The substitute part Amphenol RF 031-71046 meets all mandatory electrical and mechanical compatibility criteria for direct substitution in PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Winchester Interconnect 364A795CT and Amphenol RF 031-71046 are active products with full regulatory compliance. The 364A795CT carries RoHS Compliant certification, while the 031-71046 carries ROHS3 Compliant certification, indicating enhanced environmental compliance standards. The 031-71046 additionally carries REACH Affected status.

Selection between these parts should be based on:

Availability and Lead Time: The 031-71046 (Amphenol RF) has 932 pieces in stock versus 885 pieces for the 364A795CT (Winchester Interconnect).

Operating Temperature Range: The 364A795CT operates from -40°C to 165°C, while the 031-71046 operates from -55°C to 85°C. Applications requiring extended high-temperature operation favor the 364A795CT. Applications requiring extended low-temperature operation favor the 031-71046.

Body Material Differences: The 364A795CT uses brass body material with nickel finish. The 031-71046 uses zinc die cast body material with nickel finish. Both materials provide equivalent RF performance at the specified frequency and impedance.

Housing Color: The 031-71046 is available in black and silver options, while the 364A795CT does not specify housing color options.

Packaging: The 031-71046 is supplied in tray packaging, while the 364A795CT packaging is not specified.

Both connectors meet all electrical and mechanical requirements for direct PCB substitution in 75 ohm RF applications up to 1 GHz.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 031-71046 directly replace the Winchester Interconnect 364A795CT on existing PCBs?

A: Yes. Both connectors share identical electrical specifications (75 ohms, 1 GHz maximum frequency, 500 V rating, 0.2 dB insertion loss), identical mechanical mounting configuration (panel mount, through-hole, right angle, bulkhead), and identical termination methods (solder contact and shield). PCB footprints and hole patterns are compatible for direct substitution.

Q: What is the primary difference between these two connectors?

A: The primary differences are operating temperature range and body material composition. The 364A795CT operates from -40°C to 165°C with brass body construction. The 031-71046 operates from -55°C to 85°C with zinc die cast body construction. Both achieve identical RF performance at the specified impedance and frequency.

Q: Are there any compliance or certification differences?

A: The 364A795CT carries RoHS Compliant certification. The 031-71046 carries ROHS3 Compliant certification and REACH Affected status. ROHS3 represents a more recent compliance standard. Both connectors carry EAR99 export classification and 8536.69.4010 HTSUS code.

Q: Which connector should be selected for high-temperature applications?

A: The Winchester Interconnect 364A795CT is rated to 165°C maximum operating temperature, compared to 85°C for the Amphenol RF 031-71046. For applications exceeding 85°C, the 364A795CT is the appropriate selection.

Q: Which connector should be selected for low-temperature applications?

A: The Amphenol RF 031-71046 is rated to -55°C minimum operating temperature, compared to -40°C for the Winchester Interconnect 364A795CT. For applications below -40°C, the 031-71046 is the appropriate selection.

Q: Are the mating cycles and insertion loss specifications identical?

A: Yes. Both connectors specify 500 mating cycles and 0.2 dB insertion loss, indicating equivalent mechanical durability and RF performance characteristics.

Q: What packaging options are available?

A: The Amphenol RF 031-71046 is supplied in tray packaging. The Winchester Interconnect 364A795CT packaging specification is not provided in the technical data.

Q: Do both connectors include board guide and isolated features?

A: Yes. Both the 364A795CT and 031-71046 include board guide and isolated features for PCB mounting applications.
