• Pitch: 0.375" (9.53mm)
• Current rating: 20A
• Voltage rating: 300V
• Wire gauge compatibility: 12-22 AWG
• Top termination method: Screws with Captive Plate
• Bottom termination: PC Pin
• Barrier configuration: 2 Wall (Dual)
• Mounting method: Through Hole
• Operating temperature range: -40°C ~ 100°C
• Flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant

The substitute part Molex 0387107407 maintains functional and electrical equivalence across all critical parameters. Differences in insulation material and terminal screw finish do not affect electrical performance or mechanical compatibility within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0387107407 is the direct substitute for the obsolete Molex 0387108607. Both components maintain identical electrical and mechanical specifications across all critical parameters required for barrier block connector applications.

The 0387107407 is classified as Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial applications.

The insulation material difference (Thermoplastic versus Polybutylene Terephthalate) and terminal screw finish variation (Zinc, Chromate versus Zinc, Clear Chromate) do not impact electrical performance, current carrying capacity, voltage withstand capability, or mechanical fit within the specified operating temperature range of -40°C to 100°C.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0387107407 be used as a direct replacement for the 0387108607 in existing designs?
