TNC plug for RG-58 and similar cables — what this kit contains
The TE 5-1814800-3 is a TNC plug, male pin, from the ZDC/Greenpar series — a threaded RF interconnect rated for 50 Ohm systems up to 4 GHz. It ships as a field-termination kit: one connector body, one centre contact, two ferrules, and one sleeve, all in a single bulk pack. The crimp-on shield termination and crimp centre contact make it a standard build for RG-58C, 141A, and Belden 9907 cables. The zinc-alloy body with nickel finish and gold-plated brass centre contact gives 500 mating cycles of reliable service in a free-hanging, in-line mount.
Obsolete — sourcing and cross-reference
This part is officially obsolete. No direct replacement or cross-reference is listed in the TE documentation. If you are evaluating a substitute, the key parameters to match are the TNC threaded interface, 50 Ohm impedance, 4 GHz bandwidth, and the crimp termination for RG-58-class cables.
The kit is designed for RG-58C, 141A, and Belden 9907 — all 50 Ohm cables with a similar dielectric diameter. The crimp ferrules and centre contact are sized for these cables; using a different cable type will require verifying the ferrule inner diameter and the centre-contact pin size.
