Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0387244103 is determined by the following critical parameters:

• Circuit Configuration: 3 circuits with 0.375" (9.53mm) pitch
• Termination Method: Screw termination (top) and PC pin (bottom)
• Barrier Type: 3 Wall (Tri) barrier configuration
• Mounting: Through-hole PCB mounting
• Electrical Performance: Minimum 300V voltage rating and compatible current handling
• Wire Compatibility: Support for 14-22 AWG wire gauge range
• Environmental: Operating temperature range and moisture sensitivity level

The substitute part TE Connectivity AMP Connectors 6PCV-03-006 meets these core substitution criteria through identical circuit count, pitch spacing, barrier configuration, and mounting methodology. Electrical ratings exceed or match the original specification, ensuring functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 6PCV-03-006 is a qualified substitute for the Molex 0387244103 based on the following engineering criteria:

Electrical Equivalence: Both components maintain 300V voltage rating and 3-circuit configuration. The substitute part provides 25A current rating, which exceeds the original 15A specification, ensuring adequate performance margin in applications operating at or below the original current requirement.

Mechanical Compatibility: Identical 0.375" (9.53mm) pitch, 3-wall barrier configuration, and through-hole mounting ensure direct PCB layout compatibility without redesign.

Compliance Status: Both components are RoHS compliant and carry EAR99 export classification. The substitute part includes UL94 V-0 flammability rating, providing additional material certification documentation.

Wire Gauge Range: The substitute accepts 12-22 AWG wire gauge, which encompasses the original 14-22 AWG specification, allowing broader wire selection flexibility.

Environmental Performance: Both components operate across -40°C to 100°C range with MSL 1 rating, suitable for standard industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6PCV-03-006 be used as a direct replacement for the Molex 0387244103 on existing PCBs?

A: Yes. Both components share identical pitch (0.375"), circuit count (3), barrier configuration (3-wall), and through-hole mounting footprint. No PCB layout modification is required.

Q: What is the significance of the higher 25A current rating on the substitute part?

A: The substitute part's 25A rating provides additional current-carrying capacity compared to the original 15A specification. Applications designed for 15A operation remain fully compatible and benefit from increased safety margin.

Q: Are there differences in wire gauge compatibility?

A: The substitute part accepts 12-22 AWG wire gauge versus the original 14-22 AWG range. This allows use of larger gauge conductors (12 AWG) if required by circuit design, while maintaining compatibility with the original 14-22 AWG specification.

Q: What is the difference between PBT and Thermoplastic insulation materials?

A: Both materials provide electrical insulation suitable for 300V applications. PBT (Polybutylene Terephthalate) is a specific engineering thermoplastic, while the substitute uses a general thermoplastic designation. Both meet the electrical and environmental requirements for this connector category.

Q: Are both components RoHS compliant?

A: Yes. The Molex 0387244103 is RoHS3 compliant, and the TE Connectivity 6PCV-03-006 is RoHS compliant. Both meet lead-free and hazardous substance restrictions for regulated markets.

Q: What does the UL94 V-0 rating on the substitute part indicate?

A: UL94 V-0 is a flammability classification indicating the material self-extinguishes within specified time limits when exposed to flame. This certification is provided for the substitute part and represents an additional material qualification.
