Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0845250053 is determined by the following critical parameters:

• Socket Contact Type: Both main and substitute parts must function as socket contacts for mating with pin contacts
• Wire Gauge Compatibility: The substitute must accommodate the specified wire gauge range. The Molex part accepts 16-20 AWG; the substitute accepts 18-20 AWG, providing overlap in the 18-20 AWG range
• Contact Material: Copper alloy base material is maintained across both parts for electrical conductivity and mechanical durability
• Termination Method: Both parts utilize crimp termination, ensuring compatibility with standard crimping tools and processes
• Compliance Standards: Both parts meet ROHS3 compliance and maintain MSL 1 rating, suitable for unrestricted moisture environments
• Contact Finish: The Molex part features tin plating; the substitute features nickel plating. Both finishes provide corrosion resistance and are acceptable for power contact applications

The Amphenol Sine Systems Corp AT62-16-0622 qualifies as a substitute within the overlapping wire gauge specification (18-20 AWG) and maintains equivalent electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol Sine Systems Corp AT62-16-0622 is an active product with current manufacturing support, addressing the obsolescence status of the Molex 0845250053. Both parts maintain ROHS3 compliance and MSL 1 ratings, ensuring regulatory and environmental compatibility.

The wire gauge overlap (18-20 AWG) permits substitution for applications utilizing 18-20 AWG conductors. Applications requiring 16 AWG wire termination must source alternative contacts that support the full 16-20 AWG range.

Both parts employ copper alloy base material with surface finishes (tin and nickel respectively) that provide equivalent corrosion resistance for power contact applications. The contact finish difference does not preclude substitution from an electrical performance standpoint.

The Amphenol part is supplied in Cut Tape packaging, suitable for automated assembly processes and component management systems.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol AT62-16-0622 directly replace the Molex 0845250053 in all applications?

A: Substitution is valid for applications using 18-20 AWG wire gauges. Applications requiring 16 AWG termination capability must identify alternative contacts supporting the full 16-20 AWG specification.

Q: What is the significance of the contact finish difference (tin vs. nickel)?

A: Both tin and nickel finishes provide corrosion resistance suitable for power contact applications. The finish difference does not impact electrical conductivity or mechanical performance within the specified operating parameters.

Q: Are both parts suitable for the same connector series?

A: The Molex part is specified for ML-XT and XRC series connectors. The Amphenol part is specified for ASeries™ connectors. Physical compatibility with existing connector housings must be verified based on contact geometry and mating interface specifications.

Q: What packaging considerations apply to the substitute part?

A: The Amphenol AT62-16-0622 is supplied in Cut Tape packaging, standard for automated pick-and-place assembly. The original Molex part packaging is not specified in available documentation.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 ratings. Both are classified under ECCN EAR99 and HTSUS 8536.90.4000, meeting equivalent regulatory requirements.
