Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCF9550-30-14 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Current Rating: 30A (exact match required)
• Voltage Rating (DC): 62 VDC (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 80A (exact match required)

Mechanical Compatibility Requirements:

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

Environmental & Compliance Requirements:

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

The ITV9550L5030MR meets all critical electrical and mechanical parameters while maintaining full compliance with environmental standards. Dimensional variations and triggerable voltage range differences remain within acceptable substitution tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

Primary Component: SCF9550-30-14 (Eaton - Electronics Division)

The SCF9550-30-14 is the specified component for this application. It carries Active product status with cURus certification and is available in Cut Tape packaging with 1074 pieces in current inventory.

Substitute Component: ITV9550L5030MR (Littelfuse Inc.)

The ITV9550L5030MR is a qualified substitute that meets all critical electrical and mechanical parameters. This component carries Active product status with dual certifications (cURus and TUV) and is available in Tape & Reel packaging with 2133 pieces in current inventory.

Selection Basis:

Both components satisfy the mandatory requirements for 30A, 62 VDC board mount surface mount fuse applications with fast blow response and 80A breaking capacity. The ITV9550L5030MR provides extended operating temperature range (-10°C to 65°C versus -20°C to 60°C) and additional TUV certification. The substitute component is suitable for direct replacement in battery protection circuits where the SCF9550-30-14 is specified, provided that packaging format (Tape & Reel versus Cut Tape) is compatible with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the ITV9550L5030MR be used as a direct replacement for the SCF9550-30-14?

A: Yes. Both components share identical electrical ratings (30A, 62 VDC, fast blow, 80A breaking capacity), fuse type (board mount), mounting type (surface mount), package classification (nonstandard SMD), and compliance status (ROHS3 compliant, MSL 1). The substitute meets all critical substitution parameters.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Manufacturer (Eaton versus Littelfuse); (2) Packaging format (Cut Tape versus Tape & Reel); (3) Operating temperature range (SCF9550-30-14: -20°C to 60°C; ITV9550L5030MR: -10°C to 65°C); (4) DC cold resistance (0.001 Ohms versus 0.0025 Ohms); (5) Triggerable voltage range (28-62V versus 39.6-62V); (6) Certifications (cURus only versus cURus and TUV).

Q: Are there packaging considerations when substituting these parts?

A: Yes. The SCF9550-30-14 is supplied in Cut Tape (CT) packaging, while the ITV9550L5030MR is supplied in Tape & Reel (TR) packaging. Assembly equipment compatibility with the respective packaging formats must be confirmed before substitution.

Q: Does the ITV9550L5030MR have better temperature performance?

A: The ITV9550L5030MR operates across a wider temperature range (-10°C to 65°C) compared to the SCF9550-30-14 (-20°C to 60°C). Selection between these components should be based on the specific operating temperature requirements of the application.

Q: What is the significance of the different triggerable voltage ranges?

A: The SCF9550-30-14 triggers between 28-62V, while the ITV9550L5030MR triggers between 39.6-62V. Both components are suitable for battery protection applications within their respective triggerable ranges. Application voltage requirements determine which component is appropriate.

Q: Are both components RoHS compliant?

A: Yes. Both the SCF9550-30-14 and ITV9550L5030MR are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), making them suitable for applications with RoHS compliance requirements.
