SCF4030-15-05 Equivalent & Substitute Parts

Part Overview

The SCF4030-15-05 is a 15A 36VDC triggerable fuse designed for board mount surface mount applications in battery protection circuits. Manufactured by Eaton - Electronics Division, this component is classified as Active product status with full cURus approval. The device operates across a temperature range of -20°C to 60°C and features a fast blow response characteristic with 12 ~ 21.5V triggerable functionality.

Substitute parts become necessary when primary component availability is limited, when supply chain constraints occur, or when design flexibility across approved alternatives is required for manufacturing optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCF4030-15-05 is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Current Rating: 15A (exact match required)
• Voltage Rating - DC: 36 VDC (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 50A (exact match required)

Critical Mechanical Parameters:

• Mounting Type: Surface Mount (exact match required)
• Package / Case: 1612 (4030 Metric) (exact match required)
• Size / Dimension: 0.157" L x 0.118" W x 0.035" H / 4.00mm x 3.00mm x 0.90mm (exact match required)
• Fuse Type: Board Mount (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• Approval Agency: cURus minimum requirement

Substitute parts must satisfy all critical parameters. Variations in triggerable voltage range, operating temperature range, DC cold resistance, and secondary certifications do not disqualify substitution when all critical parameters align.

Parameter Comparison

Engineering Selection Recommendations

SCF4030-15-05 (Eaton - Electronics Division):

• Primary selection for applications requiring the specified 12 ~ 21.5V triggerable voltage range
• Optimal for operating environments with extended low-temperature requirements (-20°C minimum)
• Lower DC cold resistance (0.001 Ohms) suitable for applications with stringent resistance specifications
• Active product status with established supply chain

ITV4030L2015NR (Littelfuse Inc. - POLYSWITCH® Series):

• Direct substitute when SCF4030-15-05 availability is constrained
• Suitable for applications tolerating the 14.4 ~ 23.5V triggerable voltage range
• Extended high-temperature capability (-10°C to 65°C) for elevated ambient environments
• Dual certification (cURus and TUV) provides additional regulatory flexibility
• Active product status with established supply chain

Both parts satisfy all critical electrical, mechanical, and compliance parameters. Selection between these alternatives is determined by application-specific requirements regarding triggerable voltage range, operating temperature extremes, and resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can ITV4030L2015NR replace SCF4030-15-05 in all applications?

A: ITV4030L2015NR is a direct substitute for SCF4030-15-05 when the application tolerates the triggerable voltage range of 14.4 ~ 23.5V. The SCF4030-15-05 features a triggerable range of 12 ~ 21.5V. Applications requiring triggering below 14.4V or above 21.5V must use SCF4030-15-05. All other critical parameters (current, voltage, package, mounting, response time) are identical.

Q: Are there any mechanical compatibility issues between these parts?

A: No. Both parts share identical package specifications (1612 / 4030 Metric) and physical dimensions (0.157" L x 0.118" W x 0.035" H / 4.00mm x 3.00mm x 0.90mm). Board layout and PCB footprints are directly compatible.

Q: What is the difference in DC cold resistance between these parts?

A: SCF4030-15-05 has a DC cold resistance of 0.001 Ohms, while ITV4030L2015NR has 0.003 Ohms. Applications with resistance-sensitive circuit designs should verify this parameter against design specifications.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) rating. SCF4030-15-05 carries cURus approval. ITV4030L2015NR carries both cURus and TUV approval, providing additional certification coverage.

Q: What is the operating temperature difference?

A: SCF4030-15-05 operates from -20°C to 60°C. ITV4030L2015NR operates from -10°C to 65°C. Applications requiring operation below -10°C must use SCF4030-15-05.

Q: Are these parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: What is the breaking capacity specification?

A: Both parts have a breaking capacity of 50A at rated voltage (36 VDC), meeting identical fault protection requirements.
