DP35-RD Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The DP35-RD 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 rated current capacity of 35 A (UL) and 32 A (IEC) at 600V (UL) and 630V (IEC) respectively. The product is currently classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring this terminal block specification.

Substitute Part Grouping Explanation

Substitution eligibility for the DP35-RD is determined by the following critical parameters:

Mechanical Compatibility: Number of positions (2), number of levels (1), terminal width (6.1 mm), and feed-through type must match exactly
Electrical Compatibility: Current and voltage ratings must meet or exceed the original specification for both UL and IEC standards
Termination Method: Screw termination style is required
Wire Gauge Acceptance: The substitute must accept the 10-22 AWG range of the original part; acceptance of additional wire gauges does not disqualify a substitute
Regulatory Compliance: RoHS compliance and UL94 V-0 flammability rating must be maintained

The Weidmüller part number 1020140000 qualifies as a substitute based on these criteria. It maintains identical mechanical configuration, meets or exceeds all electrical ratings, preserves termination method and compliance standards, and accepts the required wire gauge range while supporting an extended range.

Engineering Selection Recommendations

The Weidmüller 1020140000 terminal block connector is a qualified substitute for the obsolete Eaton DP35-RD. Selection should be based on the following factors:

Product Status: The DP35-RD is obsolete, making the active-status 1020140000 the appropriate choice for new designs and replacement applications.

Electrical Performance: The 1020140000 meets all UL and IEC electrical requirements of the original part, with IEC voltage rating exceeding the original specification (800V vs. 630V).

Mechanical Fit: Identical position count, level configuration, terminal width, and feed-through design ensure direct mechanical compatibility in existing mounting and wiring applications.

Regulatory Compliance: Both parts maintain RoHS compliance and UL94 V-0 flammability certification, satisfying regulatory requirements for the application.

Wire Gauge Capability: The extended wire gauge acceptance range (10-26 AWG vs. 10-22 AWG) of the substitute provides additional flexibility without compromising compatibility with the original specification range.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1020140000 be used as a direct replacement for the DP35-RD in existing installations?

A: Yes. The 1020140000 maintains identical mechanical configuration (2 positions, 1 level, 6.1 mm terminal width), matching electrical ratings (35 A UL / 32 A IEC, 600V UL / 630V IEC), and screw termination method. Physical mounting and wiring compatibility are preserved.

Q: What is the significance of the extended wire gauge range in the Weidmüller part?

A: The 1020140000 accepts 10-26 AWG (0.5-6 mm²) compared to the DP35-RD's 10-22 AWG (0.5-4 mm²). This extended range does not affect compatibility with the original specification, as all wire gauges within the original range remain fully supported.

Q: Are there differences in insulation material between these parts?

A: Yes. The DP35-RD uses Polyamide (PA66) Nylon 6/6, while the 1020140000 uses Thermoplastic Wemid. Both materials achieve UL94 V-0 flammability rating and provide equivalent electrical and mechanical performance for this application.

Q: Does the higher IEC voltage rating of the 1020140000 affect compatibility?

A: No. The 1020140000's 800V IEC rating exceeds the DP35-RD's 630V IEC requirement, making it suitable for applications requiring the original specification. Higher voltage ratings do not create incompatibility.

Q: What packaging format is available for the Weidmüller substitute?

A: The 1020140000 is supplied in box packaging, with 1059 pieces available in current inventory.

Q: Are both parts RoHS compliant?

A: Yes. Both the DP35-RD and 1020140000 are RoHS compliant, meeting regulatory requirements for restricted substance elimination.
