Molex 0387007516 Equivalent & Substitute Parts

Part Overview

The Molex 0387007516 is a 16-circuit barrier block connector with 0.325" (8.26mm) pitch, designed for through-hole mounting applications requiring screw termination. This component is classified as Active product status with full ROHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the primary part becomes unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0387007516 is determined by strict alignment of the following critical parameters:

• Terminal block type: Barrier Block
• Number of circuits: 16
• Pitch specification: 0.325" (8.26mm)
• Number of rows: 1
• Wire gauge compatibility: 14-22 AWG
• Voltage rating: 300V minimum
• Bottom termination: PC Pin
• Barrier configuration: 2 Wall (Dual)
• Mounting method: Through Hole
• RoHS compliance: ROHS3 Compliant

The Curtis Industries 325111-16-0 meets these core substitution criteria. Variations in current rating (15A vs. 20A), operating temperature maximum (105°C vs. 130°C), insulation material, and screw finish do not preclude substitution when the application electrical requirements fall within the substitute part's ratings.

Parameter Comparison

Engineering Selection Recommendations

The Curtis Industries 325111-16-0 is a qualified substitute for the Molex 0387007516 in applications where the circuit current requirement does not exceed 15A. Both components maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The substitute part operates within a maximum temperature of 105°C, which is suitable for applications not requiring the extended upper temperature range of the original part (130°C). The polypropylene insulation material of the substitute meets UL94 V-0 flammability classification, providing equivalent safety performance in standard industrial environments.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 325111-16-0 replace the Molex 0387007516 in all applications?

A: The Curtis Industries part is a direct substitute when circuit current requirements remain at or below 15A and operating temperatures do not exceed 105°C. Applications requiring the full 20A current capacity or extended temperature range to 130°C require the original Molex part.

Q: What is the significance of the captive plate on the Molex screw termination?

A: The captive plate on the Molex 0387007516 provides additional mechanical retention of the screw during assembly and maintenance. The Curtis Industries substitute uses standard screws without this feature. Both configurations provide equivalent electrical connection when properly torqued.

Q: Are the insulation materials interchangeable?

A: Thermoplastic and polypropylene (PP) are both suitable for standard industrial barrier block applications. The polypropylene material in the Curtis Industries part includes UL94 V-0 flammability rating. Material selection should be verified against specific application chemical exposure or thermal cycling requirements.

Q: Do both parts have identical pitch and circuit spacing?

A: Yes. Both the Molex 0387007516 and Curtis Industries 325111-16-0 maintain 0.325" (8.26mm) pitch with 16 circuits in a single row configuration, ensuring mechanical and electrical compatibility on PCB layouts designed for either part.

Q: What is the difference in wire entry capacity?

A: Both parts accommodate 16 wire entries with 14-22 AWG wire gauge specification. The number of wire entries matches the circuit count, providing one entry per circuit.
