Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UG-290/U(40) is determined by strict alignment with the following core parameters:

• Connector Style: BNC
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder Cup
• Shield Termination: Solder
• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Fastening Type: Bayonet Lock
• Frequency - Max: 4 GHz
• Number of Ports: 1
• Dielectric Material: Polytetrafluoroethylene (PTFE)

Both identified substitute parts (Amphenol RF 112511 and RF Industries RFB-1115-14) meet all mandatory substitution criteria. Variations in center contact material, body finish, and plating specifications do not affect functional interchangeability within the defined electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The UG-290/U(40) is designated Last Time Buy status. Both substitute parts are in Active product status, ensuring long-term availability and continued manufacturer support.

Amphenol RF 112511 carries ROHS3 Compliant certification and REACH Affected status, providing enhanced regulatory compliance documentation. This part is suitable for applications requiring extended regulatory traceability.

RF Industries RFB-1115-14 also maintains ROHS3 Compliant status and offers equivalent regulatory standing. This part provides an alternative sourcing option with comparable compliance credentials.

Both substitutes are electrically and mechanically interchangeable with the UG-290/U(40) within the specified parameter set. Selection between alternatives should be based on procurement availability, lead time requirements, and organizational supplier qualification status.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112511 or RF Industries RFB-1115-14 be used as direct replacements for the UG-290/U(40)?

A: Yes. Both parts meet all mandatory substitution criteria: BNC connector style, female socket configuration, 50-ohm impedance, solder cup termination, panel mount with flange, bayonet lock fastening, 4 GHz maximum frequency, and PTFE dielectric material.

Q: What are the differences between the three parts?

A: The primary differences are in center contact material (Beryllium Copper vs. Phosphor Bronze vs. Brass), body finish (Silver vs. Nickel vs. Silver), and center contact plating (Silver vs. Gold vs. Gold). These material variations do not affect electrical performance within the specified 50-ohm, 4 GHz operating envelope.

Q: Are there packaging differences?

A: Yes. The UG-290/U(40) is supplied in Bulk packaging, while both substitute parts are supplied in Bag packaging. This affects handling and inventory management but does not impact component functionality.

Q: What is the significance of the Last Time Buy status for the UG-290/U(40)?

A: Last Time Buy status indicates that the manufacturer will discontinue production. Identifying and qualifying substitute parts ensures design continuity and supply chain resilience for ongoing production requirements.

Q: Do all three parts have the same mating cycle rating?

A: No. The UG-290/U(40) is rated for 1000 mating cycles, while the Amphenol RF 112511 is rated for 500 mating cycles. The RF Industries RFB-1115-14 does not specify a mating cycle rating. For applications requiring high-cycle reliability, the UG-290/U(40) specification should be referenced.

Q: Are there voltage rating differences?

A: The UG-290/U(40) does not specify a voltage rating. Both substitute parts are rated for 500 V. This additional specification in the substitutes does not create incompatibility.
