Product details

The TE Connectivity KOAXXA 2081205-1 is an SMA jack, female socket, designed for RG-402 (.141" semi-rigid) cable. The threaded coupling and crimp shield termination give a stable, repeatable RF connection for test equipment, microwave modules, and antenna feeds where the cable run is fixed after assembly.

For a BOM that requires this exact SMA jack, the procurement path is the surplus and broker channel; there is no direct factory replenishment.

The body is zinc with nickel finish, the centre contact is copper alloy with gold plating. The dielectric is polymethylpentene (PMP). Termination is solder for the centre contact and crimp for the shield — a standard build for semi-rigid coax where the centre conductor is soldered and the braid is crimped into the ferrule. The free-hanging, in-line mounting with threaded fastening means it mates to a bulkhead jack or panel-mount receptacle and stays put under vibration.

Rated for 500 mating cycles — a solid figure for an SMA connector, indicating the gold-plated centre contact and nickel-plated body will tolerate repeated connect/disconnect in test or field-service scenarios without significant degradation.

Frequently asked questions

Where can I buy 2081205-1 and what is the price?

Contact the storefront with your BOM quantity for a same-day quote.

What is the replacement or alternative for 2081205-1?

No official successor or cross-reference is recorded for the 2081205-1. For a pin-compatible alternative in the KOAXXA series, a parametric search on SMA jack, 50 Ohm, 18 GHz, for RG-402 cable is the next step — confirm the mechanical footprint and thread type before substituting.

What cable is 2081205-1 designed for?

The 2081205-1 is designed for RG-402 (.141" semi-rigid) coax cable. The crimp shield termination and solder centre contact match the construction of that cable type.

What is the frequency rating of 2081205-1?

The 2081205-1 is rated to 18 GHz maximum frequency at 50 Ohm impedance — the full bandwidth of the SMA connector interface.
