DP35-GY Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The DP35-GY 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 electrical performance of 32 A (IEC) / 35 A (UL) and 630 V (IEC) / 600 V (UL). The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where legacy compatibility is not required.

Substitute Part Grouping Explanation

Substitution of the DP35-GY is determined by the following critical parameters that must be maintained or exceeded:

Electrical Performance: Current rating (IEC/UL) and voltage rating (IEC/UL) must meet or exceed the original specification
Physical Configuration: 2-position, 1-level feed-through design with 6.1 mm terminal width
Termination Method: Screw termination required
Wire Gauge Compatibility: Acceptable wire gauge range must encompass the original 10-22 AWG specification
Compliance & Safety: UL94 V-0 flammability rating and RoHS compliance required

The substitute part 1037800000 (Weidmüller W series) meets these criteria with equivalent or superior electrical ratings, compatible physical dimensions, and maintained safety certifications.

Engineering Selection Recommendations

The Weidmüller 1037800000 terminal block connector is a direct functional equivalent to the DP35-GY. Both components maintain identical electrical performance under IEC and UL standards, share the same physical footprint and terminal geometry, and employ identical screw termination methodology.

The substitute part offers extended wire gauge accommodation (10-26 AWG versus 10-22 AWG) and elevated IEC voltage rating (800 V versus 630 V), both of which provide additional operational margin without introducing incompatibility. Both components carry UL94 V-0 flammability certification and RoHS compliance status.

The critical distinction is product lifecycle status: the DP35-GY is obsolete while the 1037800000 maintains active production status, ensuring long-term availability and supply chain continuity for new installations and system replacements.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1037800000 be used as a direct replacement for the DP35-GY in existing installations?

A: Yes. Both components share identical electrical ratings (32 A IEC, 35 A UL), voltage specifications (630 V IEC, 600 V UL), physical dimensions (6.1 mm terminal width), and screw termination design. The substitute part is mechanically and electrically interchangeable.

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

A: The Weidmüller 1037800000 accommodates 10-26 AWG (0.5-6 mm²) compared to the DP35-GY specification of 10-22 AWG (0.5-4 mm²). This extended range does not affect compatibility with the original 10-22 AWG application range and provides flexibility for future conductor sizing within the same terminal block footprint.

Q: Are there compliance or certification differences between these components?

A: Both components carry identical UL94 V-0 flammability ratings and RoHS compliance status. The Weidmüller part additionally specifies REACH Unaffected status. No compliance gaps exist between the two components.

Q: What is the practical impact of the higher IEC voltage rating on the substitute part?

A: The Weidmüller 1037800000 is rated for 800 V (IEC) versus the DP35-GY rating of 630 V (IEC). This represents a 27% margin increase and does not introduce any incompatibility with systems designed for the original 630 V specification. The higher rating provides additional safety margin in voltage-stressed applications.

Q: How do the insulation materials differ between these components?

A: The DP35-GY uses Polyamide (PA66) / Nylon 6/6 insulation, while the Weidmüller 1037800000 specifies Thermoplastic / Wemid insulation. Both materials achieve UL94 V-0 flammability performance and are suitable for the specified electrical and thermal operating conditions.
