DS30-BU Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The DS30-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 rated for 10-22 AWG wire gauges with screw termination and is designed for applications requiring 32 A (IEC) / 30 A (UL) current capacity at 1000V (IEC) / 600V (UL). The DS30-BU is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs requiring compatible feed-through terminal block functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS30-BU is determined by the following critical parameters:

• Connector Type & Configuration: Feed-through terminal block with 2 positions, 1 level, and 6.1 mm terminal width
• Termination Method: Screw termination
• Electrical Ratings: Minimum 32 A (IEC) and 1000 V (IEC) capability; minimum 30 A (UL) and 600 V (UL) capability
• Wire Gauge Compatibility: Support for 10-22 AWG wire range (0.5-4 mm²) or broader compatible range
• Physical & Material Specifications: Blue color, UL94 V-0 flammability rating, polyamide or equivalent thermoplastic insulation

The substitute part 1020180000 (Weidmüller W series) meets these criteria with equivalent or superior electrical ratings and compatible wire gauge range.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1020180000 is a direct functional substitute for the obsolete DS30-BU. Both components share identical 2-position, feed-through configuration with 6.1 mm terminal width and screw termination. The 1020180000 maintains equivalent IEC current rating (32 A) and UL voltage rating (600 V), with superior UL current rating (35 A vs. 30 A). The wire gauge range is extended (10-26 AWG vs. 10-22 AWG), providing broader compatibility with smaller gauge conductors. Both components carry UL94 V-0 flammability certification and unlimited moisture sensitivity level (MSL 1).

The primary consideration is the IEC voltage rating differential: the 1020180000 is rated 800 V (IEC) compared to the DS30-BU at 1000 V (IEC). This difference must be evaluated against specific application voltage requirements. The 1020180000 is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1020180000 directly replace the DS30-BU in all applications?

A: The 1020180000 is functionally equivalent for applications operating at or below 800 V (IEC) or 600 V (UL). Applications requiring the full 1000 V (IEC) rating of the DS30-BU require voltage compatibility verification before substitution.

Q: What is the significance of the extended wire gauge range (10-26 AWG) in the 1020180000?

A: The extended range accommodates smaller gauge conductors (24-26 AWG) beyond the DS30-BU specification (10-22 AWG). This provides design flexibility for applications using finer wire gauges within the 0.5-6 mm² cross-section range.

Q: Are there physical mounting or footprint differences between these components?

A: Both components share identical 2-position configuration, 1-level design, and 6.1 mm terminal width. The stripping length differs slightly (10 mm vs. 9 mm), which may require minor wire preparation adjustment but does not affect mechanical mounting compatibility.

Q: What certifications apply to both components?

A: Both the DS30-BU and 1020180000 carry UL94 V-0 flammability certification, indicating compliance with flame propagation standards. Both are classified as MSL 1 (Unlimited), requiring no special moisture handling during storage or installation.

Q: Why is product status relevant to component selection?

A: The DS30-BU is obsolete, indicating discontinued manufacturing and potential supply unavailability. The 1020180000 is in active production, ensuring reliable sourcing for current and future applications.
