Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0002091139 is determined by the following critical parameters:

• Contact Type: Socket configuration for mating with pin contacts
• Termination Method: Crimp termination for wire attachment
• Contact Finish: Tin plating at 20.0µin (0.51µm) thickness
• Wire Gauge Compatibility: Acceptable range for conductor accommodation
• Power Application Classification: Suitable for power distribution circuits
• Compliance Standards: RoHS3 compliance and REACH unaffected status

The substitute part 0002091139 operates within these parameter boundaries, with wire gauge specification of 18-22 AWG providing overlap with the original 22-24 AWG specification at the 22 AWG intersection point.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0002091119 is an active product substitute for the obsolete 0002091139. Both components maintain identical contact finish specifications, termination methods, and compliance certifications. The substitute part accommodates wire gauges from 18-22 AWG, with 22 AWG representing the upper limit of compatibility with the original specification range.

Selection of the 0002091119 is supported by its active product status, ensuring continued availability and supply chain reliability. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the 0002091119 directly replace the 0002091139 in all applications?

A: The 0002091119 is compatible for applications using 22 AWG wire, which falls within both the original 22-24 AWG and substitute 18-22 AWG specifications. Applications requiring 23-24 AWG wire may require evaluation of contact retention and crimping force characteristics.

Q: What is the significance of the wire gauge overlap?

A: The 22 AWG wire gauge represents the intersection point between the original specification (22-24 AWG) and the substitute specification (18-22 AWG). This overlap ensures electrical and mechanical compatibility at this conductor size.

Q: Are the contact finish specifications identical?

A: Both parts feature tin plating at 20.0µin (0.51µm) thickness, ensuring equivalent electrical conductivity and corrosion resistance characteristics.

Q: Why is the original part listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Molex. The active substitute part 0002091119 provides continued access to equivalent socket contact functionality.

Q: Do both parts meet the same regulatory standards?

A: Both the 0002091139 and 0002091119 are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory requirements for industrial and commercial applications.
