Key Parameters

Substitute Part Grouping Explanation

The Stewart Connector SS-39200-006 qualifies as a direct substitute based on the following alignment of critical parameters:

• Connector Type & Position Count: Both are 8p8c (RJ45, Ethernet) plugs with identical contact configuration
• Shielding & Termination: Both feature shielded construction with IDC termination
• Cable Compatibility: Both accept round cable with solid or stranded wires
• Electrical Ratings: Both maintain 1.5 A current rating and exceed the original 125V requirement (150V rating)
• Contact Finish & Material: Both use gold-plated contacts with equivalent surface finish thickness (50.0µin)
• Housing Material: Both utilize Polycarbonate (PC) construction
• Compliance: Both are ROHS3 compliant and REACH unaffected

The primary difference is the Cat6 rating of the substitute versus Cat5 of the original part, which represents an enhancement in bandwidth capability while maintaining backward compatibility with Cat5 applications.

Parameter Comparison

Engineering Selection Recommendations

The Stewart Connector SS-39200-006 is suitable for applications currently using the Molex 0950435892. The substitute maintains all critical electrical and mechanical parameters required for RJ45 Ethernet connectivity. The Cat6 rating provides enhanced performance margin over the original Cat5 specification while preserving full backward compatibility. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The active product status of the Stewart Connector ensures continued availability and supply chain stability compared to the obsolete Molex part.

Frequently Asked Questions (FAQ)

Q: Can the Stewart Connector SS-39200-006 directly replace the Molex 0950435892 in existing designs?

A: Yes. Both connectors share identical 8p8c (RJ45) contact configuration, shielded construction, IDC termination, and equivalent electrical ratings. The Cat6 rating of the substitute exceeds the Cat5 requirement of the original part.

Q: What is the significance of the Cat6 versus Cat5 rating difference?

A: Cat6 represents a higher bandwidth category standard suitable for Gigabit Ethernet applications. Cat6 connectors are fully compatible with Cat5 installations and applications, providing enhanced performance margin.

Q: Are there dimensional compatibility concerns between these parts?

A: The Stewart Connector is 0.098" (2.49mm) longer than the Molex part. Verify adequate clearance in the application's connector cavity or strain relief area before substitution.

Q: Do both parts support the same wire gauges and termination methods?

A: Both use IDC termination with round cable. The Stewart Connector explicitly supports solid or stranded wires, while the Molex specification does not detail wire type. Verify wire gauge compatibility with your specific cable assembly.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution in regulated applications.
