TC-240-NF-PM-X Equivalent & Substitute Parts

Part Overview

The TC-240-NF-PM-X is an N-type coaxial connector jack (female socket) manufactured by Amphenol Times Microwave Systems. This panel-mount connector features solder contact termination and crimp shield termination, designed for 50-ohm RF applications up to 6 GHz. The product is classified as obsolete, necessitating identification of active equivalent components that maintain electrical and mechanical compatibility for continued system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC-240-NF-PM-X requires evaluation of the following critical parameters:

Electrical Compatibility:

• Impedance: 50 Ohms (mandatory match)
• Frequency range: Maximum 6 GHz or higher
• Cable group: LMR-240 compatibility

Mechanical Compatibility:

• Connector style and type must support the same mating interface
• Contact termination method must be compatible with system assembly requirements
• Operating temperature range must encompass application requirements

Compliance & Status:

• RoHS compliance status
• Product availability and active manufacturing status

The identified substitute EZ-240-SM-RA-X shares the same cable group (LMR-240), impedance (50 Ohms), frequency capability (6 GHz), and RoHS compliance. However, this substitute represents a different connector style (SMA vs. N-type) and mounting configuration (right-angle free-hanging vs. panel-mount), requiring mechanical interface verification before implementation.

Parameter Comparison

Engineering Selection Recommendations

The EZ-240-SM-RA-X is an active product with current manufacturing status and RoHS compliance, addressing the obsolescence of the TC-240-NF-PM-X. Both components share identical impedance (50 Ohms), cable group (LMR-240), and maximum frequency (6 GHz) specifications.

Selection of this substitute requires verification of the following system-level factors:

• Mechanical interface compatibility: The substitute uses SMA connector style with right-angle free-hanging configuration versus the original N-type panel-mount design. Physical mounting and mating interface must be confirmed.
• Operating temperature range: The substitute operates within -40°C to 85°C, which is narrower than the original -65°C to 165°C range. Application temperature requirements must be validated.
• Contact termination: The substitute uses push-on termination versus solder termination on the original. Assembly process compatibility must be assessed.

Frequently Asked Questions (FAQ)

Q: Can the EZ-240-SM-RA-X directly replace the TC-240-NF-PM-X?

A: Direct mechanical replacement is not possible due to different connector styles (SMA vs. N-type) and mounting configurations (right-angle free-hanging vs. panel-mount). System redesign or adapter solutions may be required.

Q: Are the electrical specifications compatible?

A: Yes. Both components operate at 50 ohms impedance, support LMR-240 cable group, and function to 6 GHz maximum frequency.

Q: What is the operating temperature difference?

A: The TC-240-NF-PM-X operates from -65°C to 165°C, while the EZ-240-SM-RA-X operates from -40°C to 85°C. Applications requiring the full original temperature range cannot use this substitute without thermal management verification.

Q: Why is the original part obsolete?

A: The TC-240-NF-PM-X is classified as obsolete by the manufacturer. The EZ-240-SM-RA-X represents an active alternative within the same product family, offering continued availability and manufacturing support.

Q: What termination method differences exist?

A: The original uses solder contact termination, while the substitute uses push-on termination. This affects assembly procedures and may require process modification.
