DS50-YW Equivalent & Substitute Parts Reference

Part Overview

The DS50-YW 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 applications with wire gauges ranging from 8-20 AWG (0.5-6mm²). The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS50-YW is determined by the following critical parameters:

• Connector Type & Configuration: Feed-through terminal block with 2 positions and 1 level
• Terminal Dimensions: 8.0mm terminal width for mechanical compatibility
• Termination Method: Screw termination
• Electrical Ratings: Current and voltage ratings must meet or exceed application requirements
• Wire Gauge Compatibility: Wire gauge range must accommodate the intended conductor sizes
• Insulation Material & Flammability: Material composition and UL94 rating for safety compliance
• Physical Characteristics: Color and stripping length for installation consistency

The ATB6Y from Amphenol PCD meets these substitution criteria through matching connector type, terminal dimensions, termination style, and insulation material specifications.

Parameter Comparison

Engineering Selection Recommendations

The ATB6Y terminal block from Amphenol PCD serves as a direct functional equivalent to the obsolete DS50-YW. Selection of the ATB6Y is supported by the following engineering factors:

Electrical Compatibility: Both components maintain identical UL current (50 A) and voltage (600V) ratings. The IEC voltage rating of the ATB6Y (800V) is lower than the DS50-YW (1000V); applications requiring the full 1000V IEC rating must account for this difference.

Mechanical Compatibility: Identical terminal width (8.0mm), position count (2), and level configuration (1) ensure mechanical interchangeability within connector housings and mounting structures designed for the DS50-YW.

Material & Safety Compliance: Both components utilize identical insulation material (Polyamide PA66, Nylon 6/6) and share the same stripping length (12mm). The ATB6Y carries active RoHS compliance certification, whereas the DS50-YW status is not specified.

Wire Gauge Accommodation: The ATB6Y wire gauge range (8-22 AWG, 1.5-6mm²) encompasses the primary operating range of the DS50-YW (8-20 AWG, 0.5-6mm²), with extended capability for smaller gauge conductors.

Product Availability: The ATB6Y is actively manufactured and maintained in production inventory, providing long-term supply continuity compared to the obsolete DS50-YW.

Frequently Asked Questions (FAQ)

Q: Can the ATB6Y directly replace the DS50-YW in all applications?

A: The ATB6Y is mechanically and electrically compatible for applications operating within 600V UL or 800V IEC specifications. Applications requiring the full 1000V IEC rating of the DS50-YW require evaluation of the lower voltage rating of the ATB6Y.

Q: What is the significance of the wire gauge range difference between DS50-YW and ATB6Y?

A: The DS50-YW accommodates 8-20 AWG (0.5-6mm²), while the ATB6Y accommodates 8-22 AWG (1.5-6mm²). The ATB6Y covers the primary operating range of the DS50-YW and extends compatibility to smaller gauge conductors (22 AWG). The DS50-YW supports smaller cross-sections (0.5mm²) not covered by the ATB6Y.

Q: Are there packaging differences between these components?

A: The DS50-YW packaging specification is not provided. The ATB6Y is supplied in tray packaging. Packaging compatibility should be evaluated based on assembly and handling requirements.

Q: What compliance certifications apply to each component?

A: The ATB6Y carries RoHS compliance certification. The DS50-YW compliance status is not specified in the provided data. Both components carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications.

Q: Is the ATB6Y suitable for legacy system retrofits?

A: The ATB6Y is suitable for retrofitting legacy systems using the DS50-YW, provided the application voltage requirements do not exceed 600V UL or 800V IEC ratings. Mechanical mounting and electrical connection methods are compatible.
