DS20-BU Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The DS20-BU is a 2-position feed-through terminal block connector manufactured by Eaton - Bussmann Electrical Division, part of the Magnum® DS series. This component is designed for screw termination of conductors in the 12-22 AWG range with a rated capacity of 24 A at 1000V (IEC) and 20 A at 600V (UL). The DS20-BU is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS20-BU is determined by the following critical parameters that must be maintained or exceeded:

• Electrical Performance: Current rating of 24 A (IEC) minimum and voltage rating of 1000 V (IEC) minimum
• Physical Configuration: 2-position, single-level feed-through terminal block with 5.1 mm terminal width
• Termination Method: Screw termination for conductor attachment
• Wire Gauge Compatibility: Acceptance of 12-22 AWG (0.5-2.5 mm²) conductors
• Safety Compliance: UL94 V-0 flammability rating

The Weidmüller 1412950000 (WDU 2.5 HV) meets these substitution criteria through equivalent electrical ratings, identical physical configuration, and compatible termination methodology. The substitute part maintains the required safety certifications and supports the specified wire gauge range.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1412950000 (WDU 2.5 HV) is a direct functional equivalent for the obsolete DS20-BU. Both components maintain identical electrical performance specifications (24 A at 1000 V IEC), physical configuration (2-position, 5.1 mm terminal width), and safety certifications (UL94 V-0). The substitute part is currently in active production status with confirmed inventory availability, addressing the obsolescence of the original component.

The Weidmüller substitute accepts a broader wire gauge range (12-30 AWG versus 12-22 AWG), which provides additional flexibility for conductor selection without compromising performance within the original specification envelope. Both components employ screw termination methodology and are suitable for identical application contexts.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1412950000 be used as a direct replacement for the DS20-BU in existing designs?

A: Yes. Both components share identical electrical ratings (24 A at 1000 V IEC), physical dimensions (2-position, 5.1 mm terminal width), termination method (screw), and safety certifications (UL94 V-0). The substitute part is mechanically and electrically compatible for applications originally specified with the DS20-BU.

Q: What is the difference in wire gauge acceptance between these two parts?

A: The DS20-BU accepts 12-22 AWG (0.5-2.5 mm²), while the Weidmüller 1412950000 accepts 12-30 AWG (0.05-4 mm²). The substitute part accommodates a wider conductor range, but both fully support the original DS20-BU specification range.

Q: Are there packaging differences between the DS20-BU and the Weidmüller substitute?

A: The DS20-BU packaging information is not specified in the original documentation. The Weidmüller 1412950000 is supplied in bulk packaging. Confirm packaging requirements for your specific procurement process.

Q: What is the stripping length requirement for each connector?

A: The DS20-BU requires 9 mm stripping length, while the Weidmüller 1412950000 requires 10 mm. Ensure conductor preparation follows the appropriate specification for the selected component.

Q: Is the Weidmüller part RoHS compliant?

A: Yes, the Weidmüller 1412950000 is RoHS compliant. RoHS compliance status for the original DS20-BU is not specified in the available documentation.
