Winchester Interconnect 1313505 Coaxial Connector Adapter - Equivalent & Substitute Parts

Part Overview

The Winchester Interconnect 1313505 is an N Plug to BNC Jack coaxial connector adapter designed for RF applications requiring conversion between N-series and BNC-series connectors. This straight-style, free-hanging adapter features a male pin center contact converting to a female socket configuration, with bayonet lock and threaded fastening. The part is actively manufactured and maintains 1137 units in current inventory stock.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for coaxial connector adapters is determined by strict alignment of mechanical and electrical interface parameters. The following criteria establish substitution validity:

Primary Substitution Criteria:

• Adapter type (Plug to Jack)
• Conversion type (Between Series)
• Adapter series (BNC to N)
• Center gender configuration (Female to Male)
• Convert from specification (N Plug, Male Pin)
• Convert to specification (BNC Jack, Female Socket)
• Style (Straight)
• Mounting type (Free Hanging, In-Line)
• Fastening type (Bayonet Lock, Threaded)
• Body material (Brass)
• Body finish (Nickel)

The Pomona Electronics part number 3288 satisfies all primary substitution criteria, establishing it as a direct equivalent to the Winchester Interconnect 1313505 within the coaxial connector adapter category.

Parameter Comparison

Engineering Selection Recommendations

Both the Winchester Interconnect 1313505 and Pomona Electronics 3288 are actively manufactured products with current inventory availability. Selection between these parts is based on the following engineering considerations:

Winchester Interconnect 1313505:

• Higher current inventory (1137 units)
• RoHS Compliant certification
• MSL rating of 1 (Unlimited moisture sensitivity)
• Suitable for applications where specific material specifications are not constrained

Pomona Electronics 3288:

• ROHS3 Compliant certification (enhanced environmental compliance)
• Specified impedance of 50 Ohms
• Gold-plated center contact with Beryllium Copper material
• PTFE dielectric material specified
• Operating temperature range: -65°C to 165°C
• REACH Unaffected status
• Suitable for applications requiring defined electrical performance and extended temperature operation

Both parts share identical mechanical interface specifications and fastening characteristics. The Pomona 3288 provides additional electrical specification detail and enhanced compliance documentation. Selection should be based on application requirements for impedance specification, temperature range, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the Pomona 3288 directly replace the Winchester 1313505 in existing designs?

A: Yes. Both adapters share identical mechanical interface specifications: N Plug male pin to BNC Jack female socket configuration, straight style, free-hanging mounting, and bayonet lock/threaded fastening. The Pomona 3288 provides additional electrical specifications (50 Ohm impedance, PTFE dielectric) not detailed in the Winchester part documentation.

Q: What is the significance of the 50 Ohm impedance specification on the Pomona 3288?

A: The 50 Ohm impedance is a standard RF characteristic for coaxial connectors in telecommunications and RF applications. This specification is provided for the Pomona part but not documented for the Winchester part. Applications requiring impedance-matched RF systems should reference the Pomona 3288 specification.

Q: Are there packaging differences between these adapters?

A: The Winchester 1313505 packaging is not specified in available documentation. The Pomona 3288 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

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

A: ROHS3 represents the third iteration of the Restriction of Hazardous Substances directive with updated restricted substance lists. Both certifications indicate compliance with hazardous substance restrictions; ROHS3 represents the current regulatory standard.

Q: Can these adapters be used in high-temperature applications?

A: The Pomona 3288 specifies an operating temperature range of -65°C to 165°C. The Winchester 1313505 does not provide operating temperature documentation. Applications requiring defined temperature performance should specify the Pomona 3288.

Q: What does MSL 1 (Unlimited) mean for the Winchester part?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without special moisture control measures during storage and handling. The Pomona 3288 lists MSL as Not Applicable, indicating no moisture sensitivity constraints.

Q: Are both parts currently in stock?

A: Yes. The Winchester 1313505 has 1137 units in current inventory. The Pomona 3288 has 816 units in current inventory. Both are actively manufactured products.
