TC-600-716MC 7/16 DIN Male Clamp Connector - Equivalent & Substitute Parts

Part Overview

The TC-600-716MC is a 7/16 DIN male plug connector manufactured by Amphenol Times Microwave Systems, designed for coaxial RF applications with 50 Ohm impedance. This connector features solder contact termination and clamp shield termination, rated for operation up to 2.5 GHz with a maximum voltage of 2700 V. The product is currently listed as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new designs requiring compatible RF connectivity solutions.

Substitute Part Grouping Explanation

Substitution eligibility for the TC-600-716MC is determined by the following critical parameters:

Connector Style & Type: Must be 7/16 DIN male plug to ensure mechanical and electrical compatibility with existing mating connectors
Impedance: Must maintain 50 Ohm impedance for RF signal integrity
Contact Termination: Solder termination is required for cable attachment compatibility
Mounting Configuration: Free hanging (in-line) mounting type must be preserved
Cable Group: LMR-600 cable compatibility must be maintained
Electrical Ratings: Operating temperature range and voltage rating must meet or exceed the original specification

The TC-600-716M-X qualifies as a substitute based on these parameters. While it introduces differences in shield termination method (crimp vs. clamp) and enhanced frequency capability (6 GHz vs. 2.5 GHz), these represent improvements that do not compromise backward compatibility with systems designed for the TC-600-716MC.

Engineering Selection Recommendations

The TC-600-716M-X is the manufacturer-recommended substitute for the obsolete TC-600-716MC. Both connectors maintain identical core RF specifications: 7/16 DIN male plug configuration, 50 Ohm impedance, solder contact termination, and LMR-600 cable compatibility. Both are RoHS compliant and operate across the same temperature range (-40°C to 85°C).

The TC-600-716M-X offers extended frequency capability (6 GHz vs. 2.5 GHz) and improved ingress protection (IP67 rating), representing a performance enhancement suitable for applications originally designed for the TC-600-716MC. The shift from clamp to crimp shield termination does not affect mechanical or electrical compatibility with standard 7/16 DIN mating connectors.

Selection of the TC-600-716M-X is appropriate for new designs and replacement applications where the original TC-600-716MC is no longer available. The active product status of the substitute ensures ongoing supply chain availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the TC-600-716M-X directly replace the TC-600-716MC in existing installations?

A: Yes. Both connectors share identical 7/16 DIN male plug configuration, 50 Ohm impedance, solder termination, and LMR-600 cable compatibility. The mechanical interface with mating connectors remains unchanged.

Q: What is the difference between clamp and crimp shield termination?

A: Clamp termination (TC-600-716MC) uses a mechanical clamping mechanism to secure the shield. Crimp termination (TC-600-716M-X) uses a crimped connection. Both methods provide equivalent electrical shielding performance for 50 Ohm RF applications.

Q: Does the higher frequency rating of the TC-600-716M-X affect compatibility?

A: No. The 6 GHz maximum frequency of the TC-600-716M-X exceeds the 2.5 GHz specification of the TC-600-716MC. Systems designed for 2.5 GHz operation remain fully compatible, as the substitute connector supports all frequencies within the original operating range.

Q: Are both connectors RoHS compliant?

A: Yes. Both the TC-600-716MC and TC-600-716M-X are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What packaging is available for the TC-600-716M-X?

A: The TC-600-716M-X is supplied in bag packaging, suitable for component integration into assembly processes.
