Winchester Interconnect 5309505 Coaxial Adapter - Equivalent & Substitute Parts

Part Overview

The Winchester Interconnect 5309505 is an RF coaxial adapter connector designed to convert between TNC Plug (Male Pin) and SMA Plug (Male Pin) interfaces. This adapter operates at 50 Ohms impedance and is rated for frequencies up to 1 GHz. The part is currently Active in product status with 711 units in stock. Coaxial adapter connectors require substitutes when original inventory is unavailable, when alternative performance specifications are required for specific applications, or when supply chain constraints necessitate equivalent component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for coaxial adapter connectors is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Plug to Plug
• Conversion Type: Between Series
• Adapter Series: SMA to TNC
• Center Gender: Male to Male
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded, Threaded

Allowable Variation Parameters:

• Frequency - Max: May exceed the original specification
• Operating Temperature Range: May exceed the original specification
• Body Material and Finish: May differ while maintaining electrical performance
• Center Contact Plating: May differ while maintaining electrical performance
• RoHS/Compliance Status: Must maintain or exceed compliance level

The Pomona Electronics 4292 satisfies all mandatory matching parameters and provides enhanced performance specifications in frequency and temperature range, making it a valid substitute for the Winchester Interconnect 5309505.

Engineering Selection Recommendations

Winchester Interconnect 5309505 Selection Criteria:

• Applications requiring TNC Plug input with SMA Plug output conversion
• Operating frequency up to 1 GHz
• Temperature range -55°C to 100°C
• RoHS Compliant requirement
• Brass body with nickel finish specification
• Active product status with established supply chain

Pomona Electronics 4292 Selection Criteria:

• Applications requiring SMA Plug input with TNC Plug output conversion (reversed orientation)
• Operating frequency up to 12.4 GHz
• Temperature range -65°C to 165°C
• ROHS3 Compliant requirement
• Beryllium Copper body with gold finish specification
• Enhanced performance specifications beyond original part requirements

Critical Note on Orientation: The Pomona Electronics 4292 reverses the conversion direction. The Winchester 5309505 converts FROM TNC TO SMA, while the Pomona 4292 converts FROM SMA TO TNC. Both parts are mechanically and electrically compatible for the same connector pair interface, but the input/output ends are reversed. Selection depends on which connector type is the source and which is the destination in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the Pomona Electronics 4292 be used as a direct replacement for the Winchester Interconnect 5309505?

A: The Pomona Electronics 4292 is electrically and mechanically compatible with the Winchester Interconnect 5309505 for the same connector pair (SMA and TNC). However, the conversion direction is reversed. The Winchester 5309505 converts TNC input to SMA output, while the Pomona 4292 converts SMA input to TNC output. Both parts function identically in terms of impedance, gender, and mechanical interface, but the source and destination connectors are swapped. Verify your application's connector orientation before selection.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: Adapter Type (Plug to Plug), Conversion Type (Between Series), Adapter Series (SMA to TNC), Center Gender (Male to Male), Impedance (50 Ohms), Style (Straight), Mounting Type (Free Hanging In-Line), and Fastening Type (Threaded, Threaded). All substitute parts must match these parameters exactly.

Q: Does the Pomona Electronics 4292 support higher frequencies than the Winchester 5309505?

A: Yes. The Pomona Electronics 4292 is rated for frequencies up to 12.4 GHz, compared to the Winchester Interconnect 5309505 rated at 1 GHz. The Pomona part provides enhanced frequency performance and is suitable for applications requiring higher bandwidth operation.

Q: What is the difference in operating temperature range between these parts?

A: The Winchester Interconnect 5309505 operates from -55°C to 100°C. The Pomona Electronics 4292 operates from -65°C to 165°C, providing a wider temperature range suitable for more extreme environmental conditions.

Q: Are both parts RoHS compliant?

A: Yes. The Winchester Interconnect 5309505 is RoHS Compliant. The Pomona Electronics 4292 is ROHS3 Compliant, which represents a higher compliance standard. Both parts meet RoHS requirements.

Q: What packaging is available for the Pomona Electronics 4292?

A: The Pomona Electronics 4292 is supplied in Bulk packaging, compared to the Winchester Interconnect 5309505 which does not specify packaging type. Verify packaging requirements for your procurement process.

Q: How do the body materials differ between these adapters?

A: The Winchester Interconnect 5309505 uses Brass body with Nickel finish. The Pomona Electronics 4292 uses Beryllium Copper body with Gold finish. Both materials provide adequate RF performance and shielding for 50 Ohm coaxial applications. Material selection may depend on environmental exposure, corrosion resistance requirements, or specific application standards.
