Weidmüller 1940450000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1940450000 is a 15-position terminal block plug with female sockets, 0.150" (3.81mm) pitch, designed for 270° free-hanging in-line applications. This component belongs to the Omnimate BC series and features screw-clamping termination with copper alloy contacts rated for 17.5A (IEC) and 10A (UL) operation.

The 1940450000 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for maintenance, repair, and new installations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1940450000 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (IEC: 17.5A, UL: 10A), voltage rating (IEC: 320V, UL: 300V), and wire gauge range (16-28 AWG / 0.2-1.5mm²)
• Mechanical Compatibility: 15-position configuration, 0.150" (3.81mm) pitch, 270° wire entry orientation, screw-clamping termination, and free-hanging mounting
• Environmental & Regulatory Compliance: Operating temperature range (-50°C to 120°C), UL94 V-0 flammability rating, IP20 ingress protection, RoHS compliance, and REACH unaffected status

The substitute part 1940320000 maintains full equivalence across all critical electrical, mechanical, and regulatory parameters. The only difference is housing color (orange versus black) and product status (active versus obsolete), neither of which affects functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1940320000 is the direct functional equivalent for the obsolete 1940450000. Both components are manufactured by Weidmüller within the Omnimate BC series and maintain identical electrical ratings, mechanical specifications, and regulatory compliance certifications.

The 1940320000 carries active product status, ensuring ongoing availability and supply chain continuity. Both parts are RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements. The housing color difference (orange versus black) is a cosmetic distinction that does not affect electrical performance, mechanical fit, or system functionality.

For applications where the original 1940450000 is specified, the 1940320000 provides complete interchangeability without design modification or system reconfiguration.

Frequently Asked Questions (FAQ)

Q: Can the 1940320000 replace the 1940450000 in existing installations?

A: Yes. Both components are electrically and mechanically equivalent. They share identical current ratings (17.5A IEC / 10A UL), voltage ratings (320V IEC / 300V UL), wire gauge compatibility (16-28 AWG), pitch (0.150"), position count (15), termination method (screw-clamping), and mounting configuration (270° free-hanging in-line). The housing color difference does not affect functional interchangeability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the 1940450000 and 1940320000 carry identical compliance certifications: UL94 V-0 flammability rating, IP20 ingress protection, RoHS compliance, and REACH unaffected status. Both operate across the same temperature range (-50°C to 120°C) and use identical contact materials (copper alloy with tin mating finish).

Q: What is the significance of the product status difference?

A: The 1940450000 is classified as obsolete, indicating it is no longer in active production. The 1940320000 maintains active product status, ensuring continued manufacturing, availability, and supply chain support. For new designs or long-term applications, the 1940320000 is the recommended selection.

Q: Does the packaging difference affect compatibility?

A: No. The 1940450000 is supplied in standard packaging, while the 1940320000 is supplied in bulk packaging. Packaging format does not affect the component's electrical performance, mechanical specifications, or functional interchangeability.

Q: Are the screw torque specifications identical?

A: Yes. Both components use M2 screws with identical torque specifications of 0.2-0.25 Nm (1.7-2.2 Lb-In). Wire strip length is also identical at 7mm for both parts.
