Littelfuse 0218010.MXEP Equivalent & Substitute Parts

Part Overview

The Littelfuse 0218010.MXEP is a 10 A 250 V AC/DC slow-blow glass cartridge fuse with a 5mm x 20mm axial form factor. This fuse is designed for circuit protection in applications requiring controlled response characteristics and is currently in active production status. Equivalent and substitute parts are identified when component availability, supply chain considerations, or design flexibility require alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 0218010.MXEP are qualified based on the following critical parameters:

• Current Rating: 10 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm axial form factor (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

All identified substitute parts meet these core electrical and mechanical parameters, ensuring direct functional equivalence in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

All three fuses meet the core electrical and mechanical requirements for direct substitution. Selection should be based on the following factors:

Littelfuse 0218010.MXEP — Primary choice with full regulatory approvals (CE, CSA, K-MARK, PSE, UL, VDE) and higher breaking capacity (100 A). Suitable for applications requiring maximum certification coverage.

SCHURTER 0034.3127.PT — Functionally equivalent with ROHS3 compliance and 100 A breaking capacity. Dimensional tolerance on diameter (5.40mm vs. 5.80mm) remains within typical fuse holder specifications. Suitable where SCHURTER supply chain is preferred.

Bel Fuse 5STP 10-R — Functionally equivalent with CE, CSA, and cURus certifications. Breaking capacity is rated at 10 A (lower than primary part). Dimensional variations in both diameter and length are present. Selection should confirm compatibility with specific fuse holder mechanical tolerances and breaking capacity requirements.

Frequently Asked Questions (FAQ)

Q: Can these fuses be used interchangeably in the same circuit?

A: Yes, all three fuses share identical electrical ratings (10 A, 250 V AC, slow-blow response). Physical dimensions vary slightly; confirm fuse holder mechanical tolerances before substitution.

Q: What is the significance of breaking capacity differences?

A: Breaking capacity indicates the maximum fault current the fuse can safely interrupt. The Littelfuse and SCHURTER parts are rated at 100 A, while the Bel Fuse is rated at 10 A. For applications with fault currents exceeding 10 A, the Littelfuse or SCHURTER parts are required.

Q: Are all parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What do the dimensional differences mean for installation?

A: Fuse cartridges are installed in standardized holders. Minor diameter and length variations (within the 5mm x 20mm family) are typically accommodated by holder design. Verify specific holder specifications before substitution, particularly for the Bel Fuse 5STP 10-R, which has the greatest dimensional variance.

Q: Which part has the best regulatory coverage?

A: The Littelfuse 0218010.MXEP carries the broadest approval agency certifications (CE, CSA, K-MARK, PSE, UL, VDE). The Bel Fuse 5STP 10-R carries CE, CSA, and cURus certifications. The SCHURTER 0034.3127.PT does not list specific approval agencies in the provided data.

Q: What is the melting I²t parameter?

A: Melting I²t is a thermal characteristic indicating the energy required to melt the fuse element. Values provided (Littelfuse: 568, SCHURTER: 520, Bel Fuse: 439) reflect design differences but do not affect substitution compatibility for the specified 10 A slow-blow application.
