Substitute Part Grouping Explanation

Substitution eligibility for the 8345-C12A-S3M2-DB1B1C-10A is determined by strict equivalence across the following critical parameters:

• Current Rating: 10A (exact match required)
• Voltage Rating AC: 480V (exact match required)
• Voltage Rating DC: 80V (exact match required)
• Breaker Type: Magnetic (Hydraulic Delay) (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 2 (exact match required)
• Approval Agencies: CSA C22.2 No 235, GB 17701, IEC 60934, UL1077, UL489 (exact match required)
• Series: 8345 (same manufacturer series)

The identified substitute parts maintain all electrical and mechanical parameters identical to the main part while offering active product status and current availability.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 8345-B02A-V3M2-DB1B1C-10A and 8345-B22A-V3M2-DB1B1B-10A are direct parametric equivalents to the obsolete 8345-C12A-S3M2-DB1B1C-10A. Selection between these alternatives is based on the following factors:

RoHS Compliance: The substitute parts 8345-B02A-V3M2-DB1B1C-10A and 8345-B22A-V3M2-DB1B1B-10A are ROHS3 compliant, providing environmental compliance advantages over the obsolete part.

Inventory Availability: Both substitutes maintain adequate stock levels (652 and 729 units respectively) for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can 8345-B02A-V3M2-DB1B1C-10A and 8345-B22A-V3M2-DB1B1B-10A be used interchangeably with 8345-C12A-S3M2-DB1B1C-10A?

A: Yes. Both substitute parts maintain identical electrical ratings (10A, 480V AC, 80V DC), breaker type (Magnetic Hydraulic Delay), mounting configuration (Panel Mount Lever), pole count (2), and regulatory certifications. Direct substitution is supported without circuit modification.

Q: What is the difference between the two substitute parts?

A: The substitute parts differ only in packaging designation and internal part number coding. Electrical and mechanical specifications are identical. Selection depends on packaging requirements and internal procurement systems.

Q: Why is the original part classified as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. Active substitute parts with identical specifications are available to maintain system continuity and component availability.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 8345-B02A-V3M2-DB1B1C-10A and 8345-B22A-V3M2-DB1B1B-10A are ROHS3 compliant, meeting current environmental regulations.

Q: Do all parts maintain the same regulatory certifications?

A: Yes. The main part and both substitutes carry identical approval agency certifications: CSA C22.2 No 235, GB 17701, IEC 60934, UL1077, and UL489.
