Key Parameters

Substitute Part Grouping Explanation

Substitution of the FC-5432-15A-C5-C is determined by strict equivalence across the following critical parameters:

• Current Rating: 15A (exact match required)
• Voltage Rating: 35 VDC minimum (36 VDC acceptable as higher rating)
• Response Time: Fast Blow (functional requirement for battery protection)
• Mounting Type: Surface Mount (PCB integration requirement)
• Fuse Type: Board Mount (application-specific requirement)
• Package / Case: Nonstandard SMD (physical footprint compatibility)
• Triggerable Range: 14.4 ~ 24.6V (operational specification)
• Breaking Capacity: 50A (safety specification)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The SCF5432-15-05 manufactured by Eaton - Electronics Division meets all substitution criteria within allowable tolerances.

Parameter Comparison

Engineering Selection Recommendations

The SCF5432-15-05 is a direct functional equivalent for the obsolete FC-5432-15A-C5-C based on electrical and mechanical parameter alignment. Selection of this substitute is supported by:

• Product Status: The SCF5432-15-05 is actively manufactured by Eaton - Electronics Division, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain ROHS3 compliance, meeting environmental and hazardous substance restrictions.
• Electrical Equivalence: Current rating (15A), voltage rating (36 VDC exceeds 35 VDC requirement), response time (Fast Blow), and breaking capacity (50A) are identical.
• Physical Compatibility: Nonstandard SMD package and footprint dimensions are equivalent, with a minor height variance of 0.20mm (1.15mm to 1.35mm) that does not affect PCB assembly compatibility.
• Functional Specification: Triggerable range (14.4 ~ 24.6V) and battery protection application alignment are maintained.
• Certification Difference: The substitute carries cURus certification rather than TUV/UL. Design validation should confirm cURus certification acceptability for the target application and regional requirements.

Frequently Asked Questions (FAQ)

Q: Can the SCF5432-15-05 be used as a direct replacement for the FC-5432-15A-C5-C?

A: Yes. The SCF5432-15-05 meets all critical electrical and mechanical parameters required for substitution, including current rating (15A), voltage rating (36 VDC), response time (Fast Blow), mounting type (Surface Mount), and package compatibility (Nonstandard SMD). The substitute is actively manufactured, addressing the obsolescence of the original part.

Q: What is the significance of the voltage rating difference (35 VDC vs 36 VDC)?

A: A higher voltage rating (36 VDC) is acceptable for substitution purposes. The substitute part maintains a safety margin and does not compromise circuit protection. Both parts operate within the same triggerable range (14.4 ~ 24.6V).

Q: Does the height difference (1.15mm vs 1.35mm) affect PCB assembly?

A: The height variance of 0.20mm is within typical PCB assembly tolerances for surface mount components and does not affect reflow soldering, component placement, or clearance requirements for standard board designs.

Q: Are the certifications equivalent between the two parts?

A: The FC-5432-15A-C5-C carries TUV and UL certifications, while the SCF5432-15-05 carries cURus certification. Both certifications are recognized for electrical safety. Application-specific requirements and regional compliance standards should be evaluated to confirm cURus certification acceptability.

Q: What is the operating temperature range difference?

A: The FC-5432-15A-C5-C operates from -10°C to 65°C, while the SCF5432-15-05 operates from -20°C to 60°C. The ranges overlap significantly. Design operating conditions should be evaluated to confirm the SCF5432-15-05 temperature range is suitable for the intended application.

Q: Is the SCF5432-15-05 available in the same packaging format?

A: The SCF5432-15-05 is supplied in Tape & Reel (TR) packaging, while the original part packaging is not specified. Tape & Reel packaging is standard for surface mount component distribution and is compatible with automated assembly processes.
