Littelfuse 0215005.H Ceramic Fuse 5A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0215005.H is a 5A 250VAC ceramic cartridge fuse with 5x20mm dimensions, designed for applications requiring slow-blow response characteristics. This part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility. Substitute parts must preserve the 5A current rating, 250V AC voltage specification, 5x20mm form factor, and slow-blow response time to ensure proper circuit protection without modification to existing fuse holders.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Current Rating: 5 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5kA (exact match required)

All identified substitute parts meet these criteria. Variations in secondary parameters such as melting I²t, DC cold resistance, and approval agency certifications do not affect functional substitutability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the 0215005.H. Selection among active alternatives should prioritize product status and regulatory compliance:

Littelfuse 0215005.HXP is the direct manufacturer equivalent from Littelfuse, offering ROHS3 compliance and active product status. This part represents the primary substitution path for existing 0215005.H applications.

SCHURTER 0001.2511 provides an alternative from a different manufacturer with ROHS3 compliance and active status. This part includes DC voltage rating specification (150V DC) not present in the main part specification.

Eaton S505 Series (BK/S505-5-R, BK1/S505-5-R, S505-5-R) represents manufacturer-recommended alternatives with comprehensive international approval certifications including BSI, CCC/CQC, CSA, cULus, IMQ, KC, PSE/JET, SEMKO, and VDE. All three variants maintain active product status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can 0215005.HXP be used as a direct replacement for 0215005.H?

A: Yes. Both parts share identical electrical ratings (5A, 250VAC), response time (slow blow), and mechanical dimensions (5x20mm). The primary difference is product status: 0215005.H is obsolete while 0215005.HXP is active. 0215005.HXP also provides ROHS3 compliance.

Q: What is the difference between the Littelfuse and Eaton substitute options?

A: All substitute parts meet the same electrical and mechanical requirements. Littelfuse 0215005.HXP maintains the original manufacturer lineage. Eaton S505 series parts offer broader international certification coverage. Selection depends on supply chain preference and certification requirements for the application.

Q: Does the SCHURTER 0001.2511 differ functionally from other substitutes?

A: The SCHURTER part includes a specified DC voltage rating (150V DC) not documented in other parts. All parts maintain identical AC ratings, current, response time, and mechanical form factor. The additional DC specification does not affect AC-only applications.

Q: Are all substitute parts compatible with existing 5x20mm fuse holders?

A: Yes. All substitute parts maintain the 5x20mm package specification and cartridge ceramic fuse type, ensuring mechanical compatibility with existing fuse holders designed for the 0215005.H.

Q: What compliance certifications should I consider for new designs?

A: All active substitute parts carry ROHS3 compliance. The Eaton S505 series provides the broadest international certification coverage including BSI, CCC/CQC, CSA, cULus, IMQ, KC, PSE/JET, SEMKO, and VDE. Littelfuse 0215005.HXP carries CSA, CE, CCC, KC, PSE, SEMKO, UL, and VDE certifications.
