Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPLR220-025 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Connector style must be BNC
• Connector type must be Plug, Male Pin
• Impedance must be 75 Ohms
• Fastening type must be Bayonet Lock
• Contact and shield termination must both be Crimp

Mechanical Compatibility Requirements:

• Mounting type must be Free Hanging (In-Line), Right Angle
• Dielectric material must be Polytetrafluoroethylene (PTFE)
• Body finish must be Nickel
• Center contact plating must be Gold

Performance Envelope:

• Frequency maximum must meet or exceed 4 GHz
• Voltage rating must be 500 V or higher
• Operating temperature range must encompass the application requirements

The substitute part 031-80904 from Amphenol RF satisfies all electrical and mechanical compatibility criteria. However, differences exist in body material composition, operating temperature range, and frequency specification that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 031-80904 from Amphenol RF is an active product suitable for substitution in applications where the following conditions are met:

Frequency Consideration: The substitute part specifies a maximum frequency of 3 GHz, compared to the original part's 4 GHz specification. Applications operating at frequencies between 3 GHz and 4 GHz require evaluation of actual system performance requirements.

Temperature Consideration: The substitute part operates within -40°C to 85°C, whereas the original part operates within -65°C to 165°C. Applications requiring operation outside the -40°C to 85°C range are not suitable for this substitute without additional thermal analysis.

Material Composition: The substitute part uses zinc alloy body material instead of brass. Both materials are nickel-finished and provide equivalent shielding and mechanical properties for standard RF applications.

Compliance Status: Both parts are RoHS compliant. The substitute part carries ROHS3 compliance and REACH affected status, meeting current environmental regulations.

Product Status: The substitute part is active and in production, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the 031-80904 be used as a direct replacement for UPLR220-025 in all applications?

A: The 031-80904 is electrically and mechanically compatible for applications operating at frequencies up to 3 GHz and temperatures between -40°C and 85°C. Applications requiring the full 4 GHz frequency range or extended temperature operation require specific evaluation.

Q: What is the significance of the body material difference between brass and zinc alloy?

A: Both brass and zinc alloy bodies, when nickel-finished, provide adequate RF shielding and mechanical durability for standard coaxial connector applications. The material difference does not affect electrical performance in typical 75-ohm video and RF signal transmission.

Q: Are the crimp termination specifications identical between the two parts?

A: Both parts use crimp termination for both contact and shield. The crimp specifications are determined by the cable group compatibility. The original part supports Lucent 734A cable, while the substitute supports AT&T 734, 734A, and Belden 1505A cables, providing broader compatibility.

Q: What does the mating cycles specification of 500 for the substitute part indicate?

A: The mating cycles specification indicates the connector can withstand 500 connect-disconnect cycles while maintaining electrical and mechanical integrity. This specification is not provided for the original part.

Q: Is the 0.2 dB insertion loss specification critical for substitution decisions?

A: Insertion loss of 0.2 dB is typical for BNC connectors in this class and is acceptable for most video and RF applications. This specification is provided for the substitute part but not for the original part, indicating both perform within standard industry parameters.

Q: How does the RoHS compliance difference affect substitution?

A: Both parts are RoHS compliant. The substitute part carries ROHS3 compliance, which is the current regulatory standard. This represents an improvement in environmental compliance and regulatory alignment.

Q: What cable groups are compatible with each connector?

A: The original UPLR220-025 supports Lucent 734A cable. The substitute 031-80904 supports AT&T 734, 734A, and Belden 1505A cables. The substitute provides broader cable compatibility while maintaining 75-ohm impedance matching.
