Product details

The Amphenol 202101-10 is a protective cap (cover) for TNC connectors, specifically designed to fit over TNC jacks. It's a brass body with a nickel finish — the same base metal and plating you'd see on a standard TNC connector body, so galvanic compatibility with the mating jack isn't an issue. The cap is unsealed (no IP67 rating like the 202101-13 or 202101-12 siblings), so it's a dust cover for bench or indoor panel use, not a waterproof cap for outdoor or washdown environments.

Does It Fit All TNC Jacks?

This cap is specified for use with TNC jacks — the threaded-coupling RF interface. The thread form and coupling nut diameter match the TNC standard, so it will fit any standard TNC jack (male or female, depending on the cap orientation). It won't fit BNC, SMA, N-type, or other RF interfaces. If you need a cap for a TNC plug (the cable-end male), this isn't the part — the 202101 series covers jacks only.

Frequently asked questions

What is the 202101-10 cap used for?

It's a protective dust cover for TNC jacks. Slips over the threaded interface to keep debris, moisture, and physical damage off the centre pin and dielectric when the connector is unmated.

Does 202101-10 fit all TNC jacks?

Yes, it's designed for standard TNC jacks. The thread and coupling dimensions follow the TNC interface spec, so it fits any TNC jack — bulkhead, panel-mount, or PCB-mount — as long as the jack's outer thread is accessible.
