Molex 0395373824 Terminal Block Plug – Equivalent & Substitute Parts

Part Overview

The Molex 0395373824 is a 24-position terminal block plug with female sockets, 5.08mm pitch, designed for free-hanging in-line applications. It features screw-rising cage clamp termination, gold-plated contacts, and operates across -40°C to 105°C. The component is Active status and RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed specifications for this product category, enabling direct replacement in compatible applications.

Key Parameters

Substitute Part Grouping Explanation

The Weidmüller 1949010000 is identified as a substitute based on the following alignment of critical parameters:

Matching Parameters:

• 24-position terminal block plug configuration
• 5.08mm (0.200") pitch spacing
• Female socket type
• Free-hanging in-line mounting
• Screw-based termination (cage clamp variant)
• UL voltage rating of 300 V
• UL94 V-0 flammability rating
• Active product status
• RoHS compliance

Allowable Variations: Substitution is valid where the following parameters differ within acceptable engineering tolerances for terminal block applications:

• Wire entry angle (90° vs. 270°)
• Termination mechanism variant (rising cage clamp vs. clamping yoke)
• Current rating (10 A UL vs. 20 A UL)
• Wire gauge range (12-26 AWG vs. 12-30 AWG)
• Operating temperature range (-40°C to 105°C vs. -50°C to 100°C)
• Contact finish (gold vs. tin)
• Housing material (PA66 vs. PBT)
• Color (black vs. orange)

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0395373824 and Weidmüller 1949010000 maintain Active product status and meet UL94 V-0 flammability requirements. Both are RoHS compliant, supporting regulatory requirements for new designs and production environments.

The Weidmüller 1949010000 offers higher current capacity (20 A UL vs. 10 A UL) and extended wire gauge compatibility (12-30 AWG vs. 12-26 AWG), providing broader application flexibility. The wider operating temperature floor (-50°C vs. -40°C) supports extended cold-environment deployment.

Selection between these parts depends on specific application requirements: wire entry angle orientation (90° vs. 270°), termination mechanism preference (rising cage clamp vs. clamping yoke), and contact finish specification (gold vs. tin). Both components satisfy the core electrical and mechanical requirements for 24-position, 5.08mm pitch terminal block plug applications.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1949010000 directly replace the Molex 0395373824?

A: Direct replacement is possible where the application accommodates the 270° wire entry angle (versus 90°) and the clamping yoke termination mechanism. Both components share identical pitch spacing, position count, and voltage rating. Verify mechanical fit within the enclosure or connector housing before substitution.

Q: What is the significance of the different wire entry angles?

A: The 90° entry on the Molex part directs wires perpendicular to the plug face, while the 270° entry on the Weidmüller part directs wires at an alternate angle. Physical space constraints and cable routing requirements determine which orientation is compatible with your assembly.

Q: Does the higher current rating of the Weidmüller part affect compatibility?

A: The Weidmüller 1949010000 is rated for 20 A UL, compared to 10 A UL for the Molex part. This higher rating does not prevent substitution in lower-current applications; it indicates the Weidmüller part can handle greater current loads. Verify that your application's actual current draw does not exceed the Molex part's 10 A limit if using the original component.

Q: Are there differences in contact finish that affect electrical performance?

A: The Molex part features gold-plated contacts; the Weidmüller part uses tin plating. Both finishes provide adequate electrical conductivity and corrosion resistance for standard industrial applications. Contact finish selection depends on specific environmental conditions and contact resistance requirements in your circuit design.

Q: What packaging is available for both parts?

A: Both the Molex 0395373824 and Weidmüller 1949010000 are supplied in Bulk packaging, suitable for production assembly and integration into larger systems.
