Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for terminal block connectors is determined by compatibility across the following critical parameters:

• Manufacturer: Molex (primary manufacturer)
• Product Category: Terminal Blocks
• Connector Type: Barrier block configuration
• Electrical Ratings: Current and voltage capacity
• Physical Interface: Pitch, circuit count, and termination method
• Environmental Compliance: RoHS and REACH certification status
• Operational Range: Temperature specifications

The substitute part Molex 0387200203 qualifies as an equivalent option based on shared manufacturer origin, terminal block category classification, and compatible electrical and mechanical specifications within the Molex product ecosystem.

Parameter Comparison

Engineering Selection Recommendations
