FD-4030-12A-C1-C Equivalent & Substitute Parts

Part Overview

The FD-4030-12A-C1-C is a 12A/35VDC surface mount board fuse manufactured by Delta Electronics/Cyntec, designed for battery protection applications with fast-blow response characteristics and 3~4.5V triggerable features. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical performance across current rating, voltage rating, response time, and triggering specifications while accommodating the 1612 (4030 Metric) package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FD-4030-12A-C1-C is determined by the following critical parameters:

• Current Rating: Must be 12A
• Voltage Rating (DC): Must be ≥35 VDC (36 VDC acceptable)
• Response Time: Must be Fast Blow
• Triggerable Range: Must be 3 ~ 4.5V
• Package / Case: Must be 1612 (4030 Metric)
• Mounting Type: Must be Surface Mount
• Breaking Capacity @ Rated Voltage: Must be ≥50A
• RoHS Compliance: Must be ROHS3 Compliant

The SCF4030-12-01 manufactured by Eaton - Electronics Division meets all substitution criteria and is classified as an active product, providing long-term availability and supply chain stability.

Engineering Selection Recommendations

The SCF4030-12-01 is the qualified substitute for the obsolete FD-4030-12A-C1-C. Selection is based on:

• Product Status: SCF4030-12-01 is active, ensuring continued availability and manufacturing support
• Electrical Equivalence: Both parts maintain identical current rating (12A), response time (Fast Blow), triggerable range (3~4.5V), and breaking capacity (50A)
• Voltage Compatibility: SCF4030-12-01 rated at 36 VDC exceeds the original 35 VDC specification
• Package Compatibility: Both use 1612 (4030 Metric) surface mount package with identical footprint dimensions
• Regulatory Compliance: Both are ROHS3 compliant; SCF4030-12-01 carries cURus certification (UL/CSA recognized)
• Thermal Operating Range: SCF4030-12-01 extends lower temperature limit to -20°C, providing broader environmental coverage

Frequently Asked Questions (FAQ)

Q: Can SCF4030-12-01 be used as a direct replacement for FD-4030-12A-C1-C?

A: Yes. Both parts share identical current rating (12A), response time (Fast Blow), triggerable range (3~4.5V), package footprint (1612/4030 Metric), and breaking capacity (50A). The SCF4030-12-01 has a higher voltage rating (36 VDC vs. 35 VDC), which is acceptable for direct substitution.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (Delta/Cyntec vs. Eaton), product status (obsolete vs. active), operating temperature range (-10°C~65°C vs. -20°C~60°C), and regulatory certifications (TUV/UL vs. cURus). Electrical performance and package dimensions are equivalent.

Q: Are there any packaging differences?

A: The FD-4030-12A-C1-C packaging is not specified in available data. The SCF4030-12-01 is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement process.

Q: Does the operating temperature range difference affect substitution?

A: The SCF4030-12-01 operates from -20°C to 60°C, while the original operates from -10°C to 65°C. If your application requires operation above 60°C or below -20°C, verify thermal performance requirements before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both FD-4030-12A-C1-C and SCF4030-12-01 are ROHS3 compliant.
