The shield termination method (crimp) gives a reliable, repeatable ground connection without the risk of cold solder joints on the braid. The contact is included in the package (2 pieces: 1 connector, 1 contact). For field installation, the crimp shield termination is faster than a solder-braid approach and produces consistent pull-off strength. No official replacement part number is on record from the manufacturer. If a direct drop-in replacement is required, a cross-reference search against the KOAXXA series or a parametric search for SMA jacks with the same cable group (RG-405.085\") and 50 Ohm impedance is the practical next step — but no pin-compatible alternate is documented here. The 335 V voltage rating and 500-cycle mating life are both in line with standard SMA construction. The gold center contact plating is the right choice for low intermodulation and corrosion resistance in repeated-mate scenarios. The body finish (nickel over zinc) is typical for indoor or protected-environment SMA connectors; if the application sees salt spray or outdoor exposure, a stainless-steel body variant would be preferred.","metaTitle":"2081205-9 TE KOAXXA SMA Jack, 50 Ohm, 18 GHz, Obsolete","metaDescription":"2081205-9 TE KOAXXA SMA jack, 50 Ohm, 18 GHz max, for RG-405 .085\" semi-rigid cable.
