Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 031-369 is determined by the following critical parameters:

Core Electrical Parameters:

• Connector style (BNC)
• Connector type (Jack, Female Socket)
• Impedance (50 Ohms)
• Maximum frequency (4 GHz)
• Voltage rating (500 V)
• Mating cycles (500)

Material and Contact Specifications:

• Center contact material (Beryllium Copper)
• Center contact plating (Gold)
• Body finish (Nickel)
• Fastening type (Bayonet Lock)

Compliance and Environmental:

• RoHS3 compliance
• Moisture sensitivity level (1 - Unlimited)
• Operating temperature range compatibility

The TE Connectivity AMP Connectors part 5413771-3 qualifies as a substitute based on matching impedance, frequency rating, voltage rating, mating cycles, center contact material, center contact plating, body finish, fastening type, and compliance certifications. Differences in contact termination method (crimp versus solder), mounting type (panel mount versus through-hole), dielectric material, and operating temperature range represent functional variations that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Amphenol RF 031-369 Selection Criteria: The 031-369 is appropriate for applications requiring solder termination of the center contact, through-hole PCB mounting, and extended operating temperature range (-65°C to 165°C). This part maintains ROHS3 compliance and REACH compliance status. The PTFE dielectric material provides superior high-frequency performance characteristics. Insertion loss is specified at 0.2 dB.

TE Connectivity 5413771-3 Selection Criteria: The 5413771-3 is appropriate for panel-mount applications utilizing bulkhead front-side nut mounting with crimp termination for both center contact and shield. This part maintains ROHS3 compliance and REACH compliance status. The operating temperature range is limited to -55°C to 85°C, restricting use in extreme cold or high-temperature environments. The PMP dielectric material differs from the primary part specification.

Substitution Applicability: Direct substitution is limited by differences in contact termination method, mounting configuration, dielectric material, and operating temperature range. Selection between these parts must be based on specific application requirements for termination method, mounting type, and thermal environment. Both parts satisfy identical electrical specifications for impedance, frequency, voltage rating, and mating cycles.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5413771-3 directly replace the Amphenol RF 031-369 in all applications?

A: No. While both connectors share identical impedance (50 Ohms), frequency rating (4 GHz), voltage rating (500 V), and mating cycle specifications (500), they differ in contact termination method (solder versus crimp), mounting type (through-hole versus panel mount), dielectric material (PTFE versus PMP), and operating temperature range (-65°C to 165°C versus -55°C to 85°C). Direct substitution is only valid when the application requirements align with the TE Connectivity part's specifications.

Q: What is the primary functional difference between these two BNC connectors?

A: The primary difference is the contact termination method. The Amphenol RF 031-369 uses solder termination for the center contact, suitable for PCB through-hole mounting. The TE Connectivity 5413771-3 uses crimp termination for both center contact and shield, designed for panel-mount bulkhead applications. This difference affects assembly method, mechanical mounting configuration, and cable attachment approach.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Amphenol RF 031-369 and TE Connectivity 5413771-3 are ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the significance of the dielectric material difference?

A: The Amphenol RF 031-369 uses PTFE (Polytetrafluoroethylene) dielectric material, while the TE Connectivity 5413771-3 uses PMP (Polymethylpentene) dielectric material. PTFE provides superior electrical properties at high frequencies and broader temperature stability. PMP offers different mechanical and thermal characteristics. Selection depends on specific application frequency response and environmental requirements.

Q: Which part is suitable for high-temperature applications?

A: The Amphenol RF 031-369 operates across -65°C to 165°C, making it suitable for high-temperature environments. The TE Connectivity 5413771-3 operates across -55°C to 85°C, limiting its use in applications exceeding 85°C. For thermal environments above 85°C, the Amphenol RF part is the appropriate selection.

Q: What does the insertion loss specification indicate?

A: The Amphenol RF 031-369 specifies insertion loss at 0.2 dB, indicating the signal attenuation introduced by the connector at operating frequencies. The TE Connectivity 5413771-3 does not provide an insertion loss specification in the available data. For applications where insertion loss is a critical parameter, the Amphenol RF part provides documented performance.

Q: Are both connectors suitable for 50-ohm RF applications?

A: Yes. Both connectors are specified for 50-ohm impedance and support frequencies up to 4 GHz, making them suitable for standard RF and microwave applications operating within these electrical parameters.

Q: What is the significance of the 500 mating cycle rating?

A: The 500 mating cycle rating indicates the connector is designed to withstand 500 connect-disconnect cycles while maintaining electrical and mechanical performance. Both parts share this specification, indicating equivalent mechanical durability for applications with moderate connector cycling requirements.
