Product details

The TE Connectivity 221500-1 is a TNC to TNC adapter — a straight, same-series barrel that joins two TNC jacks (female to female) in a single signal path. It is a bulkhead-mount panel adapter, built to pass an RF signal through a chassis wall without breaking the 50 Ohm impedance. Each unit ships with the connector, a lockwasher, and a nut for panel installation.

Sourcing and Lifecycle — What the Obsolete Status Means

The 221500-1 is listed as Obsolete.

Mating and Installation

Both ends are TNC jacks with threaded coupling, so the adapter mates with any TNC plug (male) on either side. The straight body keeps the signal path in line with the panel — the bulkhead flange seats against the panel face, and the included lockwasher and nut secure it from the opposite side.

Frequently asked questions

What is the impedance of the 221500-1?

The 221500-1 is a 50 Ohm impedance adapter, which matches the standard characteristic impedance for TNC interfaces used in RF and telecommunications equipment.
