Littelfuse 0218010.MXE Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 0218010.MXE is a 10 A, 250 V AC/DC slow-blow glass cartridge fuse with a 5mm x 20mm form factor, designed for through-hole mounting applications. This part carries an obsolete product status, making identification of active equivalent and substitute components essential for ongoing system support and procurement.

The primary reason for identifying substitutes is the obsolete classification of the 0218010.MXE. Active alternatives ensure design continuity, supply chain reliability, and compliance with current regulatory standards including RoHS3 and REACH requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0218010.MXE is determined by strict equivalence across the following 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 form factor (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Breaking Capacity: 100 A @ rated voltage (exact match required)
• Operating Temperature: -55°C to 125°C (exact match required)

Two substitute parts meet these criteria: the Littelfuse 0218010.MXEP (parametric equivalent with active status) and the SCHURTER 0034.3127 (direct manufacturer alternative). Both components satisfy all electrical and mechanical parameters required for functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Littelfuse 0218010.MXEP is the primary substitute for the obsolete 0218010.MXE. Both components are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications. The 0218010.MXEP carries active product status and holds ROHS3 compliance with expanded regulatory approvals (CE, K-MARK, PSE, VDE) compared to the original part. This substitute provides direct compatibility with existing through-hole mounting designs without modification.

SCHURTER 0034.3127 is a secondary substitute that meets all electrical parameters but requires a fuse holder for mounting, unlike the through-hole design of the original part. This component is ROHS3 compliant and holds approvals from CQC, cURus, PSE/JET, and VDE. Selection of this part requires mechanical redesign to accommodate the holder requirement.

For applications requiring no design modification, the Littelfuse 0218010.MXEP is the recommended substitute. For applications where holder-based mounting is acceptable or preferred, the SCHURTER 0034.3127 provides an alternative with equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 0218010.MXEP be used as a direct replacement for the 0218010.MXE?

A: Yes. Both components share identical current rating (10 A), voltage rating (250 V AC), response time (slow blow), package dimensions (5mm x 20mm), and mounting type (through hole). The 0218010.MXEP is electrically and mechanically compatible with existing designs using the 0218010.MXE.

Q: What is the primary difference between the 0218010.MXEP and the 0034.3127?

A: The primary difference is mounting type. The 0218010.MXEP is designed for direct through-hole mounting, while the 0034.3127 requires a separate fuse holder. Both meet identical electrical specifications (10 A, 250 V AC, slow blow, 100 A breaking capacity).

Q: Are there compliance differences between these substitutes?

A: Yes. The 0218010.MXE is RoHS non-compliant. Both the 0218010.MXEP and 0034.3127 are ROHS3 compliant. The 0218010.MXEP holds broader regulatory approvals (CE, CSA, K-MARK, PSE, UL, VDE) compared to the 0034.3127 (CQC, cURus, PSE/JET, VDE).

Q: Does the SCHURTER 0034.3127 require design changes?

A: Yes. The 0034.3127 requires a fuse holder for mounting, whereas the original 0218010.MXE and substitute 0218010.MXEP are through-hole components. Designs using the 0034.3127 must incorporate an appropriate fuse holder assembly.

Q: What is the significance of the Melting I²t values?

A: Melting I²t indicates the thermal energy required to melt the fuse element. The 0218010.MXE has a Melting I²t of 583, the 0218010.MXEP is 568, and the 0034.3127 is 520. These variations reflect minor differences in fuse element design but do not affect functional equivalence for the specified 10 A, 250 V slow-blow application.
