TC-400-NFC-BH Equivalent & Substitute Parts

Part Overview

The TC-400-NFC-BH is an N-type female jack connector designed for panel mount applications with bulkhead configuration. This connector features 50-ohm impedance, solder termination, and clamp shield termination, suitable for LMR-400 cable integration. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for continued system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TC-400-NFC-BH is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria (Must Match):

• Connector Style: N Type
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder
• Cable Group: LMR-400
• Fastening Type: Threaded

Secondary Substitution Criteria (Allowable Variations):

• Mounting Type: Panel Mount variants or free-hanging configurations with equivalent electrical performance
• Shield Termination: Clamp or crimp termination, provided impedance and frequency specifications are maintained
• Frequency - Max: Must support minimum 6 GHz; higher frequency ratings are acceptable
• Operating Temperature: Must encompass or exceed the original range where feasible
• Product Status: Active parts are preferred for obsolete originals

Non-Substitutable Parameters:

• Connector style and gender (N-type female jack is specific)
• Impedance (50 ohms is mandatory)
• Cable compatibility (LMR-400 group)

Parameter Comparison

Engineering Selection Recommendations

TC-400-NFC-BH-A (Parametric Equivalent): This part is the direct active replacement for the obsolete TC-400-NFC-BH. It maintains identical electrical specifications (50 ohms, 11 GHz maximum frequency), mechanical configuration (panel mount bulkhead), and material composition (beryllium copper center contact, white bronze finish). Both parts are RoHS compliant and support the same operating temperature range (-65°C ~ 165°C). The TC-400-NFC-BH-A is manufactured by Amphenol Times Microwave Systems and carries active product status with 500 mating cycles specification. This part is the primary selection for direct replacement in existing designs.

TC-400-NF-X (MFR Recommended): This connector is an alternative from Times Microwave Systems suitable for applications where free-hanging (in-line) mounting is acceptable instead of panel mount bulkhead configuration. The TC-400-NF-X operates at a maximum frequency of 6 GHz, which is lower than the original 11 GHz specification. The operating temperature range (-55°C ~ 155°C) is narrower than the original part. This connector features crimp shield termination rather than clamp termination and uses standard copper center contact instead of beryllium copper. The TC-400-NF-X is ROHS3 compliant and provides 0.1 dB insertion loss specification. Selection of this part requires confirmation that the reduced frequency capability and different mounting configuration are compatible with system requirements.

Frequently Asked Questions (FAQ)

Q: Can TC-400-NFC-BH-A be used as a direct replacement for TC-400-NFC-BH?

A: Yes. The TC-400-NFC-BH-A is electrically and mechanically equivalent to the obsolete TC-400-NFC-BH. Both connectors maintain 50-ohm impedance, 11 GHz maximum frequency, panel mount bulkhead configuration, solder contact termination, and clamp shield termination. The TC-400-NFC-BH-A is the active production equivalent.

Q: What is the primary difference between TC-400-NFC-BH-A and TC-400-NF-X?

A: The TC-400-NFC-BH-A is a panel mount bulkhead connector with 11 GHz maximum frequency and clamp shield termination. The TC-400-NF-X is a free-hanging (in-line) connector with 6 GHz maximum frequency and crimp shield termination. Selection depends on whether the application requires panel mount bulkhead configuration and supports the 6 GHz frequency limitation.

Q: Are both substitute parts RoHS compliant?

A: Yes. TC-400-NFC-BH-A is RoHS compliant. TC-400-NF-X is ROHS3 compliant. Both meet current environmental compliance requirements.

Q: What is the operating temperature difference between the main part and TC-400-NF-X?

A: The TC-400-NFC-BH operates from -65°C to 165°C. The TC-400-NF-X operates from -55°C to 155°C. Applications requiring operation below -55°C or above 155°C must use TC-400-NFC-BH-A or the original part.

Q: Does TC-400-NF-X provide insertion loss specification?

A: Yes. TC-400-NF-X specifies 0.1 dB insertion loss. The original TC-400-NFC-BH and TC-400-NFC-BH-A do not provide insertion loss data in available documentation.

Q: Can TC-400-NF-X be used in panel mount applications?

A: No. TC-400-NF-X is configured for free-hanging (in-line) mounting and does not include bulkhead panel mount features. Applications requiring panel mount configuration must use TC-400-NFC-BH-A.

Q: What is the center contact material difference between the parts?

A: TC-400-NFC-BH and TC-400-NFC-BH-A use beryllium copper center contacts. TC-400-NF-X uses standard copper. Both are gold-plated. Beryllium copper provides enhanced spring characteristics and contact durability.

Q: Are all three connectors compatible with LMR-400 cable?

A: Yes. All three connectors are specified for LMR-400 cable group compatibility with threaded fastening.
