EDIT: I'm changing the purpose of this thread to become a list of SMA connectors reported to work with System Blue main board. Please submit your full info for part and source as post to this thread. Thanks!
TE Connectivity Part# 5-1814832-1 / Farnell Part# 1248990 / Newark Part# 13M4002 --- Description: "5-1814832-1 - RF / Coaxial Connector, SMA Coaxial, Straight Jack, Solder, 50 ohm, Beryllium Copper:"
-- Reported by "allsorts" and "Andrew.Instone-Cowie"

Original Post:
So, no idea what possessed me NOT to buy the SMA connectors when I bought the station. Guess I thought that buying them from a supply house over here would not be that difficult. So far, I own 8 SMA connectors that won't fit the board... connector housing pins are too large to fit through the PCB holes...
And these were NICE Cinch connectors too....
Do I really have to buy the LPRS from the UK or settle for cheap Chinese UXCELL connectors that don't even have a board standoff ledge on the legs...
I'd really prefer the next batch work and be quality parts... at least a little better anyway.

I have NOT been able to find a standard for SMA PCB Connectors - Do not think it exists because it can not comply with specs for 18GHz
For monitoring we chose a small plug that was suitable for coax - SMA suited us well and could be cheap.
I do not know where Egon buys connectors - A German supplyer I suppose.
I find mine on eBay at very low prices - NO one have failed so far (7-9-13)

Definitely NOT a trivial exercise... I bought some Johnson- Cinch Connectivity connectors whose drawing indicated were 0.040" legs and 0.200" pitch, which SHOULD have fit....
They did NOT fit... legs too big... Turns out the diameter is actually approximately 0.059"!!!
So I tried to order the LPRS part and pay the extra $20 freight from the UK.... showed 100 in stock... 25 October ship date... apparently someone else bought all Farnell had and the US stock level indicator hadn't "caught up".
I am now trying yet another part... Multicomp made, 0.040" leg and 0.201" pitch according to the drawing...
There should be a STRONG WARNING that says, buy from us if you want these, because it's a Royal Pain in the Arse to "Do It Yourself" for this part.

I bought and fitted Farnell (Newark) part 1248990 "5-1814832-1 - RF / Coaxial Connector, SMA Coaxial, Straight Jack, Solder, 50 ohm, Beryllium Copper" from TE Connectivity. Maybe you can find a US supplier with that part? Newark want USD1.58 but with USD20.00 shipping from the UK surcharge.
Digikey USD2.34
Mouser USD1.58
US Shipping still seems to be excessive, most mail order places in the UK offer free delivery if you spend from £5 to £50 (depends on the company). Farnell offer free next day delivery if you spend over £20 nett.
Cheers
Dave.

Thank you gentlemen...
Turns out that Element 14 was WRONG, and the LPRS part IS in stock at Farnell... <grrrr>
Of course I didn't learn that until AFTER I submitted the order for the Multicomp part: Newark #82K9793 Mfr.# SPC20113, brass $2.53 per piece, but only $5 shipping.
Perhaps we can make some lemonade out of lemons here and put together a list of compatible parts... I'll post back once I test them...

To be honest it never occurred to me that they would not be a standard fitment, so I guess I got lucky!

No idea... Can't really add it to the list since neither has a manufacturer or a part # associated... One from Australia and one from China...
In any event, I ordered the LPRS part from the UK, via Newark.... Lord help me. Supposed to maybe have 100, maybe not. Farnell says 918 more in stock on 27 August... Newark says not in stock until 30 October... Who knows at this point.
I ordered 24, so I could rescue the next two folks in the US....

They do have some specifications listed in the description if that is helpful.

FINALLY got 24 each of the specified LPRS connectors from Farnell via Newark Element 14.... 8 installed and 16 "in the bank" just in case.... and hopefully for my second Blue to put in a different location.
