Littelfuse 0LMF003.V Fuse Cartridge - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0LMF003.V is a 3A 300VAC slow-blow cartridge fuse designed for inline electrical and industrial applications. This POWR-GARD® LMF series component requires a compatible fuse holder for installation. The part maintains active product status with 814 units in current inventory. Substitute parts are identified to support procurement flexibility, supply chain continuity, and application requirements where the original part may be unavailable or where equivalent electrical and mechanical specifications are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 0LMF003.V are identified based on strict equivalence of the following critical parameters:

• Current Rating: 3A
• Voltage Rating (AC): 300VAC
• Fuse Type: Cartridge
• Response Time: Slow Blow
• Package / Case: Cartridge
• Size / Dimension: 0.610" Dia x 1.820" L (15.49mm x 46.23mm)
• Breaking Capacity @ Rated Voltage: 10kA

The Eaton GMF-3 meets these electrical and mechanical specifications, enabling functional equivalence in applications requiring inline 3A 300VAC slow-blow cartridge fuses with identical physical dimensions and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 0LMF003.V is the primary specification for applications requiring ROHS3 compliance and multi-agency certification (CE, CSA, UL). This part is actively manufactured and maintains adequate inventory.

The Eaton GMF-3 provides electrical equivalence at the rated current and voltage specifications. However, the following differences must be evaluated for specific applications:

• RoHS Compliance: The Eaton GMF-3 is RoHS non-compliant, which may disqualify it from applications subject to RoHS3 regulatory requirements.
• Certifications: Approval agency certifications are not specified for the Eaton GMF-3, requiring verification against application-specific compliance mandates.
• Response Time and Breaking Capacity: These parameters are not specified for the Eaton GMF-3, necessitating confirmation that performance characteristics are equivalent to the Littelfuse specification.

Selection of the Eaton GMF-3 is appropriate only when RoHS3 compliance and multi-agency certification are not required, and when the unspecified performance parameters have been independently verified as acceptable for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the Eaton GMF-3 be used as a direct replacement for the Littelfuse 0LMF003.V?

A: The Eaton GMF-3 matches the critical electrical specifications (3A, 300VAC) and physical dimensions (0.610" Dia x 1.820" L). However, RoHS compliance status and regulatory certifications differ. Substitution is permissible only when these compliance requirements are not mandated by application or regulatory standards.

Q: What are the key parameters that determine fuse substitutability?

A: Current rating, voltage rating, fuse type, response time, physical dimensions, breaking capacity, and mounting requirements are the primary parameters. All must align between the original and substitute part for functional equivalence.

Q: Does the Eaton GMF-3 require the same holder as the Littelfuse 0LMF003.V?

A: Both parts are cartridge-type fuses with identical physical dimensions (0.610" Dia x 1.820" L), indicating mechanical compatibility with the same holder. Verification with the holder manufacturer is recommended.

Q: What is the significance of the RoHS3 compliance difference?

A: RoHS3 compliance is mandatory for products sold in the European Union and for many industrial applications subject to environmental regulations. The Littelfuse 0LMF003.V meets this requirement; the Eaton GMF-3 does not. Application regulatory requirements must be confirmed before substitution.

Q: Are the approval agencies (CE, CSA, UL) certifications critical for substitution?

A: Certification requirements depend on the application and end-use market. Equipment designed for North American markets typically requires UL certification. European markets require CE marking. Verification of certification requirements against application standards is necessary before substitution.
