Littelfuse 0215.500H Ceramic Fuse 500mA 250VAC 5x20mm - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0215.500H is a 500mA ceramic cartridge fuse rated for 250V AC/DC operation in a 5x20mm form factor. This part is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs. The fuse requires a holder for installation and provides slow-blow response characteristics suitable for circuit protection applications. Direct replacements from active product lines are available from multiple manufacturers while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0215.500H is determined by strict equivalence across the following parameters:

• Current Rating: 500 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5kA (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed below meet these criteria. Variations in secondary parameters such as melting I²t, DC cold resistance, and approval agencies do not affect functional substitution but may influence selection based on compliance requirements or system design constraints.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are functionally equivalent to the 0215.500H based on core electrical and mechanical parameters. Selection among substitutes should be based on the following criteria:

For RoHS3 Compliance Requirements: The 0215.500HXP (Littelfuse), 0001.2501 (SCHURTER), BK/S505-500-R (Eaton), BK1/S505-500-R (Eaton), and S505-500-R (Eaton) all meet ROHS3 compliance. The original 0215.500H is RoHS non-compliant and should not be used in new designs subject to RoHS regulations.

For Extended DC Voltage Rating: The 0001.2501 (SCHURTER) provides a 300V DC rating in addition to the 250V AC specification, offering enhanced capability for DC circuit applications.

For Broadest Certification Coverage: The BK/S505-500-R and BK1/S505-500-R (Eaton) carry the most comprehensive approval agency certifications, including BSI, CCC/CQC, CSA, cULus, IMQ, SEMKO, and VDE, suitable for global market applications.

For Direct Littelfuse Continuity: The 0215.500HXP maintains the Littelfuse product line while offering active product status and improved compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the 0215.500H?

A: Yes. All listed substitute parts meet the core electrical and mechanical specifications: 500mA current rating, 250V AC voltage rating, slow-blow response, 5x20mm ceramic cartridge form factor, 1.5kA breaking capacity, and -55°C to 125°C operating temperature range. Physical installation in existing holders is identical.

Q: What is the difference between the Littelfuse 0215.500H and 0215.500HXP?

A: Both are 500mA 250V AC ceramic cartridge fuses in 5x20mm form factor. The primary differences are product status (0215.500H is obsolete; 0215.500HXP is active) and compliance certifications (0215.500HXP is ROHS3 compliant with expanded approval agencies including CE and VDE). The 0215.500HXP is the recommended Littelfuse replacement.

Q: Why does the SCHURTER 0001.2501 specify 300V DC while others do not?

A: The 0001.2501 is rated for both 250V AC and 300V DC operation. This extended DC rating does not affect AC circuit compatibility but provides additional capability for DC applications. Selection should be based on actual circuit voltage requirements.

Q: Are there differences in melting I²t values among the substitutes?

A: Yes. Melting I²t values vary (0.34 to 0.5 across the listed parts), reflecting differences in internal fuse element design. These variations do not affect substitution eligibility as all parts meet the 1.5kA breaking capacity requirement. The I²t parameter is secondary to the primary electrical ratings for substitution purposes.

Q: Which substitute offers the best global compliance coverage?

A: The Eaton BK/S505-500-R and BK1/S505-500-R carry certifications from BSI, CCC/CQC, CSA, cULus, IMQ, SEMKO, and VDE, providing the broadest international approval coverage for applications requiring multi-region compliance.

Q: Can I mix different substitute parts in the same system?

A: Yes. All substitute parts are electrically and mechanically equivalent and can be used interchangeably within the same circuit protection application. System design should account for any specific compliance or certification requirements applicable to the end application.
