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

Part Overview

The Littelfuse 0215.500HXP is a ceramic cartridge fuse rated for 500mA at 250VAC, housed in a 5mm x 20mm form factor. This component is classified as Active product status and requires a fuse holder for installation. Ceramic fuses of this specification are essential protective devices in electronic equipment where circuit protection against overcurrent conditions is required. Alternative equivalent parts may be necessary due to inventory availability, supply chain considerations, or specific application requirements within the defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Littelfuse 0215.500HXP is determined by strict equivalence across the following critical parameters:

• Current Rating: 500 mA (exact match required)
• Voltage Rating: 250 V AC (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: 1.5kA (exact match required)

Substitute parts are grouped into two categories:

Parametric Equivalents — Parts manufactured by Littelfuse (0215.500MXP, 0215.500TXP, 0285.500HXP) that maintain identical electrical and mechanical specifications within the Series 215 and 285 product lines.

Cross-Manufacturer Equivalents — Parts from alternative manufacturers (Bel Fuse Inc., Eaton Electronics Division, OptiFuse) that meet the same electrical performance and physical form factor requirements, with variations in secondary parameters such as melting I²t, DC cold resistance, and approval agency certifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, confirming ongoing manufacturer support and environmental regulatory adherence.

Littelfuse Series 215 and 285 parts (0215.500MXP, 0215.500TXP, 0285.500HXP) are direct parametric equivalents within the same manufacturer ecosystem, offering the highest compatibility assurance for applications currently using the 0215.500HXP.

Bel Fuse 5HT 500-R meets all critical electrical and mechanical parameters with approval agency certifications including CCC, CE, CSA, and cULus, suitable for applications requiring multi-regional compliance.

Eaton S505 Series (BK/S505-500-R, BK1/S505-500-R) provides equivalent electrical performance with comprehensive approval agency coverage including BSI, CCC/CQC, CSA, cURus, IMQ, SEMKO, and VDE, supporting global deployment requirements.

OptiFuse TCD-500MA delivers parametric equivalence with cURus and IEC 60127 approvals, appropriate for applications requiring IEC-based certification frameworks.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Littelfuse 0215.500HXP with any of the listed alternatives?

A: Yes, all listed parts are parametric or cross-manufacturer equivalents that maintain the same current rating (500mA), voltage rating (250VAC), package dimensions (5mm x 20mm), response time (Slow Blow), and breaking capacity (1.5kA). Physical and electrical compatibility is assured within these parameters.

Q: What is the difference between Littelfuse Series 215 and Series 285 fuses?

A: Both series maintain identical electrical ratings and physical dimensions. The primary differences are in secondary parameters such as melting I²t values and approval agency certifications. Series 215 parts carry CE, CSA, SEMKO, UL, and VDE approvals, while the 0285.500HXP does not list specific approval agencies.

Q: Are there approval agency differences I should consider?

A: Yes. The original Littelfuse 0215.500HXP carries CE, CSA, SEMKO, UL, and VDE approvals. Cross-manufacturer alternatives carry different approval combinations. Bel Fuse 5HT 500-R includes CCC, CE, CSA, and cULus. Eaton S505 series includes BSI, CCC/CQC, CSA, cURus, IMQ, SEMKO, and VDE. OptiFuse TCD-500MA includes cURus and IEC 60127. Select based on your application's regional compliance requirements.

Q: Do all substitute parts fit in the same fuse holder?

A: All substitute parts share the 5mm x 20mm package specification. Physical fit in standard 5x20mm fuse holders is assured. Verify your specific fuse holder design accommodates ceramic cartridge fuses.

Q: What is the significance of melting I²t values?

A: Melting I²t indicates the thermal energy required to melt the fuse element. The original 0215.500HXP specifies 0.42. Substitute parts show variations: Littelfuse 0215.500MXP and 0215.500TXP match at 0.42, while 0285.500HXP is 0.3, Bel Fuse 5HT 500-R is 0.46, and Eaton S505 series is 0.188. These variations reflect different fuse element designs but do not affect the 500mA current rating or 250VAC voltage rating.

Q: Can I use these fuses without a holder?

A: No. All listed parts, including the original 0215.500HXP, require a fuse holder for installation. These are cartridge-type fuses designed for use in standardized 5x20mm fuse holders.
