SMA versus RP-SMAThe center contact matters as well as the threaded outer shell.N-Type versus RP-N-TypeIs the center-contact convention standard N-Type or reverse-polarity N-Type? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.TNC versus RP-TNCIs the threaded TNC interface standard or reverse polarity? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.MCX versus MMCXWhich miniature snap-on coaxial family matches the documented component? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.BNC versus Mini-BNC versus HD-BNCWhich bayonet/coaxial interface family is actually documented for the equipment? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.LEMO broadcast 75-ohm versus 00 NIM-CAMAC 50-ohm triaxIs the documented interface a 75-ohm broadcast triax form or the 50-ohm LEMO 00 NIM-CAMAC form? Impedance and series identity are not interchangeable.BNC vs TNC coaxial connectorsBNC uses bayonet coupling while TNC uses threaded coupling. Connector family, impedance and application still need to be verified independently.
