R143453000 TNC Coaxial Connector Equivalent & Substitute Parts

Part Overview

The R143453000 is a TNC connector jack with female socket configuration, designed for 50 Ohms RF applications requiring panel mount installation. This component features a two-hole flange mounting design with solder cup termination for both center contact and shield. The part is currently active in production status with 1006 units in stock. Substitute parts are identified to provide alternative flange mounting configurations while maintaining electrical and mechanical compatibility for applications where the two-hole flange design may not be required or where alternative packaging formats are preferred.

Substitute Part Grouping Explanation

Substitute parts R143404000 and R143405000 are classified as parametric equivalents to R143453000 based on the following critical parameters that determine substitution eligibility:

Electrical Parameters (Must Match):

• Connector Style: TNC
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 11 GHz
• Voltage Rating: 500 V
• Insertion Loss: 0.18 dB

Mechanical Parameters (Must Match):

• Contact Termination: Solder Cup
• Shield Termination: Solder
• Mounting Type: Panel Mount
• Fastening Type: Threaded
• Number of Ports: 1

Material & Environmental Parameters (Must Match):

• Center Contact Material: Beryllium Copper
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Plating: Gold
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Operating Temperature: -65°C ~ 165°C
• Features: Extended Insulation
• Housing Color: Silver

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• ECCN: EAR99
• HTSUS: 8536.69.4010

The primary difference between the main part and substitutes is the flange mounting feature configuration (two-hole flange versus square flange) and packaging format (bulk versus box). These differences do not affect electrical performance or core mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—R143453000, R143404000, and R143405000—are active production components manufactured by Radiall USA, Inc., and maintain full ROHS3 compliance. Selection between these parts should be based on the following criteria:

Flange Mounting Configuration: The primary technical distinction is the flange design. R143453000 features a two-hole flange mounting configuration, while R143404000 and R143405000 feature square flange configurations. Panel cutout dimensions and fastening hole patterns will determine which flange style is compatible with the target application.

Packaging Format: R143453000 is supplied in bulk packaging, while R143404000 and R143405000 are supplied in box packaging. Packaging selection depends on procurement requirements and inventory management practices.

Electrical and Mechanical Equivalence: All three parts deliver identical electrical performance across the 50 Ohms impedance specification, 11 GHz maximum frequency, 500 V voltage rating, and 0.18 dB insertion loss. All parts support the same operating temperature range (-65°C ~ 165°C) and mating cycle rating (500 cycles).

Compliance and Regulatory: All parts carry identical compliance certifications (ROHS3, EAR99, HTSUS 8536.69.4010), ensuring regulatory equivalence for applications subject to these standards.

Frequently Asked Questions (FAQ)

Q: Can R143404000 or R143405000 be used as direct replacements for R143453000?

A: R143404000 and R143405000 are electrical and mechanical equivalents to R143453000 with respect to all RF performance parameters, termination methods, and environmental ratings. The primary difference is the flange mounting feature (two-hole versus square). Direct substitution is possible only if the panel cutout and fastening hole pattern accommodate the square flange design of the substitute parts.

Q: What is the difference between R143404000 and R143405000?

A: R143404000 and R143405000 are identical in all electrical, mechanical, and material specifications. Both feature square flange mounting and box packaging. The parts differ only in current inventory levels (849 Pcs for R143404000 and 967 Pcs for R143405000).

Q: Are there any performance differences between the two-hole flange and square flange configurations?

A: No. Both flange configurations deliver identical electrical performance, impedance characteristics, and frequency response. The flange type is a mechanical mounting feature only and does not affect RF performance parameters.

Q: What packaging considerations should be evaluated when selecting between these parts?

A: R143453000 is supplied in bulk packaging, while R143404000 and R143405000 are supplied in box packaging. Bulk packaging is typically used for high-volume applications, while box packaging is standard for component distribution and smaller quantity orders. Packaging selection should align with procurement volume and handling requirements.

Q: Are all three parts RoHS compliant?

A: Yes. R143453000, R143404000, and R143405000 are all ROHS3 compliant. All parts also carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications.

Q: What is the maximum operating frequency for these connectors?

A: All three parts support a maximum frequency of 11 GHz, making them suitable for RF applications across this bandwidth.

Q: Can these connectors be used in high-temperature environments?

A: Yes. All three parts are rated for continuous operation across the temperature range of -65°C to 165°C, supporting both cryogenic and elevated temperature applications.
