FCD061500TP Equivalent & Substitute Parts

Part Overview

The FCD061500TP is a 5A surface mount board mount fuse manufactured by Littelfuse Inc., rated for 24V DC operation in a 0603 (1608 Metric) package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The fast-blow response characteristic and compact surface mount form factor position this fuse for protection in low-voltage DC circuits requiring rapid fault response.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCD061500TP is determined by the following critical parameters:

Current Rating: The substitute must maintain 5 A current rating to ensure proper circuit protection without nuisance trips or inadequate fault response.

Package / Case: The 0603 (1608 Metric) surface mount package is mandatory for PCB compatibility and assembly process alignment.

Mounting Type: Surface mount technology is required to match the original design footprint and reflow soldering process.

Fuse Type: Board mount configuration (cartridge style excluded) ensures mechanical and electrical compatibility with the circuit board interface.

Response Time: Fast-blow characteristic must be preserved to maintain the intended fault response profile.

Voltage Rating: The substitute voltage rating must equal or exceed the original 24V DC specification. A higher voltage rating (32V DC) is acceptable as it provides enhanced margin and broader application compatibility while maintaining the same current and package specifications.

Breaking Capacity: The substitute must maintain or exceed the 35 A breaking capacity at rated voltage to ensure safe fault interruption.

The substitute part 0467005.NR meets all these criteria while offering improved electrical characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 0467005.NR is the designated manufacturer-recommended substitute for the obsolete FCD061500TP. Both components are manufactured by Littelfuse Inc. and share identical current ratings, package specifications, and fast-blow response characteristics.

The substitute provides enhanced voltage margin with a 32V DC rating compared to the original 24V DC specification, making it suitable for applications operating at or below 24V DC. The substitute also carries active product status, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and MSL Level 1 classification, supporting standard PCB assembly and storage practices. The substitute carries broader approval agency recognition (CSA and UL) compared to the original (cULus), providing additional certification coverage for regulated applications.

The substitute exhibits lower DC cold resistance (0.0089 Ohms versus 0.014 Ohms), resulting in reduced resistive heating during normal operation. The higher melting I²t value (0.9 versus 0.58) reflects improved thermal characteristics while maintaining the same 5A current rating and fast-blow response profile.

Frequently Asked Questions (FAQ)

Q: Can the 0467005.NR be used as a direct replacement for the FCD061500TP?

A: Yes. Both components share identical current ratings (5A), package specifications (0603 / 1608 Metric), mounting type (surface mount), and response characteristics (fast-blow). The substitute's higher voltage rating (32V DC) is compatible with circuits designed for 24V DC operation.

Q: What is the significance of the voltage rating difference between the two parts?

A: The original FCD061500TP is rated for 24V DC, while the substitute 0467005.NR is rated for 32V DC. A higher voltage rating provides additional safety margin and does not compromise protection in lower-voltage applications. The substitute is suitable for any circuit operating at or below 24V DC.

Q: Are there any thermal operating range considerations?

A: The original part operates from -55°C to 125°C, while the substitute operates from -55°C to 90°C. For applications requiring operation above 90°C, the original specification must be verified. For standard industrial and commercial applications within the -55°C to 90°C range, both parts are equivalent.

Q: How do the electrical characteristics compare?

A: The substitute exhibits lower DC cold resistance (0.0089 Ohms versus 0.014 Ohms), reducing resistive heating. The higher melting I²t value (0.9 versus 0.58) reflects improved thermal performance. Both maintain identical breaking capacity (35A) and fast-blow response, ensuring equivalent circuit protection.

Q: What are the packaging and supply differences?

A: The FCD061500TP is obsolete with limited remaining inventory (692 pcs). The 0467005.NR is active with substantial inventory availability (15,300 pcs) in Tape & Reel packaging, supporting high-volume production requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the FCD061500TP and 0467005.NR are ROHS3 compliant and carry MSL Level 1 classification, supporting standard PCB assembly and storage practices without special handling requirements.
