UPL220-020 BNC Connector Plug 75 Ohm Crimp - Equivalent & Substitute Parts

Part Overview

The UPL220-020 is a BNC connector plug manufactured by Cinch Connectivity Solutions Trompeter, designed for 75 ohm coaxial cable applications. This male pin connector features crimp termination for the Belden 9248 cable group and operates across a frequency range up to 4 GHz with a temperature range of -65°C to 165°C. The part is currently active in production status with RoHS compliance certification.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design requirements allow for compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

• Connector Style: BNC
• Connector Type: Plug, Male Pin
• Impedance: 75 Ohms
• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Voltage Rating: 500 V
• Center Contact Plating: Gold
• Body Finish: Nickel

Substitute parts are grouped into two categories:

Direct Substitutes maintain all core electrical and mechanical parameters with identical or superior performance characteristics. These parts are fully interchangeable without design modification.

Similar Substitutes maintain core connector parameters but may differ in cable group compatibility, frequency range, operating temperature range, dielectric material, or body material composition. Selection requires verification that the specific cable group and frequency/temperature requirements align with the application.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes for New Designs:

031-70013 (Amphenol RF) is the primary recommended substitute. This part maintains active product status, matches all core electrical parameters including 4 GHz frequency capability and -65°C to 165°C operating range, and carries ROHS3 compliance. The part is compatible with RG-179 series cables and Belden 9221, providing broader cable group support than the original part.

31-71013 (Amphenol RF) is an alternative active-status substitute with identical core specifications. This part supports RG-179 series cables and maintains full temperature and frequency performance. Selection between 031-70013 and 31-71013 depends on cable group requirements for the specific application.

Substitutes for Existing Designs (Not For New Designs Status):

031-70238 (Amphenol RF) provides full electrical and thermal compatibility with identical 4 GHz frequency and -65°C to 165°C operating range. This part is marked "Not For New Designs" and should be used only for legacy system maintenance or replacement scenarios.

031-80109 (Amphenol RF) and 031-80101 (Amphenol RF) maintain 4 GHz frequency capability and full temperature range but feature phosphor bronze body material instead of brass. These parts are marked "Not For New Designs" and carry REACH Affected status, requiring compliance verification for regulated applications.

Limited Compatibility Substitutes:

031-71008-1RFX, 31-71008, 31-71008-1000, and 31-71008-RFX operate at reduced 2 GHz maximum frequency. These parts are suitable only for applications where the 2 GHz frequency ceiling meets design requirements. All are marked "Not For New Designs."

031-70237 (Amphenol RF) operates at 3 GHz maximum frequency with restricted temperature range (-40°C to 85°C). This part is suitable only for applications within these narrower operating parameters and is marked "Not For New Designs."

Frequently Asked Questions (FAQ)

Q: Can I use 031-70013 as a direct replacement for UPL220-020?

A: Yes. Both parts maintain 75 ohm impedance, 4 GHz frequency capability, -65°C to 165°C operating temperature, crimp termination, and bayonet lock fastening. 031-70013 is active status and ROHS3 compliant. The primary difference is cable group compatibility: 031-70013 supports RG-179 series and Belden 9221, while UPL220-020 is specified for Belden 9248. Verify that your cable group is compatible with the substitute before implementation.

Q: Why are some substitutes marked "Not For New Designs"?

A: Parts marked "Not For New Designs" indicate that the manufacturer has discontinued active development and production for new applications. These parts may remain available for existing system support or legacy applications but should not be selected for new product designs. For new designs, select from parts with "Active" product status.

Q: What is the difference between 031-70013 and 31-71013?

A: Both parts are active status and maintain identical core electrical specifications. The primary difference is the cable group compatibility: 031-70013 supports RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179, while 31-71013 supports the same cable groups. Selection depends on which cable group your application requires.

Q: Can I use parts with 2 GHz frequency rating in place of the 4 GHz UPL220-020?

A: No. Parts such as 31-71008, 31-71008-1000, 031-71008-1RFX, and 31-71008-RFX are rated for 2 GHz maximum frequency. These substitutes are suitable only for applications operating below 2 GHz. If your application requires 4 GHz capability, select from parts rated for 4 GHz: 031-70013, 031-70238, 031-80109, or 031-80101.

Q: What does ROHS3 compliance mean compared to RoHS Compliant?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard. The original UPL220-020 carries "RoHS Compliant" designation, while substitute parts carry "ROHS3 Compliant." Both are acceptable for regulated applications; ROHS3 represents the current standard version.

Q: Are there cable group restrictions I should know about?

A: Yes. The original UPL220-020 is specified for Belden 9248 cable. Substitute parts support different cable groups: 031-70013 and 31-71013 support RG-179 series and Belden 9221; 031-70237 and 031-70238 support AT&T 735 series and Belden 735A1; 031-71008-1RFX, 31-71008, 31-71008-1000, and 31-71008-RFX support RG-59 series and Belden 8241, 8263, 8279, 9209. Verify that the substitute part's cable group is compatible with your application before selection.

Q: What is the significance of body material differences (Brass vs. Phosphor Bronze)?

A: Both brass and phosphor bronze body materials meet the core electrical specifications for 75 ohm impedance and crimp termination. Phosphor bronze (used in 031-80109 and 031-80101) provides enhanced mechanical durability and mating cycle performance. Selection between these materials depends on application-specific requirements for mechanical robustness and mating cycle frequency.
