SMA Plug for RG-58 and Similar Coax
The 2081202-7: It terminates with a solder center contact and a crimp shield, using a threaded coupling nut for secure mating.
With a 50 Ohm impedance and a maximum frequency of 18 GHz, this SMA plug supports applications up to the lower Ku band. The cable group compatibility — RG-58, 141, 142, 223, 400 — covers the most common flexible and semi-rigid coax types used in test equipment, antennas, and short-run interconnects. The gold-plated center contact (copper alloy) and nickel-plated zinc body provide corrosion resistance and consistent signal transfer across the rated 500 mating cycles.
Obsolete — Sourcing Reality
The TE 2081202-7 is officially listed as Obsolete. No direct replacement or successor part number is recorded in the lifecycle data. Buyers should evaluate whether a parametric equivalent (same SMA interface, 50 Ohm, 18 GHz, RG-58 cable group) from a current-production series can be qualified, or plan for a last-time buy if stock remains.
