DP150-BU Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The DP150-BU 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 electrical connections rated at 150 A (IEC/UL) and 1000V (IEC) / 600V (UL), accommodating wire gauges from 1/0 to 12 AWG (2.5–50 mm²). The DP150-BU has reached obsolete product status, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and new design applications where this connector type is specified.

Substitute Part Grouping Explanation

Substitution of the DP150-BU is determined by strict equivalence across the following critical parameters:

Connector Type & Configuration: Feed-through, 2-position, 1-level architecture
Electrical Ratings: 150 A current capacity (both IEC and UL standards) and voltage ratings of 1000 V (IEC) / 600 V (UL)
Mechanical Interface: 16.0 mm terminal width and screw termination style
Wire Compatibility: Support for wire gauges spanning 1/0 to 12 AWG minimum (2.5–50 mm² cross-section)
Material & Safety Compliance: Polyamide insulation with UL94 V-0 flammability rating and RoHS compliance

The Phoenix Contact 3047727 (CLIPLINE UT series) meets all substitution criteria. While it specifies a wire gauge range of 1/0–14 AWG (1.5–50 mm²), this represents an extended lower-gauge capability that maintains full compatibility with the DP150-BU's specified range. Both connectors share identical electrical ratings, terminal geometry, termination method, and regulatory compliance status.

Engineering Selection Recommendations

The Phoenix Contact 3047727 is a direct functional equivalent for the obsolete DP150-BU. Both components satisfy identical electrical performance requirements (150 A, 1000 V IEC / 600 V UL) and mechanical specifications (2-position, 16.0 mm terminal width, screw termination).

The 3047727 offers the advantage of active product status, ensuring ongoing availability and manufacturer support. Its extended wire gauge capability (1/0–14 AWG versus 1/0–12 AWG) provides additional flexibility for smaller-gauge applications while maintaining full compatibility with the DP150-BU's specified range.

Both components carry equivalent regulatory compliance: UL94 V-0 flammability rating, RoHS certification (the 3047727 meets ROHS3, the current iteration), and MSL 1 moisture sensitivity rating. Packaging differences (the DP150-BU is listed as standard; the 3047727 is supplied in bulk) do not affect functional or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3047727 directly replace the DP150-BU in existing installations?

A: Yes. Both connectors share identical electrical ratings (150 A, 1000 V IEC / 600 V UL), mechanical dimensions (16.0 mm terminal width), and termination method (screw). The 3047727 is a functional equivalent suitable for direct substitution.

Q: What is the significance of the extended wire gauge range (1/0–14 AWG) on the 3047727?

A: The 3047727 supports gauges down to 14 AWG, compared to the DP150-BU's 12 AWG minimum. This extended range does not affect compatibility with the DP150-BU's specified 1/0–12 AWG range; it simply provides additional flexibility for smaller-gauge applications if needed in future designs.

Q: Are there any compliance or certification differences between these two connectors?

A: Both connectors meet UL94 V-0 flammability requirements and carry RoHS certification. The 3047727 is certified to ROHS3 (the current RoHS standard), while the DP150-BU meets the earlier RoHS Compliant designation. Both are MSL 1 rated with unlimited moisture sensitivity tolerance.

Q: Why is the DP150-BU listed as obsolete?

A: Obsolete status indicates the DP150-BU is no longer manufactured by Eaton. The Phoenix Contact 3047727 remains in active production, making it the recommended alternative for new designs and ongoing component sourcing.

Q: Does packaging format affect electrical or mechanical performance?

A: No. The DP150-BU standard packaging and the 3047727 bulk packaging are logistical differences only. Electrical ratings, mechanical dimensions, and functional performance are identical.

Q: Are there any dimensional or mounting differences that would require design changes?

A: No. Both connectors feature identical terminal width (16.0 mm), 2-position configuration, and screw termination geometry. Direct mechanical substitution is possible without design modification.
