[Elecraft] 50 vs 75 ohm N-connectors

[Jim Price]

Not so.  There is a very real physical difference between 50-ohm and 75-ohm
type N connectors.  The 50-ohm male pins are bigger than the 75-ohm pins and
will damage a 75-ohm female connector.  Likewise if a 75-ohm male is mated
with a 50-ohm female there will not be good electrical contact.

The impedance is a characteristic of the coax cable, not the connector. 
What does matter is what coax cable(s) the N connectors are designed for,
such as RG8, RG58, RG214, etc. Take a look at
http://www.smelectronics.us/typencableconnectors.htm. This might help you
match your connectors to their appropriate cables.
