TE Connectivity lists the 1-2081205-1 as Obsolete. If a pin-compatible replacement is needed, the cable group (RG-178/196) and 50 Ohm impedance are the fixed constraints; verify the mating half interface (SMA threaded) and body finish before substituting. ## What mates and what to check before ordering This SMA jack mates with any standard SMA male plug (threaded coupling, per MIL-STD-348 interface). The nickel-plated zinc body provides RF shielding but is not rated for salt-fog or immersion — keep it inside an enclosure or weatherproof housing.","metaTitle":"TE KOAXXA 1-2081205-1 SMA Jack, 50 Ohm, 18 GHz","metaDescription":"TE 1-2081205-1 SMA jack, 50 Ohm, 18 GHz max, for RG-178/196 cable.
