Molex 0386300413 Equivalent & Substitute Parts

Part Overview

The Molex 0386300413 is a 13-circuit barrier block connector with 0.438" (11.12mm) pitch, rated for 25A at 600V. This terminal block is designed for chassis and panel mounting applications requiring dual-wall barrier separation and screw termination. The part is active in production and ROHS3 compliant. Substitute parts may be required due to inventory constraints, regional availability, or specific application requirements where electrical and mechanical parameters align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0386300413 is determined by the following critical parameters:

• Circuit Configuration: 13 circuits with matching pitch (0.438" / 11.12mm)
• Electrical Ratings: Voltage rating of 600V minimum; current rating of 20A or higher
• Termination Method: Screw-based top termination with closed bottom termination
• Barrier Configuration: Dual-wall (2 Wall) barrier type for electrical isolation
• Mounting Compatibility: Chassis and panel mounting capability
• Compliance: ROHS3 compliance required

The Curtis Industries 430000-13-0 meets these substitution criteria with equivalent circuit count, pitch, voltage rating, termination method, barrier type, and mounting configuration. Differences in current rating (20A vs. 25A) and wire gauge range (12-22 AWG vs. 12-24 AWG) represent operational constraints that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Curtis Industries 430000-13-0 is a qualified substitute for the Molex 0386300413 based on matching circuit configuration, pitch, voltage rating, termination method, barrier type, and mounting compatibility. Both parts maintain ROHS3 compliance and MSL Level 1 rating.

Selection between these parts should account for the following:

• Current Rating Differential: The Molex part is rated for 25A while the Curtis Industries part is rated for 20A. Applications requiring current levels between 20A and 25A must use the Molex part.
• Wire Gauge Range: The Molex part accommodates 12-24 AWG while the Curtis Industries part accommodates 12-22 AWG. Applications using 24 AWG wire require the Molex part.
• Insulation Material: Molex uses Polybutylene Terephthalate (PBT); Curtis Industries uses Polypropylene (PP). Both materials are suitable for the specified voltage and temperature ranges.
• Product Status: Both parts are active in production with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 430000-13-0 be used in place of the Molex 0386300413 in all applications?

A: The Curtis Industries part is suitable for applications operating at 20A or below and using wire gauges from 12-22 AWG. Applications requiring the full 25A rating or 24 AWG wire compatibility must use the Molex part.

Q: Are the physical dimensions and mounting footprints identical?

A: Both parts share the same 13-circuit configuration with 0.438" (11.12mm) pitch, single-row layout, and flange-based chassis/panel mounting. Physical compatibility is maintained for PCB and panel mounting applications.

Q: What is the difference in insulation material between these parts?

A: The Molex part uses Polybutylene Terephthalate (PBT) while the Curtis Industries part uses Polypropylene (PP). Both materials meet the 600V voltage rating and operating temperature requirements. Material selection may be driven by specific environmental or chemical resistance requirements in the application.

Q: Are both parts RoHS compliant?

A: Yes, both the Molex 0386300413 and Curtis Industries 430000-13-0 are ROHS3 compliant and suitable for applications with RoHS requirements.

Q: What is the moisture sensitivity level for these parts?

A: Both parts are rated MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
