Substitute Part Grouping Explanation

Substitution of the Molex 0387106305 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: 5 circuits with 0.375" (9.53mm) pitch and single-row arrangement
• Termination Method: Screw-based top termination with PC pin bottom termination
• Barrier Construction: Dual-wall (2 Wall) barrier type for circuit isolation
• Mounting Interface: Through-hole mounting compatibility
• Electrical Performance: Minimum 15A current rating at 300V voltage rating
• Wire Compatibility: Support for 14-22 AWG wire gauge range
• Environmental Compliance: RoHS compliance and MSL 1 rating

The TE Connectivity AMP Connectors NC6-P107-05 meets all substitution criteria while providing enhanced electrical performance (20A current rating) and extended operating temperature range (-40°C ~ 105°C). Both components share identical mechanical footprint, pitch spacing, and termination architecture, enabling direct substitution in PCB-mounted applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity NC6-P107-05 is a qualified substitute for the Molex 0387106305 based on functional equivalence across all critical mechanical and electrical parameters. Both components are active products with current manufacturing status and full RoHS compliance.

Selection between these parts should be based on:

• Electrical Margin: The TE part provides 33% higher current rating (20A vs. 15A), offering additional design margin for applications operating near maximum current specifications.
• Temperature Performance: The TE part extends the upper operating temperature limit to 105°C, suitable for applications in elevated thermal environments.
• Wire Gauge Flexibility: The TE part accommodates 12 AWG wire, enabling use in applications requiring heavier gauge conductors.
• Material Specification: The Molex part uses glass-filled PBT insulation, while the TE part uses polyamide nylon with UL94 V-0 flammability certification. Material selection should align with specific application requirements for chemical resistance and flame performance.
• Inventory Availability: The TE part shows higher stock levels (3632 pcs vs. 722 pcs), supporting procurement timelines.

Both parts maintain identical mechanical footprint and pitch spacing, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity NC6-P107-05 be used as a direct replacement for the Molex 0387106305?

A: Yes. Both components share identical circuit count (5), pitch spacing (0.375"), termination method (screw top, PC pin bottom), barrier construction (dual-wall), and mounting interface (through-hole). The TE part meets or exceeds all electrical specifications of the Molex part.

Q: What are the key differences between these two parts?

A: The TE part provides higher current rating (20A vs. 15A), extended operating temperature range (-40°C to 105°C vs. -40°C to 100°C), wider wire gauge support (12-22 AWG vs. 14-22 AWG), and includes UL94 V-0 flammability certification. Insulation material differs: Molex uses glass-filled PBT; TE uses polyamide nylon.

Q: Are there any compatibility concerns with PCB mounting?

A: No. Both parts use identical through-hole PC pin termination and 0.375" pitch spacing. No PCB layout modifications are required for substitution.

Q: Which part should be selected for high-temperature applications?

A: The TE Connectivity NC6-P107-05 is rated to 105°C, providing 5°C additional margin compared to the Molex part rated to 100°C.

Q: Does the insulation material difference affect substitution suitability?

A: Material selection depends on application requirements. Glass-filled PBT (Molex) offers superior chemical resistance in certain environments. Polyamide nylon (TE) provides UL94 V-0 flammability certification. Verify material compatibility with your specific application environment.

Q: Can the TE part handle heavier gauge wires than the Molex part?

A: Yes. The TE part supports 12-22 AWG wire gauge, while the Molex part supports 14-22 AWG. Applications requiring 12 AWG conductors must use the TE part.

Q: Are both parts RoHS compliant?

A: Yes. The Molex part is RoHS3 compliant. The TE part is RoHS compliant. Both meet regulatory requirements for lead-free manufacturing.
