Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0387290366 is determined by the following critical parameters:

• Terminal block type (Barrier Block)
• Number of circuits (6)
• Pitch specification (0.375" / 9.53mm)
• Current rating (15A minimum)
• Voltage rating (300V minimum)
• Wire gauge compatibility (14-22 AWG)
• Top termination method (Screws)
• Barrier configuration (2 Wall / Dual)
• Operating temperature range (-40°C ~ 100°C)
• Flammability rating (UL94 V-0)
• RoHS compliance status

The Molex 0387200206 meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0387200206 is the qualified substitute for the obsolete 0387290366. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The 0387200206 carries active product status, ensuring ongoing availability and supply chain continuity.

The substitute part includes a flange feature and maintains ROHS3 compliance. The terminal screw finish differs (Zinc, Clear Chromate versus Zinc, Chromate), which does not affect functional compatibility within the specified operating parameters.

Selection of the 0387200206 is appropriate for new designs and replacement applications requiring the 6-circuit, 0.375" pitch barrier block connector configuration.

Frequently Asked Questions (FAQ)

Q: Can the 0387200206 directly replace the 0387290366 in existing applications?

A: Yes. Both parts share identical electrical ratings (15A, 300V), mechanical pitch (0.375"), circuit count (6), wire gauge compatibility (14-22 AWG), and operating temperature range (-40°C ~ 100°C). The flange feature on the substitute part does not affect screw-terminal functionality.

Q: What is the difference between the two parts?

A: The primary differences are product status (0387290366 is obsolete; 0387200206 is active) and packaging (bulk for the substitute). The 0387200206 includes a flange feature and uses Zinc, Clear Chromate terminal screw finish compared to Zinc, Chromate on the original part. These differences do not impact electrical or mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0387290366 and 0387200206 are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What mounting configurations are supported?

A: Both parts support chassis and panel mounting configurations with screw-based termination.

Q: Is the flange feature on the 0387200206 a compatibility concern?

A: No. The flange feature on the 0387200206 provides additional mounting stability and does not prevent substitution in applications designed for the 0387290366.
