DS30-GY Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The DS30-GY 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 10-22 AWG range with rated electrical performance of 32 A (IEC) / 30 A (UL) at 1000V (IEC) / 600V (UL). The DS30-GY is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this connector type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS30-GY is determined by strict equivalence across the following critical parameters:

Position and Configuration Match: The substitute must maintain 2 positions, 1 level, and feed-through type to ensure mechanical and electrical compatibility within the same circuit topology.

Electrical Performance: The substitute must meet or exceed the IEC current rating of 32 A and IEC voltage rating of 1000 V. UL ratings of 30 A at 600 V establish the minimum acceptable performance for North American applications.

Termination and Wire Compatibility: Screw termination style is mandatory. The substitute wire gauge range must encompass the 10-22 AWG specification of the original part, or provide a range that fully contains this specification without restriction.

Terminal Geometry: Terminal width of 6.1 mm ensures mechanical fit within existing mounting and connection infrastructure.

Material and Safety Compliance: UL94 V-0 flammability rating is required. Insulation material must provide equivalent electrical and thermal properties.

The Weidmüller 1037800000 qualifies as a substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1037800000 is an active-status substitute for the obsolete DS30-GY. Both components share identical mechanical configuration (2 positions, 1 level, 6.1 mm terminal width) and screw termination methodology, ensuring direct functional replacement in existing installations.

Electrical performance is equivalent for UL applications (600 V, 30-35 A range). The IEC voltage rating of the Weidmüller part is 800 V compared to the DS30-GY's 1000 V; this difference must be evaluated against the specific voltage requirements of the application. For circuits operating at or below 800 V IEC, the Weidmüller component provides equivalent performance.

Wire gauge compatibility is enhanced with the Weidmüller part, which accepts 10-26 AWG (0.5-6 mm²) compared to the DS30-GY's 10-22 AWG (0.5-4 mm²). This expanded range provides greater flexibility for conductor selection while maintaining full compatibility with the original 10-22 AWG specification.

Both components meet UL94 V-0 flammability requirements. The Weidmüller part carries RoHS compliance certification, which may be required for new designs or regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1037800000 directly replace the DS30-GY in all applications?

A: Direct replacement is possible for applications operating at or below 800 V IEC. The DS30-GY is rated for 1000 V IEC; if your circuit requires this higher voltage rating, the Weidmüller substitute is not appropriate. For 600 V UL applications, the Weidmüller part exceeds the original specification (35 A vs. 30 A).

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

A: The Weidmüller 1037800000 accepts 10-26 AWG compared to the DS30-GY's 10-22 AWG. This expanded range does not affect compatibility with the original 10-22 AWG specification; it simply provides additional flexibility for future applications using finer gauge conductors.

Q: Are there mechanical compatibility concerns between these two parts?

A: No. Both components share identical terminal width (6.1 mm), position count (2), level count (1), and feed-through configuration. Mounting and connection infrastructure designed for the DS30-GY will accommodate the Weidmüller substitute without modification.

Q: What is the difference in stripping length between these parts?

A: The DS30-GY requires 9 mm stripping length; the Weidmüller part requires 10 mm. This 1 mm difference is a minor preparation variation and does not affect electrical or mechanical performance.

Q: Does RoHS compliance status affect substitution decisions?

A: RoHS compliance is a regulatory and supply chain consideration rather than a functional performance factor. The Weidmüller part's RoHS compliance may be advantageous for new designs or applications subject to environmental regulations, but it does not impact electrical or mechanical compatibility with the DS30-GY.
