TC-400-716MC 7/16 DIN Male Coaxial Connector - Equivalent & Substitute Parts

Part Overview

The TC-400-716MC is a 7/16 DIN male plug connector manufactured by Amphenol Times Microwave Systems, designed for RF coaxial applications with 50 Ohm impedance. This connector features solder contact termination and clamp shield termination, suitable for free-hanging in-line cable installations. The product is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity and ensure long-term component availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC-400-716MC is determined by strict adherence to the following core parameters:

• Connector style must remain 7/16 DIN
• Connector type must be plug with male pin configuration
• Impedance must be 50 Ohms
• Mounting type must be free hanging (in-line)
• Cable group compatibility with LMR-400
• Fastening type must be threaded
• Operating temperature range must encompass -40°C ~ 85°C
• RoHS compliance status must be maintained

The TC-400-716M-X qualifies as a direct substitute based on these parameters. While secondary characteristics such as shield termination method (clamp versus crimp), center contact material composition, and frequency rating differ, these variations do not preclude functional equivalence within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The TC-400-716M-X is the manufacturer-recommended substitute for the obsolete TC-400-716MC. Both components maintain RoHS compliance and identical moisture sensitivity classification, ensuring regulatory and environmental consistency. The substitute part carries active product status, guaranteeing continued availability and supply chain support.

The TC-400-716M-X demonstrates enhanced frequency capability (6 GHz versus 2 GHz) and improved contact material composition through beryllium copper center contacts with gold plating, providing superior electrical performance characteristics. The shift from clamp to crimp shield termination represents a design evolution within the same connector family. Both parts share identical core specifications: 7/16 DIN style, 50 Ohm impedance, solder contact termination, free-hanging in-line mounting, and LMR-400 cable group compatibility.

Selection of the TC-400-716M-X is appropriate for applications requiring component continuity with the TC-400-716MC, particularly where long-term availability and active manufacturer support are essential.

Frequently Asked Questions (FAQ)

Q: Can the TC-400-716M-X directly replace the TC-400-716MC in existing designs?

A: Yes. Both connectors share identical core electrical and mechanical specifications: 7/16 DIN style, 50 Ohm impedance, solder contact termination, free-hanging in-line mounting, and LMR-400 cable group compatibility. The substitute maintains the same operating temperature range and RoHS compliance status.

Q: What is the primary difference between these two connectors?

A: The main differences are shield termination method (clamp versus crimp), center contact material (brass versus beryllium copper), contact plating (silver versus gold), and maximum frequency rating (2 GHz versus 6 GHz). These variations do not affect functional compatibility for applications within the 2 GHz frequency band.

Q: Why is the TC-400-716MC listed as obsolete?

A: Product obsolescence reflects manufacturer discontinuation. The TC-400-716M-X represents the active equivalent within the Amphenol Times Microwave Systems TC-400 connector series.

Q: Are there packaging differences between these parts?

A: The TC-400-716MC packaging information is not specified in available data. The TC-400-716M-X is supplied in bag packaging.

Q: Do both connectors support the same cable types?

A: Yes. Both connectors are designated for LMR-400 cable group compatibility and maintain identical impedance and mounting specifications.

Q: What certifications apply to both parts?

A: Both the TC-400-716MC and TC-400-716M-X are RoHS compliant, carry ECCN classification EAR99, and share identical HTSUS coding (8536.69.4010). Both maintain Moisture Sensitivity Level 1 (Unlimited).
