Key Parameters

Substitute Part Grouping Explanation

The 2D05UM qualifies as a parametric equivalent to the 2E05UM based on the following matching electrical and mechanical specifications:

• Identical breaker type: Thermal Magnetic
• Identical current rating: 500mA
• Identical AC voltage rating: 480V
• Identical DC voltage rating: 80V
• Identical mounting configuration: DIN Rail
• Identical actuator mechanism: Lever
• Identical pole count: 2 poles
• Same product series: V-EA
• Matching regulatory approvals: CSA, UL508 (2D05UM includes additional VDE certification)
• Identical RoHS3 compliance status
• Identical REACH status

Both parts maintain the same base electrical performance envelope and mechanical form factor, permitting direct substitution in applications where these parameters define the functional requirement.

Parameter Comparison

Engineering Selection Recommendations

Both the 2E05UM and 2D05UM are Active status products with full regulatory compliance. The 2D05UM provides extended certification coverage through VDE approval in addition to CSA and UL508 certifications. Selection between these parts should be based on:

• Geographic regulatory requirements: 2D05UM supports additional European compliance through VDE certification
• Supply chain availability: 2E05UM currently maintains 1145 units in stock; 2D05UM maintains 676 units in stock
• Application-specific certification mandates: Both satisfy North American standards; 2D05UM extends to European markets

No electrical or mechanical performance differentiation exists between these parts. Both are ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can the 2D05UM directly replace the 2E05UM in existing installations?

A: Yes. All electrical parameters (current rating, voltage ratings, breaker type) and mechanical specifications (mounting, actuator, pole count) are identical. Direct substitution is permissible without circuit redesign.

Q: What is the difference between these two part numbers?

A: The primary difference is regulatory certification scope. The 2D05UM includes VDE certification in addition to CSA and UL508 approvals, making it suitable for applications requiring European compliance. Electrical and mechanical performance are identical.

Q: Are there any packaging or inventory considerations?

A: Both parts are supplied in Bulk packaging. The 2E05UM has higher current inventory (1145 units) compared to the 2D05UM (676 units). Lead time and availability may differ based on supplier stock levels.

Q: Do these parts share the same base product number?

A: No. The 2E05UM has base product number 2E05, while the 2D05UM has base product number 2D05. Despite different base designations, they maintain identical electrical and mechanical specifications within the V-EA series.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 2E05UM and 2D05UM are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.
