Key Parameters

Substitute Part Grouping Explanation

The TC-240-NMH-X qualifies as a manufacturer-recommended substitute based on the following alignment of critical parameters:

Matching Parameters:

• Connector Style: N Type
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Solder
• Mounting Type: Free Hanging (In-Line)
• Cable Group: LMR-240
• Fastening Type: Threaded
• Operating Temperature: -65°C ~ 165°C
• Body Material: Brass
• Center Contact Material: Brass
• Dielectric Material: Polytetrafluoroethylene (PTFE)

Differing Parameters:

• Shield Termination: Crimp (substitute) vs. Clamp (original)
• Frequency - Max: 6 GHz (substitute) vs. 11 GHz (original)
• Body Finish: White Bronze (substitute) vs. Silver (original)
• Product Status: Active (substitute) vs. Obsolete (original)

The substitute maintains functional compatibility for LMR-240 cable applications within the specified frequency and temperature ranges of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The TC-240-NMH-X is the manufacturer-recommended substitute for the obsolete TC-240-NMC. Both parts maintain RoHS compliance and share identical operating temperature ranges and core material specifications. The substitute is currently in active production status, ensuring availability for procurement and inventory replenishment.

Selection of the TC-240-NMH-X requires consideration of the frequency specification difference: the substitute operates to 6 GHz maximum, compared to the original part's 11 GHz maximum. Applications operating below 6 GHz are fully compatible. The shield termination method differs (crimp versus clamp), which affects installation methodology but does not alter electrical performance for the specified cable group.

Frequently Asked Questions (FAQ)

Q: Can TC-240-NMH-X directly replace TC-240-NMC in all applications?

A: The TC-240-NMH-X is compatible with applications operating at frequencies up to 6 GHz. If your system operates above 6 GHz, the frequency specification of the substitute must be evaluated against your application requirements. Both parts are rated for LMR-240 cable and maintain identical impedance and temperature specifications.

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

A: Clamp termination (TC-240-NMC) uses a mechanical clamping mechanism for shield attachment. Crimp termination (TC-240-NMH-X) requires a crimping tool for shield attachment. The electrical performance is equivalent for the specified cable group; the difference is in installation methodology.

Q: Why is TC-240-NMC listed as obsolete?

A: The TC-240-NMC has been discontinued by the manufacturer. The TC-240-NMH-X represents the active production equivalent, ensuring continued availability and support for new designs and replacements.

Q: Are there packaging differences between these parts?

A: TC-240-NMC packaging information is not specified in available data. TC-240-NMH-X is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet current compliance standards?

A: TC-240-NMC is RoHS Compliant. TC-240-NMH-X is ROHS3 Compliant, representing the current regulatory standard. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification.
