Amphenol RF 000-8575 BNC Connector Equivalent & Substitute Parts

Part Overview

The Amphenol RF 000-8575 is an active BNC connector plug designed for RF coaxial applications requiring 50-ohm impedance. This right-angle, free-hanging solder-terminated connector operates at frequencies up to 4 GHz and is compatible with standard RG-59, 59B, 62, 140, 210, and Belden cable series. The part is currently in active production status with 784 units in stock. Substitute parts become necessary when solder termination is incompatible with application requirements, when specific dielectric materials are mandated, or when alternative contact plating specifications are required for system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 000-8575 is determined by the following critical parameters that must remain constant across equivalent parts:

Fixed Parameters (Non-Negotiable):

• Connector Style: BNC
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Free Hanging (In-Line), Right Angle
• Fastening Type: Bayonet Lock
• Frequency - Max: 4 GHz
• Voltage Rating: 500 V
• Insertion Loss: 0.2 dB
• Mating Cycles: 500
• Number of Ports: 1

Variable Parameters (Substitution Basis):

• Contact Termination: Solder (main part) vs. Crimp (substitute)
• Shield Termination: Clamp (main part) vs. Crimp (substitute)
• Dielectric Material: Polystyrene PS (main part) vs. Polytetrafluoroethylene PTFE (substitute)
• Center Contact Plating: Silver (main part) vs. Gold (substitute)
• Cable Group Compatibility: Subset compatibility acceptable

The TE Connectivity AMP Connectors 5225974-5 qualifies as a substitute because it maintains all fixed parameters while offering alternative termination and material specifications suitable for different assembly and environmental requirements.

Engineering Selection Recommendations

Primary Selection: Amphenol RF 000-8575

The Amphenol RF 000-8575 is the recommended primary choice for new designs and applications. This part maintains active product status, ensuring long-term availability and supply chain stability. It carries ROHS3 compliance certification and is fully REACH affected compliant. The solder termination method provides direct integration with PCB assembly processes and cable soldering workflows. Silver center contact plating offers standard RF performance characteristics across the 4 GHz operating range.

Substitute Selection: TE Connectivity AMP Connectors 5225974-5

The TE Connectivity 5225974-5 serves as a functional equivalent for applications where crimp termination is the assembly method. This part is classified as obsolete, indicating limited future availability. The crimp termination and crimp shield termination require specialized crimping tools and fixtures. The PTFE dielectric material provides superior frequency stability and lower dielectric loss compared to polystyrene, making it suitable for high-frequency or temperature-sensitive applications. Gold center contact plating enhances corrosion resistance in harsh environmental conditions. RoHS compliance (non-ROHS3) indicates this part may not meet the most current regulatory requirements for new product certifications.

Compliance Considerations:

Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, confirming equivalent export control and tariff treatment. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings, eliminating moisture-related handling constraints. The primary regulatory difference is ROHS3 compliance on the main part versus standard RoHS compliance on the substitute, which may impact suitability for specific regional or customer requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5225974-5 be used as a direct replacement for the Amphenol RF 000-8575?

A: The TE Connectivity 5225974-5 is functionally equivalent in RF performance and mechanical fit. However, it differs in termination method (crimp vs. solder) and dielectric material (PTFE vs. polystyrene). Direct substitution requires compatibility with crimp assembly processes and acceptance of PTFE dielectric characteristics. The obsolete product status of the TE part may limit future availability.

Q: What is the impact of different dielectric materials on connector performance?

A: The Amphenol RF 000-8575 uses polystyrene (PS) dielectric, while the TE Connectivity 5225974-5 uses polytetrafluoroethylene (PTFE). Both materials support the specified 4 GHz maximum frequency and 0.2 dB insertion loss. PTFE offers superior temperature stability and lower dielectric loss at higher frequencies, while polystyrene provides standard RF performance at lower cost.

Q: Are the cable compatibility groups interchangeable between these parts?

A: The Amphenol RF 000-8575 supports RG-59, 59B, 62, 140, 210, Belden 8241, 8263, 8279, 9209. The TE Connectivity 5225974-5 supports RG-59, 59A, 59B, 62, 62A, 62B. Both parts are compatible with RG-59, 59B, and 62 cable groups. The Amphenol part supports additional cable types (140, 210, and specific Belden series), while the TE part supports 59A, 62A, and 62B variants. Cable selection must be verified against the specific connector being used.

Q: What are the assembly implications of solder versus crimp termination?

A: Solder termination (Amphenol RF 000-8575) requires soldering equipment and skilled operators for reliable connections. Crimp termination (TE Connectivity 5225974-5) requires specialized crimping tools and dies specific to the connector geometry. Solder termination is reversible; crimp termination is permanent. Both methods achieve equivalent electrical performance when executed correctly.

Q: Does the gold plating on the TE Connectivity part provide performance advantages?

A: Gold center contact plating on the TE Connectivity 5225974-5 provides enhanced corrosion resistance compared to silver plating on the Amphenol RF 000-8575. Both platings deliver equivalent RF performance across the 4 GHz operating range. Gold plating is beneficial in high-humidity, salt-spray, or chemically aggressive environments where silver oxidation may occur.

Q: What is the significance of the obsolete product status for the TE Connectivity part?

A: Obsolete status indicates the TE Connectivity 5225974-5 is no longer in active production. While 910 units are currently in stock, future availability cannot be guaranteed. New designs should prioritize the active Amphenol RF 000-8575 to ensure long-term supply chain continuity and support.

Q: Are both parts suitable for the same frequency range and impedance applications?

A: Yes. Both parts operate at 50 ohms impedance with a maximum frequency of 4 GHz and identical 0.2 dB insertion loss specifications. Both support 500 mating cycles and 500 V voltage rating. They are electrically equivalent for RF applications within these parameters.
