Winchester Interconnect 3317505 BNC to UHF Coaxial Adapter Connector

Part Overview

The Winchester Interconnect 3317505 is an RF coaxial adapter connector that converts between BNC Plug (Male Pin) and UHF Jack (Female Socket) configurations. This adapter operates at 50 Ohms impedance and is designed for in-line, free-hanging applications requiring bayonet lock and threaded fastening. The part maintains Active product status and is RoHS Compliant, with 1079 units currently in stock as new original inventory.

Equivalent and substitute parts are identified when alternative manufacturers provide coaxial adapters with matching or compatible electrical and mechanical specifications for BNC to UHF conversion applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Winchester Interconnect 3317505 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or remain compatible for substitution:

Critical Matching Parameters:

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

Compatible Variation Parameters:

• Impedance: 50 Ohms (primary specification); Non-Constant impedance represents a deviation
• Frequency maximum: 1 GHz or higher
• Operating temperature range: Must encompass or exceed -55°C ~ 100°C
• Body and contact materials: Brass or equivalent conductive materials
• Center contact plating: Gold
• RoHS compliance status: RoHS Compliant or ROHS3 Compliant

Two substitute parts meet the critical matching criteria: Amphenol RF 242134 and Pomona Electronics 3287.

Parameter Comparison

Engineering Selection Recommendations

Amphenol RF 242134 is a direct substitute for the Winchester Interconnect 3317505 when higher frequency capability is required. Both parts maintain 50 Ohms impedance, identical mechanical configuration, and equivalent RoHS compliance. The Amphenol RF 242134 provides extended operating temperature range (-65°C ~ 165°C versus -55°C ~ 100°C) and higher frequency maximum (2.5 GHz versus 1 GHz). Center contact material differs (Phosphor Bronze versus Brass), and dielectric material is specified as PTFE. Both parts are Active status with substantial inventory availability.

Pomona Electronics 3287 meets the mechanical and connector configuration requirements but operates with Non-Constant impedance specification, which deviates from the 50 Ohms standard of the primary part. This part is suitable only for applications where impedance matching is not critical. Operating temperature range is more limited (-55°C ~ 85°C). Pomona Electronics 3287 is Active status with 1005 units in inventory.

Selection between Winchester Interconnect 3317505 and Amphenol RF 242134 depends on frequency and temperature requirements of the specific application. Selection of Pomona Electronics 3287 requires confirmation that Non-Constant impedance is acceptable for the intended circuit.

Frequently Asked Questions (FAQ)

Q: Can Amphenol RF 242134 directly replace Winchester Interconnect 3317505 in all applications?

A: Amphenol RF 242134 is mechanically and electrically compatible for BNC to UHF adapter applications. Both maintain 50 Ohms impedance, identical connector configurations, and equivalent RoHS compliance. The Amphenol part provides higher frequency capability (2.5 GHz versus 1 GHz) and extended temperature range. Substitution is valid when these enhanced specifications do not conflict with application requirements.

Q: What is the significance of the Non-Constant impedance specification in Pomona Electronics 3287?

A: Non-Constant impedance indicates that the adapter does not maintain a uniform 50 Ohms characteristic impedance throughout its transmission path. This specification is acceptable only in applications where impedance matching is not required or where signal integrity is not critical. For RF applications requiring controlled impedance, Winchester Interconnect 3317505 or Amphenol RF 242134 are appropriate selections.

Q: Are there packaging differences between these three adapter parts?

A: Winchester Interconnect 3317505 packaging is not specified. Amphenol RF 242134 is supplied in Bag packaging. Pomona Electronics 3287 is supplied in Bulk packaging. Packaging format may affect inventory management and handling procedures but does not alter electrical or mechanical compatibility.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. RoHS Compliant refers to the original RoHS Directive. ROHS3 Compliant refers to the updated RoHS Directive 2011/65/EU. Both statuses confirm that the parts meet hazardous substance restrictions and are suitable for regulated applications.

Q: How do operating temperature ranges affect part selection?

A: Winchester Interconnect 3317505 operates from -55°C to 100°C. Amphenol RF 242134 operates from -65°C to 165°C, providing wider temperature coverage. Pomona Electronics 3287 operates from -55°C to 85°C, with a more limited upper temperature limit. Selection depends on the thermal environment of the application. For applications exceeding 100°C, Amphenol RF 242134 is required.

Q: Do center contact material differences affect performance?

A: Winchester Interconnect 3317505 uses Brass center contacts. Both substitute parts use Phosphor Bronze center contacts. Both materials are conductive and suitable for RF applications. Material selection affects mechanical properties and durability characteristics but does not alter electrical performance for the specified frequency ranges.
