Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0387290439 is determined by strict equivalence across the following critical parameters:

• Terminal block type (Barrier Block)
• Number of circuits (7)
• Pitch spacing (0.375" / 9.53mm)
• Current rating (15A minimum)
• Voltage rating (300V minimum)
• Wire gauge compatibility (14-22 AWG)
• Mounting configuration (Chassis/Panel)
• Barrier design (2 Wall / Dual)
• Flange feature presence

The substitute part Molex 0387200207 meets all these criteria and is classified as active product status, providing long-term availability and supply chain continuity.
