Pomona Electronics 6716 Coaxial Connector Adapter

Part Overview

The Pomona Electronics 6716 is an F plug to BNC jack coaxial connector adapter designed for RF applications requiring impedance matching at 75 Ohms. This adapter converts between F series and BNC series connectors with a straight, free-hanging configuration suitable for in-line applications.

The 6716 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications currently utilizing this adapter.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Pomona Electronics 6716 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Adapter type: Plug to Jack
• Adapter series: BNC to F
• Convert from: F Plug, Male Pin
• Convert to: BNC Jack, Female Socket
• Style: Straight
• Mounting type: Free Hanging (In-Line)
• Fastening type: Bayonet Lock, Threaded

Secondary Compatibility Factors:

• Impedance (75 Ohms preferred for direct substitution)
• Frequency maximum rating
• Operating temperature range
• Product status (Active preferred over Obsolete)

Two substitute parts meet the primary matching criteria. The Pomona Electronics 6781 maintains identical impedance (75 Ohms) and represents a direct functional replacement. The Winchester Interconnect 8313505 operates at 50 Ohms impedance and extends frequency capability to 1 GHz, suitable for applications where impedance conversion or higher frequency operation is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Pomona Electronics 6781 is the primary substitute for the Pomona 6716. Both parts maintain identical impedance (75 Ohms), matching connector series, and operating temperature range. The 6781 is currently in active production status with higher frequency capability (1.5 GHz versus 500 MHz), providing enhanced performance margin. Both parts carry ROHS3 compliance certification.

Winchester Interconnect 8313505 serves as an alternative substitute when 50 Ohm impedance is acceptable within the application circuit design. This part extends the operating temperature range to -55°C ~ 100°C and provides 1 GHz frequency capability. Selection of this part requires confirmation that 50 Ohm impedance does not introduce signal reflection or impedance mismatch issues in the target application.

Frequently Asked Questions (FAQ)

Q: Can the Pomona 6781 directly replace the Pomona 6716?

A: Yes. Both parts share identical mechanical configuration, impedance (75 Ohms), connector series (BNC to F), and operating temperature range. The 6781 is in active production and offers superior frequency performance (1.5 GHz).

Q: What is the impedance difference between the Pomona 6781 and Winchester 8313505?

A: The Pomona 6781 operates at 75 Ohms, matching the original 6716 specification. The Winchester 8313505 operates at 50 Ohms. Selection depends on whether the application circuit is designed for 75 Ohm or 50 Ohm impedance matching.

Q: Are all three parts mechanically compatible?

A: Yes. All three parts feature identical adapter type (Plug to Jack), connector series (BNC to F), style (Straight), mounting type (Free Hanging), and fastening type (Bayonet Lock, Threaded).

Q: What is the frequency limitation of the original Pomona 6716?

A: The Pomona 6716 is rated to 500 MHz maximum frequency. Both substitute parts exceed this specification, with the Pomona 6781 rated to 1.5 GHz and the Winchester 8313505 rated to 1 GHz.

Q: Does the Winchester 8313505 require different handling or storage?

A: The Winchester 8313505 carries MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions. Standard handling procedures for coaxial connectors apply.
