Rated to 18 GHz, this connector suits RF test points, instrumentation front-ends, and board-level coax transitions where the SMA threaded coupling provides vibration-resistant retention. ## Sourcing and Replacement Planning The 2081233-1 is listed as Obsolete. For BOM positions that still require this exact footprint and interface, the available channel is surplus or broker inventory sourced per RFQ. If a design-in is still open, a parametric review against current-production SMA jacks from the same series or a compatible 50 Ohm through-hole variant is the practical next step. ## What the 18 GHz and 500-Cycle Ratings Mean The 18 GHz maximum frequency means this jack maintains a 50 Ohm impedance through the launch up to that band — above it the VSWR rises and the signal path degrades. For sub-6 GHz work (cellular, ISM, GNSS) the margin is generous. The 500 mating cycles come from the gold-on-copper alloy center contact and the threaded coupling, which avoids the wear of a push-pull mechanism. That cycle life is enough for a test-port connector that sees weekly reconnects, not daily production-line mating.","metaTitle":"TE KOAXXA 2081233-1 SMA Jack, 50 Ohm, 18 GHz","metaDescription":"TE Connectivity KOAXXA 2081233-1 SMA jack, 50 Ohm, 18 GHz max, through-hole, gold-plated center contact.
