• Voltage rating: 300V minimum
• Wire gauge compatibility: 14-22 AWG
• Top termination method: Screws
• Bottom termination: PC Pin
• Barrier configuration: 2 Wall (Dual)
• Mounting method: Through Hole
• Operating temperature range: -40°C ~ 100°C
• Insulation material: Thermoplastic
• Flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant

The substitute part Molex 0387206314 meets all these criteria and is classified as an active product, providing design continuity with improved component availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0387206314 is the qualified substitute for the obsolete Molex 0387290834. Both components maintain identical electrical and mechanical specifications across all critical parameters, including circuit count, pitch, current and voltage ratings, wire gauge compatibility, and termination methods.

The 0387206314 carries 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 and commercial applications.

The primary distinction is that the 0387206314 includes screws as part of the standard package, whereas the 0387290834 specifies screws as not included. This represents an enhancement in component completeness rather than a functional difference.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0387206314 be used as a direct replacement for the 0387290834?

A: Yes. Both components share identical electrical ratings (15A, 300V), mechanical configuration (14 circuits, 0.375" pitch), termination methods (screw top, PC pin bottom), and environmental specifications (-40°C ~ 100°C operating range). The 0387206314 is an active product, making it the appropriate choice for new designs and production.

Q: What is the difference between these two part numbers?

A: The primary difference is product status and packaging completeness. The 0387290834 is obsolete with screws listed as not included. The 0387206314 is an active product with screws included in the standard package. All functional and electrical parameters are equivalent.

Q: Are there any compatibility concerns when substituting the 0387206314 for the 0387290834?

A: No compatibility concerns exist. Both components feature identical barrier block construction, dual-wall barrier type, thermoplastic insulation, and through-hole mounting. PCB footprints and circuit spacing are identical due to matching pitch and circuit count specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 0387290834 and 0387206314 are ROHS3 compliant and carry UL94 V-0 flammability certification. They meet identical regulatory requirements for industrial applications.

Q: What is the significance of the "2 Wall (Dual)" barrier type?

A: The dual-wall barrier configuration provides electrical isolation between adjacent circuits, preventing cross-talk and ensuring signal integrity in multi-circuit applications. Both parts incorporate this same barrier design.
