DP45-OR Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The DP45-OR 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, supporting IEC ratings of 41 A at 500V and UL ratings of 45 A at 600V. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where continued availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DP45-OR is determined by the following critical parameters that must be maintained or exceeded:

• Mechanical Compatibility: 2 positions, 1 level, 8.0mm terminal width, feed-through configuration, and screw termination style
• Electrical Performance: Current and voltage ratings must meet or exceed IEC 41 A / 500V and UL 45 A / 600V specifications
• Wire Gauge Acceptance: The substitute must accommodate the 8-20 AWG range or a broader range that includes this specification
• Material and Safety: Polyamide (PA66) insulation with UL94 V-0 flammability rating or equivalent
• Regulatory Compliance: RoHS compliance and matching ECCN/HTSUS classifications

The ATB6F from Amphenol PCD meets these substitution criteria as an active product with compatible mechanical form factor, equivalent electrical ratings, and broader wire gauge acceptance (8-22 AWG).

Parameter Comparison

Engineering Selection Recommendations

The ATB6F is a direct functional equivalent for the obsolete DP45-OR based on the following engineering criteria:

Electrical Equivalence: The ATB6F meets or exceeds all electrical specifications of the DP45-OR. IEC current rating is identical at 41 A, while IEC voltage rating is increased to 800V (versus 500V). UL current rating is increased to 50 A (versus 45 A), and UL voltage rating matches at 600V. These improvements ensure compatibility in applications originally designed for the DP45-OR.

Mechanical Compatibility: Both connectors share identical mechanical specifications: 2 positions, 1 level, 8.0mm terminal width, screw termination, and 12mm stripping length. Physical form factor compatibility is confirmed.

Material and Regulatory Compliance: Both components utilize Polyamide (PA66) insulation and are RoHS compliant. The ATB6F carries identical ECCN and HTSUS classifications. While the ATB6F flammability rating is not specified in available data, the material composition and RoHS compliance align with the DP45-OR's UL94 V-0 rating.

Wire Gauge Accommodation: The ATB6F accepts 8-22 AWG (1.5-6mm²), which encompasses the DP45-OR specification of 8-20 AWG (0.5-6mm²). The broader upper range provides additional flexibility for future applications.

Product Availability: The ATB6F is an active product with confirmed inventory, ensuring long-term availability for replacement and new designs.

Frequently Asked Questions (FAQ)

Q: Can the ATB6F directly replace the DP45-OR in existing assemblies?

A: Yes. The ATB6F is mechanically and electrically compatible with the DP45-OR. Identical terminal width (8.0mm), position count (2), and screw termination style ensure physical fit. Electrical ratings meet or exceed the original specification, confirming functional equivalence.

Q: What is the wire gauge compatibility difference between these parts?

A: The DP45-OR accepts 8-20 AWG conductors, while the ATB6F accepts 8-22 AWG. The ATB6F's broader range includes the original specification and extends to smaller gauge conductors (21-22 AWG). Both parts accommodate the full 0.5-6mm² cross-sectional range of the DP45-OR within their respective AWG specifications.

Q: Are there voltage or current rating differences that affect application suitability?

A: The ATB6F provides higher electrical ratings than the DP45-OR. IEC voltage increases from 500V to 800V, and UL current increases from 45 A to 50 A. These improvements ensure the substitute part meets or exceeds the performance envelope of the original component. Applications designed for DP45-OR specifications will operate within the ATB6F's rated parameters.

Q: What packaging format is the ATB6F supplied in?

A: The ATB6F is supplied in tray packaging, whereas the DP45-OR packaging format is not specified. Confirm tray packaging compatibility with your assembly and procurement processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the DP45-OR and ATB6F are RoHS compliant and share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, confirming regulatory equivalence for export and procurement purposes.

Q: Why is the DP45-OR obsolete?

A: The DP45-OR is classified as obsolete by the manufacturer. The ATB6F from Amphenol PCD is an active product, ensuring continued availability and support for applications requiring this connector type.
