DP45-YW Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The DP45-YW 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 8-20 AWG range with electrical ratings of 41 A (IEC) / 45 A (UL) at 500V (IEC) / 600V (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 eligibility for the DP45-YW is determined by the following critical parameters:

• Mechanical Compatibility: 2 positions, 1 level, 8.0 mm terminal width, feed-through configuration, screw termination
• Electrical Compatibility: Current and voltage ratings must meet or exceed IEC and UL specifications (41 A / 500V IEC minimum; 45 A / 600V UL minimum)
• Wire Gauge Compatibility: Wire gauge range must accommodate 8-20 AWG (0.5-6 mm²) conductors
• Material & Safety: Polyamide insulation with UL94 V-0 flammability rating
• Physical Specifications: 12 mm stripping length, yellow color designation

The ATB6Y from Amphenol PCD meets these substitution criteria with compatible mechanical form factor, equivalent or superior electrical ratings, and matching material specifications.

Parameter Comparison

Engineering Selection Recommendations

The ATB6Y from Amphenol PCD is a direct functional equivalent for the obsolete DP45-YW. Selection is based on the following engineering criteria:

Mechanical Compatibility: Both connectors share identical 2-position, 1-level feed-through architecture with 8.0 mm terminal width and screw termination, ensuring direct form-factor compatibility in existing installations.

Electrical Performance: The ATB6Y meets or exceeds all electrical specifications of the DP45-YW. IEC current rating is identical at 41 A, while IEC voltage rating increases from 500V to 800V. UL current rating increases from 45 A to 50 A, with UL voltage rating maintained at 600V. These characteristics ensure the substitute part operates safely within or above the original design envelope.

Wire Gauge Accommodation: The ATB6Y accommodates 8-22 AWG (1.5-6 mm²), which covers the original 8-20 AWG specification. The extended upper range provides additional flexibility for future applications.

Material & Safety Compliance: Both connectors utilize identical Polyamide (PA66) insulation material with UL94 V-0 flammability rating, ensuring equivalent thermal and fire safety performance. The ATB6Y carries active RoHS compliance certification, meeting current regulatory requirements.

Product Availability: The ATB6Y is an active product with 1066 units in stock, providing reliable supply continuity for the obsolete DP45-YW.

Frequently Asked Questions (FAQ)

Q: Can the ATB6Y directly replace the DP45-YW in existing installations?

A: Yes. The ATB6Y is mechanically and electrically compatible with the DP45-YW. Both connectors feature identical 2-position feed-through configuration, 8.0 mm terminal width, screw termination, and 12 mm stripping length. Electrical ratings of the ATB6Y meet or exceed the DP45-YW specifications.

Q: What is the wire gauge compatibility between these connectors?

A: The DP45-YW accepts 8-20 AWG (0.5-6 mm²). The ATB6Y accepts 8-22 AWG (1.5-6 mm²). The ATB6Y covers the full operational range of the DP45-YW with an extended upper limit, making it suitable for all applications originally designed for the DP45-YW.

Q: Are the electrical ratings of the ATB6Y sufficient for DP45-YW applications?

A: Yes. The ATB6Y meets or exceeds all electrical specifications. IEC ratings are identical (41 A / 800V vs. 41 A / 500V), with the ATB6Y providing higher voltage margin. UL ratings show the ATB6Y at 50 A / 600V compared to the DP45-YW at 45 A / 600V, providing additional current capacity.

Q: Do both connectors use the same insulation material?

A: Yes. Both the DP45-YW and ATB6Y use Polyamide (PA66) insulation with UL94 V-0 flammability rating, ensuring equivalent thermal and fire safety performance.

Q: What is the packaging difference between these parts?

A: The DP45-YW packaging is not specified in available documentation. The ATB6Y is supplied in Tray packaging. Verify packaging requirements for your specific assembly or procurement process.

Q: Is the ATB6Y RoHS compliant?

A: Yes. The ATB6Y is RoHS compliant, meeting current environmental and regulatory standards. RoHS compliance status for the DP45-YW is not specified.

Q: Are there any dimensional differences between the DP45-YW and ATB6Y?

A: Both connectors share identical critical dimensions: 2 positions, 1 level, 8.0 mm terminal width, and 12 mm stripping length. These specifications ensure direct mechanical compatibility.
