Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0MIB025.X is determined by the following critical parameters:

• Current Rating: 25A (exact match required)
• Voltage Rating - DC: 12V minimum (higher ratings acceptable within system design limits)
• Actuator Type: Automatic Reset (functional requirement)
• Number of Poles: 1 (circuit configuration requirement)
• Mounting Type: Holder (mechanical interface requirement)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The substitute part 1620-2-25A from E-T-A meets these core substitution criteria. While the voltage rating differs (14.5V DC versus 12V DC), the higher rating is compatible with 12V applications. The thermal breaker type represents a different actuation mechanism but maintains the same automatic reset functionality and current rating.

Parameter Comparison

Engineering Selection Recommendations

The 1620-2-25A from E-T-A serves as a direct functional substitute for the obsolete 0MIB025.X. Both parts maintain ROHS3 compliance and share identical current ratings, pole configuration, and automatic reset functionality. The E-T-A part's higher DC voltage rating (14.5V) is compatible with 12V system applications. Both parts are classified as end-of-life products, indicating limited future availability through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the 1620-2-25A replace the 0MIB025.X in existing designs? A: Yes. The 1620-2-25A meets all critical substitution parameters: 25A current rating, automatic reset actuation, single-pole configuration, and holder mounting. The higher voltage rating is compatible with 12V applications.

Q: What is the difference between the breaker types? A: The 0MIB025.X breaker type is not specified in available documentation. The 1620-2-25A uses thermal actuation. Both maintain automatic reset functionality at the specified 25A current rating.

Q: Are there compliance concerns with substitution? A: Both parts are ROHS3 compliant. No compliance barriers exist for substitution in regulated applications.

Q: What should be considered regarding product availability? A: Both the 0MIB025.X and 1620-2-25A are classified as obsolete or discontinued. Procurement should prioritize current inventory levels and establish long-term component sourcing strategies.

Q: Does the voltage rating difference affect compatibility? A: The 1620-2-25A is rated for 14.5V DC, which exceeds the 12V requirement of the original design. This higher rating is compatible with 12V system operation.
