Engineering Selection Recommendations

The Molex 0731010120 serves as a direct functional equivalent to the obsolete Amphenol ICC 456-717G for new designs and component replacement applications. Selection of the Molex substitute is supported by the following factors:

Product Status: The Molex 0731010120 maintains active product status with significantly higher inventory availability (12,852 units versus 679 units), ensuring long-term supply chain continuity.

Regulatory Compliance: Both components meet RoHS requirements. The Molex part carries ROHS3 compliance certification, representing current regulatory standards. The Molex component also carries REACH unaffected status and EAR99 ECCN classification.

Electrical and Mechanical Equivalence: All critical parameters for RF coaxial connector functionality are identical between the two parts, including impedance rating, termination methods, mounting configuration, and mating cycle specifications.

Material Specifications: While the Molex part uses zinc alloy versus zinc die cast for the body material, both employ nickel finish and maintain equivalent mechanical and environmental performance within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0731010120 be used as a direct replacement for the Amphenol ICC 456-717G in existing designs?

A: Yes. Both components share identical electrical specifications (75 ohm impedance, BNC connector style, female socket configuration) and mechanical mounting parameters (panel mount, through hole, right angle, solder termination). The components are mechanically and electrically interchangeable.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer identity, product status (obsolete versus active), and material composition. The Amphenol ICC part uses zinc die cast body material while the Molex part uses zinc alloy. Both employ nickel finish. The Molex component offers superior inventory availability and current regulatory compliance certifications.

Q: Are there any compatibility concerns with PCB layout or mounting?

A: No. Both components specify identical mounting configurations: panel mount, through hole, right angle with bulkhead front side nut. PCB footprints and mounting hole patterns are equivalent.

Q: What is the significance of the different center contact materials?

A: The Amphenol ICC part specifies copper alloy with tin plating, while the Molex part specifies phosphor bronze with gold plating. Both materials provide adequate electrical conductivity and contact reliability for 75 ohm RF applications at the specified voltage rating (200 V) and mating cycle count (500 cycles).

Q: Does the packaging difference affect component selection?

A: The Molex 0731010120 is supplied in bag packaging, while the Amphenol ICC part packaging is not specified. This difference does not affect electrical or mechanical performance and relates only to logistics and handling procedures.

Q: Are both components RoHS compliant?

A: Yes. The Amphenol ICC 456-717G is RoHS compliant. The Molex 0731010120 carries ROHS3 compliance, which represents the current iteration of RoHS requirements and includes additional restricted substances.
