Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCF4030-12-01 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating: 12A
• Voltage Rating (DC): 36 VDC
• Response Time: Fast Blow
• Triggerable Threshold: 3 ~ 4.5V
• Breaking Capacity @ Rated Voltage: 50A
• Package / Case: 1612 (4030 Metric)
• Physical Dimensions: 0.157" L x 0.118" W x 0.035" H (4.00mm x 3.00mm x 0.90mm)
• Mounting Type: Surface Mount
• Fuse Type: Board Mount
• Application: Battery Protection

The ITV4030L0412NR manufactured by Littelfuse Inc. meets all critical electrical and mechanical specifications required for direct substitution. Both components share identical current ratings, voltage ratings, response characteristics, triggerable thresholds, breaking capacity, package designation, and physical dimensions. Both are surface mount board mount fuses designed for battery protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SCF4030-12-01 and ITV4030L0412NR are active production components with full regulatory compliance. The SCF4030-12-01 carries cURus approval, while the ITV4030L0412NR carries both cURus and TUV approvals, providing additional certification coverage. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no moisture-related handling restrictions.

The ITV4030L0412NR demonstrates a lower DC cold resistance (0.000018 Ohms versus 0.001 Ohms), which may provide marginal performance advantages in low-resistance circuit paths. The operating temperature range of the ITV4030L0412NR (-10°C ~ 65°C) is slightly narrower than the SCF4030-12-01 (-20°C ~ 60°C) at the lower temperature extreme but extends 5°C higher at the upper limit. Selection between these components should be based on specific application temperature requirements and certification mandates.

Frequently Asked Questions (FAQ)

Q: Can the ITV4030L0412NR directly replace the SCF4030-12-01 in existing circuit designs?

A: Yes. Both components share identical electrical ratings (12A, 36VDC), response characteristics (fast-blow), triggerable thresholds (3 ~ 4.5V), breaking capacity (50A), and physical dimensions (1612 / 4030 Metric package). Both are surface mount board mount fuses designed for battery protection applications.

Q: Are there differences in operating temperature ranges between these parts?

A: The SCF4030-12-01 operates from -20°C to 60°C, while the ITV4030L0412NR operates from -10°C to 65°C. Applications requiring operation below -10°C must use the SCF4030-12-01. Applications requiring operation above 60°C must use the ITV4030L0412NR.

Q: What is the significance of the DC cold resistance difference?

A: The ITV4030L0412NR exhibits lower DC cold resistance (0.000018 Ohms) compared to the SCF4030-12-01 (0.001 Ohms). This difference is negligible for most battery protection applications but may be relevant in circuits with extremely low impedance paths where minimal voltage drop is critical.

Q: Do both parts carry the same regulatory approvals?

A: Both parts carry cURus approval. The ITV4030L0412NR additionally carries TUV approval, providing broader regulatory coverage for applications requiring multiple certification standards.

Q: Are the physical dimensions identical?

A: Yes. Both components are packaged in the 1612 (4030 Metric) case with dimensions of 0.157" L x 0.118" W x 0.035" H (4.00mm x 3.00mm x 0.90mm). They are mechanically interchangeable on PCB layouts designed for either part.

Q: What is the moisture sensitivity level for both parts?

A: Both components carry MSL 1 (Unlimited) ratings, indicating no moisture-related handling or storage restrictions. Standard component handling practices apply.
