Product details

What This TNC Plug Kit Covers

The Amphenol RF 031-2315 is a TNC plug kit — a threaded, 50 Ohm RF connector designed for field-termination on small-diameter coaxial cables. The kit includes the plug body, a gold-plated brass centre pin, a crimp ferrule, and a PTFE dielectric sleeve, all in one order code. The threaded coupling (not bayonet) gives a positive mechanical lock — the TNC interface is essentially a threaded version of the BNC, offering better vibration resistance and a higher frequency ceiling.

This kit is dimensioned for RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 — all roughly 0.110-inch-diameter coax with a solid or stranded centre conductor. The crimp-style shield termination and contact termination mean you need a crimp tool with the correct hex die for the ferrule and centre pin.

Frequently asked questions

Where can I buy the Amphenol RF 031-2315 and how do I get a price?

Submit a request for quote (RFQ) with your target quantity, and we will confirm current pricing and availability.

What is the impedance of Amphenol RF 031-2315?

The 031-2315 is a 50 Ohm connector. This is the standard impedance for most RF test, telecom, and antenna systems — match it with 50 Ohm cable and 50 Ohm TNC jacks to avoid return-loss penalties.

What cable does the 031-2315 fit?

The kit is designed for RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 cables. These are all approximately 0.110-inch-diameter coax with a 50 Ohm characteristic impedance.

Does the 031-2315 connector kit include all necessary parts?

Yes — the kit contains four pieces: one TNC plug body, one centre contact (gold-plated brass pin), one crimp ferrule, and one PTFE dielectric sleeve. You will still need the correct crimp tool for the centre pin and shield ferrule.

Is the 031-2315 connector threaded or bayonet?

Threaded. The TNC interface uses a threaded coupling nut, not a bayonet lock. This gives a more vibration-resistant connection than a standard BNC.
