Molex 0395372502 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Molex 0395372502 is a 2-position terminal block plug featuring female sockets with 270° free-hanging (in-line) wire entry configuration. This component belongs to the Eurostyle ESE 39537 series and is designed for applications requiring screw-rising cage clamp termination with 5.08mm pitch spacing. The part is currently active in production with 709 units in stock. Alternative models may be required when application specifications demand different wire entry angles, voltage ratings, or mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0395372502 is determined by the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 2-position configuration. The Molex part specifies 5.08mm pitch; substitute parts must accommodate the same wire spacing requirements.
• Connector Type: Both must be plug-type connectors with female sockets for mating compatibility.
• Termination Method: Screw-based termination is required for both parts to ensure equivalent installation procedures.
• Mounting Configuration: Free-hanging (in-line) mounting must be preserved.
• Wire Entry Angle: The 270° wire entry angle is application-specific. Substitutes with different angles (such as 90°) represent functional alternatives for different installation geometries.
• Electrical Ratings: Current and voltage ratings must meet or exceed application requirements. The Molex part is rated 10A at 300V (UL). Substitutes with higher ratings (such as 20A at 600V) are electrically compatible.
• Wire Gauge Compatibility: The 12-26 AWG range must be supported by substitute parts.
• Compliance & Certifications: RoHS and UL94 V-0 flammability ratings ensure regulatory alignment.

The Phoenix Contact 3045402 qualifies as a substitute based on matching position count, connector type, termination method, mounting style, wire gauge range, and compliance certifications, despite differences in wire entry angle and electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

Molex 0395372502 is the primary choice for applications requiring 270° wire entry configuration with UL certification at 300V/10A ratings. This part maintains active production status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Phoenix Contact 3045402 serves as a functional substitute when application geometry requires 90° wire entry orientation. This part provides higher electrical ratings (600V/20A UL, 500V/24A IEC), making it suitable for applications with elevated voltage or current demands. Both parts maintain identical position counts, wire gauge compatibility, and UL94 V-0 flammability certification. The Phoenix Contact part is RoHS compliant and carries MSL 1 rating, matching the Molex part's environmental specifications.

Selection between these parts depends on physical installation constraints (wire entry angle) and electrical requirement thresholds rather than functional capability differences.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3045402 directly replace the Molex 0395372502 in existing installations?

A: Direct mechanical replacement is possible only if the application accommodates 90° wire entry instead of 270°. Both parts share identical 2-position configuration, 5.08mm pitch spacing, and screw termination methodology. Electrical compatibility is confirmed, as the Phoenix Contact part exceeds the Molex part's current and voltage ratings.

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

A: The primary differences are wire entry angle (270° vs. 90°), electrical ratings (Molex: 10A/300V UL; Phoenix Contact: 20A/600V UL), and housing color (black vs. gray). Both maintain equivalent position counts, termination styles, mounting configurations, and compliance certifications.

Q: Are both parts suitable for the same wire gauge applications?

A: Yes. Both parts support 12-26 AWG wire gauge range, ensuring compatibility with identical conductor specifications.

Q: What compliance certifications do these parts carry?

A: Both parts are UL94 V-0 rated for flammability and carry RoHS compliance. The Molex part is ROHS3 compliant, while the Phoenix Contact part is RoHS compliant. Both are classified as EAR99 for export control purposes.

Q: How do the screw torque specifications compare?

A: The Molex part specifies 0.34 Nm (3.0 Lb-In) torque. The Phoenix Contact part specifies 0.5-0.6 Nm (4.4-5.3 Lb-In) torque. These differences reflect design variations in screw engagement mechanisms and should be observed during installation.
