Littelfuse 0217015.H Glass Cartridge Fuse 15A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0217015.H is a 15A 250VAC fast-blow glass cartridge fuse in 5x20mm form factor, designed for circuits requiring holder-mounted fuse protection. This part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for direct circuit substitution.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (15A), voltage rating (250VAC), fuse type (cartridge glass), response time (fast blow), physical dimensions (5x20mm), and mounting configuration (holder-required). All identified substitutes maintain these core electrical and mechanical specifications.

The substitute parts are grouped into two categories based on product status and compliance certifications:

Active Littelfuse Variants (0217015.HXP, 0217015.MXBP, 0217015.MXP, 0217015.TXP): These parts are manufactured by Littelfuse within the 217 series and are currently in active production status. All four variants are RoHS3 compliant and carry expanded approval certifications (CE, PSE, VDE).

Active Cross-Manufacturer Alternative (FSD-15A): OptiFuse FSD-15A provides electrical equivalence with identical current, voltage, and response characteristics. This part carries IEC 60127 certification and is RoHS3 compliant.

Engineering Selection Recommendations

For applications currently using the obsolete 0217015.H, the Littelfuse variants (0217015.HXP, 0217015.MXBP, 0217015.MXP, 0217015.TXP) are preferred substitutes. These parts maintain identical electrical specifications while offering active production status, RoHS3 compliance, and expanded certification coverage (CE, PSE, VDE). All four Littelfuse variants are electrically and mechanically interchangeable.

The OptiFuse FSD-15A provides an alternative cross-manufacturer option with equivalent electrical performance and IEC 60127 certification. Selection between Littelfuse and OptiFuse variants depends on existing supply chain qualification and certification requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 0217015.H be directly replaced with any of the listed substitutes? A: Yes. All substitute parts maintain identical current rating (15A), voltage rating (250VAC), fuse type (cartridge glass), response time (fast blow), physical dimensions (5x20mm), and mounting configuration (holder-required). Direct substitution is electrically and mechanically valid.

Q: What is the difference between the four Littelfuse variants? A: The 0217015.HXP, 0217015.MXBP, 0217015.MXP, and 0217015.TXP are electrically identical. Differences exist only in packaging format and internal manufacturing specifications. All are active production parts with RoHS3 compliance and CE, PSE, VDE certifications.

Q: Is the OptiFuse FSD-15A a suitable alternative? A: Yes. The FSD-15A meets all electrical and mechanical equivalence criteria. It carries IEC 60127 certification and RoHS3 compliance. Selection depends on application-specific certification requirements and supply chain considerations.

Q: Does the 0217015.H require a specific holder type? A: Yes. The 0217015.H is a cartridge fuse requiring a holder for installation. All substitute parts maintain this requirement. Ensure the existing holder is compatible with the 5x20mm form factor.

Q: Are there compliance differences between the main part and substitutes? A: Yes. The 0217015.H is RoHS non-compliant. All substitute parts are RoHS3 compliant. The Littelfuse variants carry expanded certifications (CE, PSE, VDE) compared to the original part (CE, PSE).
