TC-500-NMC-PL Equivalent & Substitute Parts

Part Overview

The TC-500-NMC-PL is an N-Type connector plug manufactured by Amphenol Times Microwave Systems, designed for 50-ohm coaxial cable applications in RF systems. This connector features a male pin configuration with solder contact termination and clamp shield termination, suitable for free-hanging in-line mounting. The product is classified as obsolete, necessitating identification of active equivalent parts to maintain system compatibility and ensure continued availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC-500-NMC-PL is determined by the following critical parameters that must remain constant or be compatible:

Mandatory Compatibility Parameters:

• Connector Style: N Type (maintains mechanical and electrical interface)
• Connector Type: Plug, Male Pin (preserves mating interface)
• Impedance: 50 Ohms (ensures signal integrity)
• Contact Termination: Solder (maintains electrical connection method)
• Cable Group: LMR-500 (ensures proper cable fit and performance)
• Fastening Type: Threaded (preserves mechanical coupling)

Allowable Variation Parameters:

• Shield Termination: May vary from clamp to crimp (both provide equivalent shielding performance)
• Mounting Type: May include right-angle orientation in addition to in-line (functional variation)
• Frequency - Max: May exceed 2.5 GHz (backward compatible)
• Operating Temperature Range: May exceed -5°C ~ 75°C (backward compatible)

The substitute part TC-500-NMH-X meets all mandatory compatibility requirements while offering enhanced specifications in frequency response and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The TC-500-NMH-X is the manufacturer-recommended substitute for the obsolete TC-500-NMC-PL. Both parts maintain identical core specifications for N-Type connector style, male pin configuration, 50-ohm impedance, solder contact termination, and LMR-500 cable compatibility.

The TC-500-NMH-X offers enhanced performance characteristics including extended frequency response (6 GHz versus 2.5 GHz) and expanded operating temperature range (-40°C ~ 125°C versus -5°C ~ 75°C). The shift from clamp to crimp shield termination provides equivalent shielding performance with alternative mechanical implementation. Both parts are RoHS compliant and manufactured by the same supplier, ensuring consistent quality and reliability standards.

For applications requiring the original in-line orientation exclusively, verify that the right-angle mounting option in the TC-500-NMH-X does not conflict with system layout requirements, as this represents an additional capability rather than a replacement of the in-line configuration.

Frequently Asked Questions (FAQ)

Q: Can TC-500-NMH-X directly replace TC-500-NMC-PL in existing assemblies?

A: Yes. Both connectors maintain identical N-Type connector style, male pin configuration, 50-ohm impedance, solder termination, and LMR-500 cable compatibility. The primary difference is shield termination method (clamp versus crimp), which does not affect electrical performance or mechanical fit.

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

A: Both termination methods provide equivalent shielding performance. Clamp termination uses a mechanical clamping mechanism, while crimp termination uses a compressed connection. The choice depends on assembly process and equipment availability.

Q: Does the TC-500-NMH-X support right-angle mounting?

A: The TC-500-NMH-X is specified for both free-hanging in-line and right-angle mounting configurations. Systems requiring only in-line orientation can use the in-line configuration without impact.

Q: Are there frequency or temperature limitations when substituting?

A: No. The TC-500-NMH-X exceeds the original specifications in both frequency response (6 GHz versus 2.5 GHz) and operating temperature range (-40°C ~ 125°C versus -5°C ~ 75°C), making it suitable for applications with equal or less demanding requirements.

Q: What packaging is available for the TC-500-NMH-X?

A: The TC-500-NMH-X is supplied in bag packaging, suitable for component-level procurement and assembly operations.

Q: Are both parts RoHS compliant?

A: Yes. Both TC-500-NMC-PL and TC-500-NMH-X are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
