Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0039000342 is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the KK 2478 series to ensure mechanical and electrical compatibility within connector housings and assemblies.
• Contact Configuration: Non-gendered contact type must be maintained for proper mating characteristics.
• Termination Method: Crimp termination is required for consistent wire attachment and electrical performance.
• Wire Gauge Range: 18-24 AWG wire gauge compatibility ensures proper contact engagement and current-carrying capacity.
• Contact Finish: Tin finish maintains consistent electrical properties and corrosion resistance.
• Compliance Standards: RoHS3 compliance and REACH unaffected status must be preserved for regulatory adherence.

The substitute part Molex 0008500106 meets all these criteria and is classified as active product status, providing a viable alternative to the obsolete 0039000342.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0008500106 is the qualified substitute for the obsolete Molex 0039000342. Both components share identical electrical and mechanical specifications across all critical parameters: series designation, contact configuration, termination method, wire gauge range, and contact finish. Both maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and system updates.

The primary distinction is product status: 0008500106 is actively manufactured and stocked, with significantly higher inventory availability (252,053 pieces) compared to the obsolete 0039000342 (770 pieces). This availability differential makes 0008500106 the appropriate selection for ongoing procurement and system maintenance.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0008500106 be used as a direct replacement for the 0039000342?

A: Yes. Both components are identical in series, contact configuration, termination method, wire gauge range, and contact finish. They are mechanically and electrically interchangeable within KK 2478 connector assemblies.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The 0039000342 is obsolete with limited stock, while the 0008500106 is an active product with bulk packaging and substantial inventory availability. Contact finish thickness differs slightly (35.4µin versus 100.0µin), but both meet tin finish specifications.

Q: Are there any compliance or regulatory differences?

A: No. Both parts maintain identical RoHS3 compliance and REACH unaffected status. There are no regulatory barriers to substitution.

Q: What wire gauges are supported by these contacts?

A: Both the 0039000342 and 0008500106 support 18-24 AWG wire gauge range for crimp termination.

Q: Is the packaging difference significant for component selection?

A: The 0039000342 has unspecified packaging, while the 0008500106 is supplied in bulk packaging. For procurement purposes, bulk packaging typically offers better availability and cost efficiency for production environments.
