Pomona Electronics 6706 Coaxial Connector Adapter - Equivalent & Substitute Parts

Part Overview

The Pomona Electronics 6706 is an F-type coaxial connector adapter designed for 75-ohm RF applications. This adapter provides jack-to-jack (female socket to female socket) connectivity with panel mount bulkhead configuration and straight orientation. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Pomona Electronics 6706 is determined by the following critical parameters:

Primary Substitution Criteria (Must Match):

• Adapter Type: Jack to Jack
• Adapter Series: F to F
• Center Gender: Female to Female
• Mounting Type: Panel Mount with Bulkhead feature
• Fastening Type: Threaded connections

Secondary Compatibility Parameters (Allowable Variation):

• Impedance: 75 Ohms (primary specification)
• Style: Straight orientation
• Frequency - Max: Must support minimum 500 MHz operation
• Operating Temperature: Must encompass or exceed -40°C ~ 65°C range
• RoHS Compliance: ROHS3 or equivalent regulatory compliance

The substitute parts listed below meet the primary substitution criteria. Variations in secondary parameters are noted to enable informed selection based on specific application requirements.

Engineering Selection Recommendations

Primary Substitute: Amphenol RF 222121

The Amphenol RF 222121 is the most direct functional equivalent to the Pomona Electronics 6706. Both parts maintain identical adapter type (jack-to-jack), adapter series (F to F), center gender (female to female), mounting configuration (panel mount bulkhead), and fastening type (threaded). The 222121 provides enhanced frequency capability (2 GHz versus 500 MHz) and extended operating temperature range (-55°C ~ 85°C versus -40°C ~ 65°C), making it suitable for applications requiring the original 6706 specifications. Both parts are ROHS3 compliant. The 222121 is currently in active production with substantial inventory availability.

Secondary Substitutes: Winchester Interconnect 832A519N and 851A509

The Winchester Interconnect 832A519N maintains jack-to-jack adapter type, F-to-F series, female-to-female center gender, panel mount bulkhead configuration, and threaded fastening. However, impedance is specified as non-constant rather than 75 ohms, and operating temperature range is not provided. This part is suitable only for applications where 75-ohm impedance is not a critical requirement.

The Winchester Interconnect 851A509 differs significantly in adapter type (plug-to-jack rather than jack-to-jack), center gender (female-to-male rather than female-to-female), style (right angle rather than straight), and mounting type (free hanging in-line rather than panel mount bulkhead). This part is not a direct substitute for the Pomona 6706 and should be selected only when the specific mechanical and electrical configuration of the 851A509 is required.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 222121 directly replace the Pomona Electronics 6706 in existing installations?

A: Yes. The 222121 matches all primary substitution criteria: jack-to-jack adapter type, F-to-F series, female-to-female center gender, panel mount bulkhead mounting, and threaded fastening. The 222121 provides superior frequency performance (2 GHz) and extended temperature range (-55°C ~ 85°C), making it functionally compatible with applications designed for the 6706.

Q: What is the significance of impedance specification in coaxial connector adapter selection?

A: Impedance determines signal transmission characteristics in RF systems. The Pomona 6706 and Amphenol RF 222121 are both specified at 75 ohms, which is the standard impedance for video and composite RF applications. The Winchester parts (832A519N and 851A509) specify non-constant impedance, indicating they are not optimized for 75-ohm systems and should not be used as direct replacements in impedance-critical applications.

Q: Are there packaging differences between the substitute parts?

A: The Pomona 6706 packaging is not specified. The Amphenol RF 222121 is supplied in bag packaging. The Winchester parts do not specify packaging type. Packaging differences do not affect functional compatibility but may impact inventory management and handling procedures.

Q: What compliance certifications apply to these parts?

A: The Pomona 6706 and Amphenol RF 222121 are both ROHS3 compliant. The Winchester parts (832A519N and 851A509) are RoHS compliant. All parts are classified under ECCN EAR99 and HTSUS 8536.69.4010. The Amphenol RF 222121 is REACH affected; the Pomona 6706 is REACH unaffected.

Q: Why is the Winchester 851A509 listed if it does not match the primary adapter type?

A: The 851A509 is included for reference purposes only. It differs in adapter type (plug-to-jack), center gender (female-to-male), style (right angle), and mounting type (free hanging in-line). This part should be selected only when the specific mechanical and electrical configuration differs from the Pomona 6706 requirements.
