F-Type Inline Adapter — 75 Ohm, 2 GHz, Straight Body
The Amphenol RF 222157-12 is a straight F-type adapter that converts an F jack (female socket) to an F plug (male pin), letting you join two F-type cables end-to-end or adapt a panel jack to a cable end. 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.
