Pomona Electronics 6715 BNC to F Jack Coaxial Adapter

Part Overview

The Pomona Electronics 6715 is a coaxial connector adapter designed to convert between BNC Jack (female socket) and F Jack (female socket) configurations. This adapter operates at 75 Ohms impedance and supports frequencies up to 500 MHz. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs requiring this connector conversion functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Pomona Electronics 6715 is determined by the following critical parameters:

Primary Matching Criteria:

• Adapter series configuration (BNC Jack to F Jack)
• Center gender (Female to Female)
• Connector type (Jack to Jack)
• Mounting style (Free Hanging, In-Line)
• Fastening mechanism (Bayonet Lock, Threaded)

Secondary Compatibility Factors:

• Impedance rating (75 Ohms preferred for direct substitution)
• Maximum frequency capability (must meet or exceed application requirements)
• Operating temperature range (must encompass intended use conditions)
• Regulatory compliance (RoHS and REACH status)

The substitute parts identified maintain the core adapter functionality while offering variations in frequency response, impedance, and material composition. Selection depends on specific system impedance requirements and frequency bandwidth needs.

Parameter Comparison

Engineering Selection Recommendations

Pomona Electronics 6780 is the primary substitute for the obsolete Pomona 6715. Both parts share identical impedance (75 Ohms), connector configuration, and operating temperature range. The 6780 offers enhanced frequency capability (1.5 GHz versus 500 MHz) and maintains active product status with ROHS3 compliance. This part is recommended for direct replacement in 75 Ohm systems.

Winchester Interconnect 3328505 serves as an alternative for applications operating at 50 Ohms impedance. This part provides extended frequency bandwidth (1 GHz) and wider operating temperature range (-55°C ~ 100°C). Selection of this part requires system impedance compatibility verification, as it operates at 50 Ohms rather than the original 75 Ohms specification.

Both substitute parts maintain the same physical connector configuration (BNC Jack female to F Jack female), mounting style, and fastening mechanism as the original part. Product status and regulatory compliance certifications support long-term availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the Pomona 6780 directly replace the Pomona 6715? A: Yes. Both parts maintain identical impedance (75 Ohms), connector gender configuration (female to female), and adapter series (BNC to F). The 6780 is active production status and ROHS3 compliant, making it suitable for direct substitution in existing designs.

Q: What is the impedance difference between the Pomona 6780 and Winchester 3328505? A: The Pomona 6780 operates at 75 Ohms, while the Winchester 3328505 operates at 50 Ohms. Selection depends on system impedance requirements. Impedance mismatch can result in signal reflections and performance degradation.

Q: Are all substitute parts compatible with the same mounting configuration? A: Yes. All listed parts use free hanging, in-line mounting with bayonet lock and threaded fastening mechanisms, maintaining mechanical compatibility with the original part.

Q: What frequency bandwidth differences exist among these adapters? A: The Pomona 6715 supports up to 500 MHz, the Pomona 6780 supports up to 1.5 GHz, and the Winchester 3328505 supports up to 1 GHz. Selection should match or exceed application frequency requirements.

Q: Do all parts meet current regulatory compliance standards? A: The Pomona 6780 and Winchester 3328505 are both RoHS compliant. The Pomona 6715 is ROHS3 compliant but obsolete. For new designs, active production parts (6780 or 3328505) are recommended.

Q: What is the operating temperature range difference? A: The Pomona parts (6715 and 6780) operate from -40°C to 65°C. The Winchester 3328505 operates from -55°C to 100°C, providing extended temperature capability for demanding environments.
