DS50-GN Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The DS50-GN 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 8-20 AWG range with electrical ratings of 41 A (IEC) / 50 A (UL) and 1000 V (IEC) / 600 V (UL). The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and system continuity applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS50-GN is determined by the following critical parameters:

• Connector Configuration: 2-position, 1-level feed-through terminal block with screw termination
• Terminal Geometry: 8.0 mm terminal width for mechanical compatibility
• Electrical Performance: Current and voltage ratings must meet or exceed the original specification
• Wire Gauge Compatibility: Acceptable wire gauge range must accommodate the original 8-20 AWG specification
• Material and Safety Compliance: Polyamide insulation with UL94 V-0 flammability rating
• Physical Dimensions: Stripping length and overall form factor consistency

The ATB6G from Amphenol PCD meets these substitution criteria as an active product with equivalent mechanical and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ATB6G is a suitable substitute for the DS50-GN based on the following factors:

• Product Availability: The DS50-GN is obsolete; the ATB6G is an active product with current manufacturing support and documented availability.
• Mechanical Compatibility: Both connectors share identical 2-position, 1-level configuration with 8.0 mm terminal width and 12 mm stripping length, ensuring direct form-factor compatibility.
• Electrical Performance: Both parts meet the same UL current and voltage ratings (50 A / 600 V). The ATB6G IEC voltage rating of 800 V is lower than the DS50-GN's 1000 V; applications operating at or below 800 V IEC are fully compatible.
• Material and Safety: Both use Polyamide (PA66) insulation with identical moisture sensitivity levels. The ATB6G carries RoHS compliance certification, meeting current regulatory requirements.
• Wire Gauge Accommodation: The ATB6G accepts 8-22 AWG, which encompasses the original DS50-GN specification of 8-20 AWG.

For applications requiring the full 1000 V IEC rating, alternative substitutes with matching voltage specifications should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the ATB6G directly replace the DS50-GN in all applications?

A: The ATB6G is mechanically and electrically compatible for applications operating at or below 800 V IEC and 600 V UL. If your application requires the full 1000 V IEC rating of the original DS50-GN, the ATB6G is not suitable without system redesign or voltage derating.

Q: What is the significance of the wire gauge range difference (8-20 AWG vs. 8-22 AWG)?

A: The ATB6G accepts a wider wire gauge range (8-22 AWG) compared to the DS50-GN (8-20 AWG). This means the ATB6G can accommodate all wire sizes that the DS50-GN accepts, plus additional smaller gauges (21-22 AWG). For applications using 8-20 AWG conductors, both parts are fully compatible.

Q: Why is the IEC voltage rating different between these two parts?

A: The DS50-GN is rated for 1000 V IEC, while the ATB6G is rated for 800 V IEC. This difference reflects different design specifications and testing standards between manufacturers. Selection depends on your system's actual operating voltage.

Q: Are there packaging differences between the DS50-GN and ATB6G?

A: The DS50-GN packaging is not specified in the available data. The ATB6G is supplied in Tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: What does RoHS Compliant status mean for the ATB6G?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the ATB6G meets current environmental and safety regulations for electronic components, restricting the use of lead, cadmium, mercury, and other hazardous materials. This is a modern regulatory requirement not specified for the obsolete DS50-GN.

Q: Is the ATB6G the only substitute available?

A: The provided data identifies ATB6G as the documented substitute. Other equivalent parts may exist from different manufacturers; however, any alternative must meet the same critical parameters: 2-position feed-through configuration, 8.0 mm terminal width, screw termination, and appropriate electrical ratings for your application.
