Eaton Bussmann 14004-2 Equivalent & Substitute Parts

Part Overview

The Eaton Bussmann 14004-2 is a 2-circuit barrier block connector from the Magnum® 14004 series, designed for chassis and panel mounting applications. This terminal block features a 0.500" (12.70mm) pitch configuration with screw termination on top and closed bottom termination. The component is rated for 90A at 600V and accommodates wire gauges from 4-14 AWG. As an active product with ROHS3 compliance, the 14004-2 remains in production. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and application requirements where alternative mounting configurations or electrical ratings may be acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 14004-2 is determined by the following critical parameters:

• Terminal Block Type: Must be Barrier Block with screw termination
• Number of Circuits: Must be 2 circuits
• Voltage Rating: Must be 600V or higher
• Bottom Termination: Must be Closed
• Barrier Type: Must be Enclosed
• Compliance: Must maintain ROHS3 compliance

The Curtis Industries 071022000 qualifies as a substitute based on matching terminal block type, circuit count, voltage rating, termination style, and barrier configuration. However, differences exist in pitch spacing (0.629" vs. 0.500"), current rating range, wire gauge accommodation, mounting type, and operating temperature. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the Eaton Bussmann 14004-2 and Curtis Industries 071022000 maintain active product status with ROHS3 compliance, supporting long-term availability and regulatory adherence. Selection between these components depends on application-specific constraints:

The 14004-2 is the primary choice for applications requiring 0.500" pitch spacing and chassis or panel mounting configurations with a 75°C operating temperature limit. The 071022000 serves applications where larger 0.629" pitch spacing, DIN rail or track mounting, and elevated operating temperatures up to 140°C are acceptable or required. The Curtis Industries part accommodates a broader wire gauge range (1-22 AWG) compared to the Eaton part (4-14 AWG), providing flexibility for applications using smaller or larger conductors. Current rating differences (90A for the 14004-2 versus 50A or 86A options for the 071022000) must align with circuit load requirements.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 071022000 directly replace the Eaton 14004-2 in existing designs?

A: Direct replacement requires verification of three factors: (1) PCB or mounting surface layout compatibility with the larger 0.629" pitch versus the original 0.500" pitch, (2) mounting hardware compatibility between chassis/panel mounting and DIN rail/track mounting systems, and (3) current load requirements alignment with the available 50A or 86A ratings. Physical and electrical integration must be confirmed before substitution.

Q: What are the key differences affecting substitution decisions?

A: The primary differences are pitch spacing (0.500" vs. 0.629"), mounting type (chassis/panel vs. DIN rail/track), operating temperature range (75°C vs. 140°C), and current rating options. These parameters determine whether the substitute part fits the physical installation and meets thermal and electrical performance requirements.

Q: Are both parts suitable for 600V applications?

A: Yes. Both the 14004-2 and 071022000 are rated for 600V operation and maintain ROHS3 compliance, supporting equivalent voltage-level applications.

Q: Which part accommodates a wider range of wire gauges?

A: The Curtis Industries 071022000 accommodates wire gauges from 1-22 AWG, compared to the Eaton 14004-2 range of 4-14 AWG. This broader range supports applications using smaller or larger conductors.

Q: What mounting configurations does each part support?

A: The Eaton 14004-2 supports chassis and panel mounting. The Curtis Industries 071022000 supports channel, DIN rail, and track mounting. Mounting type selection depends on the installation infrastructure available in the target application.
