Engineering Selection Recommendations

Tier 1 - Direct Substitutes (Active Product Status, Full Compliance):

Amphenol RF 31-71013 is the primary substitute for the 031-80101. Both parts are manufactured by Amphenol RF and share identical core specifications including 75-ohm impedance, crimp termination, PTFE dielectric, and ROHS3 compliance. The 31-71013 carries active product status, making it the preferred choice for new designs. The maximum frequency specification of 2 GHz is lower than the main part's 4 GHz rating; however, this remains suitable for applications operating below 2 GHz. The 31-71013 includes an additional sleeve component in its package (4 pcs vs. 3 pcs).

Cinch Connectivity Solutions Trompeter UPL220-004 provides an alternative from a different manufacturer while maintaining full electrical and mechanical compatibility. This part operates at 4 GHz maximum frequency, matching the main part's performance envelope. Operating temperature range extends to -65°C to 165°C, identical to the 031-80101. The UPL220-004 carries active product status and ROHS3 compliance. Cable group compatibility includes RG-179 and RG-187, with an additional bushing component included in the package.

Cinch Connectivity Solutions Trompeter UPL2000-D7 operates at 4 GHz maximum frequency and maintains 75-ohm impedance with crimp termination. This part carries active product status and ROHS3 compliance. The operating temperature range of -40°C to 85°C is narrower than the main part; this part is suitable for applications within this thermal envelope. Housing color is black rather than silver.

Tier 2 - Functional Substitutes (Active Status, Compliance Considerations):

TE Connectivity AMP Connectors 5413589-6 provides functional equivalence with RoHS compliance (RoHS Compliant status). This part operates at 2 GHz maximum frequency and -55°C to 85°C operating temperature range. The insertion loss specification of 0.15 dB is superior to the main part's 0.2 dB. This part is suitable for applications operating below 2 GHz within the specified thermal range.

TE Connectivity AMP Connectors 413589-6 carries active product status but is RoHS non-compliant, making it unsuitable for applications requiring RoHS certification. This part operates at 2 GHz maximum frequency and features polyethylene (PE) dielectric material rather than PTFE. The insertion loss of 0.15 dB is superior to the main part. This part is restricted to legacy applications or systems without RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can I use the Amphenol RF 31-71013 as a direct replacement for the 031-80101?

A: Yes. Both parts are manufactured by Amphenol RF and share identical core specifications: 75-ohm impedance, BNC plug male pin configuration, crimp termination for both center contact and shield, free-hanging mounting, and bayonet lock fastening. Both operate at 500 V with -65°C to 165°C temperature range and ROHS3 compliance. The 31-71013 carries active product status, making it the recommended choice for new applications. The 2 GHz frequency limit of the 31-71013 is lower than the 031-80101's 4 GHz specification; verify your application's frequency requirements before selection.

Q: What is the difference between the Cinch UPL220-004 and UPL2000-D7?

A: Both parts are BNC plug connectors with 75-ohm impedance and crimp termination from Cinch Connectivity Solutions Trompeter. The UPL220-004 operates at 4 GHz maximum frequency with -65°C to 165°C operating temperature range and includes a bushing component. The UPL2000-D7 also operates at 4 GHz but has a narrower operating temperature range of -40°C to 85°C and features black housing instead of silver. Select based on your thermal requirements and housing color specifications.

Q: Are the TE Connectivity parts (413589-6 and 5413589-6) suitable replacements?

A: Both TE Connectivity parts maintain 75-ohm impedance and BNC plug male pin configuration with crimp termination. The 5413589-6 carries RoHS compliance and is suitable for applications requiring RoHS certification. The 413589-6 is RoHS non-compliant and restricted to legacy systems. Both parts operate at 2 GHz maximum frequency, which is lower than the 031-80101's 4 GHz specification. These parts are suitable only for applications operating below 2 GHz within the -55°C to 85°C temperature range.

Q: What cable types are compatible with these substitute parts?

A: The 031-80101 is compatible with RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179 cables. The 31-71013 shares identical cable group compatibility. The UPL220-004 supports RG-179 and RG-187. The UPL2000-D7 supports RG-179 and Belden 9221. The TE Connectivity parts (413589-6 and 5413589-6) are specified for RG-59 (Double Braid). Verify cable compatibility before final selection.

Q: Why is the 031-80101 marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's product line. The Amphenol RF 31-71013 is the active replacement offering equivalent functionality with current product support. For new designs, select from parts with "Active" product status: 31-71013, UPL220-004, UPL2000-D7, 5413589-6, or 413589-6.

Q: What are the package inclusions for each part?

A: The 031-80101 includes 3 pieces (1 connector, 1 contact, 1 ferrule). The 31-71013 includes 4 pieces (1 connector, 1 contact, 1 ferrule, 1 sleeve). The UPL220-004 includes 4 pieces (1 connector, 1 bushing, 1 contact, 1 sleeve). The UPL2000-D7 package inclusions are not specified. The TE Connectivity parts (413589-6 and 5413589-6) include 3 pieces (1 connector, 1 contact, 1 ferrule). Verify package contents match your assembly requirements.

Q: Which substitute offers the best insertion loss performance?

A: The TE Connectivity parts (413589-6 and 5413589-6) specify 0.15 dB insertion loss, which is superior to the 031-80101's 0.2 dB specification. The 31-71013 matches the main part at 0.2 dB. The UPL220-004 and UPL2000-D7 do not specify insertion loss values. For applications requiring minimum insertion loss, the TE Connectivity parts provide measurable improvement.

Q: Are all substitute parts ROHS3 compliant?

A: The 031-80101, 31-71013, UPL220-004, and UPL2000-D7 are all ROHS3 compliant. The 5413589-6 is RoHS compliant. The 413589-6 is RoHS non-compliant. For applications requiring RoHS certification, exclude the 413589-6 from consideration.
