Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 082-4425-1003 are identified based on strict alignment of core electrical and mechanical parameters. The primary substitution criteria include:

Electrical Parameters: Connector style (N Type), connector type (Plug, Male Pin), impedance (50 Ohms), frequency maximum (11 GHz), and voltage rating compatibility.

Mechanical Parameters: Contact termination method (Crimp), shield termination method (Crimp), mounting type (Free Hanging/In-Line), fastening type (Threaded), body material (Brass), body finish (Nickel), and center contact plating (Gold).

Compliance Parameters: RoHS3 compliance and REACH affected status.

Performance Parameters: Mating cycles (500) and operating temperature range.

The Molex 0731000042 qualifies as a substitute based on matching N Type connector style, male pin configuration, 50 Ohm impedance, 11 GHz frequency maximum, crimp shield termination, free hanging mounting, threaded fastening, brass body with nickel finish, gold-plated center contact, 500 mating cycles, RoHS3 compliance, and REACH affected status. Differences in contact termination flexibility (Crimp or Solder versus Crimp only), cable group compatibility, operating temperature range, and voltage rating are noted in the parameter comparison.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0731000042 is an active product with full RoHS3 and REACH compliance, matching the regulatory status of the Amphenol RF 082-4425-1003. Both connectors share identical core RF and mechanical specifications including N Type connector style, 50 Ohm impedance, 11 GHz frequency maximum, crimp shield termination, threaded fastening, and 500 mating cycles.

Selection between these parts depends on application-specific requirements. The Amphenol RF 082-4425-1003 provides higher voltage rating (1500 V versus 1000 V) and extended operating temperature range (-65°C to 165°C versus -55°C to 125°C). The Molex 0731000042 offers flexible contact termination (Crimp or Solder) and compatibility with smaller cable groups (RG-58, 141, 303).

Cable group compatibility must be verified against application requirements. The Amphenol RF part supports larger diameter cables (RG-8 series, RG-9 series, RG-213, RG-214, RG-225, RG-302, RG-393), while the Molex part is specified for smaller diameter cables (RG-58, RG-141, RG-303). Direct substitution is valid only when the application cable group is supported by both connectors or when the substitute cable group is acceptable for the end application.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0731000042 directly replace the Amphenol RF 082-4425-1003 in all applications?

A: Direct replacement is valid when the application cable group is compatible with both connectors. The Amphenol RF part supports RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, and 393 cables, while the Molex part supports RG-58, 141, and 303 cables. Substitution is restricted to applications using RG-58, RG-141, or RG-303 cables. Applications requiring larger cable groups must use the Amphenol RF 082-4425-1003.

Q: What are the voltage rating differences between these connectors?

A: The Amphenol RF 082-4425-1003 is rated for 1500 V, while the Molex 0731000042 is rated for 1000 V. Applications requiring voltage ratings above 1000 V must use the Amphenol RF connector.

Q: How do the operating temperature ranges differ?

A: The Amphenol RF 082-4425-1003 operates from -65°C to 165°C, providing a wider temperature range than the Molex 0731000042, which operates from -55°C to 125°C. Applications requiring operation below -55°C or above 125°C require the Amphenol RF connector.

Q: What is the difference in contact termination between these parts?

A: The Amphenol RF 082-4425-1003 uses crimp termination only. The Molex 0731000042 offers both crimp and solder termination options. Applications requiring solder termination must use the Molex connector.

Q: Are both connectors RoHS3 and REACH compliant?

A: Yes, both the Amphenol RF 082-4425-1003 and Molex 0731000042 are RoHS3 compliant and REACH affected, meeting current regulatory requirements for electronic components.

Q: Do both connectors support the same frequency range?

A: Yes, both connectors are rated for maximum frequency of 11 GHz and maintain 50 Ohm impedance across this range.

Q: What is the mating cycle rating for both connectors?

A: Both connectors are rated for 500 mating cycles, providing equivalent mechanical durability for connection and disconnection operations.
