DD200 Equivalent & Substitute Parts Reference

Part Overview

The DD200 is a 200A 415 VAC fuse cartridge with bolt mount configuration, manufactured by Eaton - Bussmann Electrical Division. This component is classified as obsolete, though 1111 pieces remain available in new original stock. The DD200 serves critical electrical and industrial protection applications requiring high current interruption capacity at 80kA breaking capacity.

Due to its obsolete product status, identifying active equivalent parts ensures supply chain continuity and access to current manufacturing support. The DD200M250 represents the active production equivalent within the same DD series.

Key Parameters

Substitute Part Grouping Explanation

Substitution between DD200 and DD200M250 is based on the following matching electrical and mechanical parameters:

• Current Rating: Both rated at 200A
• Voltage Rating: Both rated at 415 VAC
• Fuse Type: Both are cartridge fuses
• Mounting Type: Both use bolt mount configuration
• Package / Case: Both feature cylindrical blade terminal (bolt) design
• Physical Dimensions: Identical at 1.220" Dia x 1.850" L (31.00mm x 47.00mm)
• Breaking Capacity: Both provide 80kA interruption capacity
• Series: Both belong to the DD series
• Manufacturer: Both manufactured by Eaton - Bussmann Electrical Division
• Application Domain: Both serve electrical and industrial applications

The primary distinction between these parts lies in product status and melting I²t characteristics, which do not affect mechanical or primary electrical interchangeability for standard circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

The DD200M250 is the direct active equivalent for the obsolete DD200. Both components share identical electrical ratings, mechanical dimensions, and breaking capacity specifications, ensuring drop-in compatibility in existing circuit protection installations.

Selection between these parts should be based on product availability and supply chain requirements:

• DD200: Available in existing inventory (1111 pieces). Suitable for immediate replacement needs where obsolete stock is acceptable.
• DD200M250: Active production status with current manufacturing support (1119 pieces in stock). Recommended for new designs, long-term supply assurance, and applications requiring RoHS compliance documentation.

The DD200M250 exhibits a higher melting I²t value (200000 versus 120000), indicating a different thermal response characteristic. This parameter difference does not affect mechanical interchangeability but may influence thermal protection behavior in specific circuit configurations.

Frequently Asked Questions (FAQ)

Q: Can DD200M250 be used as a direct replacement for DD200?

A: Yes. Both components are mechanically and electrically identical in all critical parameters: 200A current rating, 415 VAC voltage rating, bolt mount configuration, cylindrical blade terminal design, and 80kA breaking capacity. Physical dimensions are identical at 1.220" Dia x 1.850" L.

Q: What is the difference between DD200 and DD200M250?

A: The primary differences are product status (DD200 is obsolete; DD200M250 is active) and melting I²t rating (120000 versus 200000). Both differences relate to manufacturing lifecycle and thermal response characteristics, not to mechanical or primary electrical interchangeability.

Q: Why is DD200 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. However, existing inventory remains available. The DD200M250 represents the current production equivalent within the DD series.

Q: Are there any compliance differences between these parts?

A: DD200M250 carries RoHS Compliant certification, while DD200 compliance status is not specified. Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications.

Q: What packaging options are available?

A: DD200 is supplied in standard packaging. DD200M250 is available in bulk packaging, which may affect ordering quantities and logistics considerations.

Q: Are these parts suitable for motor protection applications?

A: DD200M250 is explicitly listed for motor protection applications. DD200 specifications list electrical and industrial applications. Both components provide the 80kA breaking capacity required for industrial circuit protection.
