FCD061400TP Equivalent & Substitute Parts

Part Overview

The FCD061400TP is a surface mount board mount fuse manufactured by Littelfuse Inc., rated for 4A at 24VDC with fast blow response characteristics. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The 0603 (1608 Metric) package format and specific electrical ratings define the scope for compatible alternatives.

Substitute Part Grouping Explanation

Substitution of the FCD061400TP is determined by the following critical parameters:

Current Rating: Must be 4 A to maintain circuit protection characteristics
Package Format: Must be 0603 (1608 Metric) surface mount for PCB compatibility
Fuse Type: Must be board mount (cartridge style excluded) for identical mounting methodology
Response Time: Must be fast blow to preserve protection response profile
Voltage Rating: Must support minimum 24 VDC operation; higher voltage ratings are acceptable as they provide broader application compatibility

The substitute part 0467004.NR meets all substitution criteria while offering enhanced voltage ratings (32 VAC / 32 VDC) and active product status, making it suitable for direct replacement in applications requiring the FCD061400TP.

Engineering Selection Recommendations

The 0467004.NR is the direct substitute for the obsolete FCD061400TP. Both components are manufactured by Littelfuse Inc. and share identical current ratings, package formats, fuse types, and response characteristics. The substitute part offers the following advantages:

Active Product Status: 0467004.NR is in active production with 35,300 units in stock, ensuring long-term availability compared to the obsolete FCD061400TP
Enhanced Voltage Rating: The 32 VDC rating exceeds the 24 VDC requirement, providing compatibility with a broader range of circuit designs
Expanded Certifications: CSA and UL approvals provide additional regulatory coverage beyond the cULus certification of the original part
Lower DC Cold Resistance: The 0.00118 Ohms resistance of the substitute reduces voltage drop compared to the 0.019 Ohms of the original part

The narrower operating temperature range (-55°C to 90°C versus -55°C to 125°C) of the substitute should be evaluated for applications requiring operation above 90°C.

Frequently Asked Questions (FAQ)

Q: Can 0467004.NR be used as a direct replacement for FCD061400TP in existing designs?

A: Yes. Both parts share identical current ratings (4 A), package formats (0603 / 1608 Metric), fuse types (board mount surface mount), and response times (fast blow). The substitute's higher voltage rating (32 VDC) is compatible with circuits designed for 24 VDC operation.

Q: What is the primary reason for substitution?

A: The FCD061400TP is obsolete. The 0467004.NR is the active equivalent from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there any electrical differences that affect circuit performance?

A: The substitute has lower DC cold resistance (0.00118 Ohms versus 0.019 Ohms), resulting in reduced voltage drop across the fuse element. This is a beneficial characteristic that does not compromise protection function.

Q: Does the operating temperature range difference impact suitability?

A: The substitute operates from -55°C to 90°C, compared to the original -55°C to 125°C. Applications requiring operation above 90°C must be evaluated separately. For standard industrial and commercial applications within the -55°C to 90°C range, the substitute is fully suitable.

Q: Are certifications equivalent between the two parts?

A: The substitute carries CSA and UL certifications, providing broader regulatory coverage than the original part's cULus certification. Both certifications are recognized for board mount fuse applications.

Q: Is the 0603 package format identical between both parts?

A: Yes. Both parts use the 0603 (1608 Metric) surface mount package format with identical PCB footprints and reflow soldering compatibility.
