Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0845250025 is determined by the following critical parameters:

Wire Gauge Compatibility: The main part accommodates 14-18 AWG wire. Substitute parts must support wire gauges within or overlapping this range to ensure proper mechanical and electrical connection.

Contact Configuration: Both the main part and substitutes must be socket contacts to maintain connector interface compatibility.

Contact Material and Finish: Copper alloy construction with appropriate surface finish (tin or nickel) ensures electrical conductivity and corrosion resistance. Finish thickness and material composition affect long-term reliability in the application environment.

Termination Method: The main part uses compression and crimp termination. Substitutes using crimp-only termination remain functionally compatible for wire attachment, as crimp termination is a subset of compression and crimp capability.

Regulatory Compliance: All substitute parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements for the intended application.

The identified substitute, Amphenol Sine Systems Corp AT62-14-0122, meets these criteria with 14-16 AWG wire gauge support, socket configuration, copper alloy construction with nickel finish, crimp termination, and full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol Sine Systems Corp AT62-14-0122 is an active product with current manufacturing support, addressing the obsolescence status of the Molex 0845250025. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for most industrial and commercial applications.

The wire gauge range of the substitute (14-16 AWG) overlaps with the main part specification (14-18 AWG) across the 14-16 AWG range. Applications utilizing 17-18 AWG wire require verification of mechanical fit and electrical performance with the substitute contact geometry.

The contact finish differs between the two parts: tin on the main part versus nickel on the substitute. Both finishes provide adequate corrosion resistance in standard environments. Selection between these finishes depends on specific application requirements regarding contact resistance, environmental exposure, and connector mating cycles.

The termination method on the substitute (crimp only) is compatible with the main part's compression and crimp specification, as crimp termination represents the primary attachment method in both designs.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol AT62-14-0122 directly replace the Molex 0845250025 in all applications?

A: The substitute is compatible for applications using 14-16 AWG wire. Applications requiring 17-18 AWG wire support should evaluate the substitute's mechanical and electrical performance in the specific connector assembly before implementation.

Q: What is the difference between tin and nickel contact finishes?

A: Tin and nickel are both corrosion-resistant finishes for copper alloy contacts. Tin typically offers lower contact resistance, while nickel provides enhanced durability in high-cycle mating environments. Selection depends on application-specific requirements for contact resistance and mating cycle expectations.

Q: Does the crimp-only termination of the substitute affect compatibility?

A: Crimp termination is the standard wire attachment method for both parts. The main part's compression and crimp specification includes crimp as the primary termination mechanism, making the substitute's crimp-only design functionally compatible.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the Molex 0845250025 and Amphenol AT62-14-0122 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for most industrial and commercial applications.

Q: What packaging format is available for the substitute?

A: The Amphenol AT62-14-0122 is supplied in Cut Tape (CT) packaging, suitable for automated assembly processes and component handling.
