The body is nickel-plated brass, the center contacts are brass with tin plating, and the dielectric uses polyoxymethylene (POM) acetal and polypropylene (PP). ## Dual Retention: Snap-On and Threaded The fastening type is both Snap-On and Threaded — the F plug side threads onto an F jack for a vibration-resistant connection, while the F jack side accepts a snap-on F plug for quick field mating. This dual retention is common on F-type adapters used in drop cables where the threaded side secures to a wall plate or splitter and the snap-on side connects to the customer-premises equipment. ## Free-Hanging Inline Mount The adapter is free hanging (in-line) — no panel cutout, no bracket. It sits between two cables as a barrel splice. That means Amphenol RF is not actively supporting this part for new projects, though existing designs may still be serviced. For a new BOM line, you will want to evaluate a current-production 75 Ohm F-type adapter — the same series base number 222157 may have active variants, or an alternative from the same family. ## Sourcing for Legacy and Bridge Builds Because this part is NRND, it is not sitting on a distributor shelf in volume. We source it through independent distribution channels against your RFQ — the lead time and price depend on the remaining factory stock and broker availability at the time of your request. If you need a drop-in replacement for a new design, the matching F-type adapter in the same series with an active lifecycle would be the better choice; we can help identify that alternative when you send your BOM.","metaTitle":"222157-12 Amphenol RF F to F Adapter, 75 Ohm, 2 GHz, NRND","metaDescription":"Amphenol RF 222157-12 F-type plug-to-jack adapter, 75 Ohm impedance, 2 GHz max frequency, straight in-line body.
