Molex 0395232811 Terminal Block Plug – Equivalent & Substitute Parts

Part Overview

The Molex 0395232811 is an 11-position terminal block plug featuring female sockets with 0.197" (5.00mm) pitch spacing and 270° wire entry orientation. This component is part of the Eurostyle ESE 39523 series and is designed for screw-based termination in free-hanging (in-line) mounting configurations. The part maintains Active product status with 728 units currently in stock. Terminal block plugs of this specification are essential in industrial control systems, automation equipment, and modular power distribution applications where reliable electrical connections and mechanical interchangeability are required. Identifying equivalent substitute parts ensures design flexibility and supply chain continuity when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for terminal block plugs is determined by strict alignment of electrical and mechanical parameters. The Weidmüller 1948100000 is identified as a manufacturer-recommended substitute based on the following critical parameters:

Electrical Compatibility:

• Both parts support 11 positions with female socket configuration
• Both maintain UL94 V-0 flammability rating
• Both support 300 V UL voltage specification
• Both employ screw-based termination methods

Mechanical Compatibility:

• Both feature free-hanging (in-line) mounting orientation
• Both accommodate wire gauges within overlapping ranges (12-26 AWG for Molex; 12-30 AWG for Weidmüller)
• Both are designed for industrial terminal block applications

Differences Requiring Evaluation:

• Pitch spacing: Molex 0.197" (5.00mm) versus Weidmüller 0.200" (5.08mm) — minor variance
• Wire entry angle: Molex 270° versus Weidmüller 90° — different connector orientation
• Current rating: Molex 15 A (UL) versus Weidmüller 20 A (UL) — Weidmüller rated higher
• Operating temperature: Molex -40°C ~ 105°C versus Weidmüller -50°C ~ 100°C — overlapping ranges

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0395232811 and Weidmüller 1948100000 maintain Active product status with full compliance to RoHS standards and UL94 V-0 flammability requirements. Selection between these parts should be based on specific application requirements:

The Molex 0395232811 is the primary choice when 270° wire entry orientation is a design requirement and when operating temperatures approach 105°C. The part's ROHS3 compliance provides the highest environmental standard certification.

The Weidmüller 1948100000 is suitable as a substitute when higher current capacity (20 A versus 15 A) is beneficial, when 90° wire entry orientation accommodates the mechanical layout, and when extended low-temperature operation to -50°C is required. The Weidmüller part supports wire gauges up to 30 AWG, providing greater flexibility for smaller conductor applications.

Both parts are suitable for industrial control, automation, and power distribution applications. The pitch spacing difference (0.197" versus 0.200") is within standard manufacturing tolerances for terminal block applications and does not preclude mechanical interchangeability in most mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1948100000 directly replace the Molex 0395232811 in existing designs?

A: Direct replacement depends on two factors: wire entry orientation and pitch spacing tolerance. The Molex part features 270° entry while the Weidmüller part features 90° entry. If the connector orientation is fixed in your mechanical design, the 90° entry may not be compatible. The pitch spacing difference (5.00mm versus 5.08mm) is minor but may affect mating with existing receptacles designed for the Molex specification.

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

A: Both parts support 300 V UL voltage and UL94 V-0 flammability. The Weidmüller part is rated for 20 A (UL) compared to the Molex 15 A (UL), making it suitable for higher-current applications. The Weidmüller part also supports IEC ratings of 23 A at 400 V, providing additional international standard compliance.

Q: Are there temperature range considerations for substitution?

A: The Molex part operates from -40°C to 105°C, while the Weidmüller part operates from -50°C to 100°C. The Molex part supports higher maximum temperature, making it preferable for applications approaching 105°C. The Weidmüller part supports lower minimum temperature, suitable for cold-environment applications.

Q: What wire gauge compatibility should I verify?

A: The Molex part accommodates 12-26 AWG wire. The Weidmüller part accommodates 12-30 AWG wire, supporting smaller conductors. If your application uses wire gauges between 27-30 AWG, only the Weidmüller part is suitable.

Q: How do the termination methods differ?

A: The Molex part uses a Rising Cage Clamp termination method, while the Weidmüller part uses a Clamping Yoke (Tension Sleeve) method. Both are screw-based termination systems. The Molex part specifies 0.56 Nm (5.0 Lb-In) torque, while the Weidmüller part specifies 0.4-0.5 Nm (4.6-4.4 Lb-In) torque. Verify your assembly equipment can accommodate the appropriate torque specification.

Q: What compliance certifications should I verify for my application?

A: Both parts maintain UL94 V-0 flammability rating and Active product status. The Molex part is ROHS3 compliant, while the Weidmüller part is RoHS compliant. For applications requiring the highest environmental standard, the Molex ROHS3 certification is preferable. Both parts carry EAR99 ECCN classification.
