Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCF5432-30-07 is determined by equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 30A (exact match required)
• Voltage Rating: 62 VDC (exact match required)
• Triggerable Range: 23–31.5V (exact match required)
• Breaking Capacity: 80A (exact match required)
• Response Time: Fast Blow (exact match required)

Mechanical Parameters:

• Mounting Type: Surface Mount (exact match required)
• Fuse Type: Board Mount (exact match required)
• Package / Case: Nonstandard SMD (compatible form factor)

Compliance Parameters:

• RoHS3 Compliance (required for substitution)
• Moisture Sensitivity Level 1 (required for substitution)

The ITV5432L3030WR manufactured by Littelfuse Inc. meets all critical electrical and mechanical parameters and is therefore qualified as a direct substitute for the SCF5432-30-07 in battery protection applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: SCF5432-30-07 (Eaton - Electronics Division)

The SCF5432-30-07 is the original specification component. It carries cURus approval and is ROHS3 compliant. Current inventory status shows 1295 pieces available. This part is recommended for applications where Eaton component qualification is a requirement or where existing supply chain relationships are established.

Substitute Part: ITV5432L3030WR (Littelfuse Inc.)

The ITV5432L3030WR is a qualified direct substitute that meets all critical electrical and mechanical parameters. This component carries dual approval (cURus and TUV) and is ROHS3 compliant with REACH Unaffected status. Current inventory shows 3726 pieces available. This part is suitable for direct replacement in battery protection circuits where the SCF5432-30-07 is specified, provided that dual certification and extended temperature range capability (−10°C to +65°C versus −20°C to +60°C) are acceptable for the application.

Both parts are active products with established supply availability. Selection between them should be based on procurement preference, supply chain considerations, and any manufacturer-specific qualification requirements in the end application.

Frequently Asked Questions (FAQ)

Q: Can the ITV5432L3030WR be used as a direct replacement for the SCF5432-30-07?

A: Yes. The ITV5432L3030WR meets all critical electrical parameters (30A, 62 VDC, 23–31.5V triggerable range, 80A breaking capacity, fast blow response) and mechanical parameters (surface mount, board mount, nonstandard SMD package). Both components are ROHS3 compliant with MSL 1 rating.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Eaton versus Littelfuse), approval agencies (cURus only versus cURus and TUV), operating temperature range (−20°C to +60°C versus −10°C to +65°C), DC cold resistance (0.0005 Ohms versus 0.0025 Ohms), and physical height (0.053" versus 0.071"). All electrical performance parameters are identical.

Q: Are there any dimensional compatibility concerns?

A: Both parts use nonstandard SMD packaging with identical length (0.213" / 5.40mm) and width (0.126" / 3.20mm). The ITV5432L3030WR is 0.018" (0.45mm) taller than the SCF5432-30-07. PCB layout and clearance requirements should be verified for the specific application.

Q: Which part should be selected for new designs?

A: Selection depends on design requirements and supply chain strategy. The ITV5432L3030WR offers dual certification (cURus and TUV) and extended temperature range capability. The SCF5432-30-07 is appropriate where Eaton qualification is specified. Both are active products with adequate inventory.

Q: Are these parts interchangeable in existing assemblies?

A: Yes, provided that the physical height difference (0.018") does not create clearance issues on the PCB and that the application does not require the lower operating temperature limit of −20°C. Electrical performance and triggering characteristics are equivalent.

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

A: The SCF5432-30-07 has lower DC cold resistance (0.0005 Ohms versus 0.0025 Ohms). This difference is within acceptable tolerance for battery protection applications and does not affect functional substitution. Both values are suitable for the specified 30A current rating.
