DP100-GY Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The DP100-GY 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 3-14 AWG range with electrical ratings of 101 A (IEC) / 100 A (UL) at 1000V (IEC) / 600V (UL). The DP100-GY is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new designs requiring compatible components.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DP100-GY is determined by the following critical parameters:

• Connector Type & Configuration: Feed-through terminal block with 2 positions, 1 level, and 12.0 mm terminal width
• Termination Method: Screw termination
• Electrical Ratings: Current and voltage ratings must meet or exceed IEC 101 A / 1000 V and UL 100 A / 600 V
• Wire Gauge Compatibility: Acceptable wire gauge range must accommodate the 3-14 AWG (1.5-25 mm²) specification
• Physical & Material Specifications: Gray color, polyamide insulation, UL94 V-0 flammability rating, 12 mm stripping length
• Regulatory Compliance: RoHS compliance and MSL rating of 1

The substitute part 10134255-001LF from Amphenol Anytek meets the core structural and electrical requirements with the following considerations: it accepts 4-14 AWG wire (narrower minimum gauge), maintains 2-position feed-through configuration with identical terminal width and screw termination, and achieves equivalent IEC electrical ratings. However, the UL current rating is reduced to 85 A, and the flammability rating is UL94 V-2 rather than V-0.

Parameter Comparison

Engineering Selection Recommendations

The 10134255-001LF from Amphenol Anytek provides functional equivalence for applications where the following conditions are met:

• Wire gauge requirements do not include 3 AWG conductors (substitute minimum is 4 AWG)
• UL current rating of 85 A is sufficient for the application (original specification is 100 A)
• UL94 V-2 flammability rating meets system safety requirements (original specification is V-0)

The substitute part maintains identical IEC electrical ratings, physical dimensions, termination method, and connector configuration. Its active product status ensures ongoing availability and supply chain continuity compared to the obsolete DP100-GY. Both components meet RoHS and MSL requirements and are suitable for industrial terminal block applications.

For applications requiring the original DP100-GY specifications without compromise, including 3 AWG wire gauge support, 100 A UL current rating, and UL94 V-0 flammability rating, alternative sources or design modifications may be necessary.

Frequently Asked Questions (FAQ)

Q: Can the 10134255-001LF directly replace the DP100-GY in all applications?

A: Direct replacement is possible only if the application does not require 3 AWG wire gauge termination, does not exceed 85 A at UL ratings, and accepts UL94 V-2 flammability performance. For applications meeting these conditions, the substitute provides equivalent feed-through terminal block functionality with identical physical and IEC electrical specifications.

Q: What is the significance of the wire gauge difference (3-14 AWG vs. 4-14 AWG)?

A: The DP100-GY accepts 3 AWG conductors; the 10134255-001LF minimum is 4 AWG. This difference is material only if the system design requires termination of 3 AWG wire. For 4-14 AWG applications, both components are compatible.

Q: Why is the UL current rating different between the two parts?

A: The DP100-GY is rated 100 A (UL); the 10134255-001LF is rated 85 A (UL). This reflects different design or testing criteria by the respective manufacturers. System designs operating at or near 100 A UL must confirm that 85 A is acceptable, or select an alternative component.

Q: What does the flammability rating difference mean for component selection?

A: The DP100-GY carries UL94 V-0 rating; the 10134255-001LF carries UL94 V-2. V-0 indicates superior flame resistance. Applications in high-temperature or fire-critical environments may require V-0 compliance, making the substitute unsuitable. Standard industrial applications typically accept V-2 performance.

Q: Is the 10134255-001LF suitable for new designs?

A: Yes. The substitute is in active production status, ensuring supply availability. It meets RoHS3 and MSL requirements. Selection should be based on the specific electrical, wire gauge, and flammability requirements of the application.

Q: Are there mechanical compatibility concerns between the two parts?

A: No. Both components share identical terminal width (12.0 mm), stripping length (12 mm), 2-position configuration, and screw termination method. Mechanical fit and installation procedures are equivalent.
