Substitute Part Grouping Explanation

Substitution eligibility for the 364A795C is determined by strict equivalence across core RF and mechanical parameters. The substitute part Amphenol RF 031-71046 qualifies as a direct equivalent based on the following critical parameters:

Electrical Equivalence:

• Identical impedance specification: 75 Ohms
• Matching frequency maximum: 1 GHz
• Identical insertion loss: 0.2 dB
• Matching voltage rating: 500 V
• Identical mating cycle rating: 500 cycles

Mechanical Equivalence:

• Identical connector style: BNC
• Identical connector type: Jack, Female Socket
• Identical mounting configuration: Panel Mount, Through Hole, Right Angle
• Identical fastening mechanism: Bayonet Lock
• Matching termination methods: Solder contact and shield termination
• Identical number of ports: 1

Material and Performance Equivalence:

• Center contact material: Phosphor Bronze (both parts)
• Center contact plating: Gold (both parts)
• Dielectric material: Polypropylene (PP) (both parts)
• Body finish: Nickel (both parts)
• Identical features: Board Guide, Isolated

Both parts maintain active product status and comply with international standards (RoHS/ROHS3, EAR99 export classification, identical HTSUS code 8536.69.4010).

Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 031-71046 qualifies as a direct substitute for the Winchester Interconnect 364A795C based on electrical and mechanical parameter equivalence. Both connectors maintain active product status and satisfy international compliance requirements (RoHS/ROHS3, EAR99 classification).

Selection Considerations:

The primary difference between these parts is operating temperature range. The 364A795C operates from -40°C to 165°C, while the 031-71046 operates from -55°C to 85°C. Applications requiring operation above 85°C or below -55°C must use the original 364A795C specification.

Body material differs between the two parts: the 364A795C uses brass construction while the 031-71046 uses zinc die cast. Both materials with nickel finish provide equivalent RF performance and corrosion resistance for the specified electrical parameters.

The 031-71046 is supplied in tray packaging, while the 364A795C packaging specification is not provided. Procurement should confirm packaging compatibility with assembly requirements.

Both parts maintain identical electrical performance: 75 ohm impedance, 1 GHz maximum frequency, 0.2 dB insertion loss, 500 V voltage rating, and 500 mating cycle rating. PCB footprint and through-hole solder pad configuration are mechanically identical for right-angle panel mount applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 031-71046 replace the Winchester Interconnect 364A795C in all applications?

A: The 031-71046 is electrically and mechanically equivalent for RF performance up to 1 GHz at 75 ohms impedance. However, operating temperature range differs. If your application requires operation above 85°C or below -55°C, the original 364A795C must be used. For applications within the -55°C to 85°C range, the 031-71046 is a direct substitute.

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

A: Substitution is determined by equivalence in: connector style (BNC), connector type (Jack, Female Socket), impedance (75 Ohms), mounting configuration (Panel Mount, Through Hole, Right Angle), frequency rating (1 GHz), fastening type (Bayonet Lock), termination method (Solder), and electrical ratings (500 V, 0.2 dB insertion loss, 500 mating cycles). All these parameters are identical between the two parts.

Q: Does the difference in body material (brass vs. zinc die cast) affect RF performance?

A: No. Both materials with nickel finish provide equivalent RF shielding and electrical performance at the specified impedance and frequency. The material difference does not affect insertion loss, impedance, or frequency response within the 1 GHz operating range.

Q: Are there packaging differences I should consider?

A: The 031-71046 is supplied in tray packaging. The 364A795C packaging specification is not provided in the technical data. Confirm packaging compatibility with your assembly process and material handling requirements before procurement.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant (364A795C: RoHS Compliant; 031-71046: ROHS3 Compliant), classified as EAR99 for export control, and share identical HTSUS code 8536.69.4010. The 031-71046 additionally carries REACH Affected status. Both parts have MSL rating of 1 (Unlimited moisture sensitivity).

Q: Can I use these connectors interchangeably on the same PCB?

A: Yes, for applications within the -55°C to 85°C operating temperature range. Both connectors have identical through-hole solder pad configurations for right-angle panel mount applications. No PCB redesign is required for substitution.

Q: What is the maximum frequency these connectors support?

A: Both the 364A795C and 031-71046 support operation up to 1 GHz maximum frequency with 75 ohm impedance and 0.2 dB insertion loss.
