Substitute Part Grouping Explanation

Substitution of the Molex 0387217606 is determined by strict equivalence across the following critical parameters:

• Terminal block type (Barrier Block)
• Number of circuits (6)
• Pitch specification (0.375" / 9.53mm)
• Current and voltage ratings (15A / 300V)
• Wire gauge compatibility (14-22 AWG)
• Termination methods (Screw top, Quick Connect bottom)
• Barrier configuration (2 Wall / Dual)
• Operating temperature range (-40°C ~ 100°C)
• Regulatory compliance (UL94 V-0, ROHS3)

The substitute part Molex 0387216706 meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete 0387217606.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0387216706 is the recommended substitute for the obsolete 0387217606. Both components are manufactured by Molex and share identical electrical and mechanical specifications across all critical parameters. The substitute part maintains full compliance with ROHS3 and UL94 V-0 flammability requirements.

The primary distinction between the two parts is product status: the 0387217606 is obsolete, while the 0387216706 is active and currently in production. The 0387216706 is available in bulk packaging with significantly higher inventory levels (3528 units in stock versus 794 units for the obsolete part), ensuring supply chain continuity for ongoing applications.

Material composition differs slightly between the two parts: the main part uses thermoplastic insulation with zinc chromate finish on terminal screws, while the substitute uses polybutylene terephthalate (PBT) glass-filled insulation with zinc clear chromate finish. These material variations do not affect functional equivalence within the specified electrical and thermal operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0387216706 be used as a direct replacement for the 0387217606 in existing designs?

A: Yes. The 0387216706 meets all electrical, mechanical, and thermal specifications of the 0387217606. Both components share identical circuit count, pitch, current/voltage ratings, wire gauge compatibility, and termination methods. The substitute is suitable for direct substitution in applications where the original part is specified.

Q: What is the difference in insulation material between these two parts?

A: The 0387217606 uses thermoplastic insulation, while the 0387216706 uses polybutylene terephthalate (PBT) with glass reinforcement. Both materials meet UL94 V-0 flammability requirements and operate across the same temperature range (-40°C ~ 100°C). The PBT glass-filled material in the substitute provides enhanced mechanical and thermal stability.

Q: Are there packaging differences between the main part and substitute?

A: The 0387217606 is supplied in standard packaging, while the 0387216706 is available in bulk packaging. This distinction affects order quantities and logistics but does not impact component functionality or performance.

Q: Does the terminal screw finish difference affect compatibility?

A: No. Both zinc chromate (main part) and zinc clear chromate (substitute) finishes provide equivalent corrosion resistance and electrical conductivity for this application. The finish difference does not affect functional performance or compliance with specified electrical parameters.

Q: Is the 0387216706 REACH compliant?

A: The 0387216706 is REACH Affected. Compliance status should be verified against specific project requirements and regional regulations if REACH compliance is a design criterion.
