DP35-BU Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The DP35-BU is a 2-position feed-through terminal block connector manufactured by Eaton - Bussmann Electrical Division, part of the Magnum® DP series. This component is designed for screw termination of conductors in the 10-22 AWG range with electrical ratings of 32 A (IEC) / 35 A (UL) and 630 V (IEC) / 600 V (UL). The product is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system continuity and ensure design compatibility when the original part is no longer available from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DP35-BU are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type & Configuration: Feed-through terminal block with 2 positions and 1 level
• Termination Method: Screw termination
• Terminal Geometry: 6.1 mm terminal width
• Electrical Ratings: Current capacity (32 A IEC minimum) and voltage capacity (630 V IEC minimum)
• Wire Gauge Compatibility: Support for 10-22 AWG conductor range (0.5-4 mm²)
• Insulation & Safety: UL94 V-0 flammability rating and RoHS compliance
• Color Coding: Blue housing for visual identification

The substitute part 1020180000 (Weidmüller W series) meets or exceeds these core parameters, with the exception of wire gauge range extension (10-26 AWG) and enhanced voltage rating (800 V IEC), both of which represent improvements over the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1020180000 terminal block connector is a direct functional substitute for the obsolete DP35-BU. Both components share identical core specifications for position count, terminal geometry, termination method, and electrical ratings within the UL standard (35 A, 600 V). The Weidmüller part maintains full compliance with RoHS and UL94 V-0 flammability requirements.

The substitute part offers two technical advantages: an increased IEC voltage rating (800 V versus 630 V) and an extended wire gauge acceptance range (10-26 AWG versus 10-22 AWG). These enhancements do not introduce incompatibility; they expand the operational envelope of the substitute part. The active product status of the Weidmüller component ensures ongoing availability and supply chain continuity.

Physical compatibility is maintained through identical terminal width (6.1 mm), screw termination interface, and blue color coding. Both parts are packaged for industrial distribution and meet the same regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1020180000 be used as a direct replacement for the DP35-BU in existing designs?

A: Yes. The substitute part meets all core electrical and mechanical specifications of the original component. Identical current ratings (32 A IEC, 35 A UL), voltage ratings (630 V IEC, 600 V UL), terminal geometry (6.1 mm width), and screw termination interface ensure functional compatibility. The extended wire gauge range and higher IEC voltage rating of the substitute do not create incompatibility.

Q: What is the significance of the extended wire gauge range (10-26 AWG) on the Weidmüller part?

A: The substitute part accepts conductors from 10 AWG to 26 AWG, compared to the original 10-22 AWG range. This extension allows the Weidmüller connector to accommodate smaller gauge conductors (24-26 AWG) without requiring a different component. For applications using only 10-22 AWG conductors, this difference is not relevant to compatibility.

Q: Does the higher IEC voltage rating (800 V) on the Weidmüller part affect compatibility?

A: No. A higher voltage rating on the substitute part represents an improvement and does not create incompatibility. If the original design operates at 630 V IEC or lower, the Weidmüller part's 800 V rating provides additional safety margin. The UL voltage rating remains identical at 600 V.

Q: Are there packaging differences between the two parts?

A: The DP35-BU packaging information is not specified in the original documentation. The Weidmüller 1020180000 is supplied in box packaging. Confirm packaging requirements with your procurement or assembly process.

Q: What is the significance of the different insulation materials (Polyamide PA66 versus Thermoplastic Wemid)?

A: Both materials meet the UL94 V-0 flammability standard and provide equivalent electrical insulation performance. The material difference reflects different manufacturing approaches by each supplier but does not affect functional compatibility or safety ratings.

Q: Is the Weidmüller part currently available?

A: Yes. The Weidmüller 1020180000 is classified as an active product, ensuring ongoing availability and supply chain support, unlike the obsolete DP35-BU.
