Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 082-4426 are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters for Substitution:

• Connector Style: N Type (mandatory match)
• Connector Type: Plug, Male Pin (mandatory match)
• Impedance: 50 Ohms (mandatory match)
• Mounting Type: Free Hanging (In-Line) (mandatory match)
• Frequency - Max: 11 GHz (mandatory match)
• Operating Temperature Range: -65°C to 165°C (mandatory match)
• Fastening Type: Threaded (mandatory match)
• Contact Termination: Crimp or Solder capability (mandatory match)
• Shield Termination: Crimp (mandatory match)

Acceptable Variation Parameters:

• Product Status: Active alternatives acceptable for obsolete part
• Packaging: Bulk packaging acceptable
• RoHS Compliance: ROHS3 acceptable for ROHS Compliant requirement
• Voltage Rating: Equal or higher rating acceptable
• Cable Group: Subset compatibility acceptable if primary cable groups supported

The 082-4425 (Amphenol RF) qualifies as a direct equivalent with identical specifications and active product status. The 51692-2 (TE Connectivity) qualifies as a compatible substitute with matching core electrical parameters, though with reduced cable group compatibility and lower voltage rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Amphenol RF 082-4425

The 082-4425 is the preferred substitute for the obsolete 082-4426. Both parts are manufactured by Amphenol RF and share identical electrical and mechanical specifications. The 082-4425 maintains active product status with ROHS3 compliance and REACH affected status, ensuring long-term availability and regulatory alignment. Cable group compatibility is identical across all supported coaxial cable types. Voltage rating and insertion loss specifications are equivalent. The 082-4425 is suitable for direct replacement in all applications where the 082-4426 was originally specified.

Secondary Recommendation: TE Connectivity 51692-2

The 51692-2 qualifies as a compatible substitute when cable group flexibility is not required. This part maintains the core electrical parameters: N Type connector style, 50 Ohm impedance, 11 GHz frequency rating, and -65°C to 165°C operating temperature range. The 51692-2 is limited to RG-213 cable group compatibility, making it suitable only for applications specifically using RG-213 coaxial cable. The voltage rating of 1000 V is lower than the original 1500 V specification; applications requiring the full 1500 V rating must use the 082-4425. The 51692-2 carries ROHS3 compliance and REACH affected status. Contact termination is crimp only, eliminating solder termination options available with the 082-4426 and 082-4425.

Frequently Asked Questions (FAQ)

Q: Can the 082-4425 be used as a direct replacement for the 082-4426?

A: Yes. The 082-4425 is a direct equivalent with identical electrical and mechanical specifications. Both parts feature N Type connector style, 50 Ohm impedance, 11 GHz frequency rating, crimp or solder termination, and support the same cable group range. The primary difference is product status: 082-4426 is obsolete while 082-4425 is active.

Q: What are the limitations of using the TE Connectivity 51692-2 as a substitute?

A: The 51692-2 has two key limitations. First, cable group compatibility is restricted to RG-213 only, whereas the original part supports RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, and 393. Second, voltage rating is 1000 V compared to 1500 V for the original part. Contact termination is crimp only, eliminating solder termination capability. Use the 51692-2 only when your application uses RG-213 cable and does not require the full 1500 V voltage rating or solder termination option.

Q: Are all three parts RoHS compliant?

A: Yes. The 082-4426 is RoHS Compliant. Both substitute parts, 082-4425 and 51692-2, are ROHS3 Compliant, which represents a more recent compliance standard. ROHS3 compliance satisfies RoHS requirements.

Q: What is the difference in packaging between these parts?

A: The 082-4426 packaging is not specified in the documentation. The 082-4425 and 51692-2 are both supplied in Bulk packaging. Bulk packaging is standard for coaxial connectors and does not affect electrical or mechanical performance.

Q: Do all three parts support the same operating temperature range?

A: Yes. All three parts operate across the identical temperature range of -65°C to 165°C, ensuring thermal compatibility across applications.

Q: Which part should I select for new designs?

A: For new designs, select the Amphenol RF 082-4425. This part is active, maintains full compatibility with the original 082-4426 specifications, and ensures long-term supply availability. The 082-4425 supports all cable groups and termination methods of the original part.

Q: Can I use the 51692-2 if my application requires solder termination?

A: No. The 51692-2 supports crimp termination only. If your application requires solder termination capability, use the 082-4425, which supports both crimp and solder termination methods.
