SMA Connector specification

hey
i am building some RF circuit at 2.4 ghz and want to use SMA connector. Early I used digikey JN02 in my circuit as it was specified in datasheet
http://www.digikey.com/product-detai.../J502-ND/35280
but due to shipping time and problem i have to switch to some other company SMA.
i found a couple but cannot say whether they match specification of previous one .
connector mounting,coaxial termination etc I am all confused.here are the other's i found

can anyone tell which one is identical what does different specification means?
thanks in advance

For use at 2.45 GHz do not worry, most good connectors can be used without problems. SMA is a standard connector usable up to 18 GHz, precision versions over 20 GHz. For PCB mounted versions take care that the PCB is rigid and cannot be bent. Use a minimum amount of solder.
