Weidmüller 1946000000 Terminal Block Plug Equivalent & Substitute Parts

Part Overview

The Weidmüller 1946000000 is a 4-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, designed for 225° free-hanging in-line applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The Omnimate BL series plug accommodates wire gauges from 12-30 AWG (0.2-4mm²) with screw-clamping termination and operates across -50°C to 100°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1946000000 is determined by strict equivalence across the following critical parameters:

• Number of positions: 4
• Pitch spacing: 0.200" (5.08mm)
• Plug wire entry angle: 225°
• Termination method: Screw-clamping yoke
• Mounting configuration: Free hanging (in-line)
• Electrical ratings: IEC 17.5A/400V and UL 15A/300V
• Wire gauge compatibility: 12-30 AWG (0.2-4mm²)
• Contact material: Copper alloy
• Housing material: Polybutylene terephthalate (PBT)
• Flammability rating: UL94 V-0
• Operating temperature range: -50°C to 100°C

The substitute part 1945770000 maintains identical electrical, mechanical, and material specifications. The primary difference is packaging format (bulk versus original packaging) and housing color (orange versus black), neither of which affects functional compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1945770000 is a direct functional equivalent to the obsolete 1946000000. Both components are manufactured by Weidmüller within the Omnimate BL series and maintain identical electrical, mechanical, and material specifications across all critical parameters.

The 1945770000 holds active product status, ensuring ongoing availability and manufacturer support. Both parts carry RoHS compliance and REACH unaffected designation, meeting current regulatory requirements. The UL94 V-0 flammability rating is maintained across both variants.

The only non-functional differences are housing color (orange versus black) and packaging format (bulk versus original). These differences do not impact electrical performance, mechanical fit, or thermal characteristics. Selection between these parts should be based on application-specific requirements regarding color coding and packaging logistics.

Frequently Asked Questions (FAQ)

Q: Can the 1945770000 directly replace the 1946000000 in existing applications?

A: Yes. The 1945770000 maintains identical electrical ratings (IEC 17.5A/400V, UL 15A/300V), mechanical configuration (4-position, 5.08mm pitch, 225° wire entry), termination method (screw-clamping yoke), and material specifications (copper alloy contacts, PBT housing, UL94 V-0). Functional compatibility is complete.

Q: Are there differences in wire gauge compatibility?

A: No. Both parts accommodate 12-30 AWG (0.2-4mm²) wire gauges with identical screw torque specifications (0.4-0.5 Nm).

Q: Does the color difference (black versus orange) affect performance?

A: No. Housing color is a cosmetic distinction only and does not affect electrical performance, thermal characteristics, or mechanical function.

Q: What is the significance of the product status change from obsolete to active?

A: The 1945770000 is actively manufactured and supported by Weidmüller, ensuring continued availability and technical support. The 1946000000 is obsolete and no longer produced.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 1946000000 and 1945770000 are RoHS compliant and REACH unaffected.

Q: Does packaging format affect compatibility?

A: No. Packaging format (bulk versus original) is a logistics consideration only and does not affect the component's electrical or mechanical properties.
