Littelfuse 0230.600MXSW Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0230.600MXSW is a 600 mA, 250 V AC glass cartridge fuse with slow-blow response characteristics, designed for through-hole mounting in non-standard axial configuration. This part is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement continuity. The substitute parts listed maintain identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0230.600MXSW is determined by strict equivalence across the following critical parameters:

• Current Rating: 600 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Size / Dimension: 0.177" Dia x 0.571" L (4.50mm x 14.50mm) (exact match required)
• Melting I²t: 1.75 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these criteria. The primary distinction between the main part and substitutes is product status (obsolete vs. active) and compliance certifications. Substitute parts offer enhanced DC voltage ratings (125 V DC) and improved RoHS compliance (ROHS3 Compliant vs. RoHS non-compliant), with equivalent or superior breaking capacity specifications.

Parameter Comparison

Engineering Selection Recommendations

All seven substitute parts (0230.600MXSP, 0230.600HXP, 0230.600HXSP, 0230.600MXP, 0230.600VXP, 0230.600VXSP) are direct parametric equivalents to the 0230.600MXSW and are suitable for replacement in applications requiring 600 mA, 250 V AC slow-blow glass cartridge fuses in non-standard axial configuration.

The primary advantages of substitution are:

• All substitute parts carry active product status, ensuring long-term availability and supply chain continuity
• All substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements
• All substitute parts include CE certification in addition to CSA and UL approvals, providing expanded market compliance
• All substitute parts specify 125 V DC voltage rating and 10 kA DC breaking capacity, offering enhanced DC circuit protection capability
• DC cold resistance values (0.4805 Ohms) are within acceptable tolerance of the main part (0.477 Ohms)

Selection among the seven substitute parts may be based on packaging preference (Bulk) and current inventory availability. All parts are manufactured by Littelfuse Inc. within the 230 series and maintain identical mechanical and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 0230.600MXSW be directly replaced with any of the listed substitute parts?

A: Yes. All seven substitute parts meet the critical electrical and mechanical parameters required for direct replacement: 600 mA current rating, 250 V AC voltage rating, slow-blow response, glass cartridge type, non-standard axial configuration, and identical physical dimensions (0.177" Dia x 0.571" L).

Q: What is the significance of the DC voltage rating difference?

A: The main part (0230.600MXSW) does not specify a DC voltage rating. All substitute parts specify 125 V DC rating with 10 kA DC breaking capacity. This enhancement provides additional protection capability in DC circuit applications without affecting AC circuit performance.

Q: Are there any compatibility concerns with the DC cold resistance variation?

A: The DC cold resistance of substitute parts (0.4805 Ohms) differs slightly from the main part (0.477 Ohms). This variation is within normal manufacturing tolerance and does not affect functional compatibility or circuit performance.

Q: Why is RoHS compliance important for this substitution?

A: The main part is RoHS non-compliant, while all substitute parts are ROHS3 compliant. ROHS3 compliance is required for products sold into markets with environmental regulations and is increasingly mandated by OEMs and procurement standards.

Q: Does the addition of CE certification affect substitution suitability?

A: No. CE certification on substitute parts represents expanded regulatory approval and does not conflict with existing CSA and UL certifications. The presence of CE certification indicates compliance with European Union directives and expands the geographic applicability of the parts.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are available in Bulk packaging. The main part packaging is listed as "-" (not specified). Bulk packaging is standard for component distribution and does not affect electrical or mechanical compatibility.

Q: How should I select among the seven substitute parts if all are equivalent?

A: Selection should be based on current inventory availability and procurement lead times. All seven parts are functionally identical and interchangeable. Consult your component supplier for stock levels and delivery schedules.
