Pomona Electronics 6714 BNC to F Coaxial Adapter

Part Overview

The Pomona Electronics 6714 is a coaxial connector adapter that converts BNC plug (male pin) connections to F jack (female socket) connections. This adapter operates at 75 ohms impedance and is designed for RF applications requiring series conversion between BNC and F connector types.

The 6714 is classified as obsolete. Identifying equivalent substitute parts ensures continued availability for maintenance, repair, and system integration where this adapter specification is required.

Substitute Part Grouping Explanation

Substitute parts for the Pomona Electronics 6714 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

Adapter series conversion: BNC to F
Connector gender configuration: BNC plug (male pin) to F jack (female socket)
Impedance: 75 ohms
Mounting type: Free hanging (in-line)
Fastening mechanism: Bayonet lock, threaded
Style: Straight

Secondary Considerations:

Operating temperature range compatibility
RoHS and regulatory compliance status
Body material and finish specifications
Mating cycle rating

Parts meeting all primary criteria are classified as direct substitutes. Variations in frequency rating, center contact material composition, or dielectric material do not preclude substitution when the primary electrical and mechanical parameters align.

Engineering Selection Recommendations

Pomona Electronics 6779 is the primary substitute for the obsolete Pomona 6714. Both parts are manufactured by Pomona Electronics and share identical mechanical and electrical specifications for adapter conversion, impedance, mounting, and fastening. The 6779 is currently in active production status with higher frequency capability (1.5 GHz versus 500 MHz) and improved center contact material composition (beryllium copper and brass versus brass and phosphor bronze). Both parts maintain ROHS3 compliance and identical operating temperature ranges. The 6779 is available in bulk packaging.

Winchester Interconnect 3318505 provides an alternative substitute from a different manufacturer. This part maintains the same BNC to F adapter series conversion, connector gender configuration, mounting type, and fastening mechanism. The Winchester part is currently active and RoHS compliant. Specific impedance, frequency rating, and operating temperature specifications are not provided for this part number.

Selection between Pomona 6779 and Winchester 3318505 should be based on supply chain requirements, packaging preferences, and any system-level specifications that reference impedance or frequency performance.

Frequently Asked Questions (FAQ)

Q: Can the Pomona 6779 directly replace the obsolete Pomona 6714?

A: Yes. Both parts share identical adapter series conversion (BNC to F), connector gender configuration (BNC plug male to F jack female), impedance (75 ohms), mounting type (free hanging in-line), and fastening mechanism (bayonet lock, threaded). The 6779 is the direct successor with active production status.

Q: What is the difference between the Pomona 6714 and Pomona 6779?

A: The primary differences are product status (6714 is obsolete; 6779 is active), frequency rating (6714 operates to 500 MHz; 6779 operates to 1.5 GHz), and center contact material composition (6714 uses brass and phosphor bronze; 6779 uses beryllium copper and brass). Both maintain 75 ohm impedance and identical mechanical specifications.

Q: Is the Winchester Interconnect 3318505 compatible with systems designed for the Pomona 6714?

A: The Winchester 3318505 maintains the same adapter series conversion, connector gender configuration, mounting type, and fastening mechanism. However, specific impedance and frequency specifications are not provided for this part. Verification against system requirements is necessary before selection.

Q: What packaging options are available for substitute parts?

A: The Pomona 6779 is available in bulk packaging. The Winchester 3318505 packaging specification is not provided. The original Pomona 6714 packaging is not specified.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Pomona 6779 is ROHS3 compliant. The Winchester 3318505 is RoHS compliant. Both meet regulatory requirements for restricted substance use.
