Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 000-77175 are qualified based on the following criteria:

Core Compatibility Parameters:

• Connector Style: TNC
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded
• Voltage Rating: 500 V
• Mating Cycles: 500
• Body Material: Brass
• Body Finish: Nickel
• Dielectric Material: PTFE
• Moisture Sensitivity Level: 1 (Unlimited)

Substitution Variance: The identified substitute parts differ in contact termination method (crimp versus solder), cable group compatibility, and regulatory compliance status. These differences establish distinct application contexts where each part is appropriate.

Engineering Selection Recommendations

Primary Selection (000-77175 - Amphenol RF): Select this part for applications requiring solder termination with silver-plated center contacts. This connector is ROHS3 compliant and maintains active product status. Use with cable groups RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907.

Alternative Selection (5225555-5 - TE Connectivity): This part is suitable for crimp termination applications with RG-141 and RG-141A cables. It maintains active product status and ROHS3 compliance, matching the regulatory profile of the primary part. Operating temperature range is specified as -65°C to 165°C.

Secondary Alternative (225555-6 - TE Connectivity): This part is suitable for crimp termination with RG-142, RG-142A, and RG-142B cables. Note that this part is RoHS non-compliant, which may restrict use in regulated applications. It is active and includes connector, contact, and ferrule components.

Obsolete Alternative (5225555-2 - TE Connectivity): This part is obsolete and should not be selected for new designs. It is retained in this reference for legacy system maintenance only. It is RoHS compliant and compatible with RG-58A and RG-58C cables.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Amphenol RF 000-77175 with a TE Connectivity crimp connector?

A: Substitution is possible if the application permits crimp termination instead of solder termination. The core electrical and mechanical parameters (TNC style, 50-ohm impedance, threaded fastening, 500V rating, 500 mating cycles) are identical. However, cable group compatibility must be verified. The 5225555-5 is recommended for RG-141/141A cables, while 225555-6 is for RG-142/142A/142B cables.

Q: What is the difference between the three TE Connectivity substitute parts?

A: All three TE Connectivity parts use crimp termination but differ in cable compatibility, product status, and compliance. The 5225555-5 is active and ROHS3 compliant for RG-141/141A cables. The 225555-6 is active but RoHS non-compliant for RG-142/142A/142B cables. The 5225555-2 is obsolete and should not be used for new designs.

Q: Does the center contact plating material affect substitution?

A: The primary part uses silver plating while all substitute parts use gold plating. Both materials are acceptable for 50-ohm RF applications at the specified voltage and frequency ranges. Selection should be based on cable compatibility and termination method requirements rather than plating material.

Q: Are all substitute parts RoHS compliant?

A: No. The 5225555-5 is ROHS3 compliant and the 5225555-2 is RoHS compliant. The 225555-6 is RoHS non-compliant. For applications requiring RoHS compliance, use either the primary part (000-77175) or the 5225555-5 substitute.

Q: What cable groups are compatible with each part?

A: The primary part (000-77175) supports RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. The 5225555-5 supports RG-141 and 141A. The 225555-6 supports RG-142, 142A, and 142B. The 5225555-2 supports RG-58A and 58C. Cable group selection determines which connector is appropriate for your application.

Q: Can I use these connectors in high-frequency applications?

A: The substitute parts specify a maximum frequency of 11 GHz. The primary part does not specify a maximum frequency. For applications requiring frequency specifications, the substitute parts provide documented performance up to 11 GHz.
