Product details

Obsolete — 2081204-9 SMA Jack for RG-405

The gold-plated center contact handles 500 mating cycles, and the nickel-plated zinc body with threaded fastening provides a secure panel mount via the front-side nut.

Specifications and Fit for RG-405

The 2081204-9 is purpose-built for RG-405 (.085" semi-rigid) cable. The shield termination is crimp, and the center contact is solder — a common field-termination method for semi-rigid coax. The 50 Ohm impedance and 18 GHz frequency max mean this jack supports signals up to the Ku-band without significant mismatch loss. The dielectric material is polymethylpentene (PMP), chosen for stable RF performance across the temperature range.

The 2081204-9 is officially obsolete. For a current-production alternative, look for a TE SMA jack with the same RG-405 cable group, 50 Ohm impedance, and panel-mount bulkhead feature — the KOAXXA series may have an active variant, but verify the interface dimensions and mating cycle rating against your BOM.

Frequently asked questions

Where can I buy the 2081204-9 available via RFQ confirmation?

The 2081204-9 is obsolete and not held available via RFQ confirmation by the manufacturer.

Is the 2081204-9 obsolete and what is the replacement?

Yes, the 2081204-9 is obsolete. TE Connectivity does not list a direct replacement for this exact order code. For a current-production alternative, look for a TE SMA jack with the same RG-405 cable group, 50 Ohm impedance, and panel-mount bulkhead feature — verify the interface dimensions and mating cycle rating against your BOM before specifying.

Does the 2081204-9 work with RG-405 cable?

Yes, the 2081204-9 is specifically designed for RG-405 (.085" semi-rigid) cable. It uses a crimp shield termination and solder center contact, which is the standard termination method for this cable type.
