FCD060500TP Equivalent & Substitute Parts

Part Overview

The FCD060500TP is a 500 mA, 32 V DC surface mount board fuse in 0603 (1608 Metric) package manufactured by Littelfuse Inc. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The fast-blow response characteristic and compact surface mount form factor make this fuse suitable for circuit protection in compact electronic assemblies operating at low voltage levels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCD060500TP is determined by the following critical parameters:

• Current Rating: 500 mA (exact match required)
• Voltage Rating - DC: Minimum 32 V (equal or higher acceptable)
• Response Time: Fast Blow (must match)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)

The substitute parts listed below meet these core electrical and mechanical compatibility criteria. Voltage ratings may exceed the original specification, which is acceptable for circuit protection applications where higher voltage tolerance does not compromise circuit function.

Parameter Comparison

Engineering Selection Recommendations

0467.500NR is the manufacturer-recommended substitute for FCD060500TP. This part maintains identical DC voltage rating (32 V) and current rating (500 mA), ensuring direct functional equivalence. Both parts share the same package, mounting type, and response characteristic. The 0467.500NR carries active product status with CSA and UL approvals, supporting long-term design continuity. The lower DC cold resistance (0.187 Ω vs. 0.28 Ω) and reduced melting I²t value indicate faster response characteristics, which is acceptable for circuit protection. The operating temperature range is narrower (-55°C ~ 90°C), which must be verified against application requirements.

0438.500WR is an alternative substitute that meets all core compatibility criteria. This part offers higher DC voltage rating (63 V) and extended operating temperature range (-55°C ~ 150°C), providing greater design margin for applications with elevated temperature exposure or higher voltage transients. The higher melting I²t (0.01) and DC cold resistance (0.829 Ω) indicate slightly slower response compared to the original specification. This part is suitable for applications where the additional voltage and temperature headroom does not conflict with circuit design intent.

Both substitute parts are ROHS3 compliant and carry active product status with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can 0467.500NR directly replace FCD060500TP in existing designs?

A: Yes. The 0467.500NR matches the critical electrical parameters (500 mA, 32 V DC) and physical package (0603 surface mount). It is the manufacturer-recommended substitute. Verify that the narrower operating temperature range (-55°C ~ 90°C) is acceptable for your application environment.

Q: What is the difference between 0467.500NR and 0438.500WR?

A: Both parts are functionally compatible substitutes. The 0467.500NR maintains the original 32 V DC rating with faster response characteristics. The 0438.500WR offers higher voltage rating (63 V DC) and extended temperature range (-55°C ~ 150°C) at the cost of slightly slower response. Select based on application voltage and temperature requirements.

Q: Is the higher breaking capacity (50 A vs. 35 A) in the substitute parts a concern?

A: No. Higher breaking capacity indicates improved fault tolerance and does not affect normal circuit operation. This is a beneficial characteristic for circuit protection.

Q: Are all three parts ROHS3 compliant?

A: Yes. FCD060500TP, 0467.500NR, and 0438.500WR are all ROHS3 compliant, meeting environmental and regulatory requirements.

Q: What certifications do the substitute parts carry?

A: Both 0467.500NR and 0438.500WR carry CSA and UL approvals. The original FCD060500TP carries cULus approval. All certifications are recognized for circuit protection applications.

Q: Can I use 0438.500WR in applications originally designed for FCD060500TP?

A: Yes, provided your circuit design does not depend on the specific response characteristics of the original fuse. The higher voltage rating and temperature range make this part suitable for most applications. Verify that the increased melting I²t value does not conflict with circuit protection strategy.
