5HFP 500 Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The 5HFP 500 is a 500 mA, 250 V AC/DC ceramic cartridge fuse with fast-blow response characteristics, designed for 5mm x 20mm through-hole mounting applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs. The fuse provides 1.5 kA breaking capacity and operates across -55°C to 125°C temperature range with multiple international approvals including CCC, CE, CSA, and UL.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5HFP 500 is determined by the following critical parameters: current rating (500 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), package dimensions (5mm x 20mm), response time (fast blow), and breaking capacity (1.5 kA). Parts meeting these specifications are classified as parametric equivalents. The 5HFP 500-R from Bel Fuse Inc. is a direct parametric equivalent with identical electrical characteristics and through-hole mounting. The SCHURTER 0001.1001.PT and Littelfuse 0216.500MXEP are also parametric equivalents meeting all core electrical and mechanical requirements.

The 5HF 630-R represents a higher current rating variant (630 mA) and is listed as a direct manufacturer substitute, though it requires a holder rather than through-hole mounting. The SCHURTER 0001.1011.PT (5 A rating) differs significantly in current rating and is not suitable as a direct substitute for 500 mA applications.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the obsolete 5HFP 500, the 5HFP 500-R from Bel Fuse Inc. is the primary choice, offering identical electrical specifications, through-hole mounting compatibility, and active product status with ROHS3 compliance. This part maintains full backward compatibility with existing PCB designs.

The SCHURTER 0001.1001.PT and Littelfuse 0216.500MXEP are functionally equivalent alternatives meeting all core electrical and mechanical parameters. Both are active products with ROHS3 compliance and appropriate international certifications (cURus for SCHURTER; CCC, CE, CSA, SEMKO, UR, VDE for Littelfuse). Selection between these alternatives depends on supply chain availability and specific certification requirements for the application.

The 5HF 630-R is not recommended as a direct substitute due to its higher current rating (630 mA) and requirement for a separate holder rather than through-hole mounting, which would necessitate PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the 5HFP 500-R be used as a direct replacement for the obsolete 5HFP 500?

A: Yes. The 5HFP 500-R is a parametric equivalent with identical current rating (500 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), package dimensions (5mm x 20mm axial), response time (fast blow), and breaking capacity (1.5 kA). Both use through-hole mounting, ensuring PCB compatibility without modification.

Q: What is the difference between the 5HFP 500-R and the SCHURTER 0001.1001.PT?

A: Both are 500 mA, 250 V AC ceramic cartridge fuses with 5mm x 20mm through-hole mounting and fast-blow response. Differences include manufacturer, melting I²t values (0.16 for Bel Fuse vs. 0.098 for SCHURTER), physical dimensions (5.50mm x 21.00mm vs. 5.40mm x 22.50mm), and DC cold resistance (0.34 Ohms vs. not specified). These variations are within acceptable tolerances for equivalent substitution.

Q: Why is the 5HF 630-R listed as a substitute if it has a different current rating?

A: The 5HF 630-R is listed as a direct manufacturer substitute by Bel Fuse Inc., indicating it may serve specific application requirements. However, the higher 630 mA current rating makes it unsuitable for circuits designed for 500 mA protection. Additionally, it requires a separate holder rather than through-hole mounting, necessitating PCB redesign.

Q: Are all substitute parts RoHS compliant?

A: The 5HFP 500 is RoHS non-compliant. All active substitute parts (5HFP 500-R, 0001.1001.PT, 0216.500MXEP, and 5HF 630-R) are ROHS3 compliant, meeting current environmental regulations.

Q: What certifications should I verify for my specific application?

A: The 5HFP 500 carries CCC, CE, CSA, and UL approvals. The 5HFP 500-R maintains CCC, CE, CSA, and cURus certifications. SCHURTER 0001.1001.PT holds cURus approval, while Littelfuse 0216.500MXEP carries CCC, CE, CSA, SEMKO, UR, and VDE certifications. Verify that substitute part certifications align with your application's regulatory requirements.
