TC-600-NMC Equivalent & Substitute Parts

Part Overview

The TC-600-NMC is an N-type male plug connector manufactured by Amphenol Times Microwave Systems, designed for 50-ohm coaxial cable applications with solder termination and clamp shield connection. This connector is rated for operation up to 6 GHz and supports the LMR-600 cable group with free-hanging in-line mounting.

The TC-600-NMC is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring N-type male plug connectors with comparable electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the TC-600-NMC with the TC-600-NMH-X is based on equivalence in the following critical parameters:

Connector Style & Type: Both are N-type male plug connectors
Impedance: Both maintain 50-ohm impedance
Mounting Configuration: Both support free-hanging in-line mounting
Cable Compatibility: Both support the LMR-600 cable group
Frequency Rating: Both rated to 6 GHz maximum
Fastening: Both use threaded fastening
Core Materials: Both use brass body and center contact with gold plating
Dielectric: Both use PTFE dielectric material

The primary differences between these parts are the contact termination method (solder versus push-on crimp) and shield termination approach (clamp versus crimp), which represent functional variations within the same connector family rather than incompatibilities.

Engineering Selection Recommendations

The TC-600-NMH-X is the manufacturer-recommended substitute for the obsolete TC-600-NMC. Both connectors maintain electrical equivalence at 50 ohms and 6 GHz maximum frequency, with identical mechanical mounting and cable group compatibility.

The TC-600-NMH-X offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. Both parts meet RoHS compliance requirements, with the substitute meeting the more recent ROHS3 standard.

Selection between these parts depends on termination method requirements: the TC-600-NMC uses solder termination with clamp shield connection, while the TC-600-NMH-X uses push-on crimp termination. The operating temperature range of the TC-600-NMC (-65°C to 165°C) is wider than the TC-600-NMH-X (-55°C to 155°C), which may be a consideration for extreme temperature applications.

Frequently Asked Questions (FAQ)

Q: Can the TC-600-NMH-X directly replace the TC-600-NMC in existing applications?

A: Electrical and mechanical compatibility is maintained. The primary consideration is the termination method: the TC-600-NMC requires solder termination while the TC-600-NMH-X uses push-on crimp termination. Cable preparation and assembly procedures will differ accordingly.

Q: Are there impedance or frequency differences between these connectors?

A: No. Both connectors maintain 50-ohm impedance and are rated to 6 GHz maximum frequency. They are electrically equivalent for RF applications within this specification range.

Q: What is the significance of the different body finishes (Silver vs. White Bronze)?

A: Body finish differences do not affect electrical performance. Both finishes provide corrosion protection and are suitable for standard operating environments. The choice between them is typically driven by application-specific requirements or inventory availability.

Q: Does the operating temperature range difference affect substitution suitability?

A: The TC-600-NMC supports a wider temperature range (-65°C to 165°C) compared to the TC-600-NMH-X (-55°C to 155°C). Applications requiring operation below -55°C or above 155°C should retain the TC-600-NMC if available, or evaluate alternative connector families.

Q: Are both parts RoHS compliant?

A: Yes. The TC-600-NMC is RoHS Compliant, and the TC-600-NMH-X meets the ROHS3 standard, which represents a more recent iteration of RoHS requirements.

Q: What does the insertion loss specification of 0.1 dB for the TC-600-NMH-X indicate?

A: The 0.1 dB insertion loss specification for the TC-600-NMH-X represents the signal attenuation introduced by the connector at RF frequencies. This specification is not provided for the TC-600-NMC in the available data.
