Equivalent & Substitute Parts for Winchester Interconnect 831B509

Part Overview

The Winchester Interconnect 831B509 is an F-series coaxial adapter connector designed to convert F Plug (male pin) to F Jack (female socket) configurations. This straight-style, free-hanging adapter operates at frequencies up to 500 MHz and is constructed with brass body and nickel finish components. The part is actively manufactured and maintains 1165 units in current inventory stock.

Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable, while maintaining equivalent electrical and mechanical performance within the specified parameter constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 831B509 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Adapter Type: Plug to Jack
• Adapter Series: F to F
• Center Gender: Female to Male
• Convert From: F Plug, Male Pin
• Convert To: F Jack, Female Socket
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Frequency - Max: 500 MHz or greater
• Body Material: Brass
• Body Finish: Nickel

Acceptable Variations:

• Impedance specification (main part is non-constant; substitute may specify 75 Ohms)
• Dielectric material composition
• Fastening type configuration
• Center contact plating
• Operating temperature range
• Mating cycle rating
• Packaging format

The Pomona Electronics 6713 qualifies as a substitute based on matching all critical parameters while providing defined impedance (75 Ohms) and enhanced mechanical specifications.

Engineering Selection Recommendations

Primary Part Selection (Winchester 831B509):

• Select when RoHS Compliant certification is required
• Suitable for applications where impedance specification is not critical
• Recommended for standard F-series coaxial adapter applications up to 500 MHz
• Active product status ensures continued availability and support

Substitute Part Selection (Pomona Electronics 6713):

• Select when 75 Ohm impedance specification is required for the application
• ROHS3 Compliant status meets enhanced environmental compliance requirements
• Specified operating temperature range (-40°C ~ 65°C) supports extended environmental applications
• Defined mating cycle rating (500 cycles) provides mechanical durability specification
• Bulk packaging format accommodates high-volume procurement requirements
• Snap-On fastening option provides alternative mechanical interface configuration

Both parts maintain active product status and current inventory availability. Selection between primary and substitute should be based on specific application impedance requirements and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the Pomona Electronics 6713 directly replace the Winchester 831B509 in all applications?

A: The 6713 qualifies as a substitute based on matching adapter type, series, gender configuration, style, mounting type, and frequency rating. The primary difference is impedance specification: the 831B509 is non-constant impedance while the 6713 is specified at 75 Ohms. Substitution is valid when 75 Ohm impedance is compatible with the application requirements.

Q: What is the significance of the impedance difference between these parts?

A: The Winchester 831B509 does not specify a constant impedance value, while the Pomona 6713 is rated at 75 Ohms. In coaxial adapter applications, impedance affects signal transmission characteristics. The 75 Ohm specification of the 6713 is suitable for standard video and RF applications. Verify that 75 Ohm impedance is acceptable for your specific application before substitution.

Q: Are there packaging differences between these parts?

A: Yes. The Winchester 831B509 packaging is not specified in the available data. The Pomona 6713 is supplied in Bulk packaging format. Confirm packaging requirements for your procurement and inventory management processes.

Q: Do both parts meet RoHS compliance requirements?

A: Both parts are RoHS compliant. The Winchester 831B509 carries RoHS Compliant certification. The Pomona 6713 carries ROHS3 Compliant certification, which represents an enhanced compliance standard. Both are acceptable for RoHS-regulated applications.

Q: What is the operating temperature range for these adapters?

A: The Winchester 831B509 does not specify an operating temperature range in the available data. The Pomona 6713 specifies -40°C ~ 65°C operating temperature. If your application requires operation outside standard temperature ranges, the Pomona 6713 provides documented thermal specifications.

Q: How do the fastening types differ?

A: The Winchester 831B509 uses Threaded fastening on both ends. The Pomona 6713 uses Snap-On fastening on one end and Threaded fastening on the other end. This difference affects the mechanical connection method but does not impact electrical performance for equivalent F-series adapter applications.

Q: Is the Pomona 6713 suitable for high-cycle mating applications?

A: The Pomona 6713 specifies 500 mating cycles. The Winchester 831B509 does not provide a mating cycle specification. If your application involves frequent connector mating and unmatting, the documented 500-cycle rating of the 6713 provides a defined mechanical durability specification.
