Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

Part 221185-8 and 5221185-8 are parametric equivalents to the 413589-8. Both maintain the same electrical performance, impedance, frequency rating, and cable compatibility. However, both parts carry obsolete product status. Part 5221185-8 offers the advantage of RoHS compliance and REACH affected status, making it suitable for applications with environmental regulatory requirements. Part 221185-8 maintains the same RoHS non-compliant status as the main part.

For Enhanced Performance and Compliance:

Part 31-71013 (Amphenol RF) is an active product that provides full electrical and mechanical compatibility with the 413589-8 while offering ROHS3 compliance. This part features an extended operating temperature range (-65°C to 165°C) compared to the main part (-55°C to 85°C), making it suitable for extreme temperature applications. The body material is brass rather than zinc, and the dielectric uses PTFE instead of polyethylene. Insertion loss increases slightly to 0.2 dB. This part is recommended for new designs requiring RoHS3 compliance and extended temperature performance.

For Solder Termination Applications:

Part 031-71013-RFX (Amphenol RF) is an active product offering solder termination instead of crimp. This part extends the frequency capability to 3 GHz and provides ROHS3 compliance. The operating temperature range is narrower (-40°C to 80°C) than the main part. This part is suitable for applications where solder termination is preferred over crimp and where higher frequency performance is required. The dielectric material is polyoxymethylene acetal rather than polyethylene.

Compliance Considerations:

The main part 413589-8 is RoHS non-compliant. For applications requiring RoHS compliance, parts 5221185-8, 31-71013, and 031-71013-RFX all provide compliant alternatives. For ROHS3 compliance specifically, parts 31-71013 and 031-71013-RFX are the appropriate selections.

Frequently Asked Questions (FAQ)

Q: Can I use part 221185-8 or 5221185-8 as a direct replacement for 413589-8?

A: Yes, both parts are parametric equivalents with identical electrical specifications, impedance, frequency rating, and cable compatibility. However, both are obsolete products. Part 5221185-8 is preferred if RoHS compliance is required. Availability should be confirmed before selection.

Q: What is the difference between the crimp-terminated 31-71013 and the solder-terminated 031-71013-RFX?

A: The primary difference is the contact termination method. Part 31-71013 uses crimp termination matching the main part, while 031-71013-RFX uses solder termination. Additionally, 031-71013-RFX extends the frequency capability to 3 GHz but has a narrower operating temperature range (-40°C to 80°C versus -65°C to 165°C for 31-71013).

Q: Which substitute part should I select for a new design?

A: For new designs, select from the active products: 31-71013 or 031-71013-RFX. Part 31-71013 is recommended if crimp termination and extended temperature performance are required. Part 031-71013-RFX is recommended if solder termination and higher frequency capability (3 GHz) are required. Both provide ROHS3 compliance.

Q: Are all substitute parts compatible with the same cable types?

A: Parts 413589-8, 221185-8, and 5221185-8 are compatible with RG-179, 179A, 179B, 187, and 187A cables. Parts 31-71013 and 031-71013-RFX extend compatibility to include Belden 9221 and M17/94-RG179 cables, providing broader cable support.

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

A: The main part uses zinc body material, while substitute parts 31-71013 and 031-71013-RFX use brass. Brass provides superior thermal conductivity and mechanical durability, supporting the extended operating temperature range in 31-71013. The dielectric material also differs: polyethylene in the main part versus PTFE in 31-71013 and polyoxymethylene acetal in 031-71013-RFX. These material differences contribute to the performance characteristics of each part.

Q: What does the insertion loss difference mean for my application?

A: The main part 413589-8 has insertion loss of 0.15 dB, while substitute parts 31-71013 and 031-71013-RFX have 0.2 dB insertion loss. This 0.05 dB difference is minimal for most applications but may be significant in high-frequency, low-noise systems where signal integrity is critical.

Q: Can I use these connectors interchangeably in existing assemblies?

A: All substitute parts maintain the same BNC connector style, bayonet lock fastening, and free-hanging mounting configuration. Physical and electrical interchangeability is confirmed for all listed substitutes. However, termination method differences (crimp versus solder) require appropriate assembly equipment and procedures.

Q: What is the significance of the different operating temperature ranges?

A: The main part operates from -55°C to 85°C. Part 31-71013 extends this to -65°C to 165°C, suitable for extreme temperature environments. Part 031-71013-RFX operates from -40°C to 80°C, which is narrower than the main part. Application temperature requirements should determine which part is appropriate.

Q: Are there any RoHS compliance differences I should consider?

A: The main part 413589-8 is RoHS non-compliant. Parts 5221185-8, 31-71013, and 031-71013-RFX are all RoHS compliant. Parts 31-71013 and 031-71013-RFX specifically meet ROHS3 requirements. For applications subject to RoHS regulations, these compliant alternatives are necessary.
