BNC Plug to TNC Jack Coaxial Adapter 3315505

Part Overview

The Winchester Interconnect 3315505 is a coaxial adapter connector that converts between BNC plug (male pin) and TNC jack (female socket) interfaces. This adapter operates at 50 ohms impedance and is designed for RF applications requiring series conversion in free-hanging, in-line configurations. The part is currently active in production with 722 units in stock. Equivalent substitute parts may be required due to inventory constraints, application-specific performance requirements, or procurement lead time considerations.

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 Jack)
• Conversion series (BNC to TNC)
• Center gender configuration (Female to Male)
• Impedance (50 Ohms)
• Style (Straight)
• Mounting type (Free Hanging, In-Line)
• Fastening mechanism (Bayonet Lock, Threaded)

Allowable Variation Parameters:

• Frequency maximum rating (higher ratings are acceptable)
• Operating temperature range (wider ranges are acceptable)
• Center contact plating material (Gold or Silver)
• Center contact base material (Brass or Beryllium Copper)
• Dielectric material composition
• RoHS compliance version (RoHS Compliant or ROHS3 Compliant)
• Packaging format (Bulk or standard)

The Amphenol RF part 79025 meets all mandatory matching criteria and demonstrates enhanced performance specifications in frequency rating and temperature range, making it a valid substitute.

Parameter Comparison

Engineering Selection Recommendations

Winchester Interconnect 3315505 is the primary specification part. Selection of this part is appropriate when:

• Original equipment manufacturer (OEM) part number traceability is required
• Procurement specifications explicitly call for Winchester Interconnect components
• Operating conditions remain within -55°C to 100°C range
• Frequency requirements do not exceed 1 GHz

Amphenol RF 79025 is a qualified substitute. Selection of this part is appropriate when:

• Winchester 3315505 inventory is unavailable or subject to extended lead times
• Application frequency requirements extend to 4 GHz
• Operating temperature range must extend to -65°C or above 100°C
• ROHS3 compliance is required (versus RoHS Compliant)
• Higher inventory availability (1212 units) supports procurement timelines

Both parts maintain active product status and carry appropriate regulatory compliance certifications. The mechanical and electrical interface characteristics are identical, ensuring direct substitution without circuit redesign or mechanical rework.

Frequently Asked Questions (FAQ)

Q: Can Amphenol RF 79025 be used as a direct replacement for Winchester 3315505?

A: Yes. Both parts share identical adapter type, connector series conversion (BNC to TNC), center gender configuration, impedance (50 Ohms), style, mounting type, and fastening mechanism. The Amphenol part provides enhanced frequency capability (4 GHz versus 1 GHz) and extended operating temperature range (-65°C to 165°C versus -55°C to 100°C).

Q: What are the differences in center contact materials?

A: Winchester 3315505 uses brass center contacts with gold plating. Amphenol RF 79025 uses beryllium copper center contacts with silver plating. Both configurations maintain 50-ohm impedance and are suitable for RF applications. Material selection affects contact durability and insertion loss characteristics across frequency ranges.

Q: Does packaging format affect electrical performance?

A: No. Winchester 3315505 is supplied in standard packaging, while Amphenol RF 79025 is supplied in bulk packaging. Packaging format does not alter electrical or mechanical specifications. Selection between packaging options depends on procurement quantity requirements and inventory management practices.

Q: Are both parts RoHS compliant?

A: Yes. Winchester 3315505 carries RoHS Compliant certification. Amphenol RF 79025 carries ROHS3 Compliant certification. Both meet regulatory requirements for hazardous substance restrictions. ROHS3 represents a more recent compliance standard revision.

Q: What frequency applications are supported?

A: Winchester 3315505 is rated to 1 GHz maximum frequency. Amphenol RF 79025 is rated to 4 GHz maximum frequency. Application frequency requirements determine which part is appropriate. Applications exceeding 1 GHz require the Amphenol substitute.

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

A: Winchester 3315505 operates from -55°C to 100°C. Amphenol RF 79025 operates from -65°C to 165°C. Applications requiring operation above 100°C or below -55°C require the Amphenol RF substitute.
