What does the suffixed (NSA) on the JMC series recepatacles indicate?

The (NSA) indicates a modification made to the guide ribs of the receptacle to help prevent breakage during accidental, slantwise mating cycles instead of the proper straight mating method as well as the inclusion of a Nickel stripe to help prevent solder from traveling up the contact during the reflow process.
