TNC Plug for RG-174/188/316 — What This Connector Is
The TE Connectivity 1-1337611-0 is a TNC plug, male pin, from the Greenpar series. The centre contact is soldered, and the shield is crimped through the ferrule.
Cable Build and Termination Sequence
This connector is designed for a specific cable group: RG-174A, RG-188A, and RG-316. These are small-diameter 50 Ohm coax cables common in test leads, antenna feeds, and internal RF jumpers.
Obsolete — Sourcing and Cross-Reference Reality
The 1-1337611-0 is listed as Obsolete. For a form-fit-function cross-reference, the buyer needs to match the TNC plug interface, 50 Ohm impedance, 11 GHz bandwidth, solder pin, and crimp shield termination for RG-174/188/316 cable. Confirm the cable group and interface before substituting.
The 11 GHz max frequency means it covers the L, S, and C bands, and the lower portion of the X band; above 11 GHz, the VSWR and insertion loss degrade. The 0.2 dB insertion loss is low for a TNC plug at these frequencies, indicating a well-controlled interface.
