Weidmüller 1972020000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1972020000 is a 5-position terminal block plug with male pins, 0.150" (3.81mm) pitch, designed for 180° free-hanging in-line applications. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. The Omnimate SC series plug accommodates wire gauges from 16-28 AWG (0.2-1.5mm²) with screw-clamping termination and meets IEC and UL electrical ratings for industrial control and automation applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Weidmüller 1972020000 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Identical IEC and UL current and voltage ratings (17.5A/320V IEC; 10A/300V UL)
• Physical Compatibility: Matching 5-position configuration, 0.150" (3.81mm) pitch, and 180° free-hanging in-line orientation
• Termination Compatibility: Screw-clamping yoke termination style with identical wire gauge acceptance (16-28 AWG / 0.2-1.5mm²)
• Regulatory Compliance: RoHS compliance and UL94 V-0 flammability rating maintained
• Series Continuity: Omnimate SC series designation

The substitute part Weidmüller 2444100000 meets all these criteria while maintaining active product status, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 2444100000 is the direct functional equivalent for the obsolete 1972020000. Both components are manufactured by Weidmüller within the Omnimate SC series and maintain identical electrical ratings, physical dimensions, and termination characteristics. The substitute part carries active product status, ensuring availability for new procurement and replacement applications.

Both parts satisfy RoHS compliance requirements and maintain UL94 V-0 flammability certification. The screw-clamping termination style and wire gauge acceptance range are identical, permitting direct substitution in existing circuit designs without modification to wiring harnesses or connector interfaces.

Frequently Asked Questions (FAQ)

Q: Can the 2444100000 be used as a direct replacement for the 1972020000?

A: Yes. Both parts share identical electrical ratings (17.5A/320V IEC; 10A/300V UL), physical configuration (5-position, 0.150" pitch), termination method (screw-clamping yoke), and wire gauge acceptance (16-28 AWG). The substitute maintains the same mounting orientation (180° free-hanging in-line) and contact material specifications.

Q: What is the primary difference between these two parts?

A: The 1972020000 is classified as obsolete, while the 2444100000 maintains active product status. The substitute part is available for ongoing procurement. Housing material specifications differ slightly (PA vs. PA66), but both meet identical electrical and mechanical performance requirements.

Q: Are there any packaging or inventory considerations?

A: The 1972020000 is available in limited quantities (771 pcs). The 2444100000 is supplied in bulk packaging with higher inventory availability (957 pcs), making it the preferred choice for new designs and production orders.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both components are RoHS compliant, carry UL94 V-0 flammability ratings, and share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: Is the screw torque specification identical?

A: The 1972020000 specifies screw torque of 0.2-0.25 Nm (1.7-2.2 Lb-In). The 2444100000 does not provide a torque specification in the available data. For critical applications, reference the 1972020000 torque value as the established standard for the Omnimate SC series.
