Product details

SMA right-angle plug for RG-402 semi-rigid cable

It is a right-angle, in-line free-hanging connector designed for RG-402 (.141" semi-rigid) cable. The interface is 50 Ohm nominal, rated to 18 GHz maximum frequency, making it suitable for microwave signal paths in test equipment, antenna feeds, and RF modules where a compact right-angle launch is needed. The threaded coupling provides vibration-resistant mating per the SMA standard. The centre contact is gold-plated copper alloy, with a nickel-plated zinc body and a silver housing. The contact is solder-terminated; the shield is crimped to the cable braid. The dielectric is polymethylpentene (PMP).

Buyers needing this connector should source through the surplus or broker channel. For a direct replacement, check the TE KOAXXA series for a current-production SMA plug with the same cable group and interface; no pin-compatible cross-reference is documented here.

Cable and termination details

This plug is built specifically for RG-402 (.141" semi-rigid) cable. The centre contact is soldered; the shield is crimped. The package includes the connector body and an end cap (2 pieces total). The right-angle body keeps the cable run parallel to the panel face, saving space in dense RF assemblies.

Frequently asked questions

Where can I purchase 2081203-1 available via RFQ confirmation?

The 2081203-1 is obsolete and not held available via RFQ confirmation. We source it to order against an RFQ through independent distribution — availability and current pricing are confirmed at quote time. Submit a request for your target quantity.

What is the replacement for obsolete 2081203-1?

No official replacement order code is listed by TE Connectivity. The part is in the KOAXXA series; a current-production SMA plug for RG-402 cable from the same series may serve as a functional alternative, but no pin-compatible cross-reference is documented here. Contact TE or a distributor to verify a drop-in substitute.
