Product details

RF Connector for RG-58 and Similar Cables — 50 Ohm, 18 GHz

The 2081205-7: The dielectric is polymethylpentene (PMP). This connector accepts cable groups RG-58, 141, 142, 223, and 400 — a common set for thin coax and semi-rigid lines in test equipment, antenna feeds, and short-run RF interconnects. The shield is terminated by crimp, the center contact by solder.

Lifecycle — Obsolete, Sourced to Order

The 2081205-7 is listed as Obsolete. If a direct replacement is needed, review the TE Connectivity SMA product family for a current-production jack with the same cable-group and impedance profile.

Mating Cycles and Field Service

The gold-on-copper-alloy center contact handles repeated reconnects without significant wear.
