TC-500-TM-X TNC Male Plug Crimp Connector Equivalent & Substitute Parts

Part Overview

The TC-500-TM-X is an active TNC male plug crimp connector manufactured by Amphenol Times Microwave Systems, designed for 50 Ohm coaxial cable applications. This connector features solder contact termination with crimp shield termination, rated for LMR-500 cable group with a maximum frequency of 6 GHz. The part is RoHS compliant and currently in active production with 1075 units in stock. Substitute parts may be required due to cable group compatibility, inventory availability, or specific application requirements where alternative cable specifications are acceptable.

Key Parameters

Substitute Part Grouping Explanation

The TC-600-TM-X qualifies as a parametric equivalent substitute based on the following matching electrical and mechanical parameters:

Matching Parameters:

• Connector style: TNC
• Connector type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact termination: Solder
• Shield termination: Crimp
• Mounting type: Free Hanging (In-Line)
• Fastening type: Threaded
• Frequency maximum: 6 GHz
• Operating temperature range: -55°C ~ 125°C
• Mating cycles: 500
• Center contact material: Brass
• Body material: Brass
• Dielectric material: Polytetrafluoroethylene (PTFE)
• Center contact plating: Gold
• Body finish: White Bronze

Differentiating Parameter:

• Cable group: TC-500-TM-X is specified for LMR-500 cable group, while TC-600-TM-X is specified for LMR-600 cable group

The substitution is valid when the application permits use of LMR-600 cable specifications in place of LMR-500.

Parameter Comparison

Engineering Selection Recommendations

Both TC-500-TM-X and TC-600-TM-X are active production parts with current inventory availability. The TC-500-TM-X maintains RoHS compliance, while the TC-600-TM-X meets the more stringent ROHS3 standard. Selection between these parts depends on cable group requirements: TC-500-TM-X for LMR-500 cable applications and TC-600-TM-X for LMR-600 cable applications. Both parts share identical electrical performance characteristics, operating temperature ranges, and mating cycle ratings, making them functionally interchangeable when cable group specifications permit substitution.

Frequently Asked Questions (FAQ)

Q: Can TC-600-TM-X replace TC-500-TM-X in all applications?

A: TC-600-TM-X can replace TC-500-TM-X only when the application design permits use of LMR-600 cable in place of LMR-500 cable. The connectors are electrically and mechanically equivalent for all other parameters.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents a more recent revision of the RoHS directive with updated substance restrictions. TC-600-TM-X meets the newer ROHS3 standard, while TC-500-TM-X meets the earlier RoHS standard. Both are compliant with their respective regulatory requirements.

Q: Are the impedance and frequency ratings identical?

A: Yes. Both parts are rated at 50 Ohms impedance with a maximum frequency of 6 GHz. Electrical performance is equivalent.

Q: What determines substitution eligibility?

A: Substitution is determined by cable group compatibility. The primary difference between these parts is the cable group specification: LMR-500 for TC-500-TM-X and LMR-600 for TC-600-TM-X. All other electrical, mechanical, and environmental parameters are identical.

Q: Are both parts currently available?

A: Yes. TC-500-TM-X has 1075 units in stock and TC-600-TM-X has 1019 units in stock, both in new original condition.
