Littelfuse 0LMF005.V Fuse Cartridge - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0LMF005.V is a 5A 300VAC slow-blow cartridge fuse designed for in-line electrical and industrial applications. This POWR-GARD® LMF series component requires a dedicated fuse holder for installation. The part maintains active product status with 701 units in current inventory. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and compliance certifications align with the original specification, enabling direct functional replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0LMF005.V are identified based on the following critical parameters that determine functional equivalence:

• Current Rating: 5A (exact match required)
• Voltage Rating: 300 VAC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Response Time: Slow Blow (exact match required)
• Physical Dimensions: 0.610" Dia x 1.820" L (exact match required for holder compatibility)
• Breaking Capacity: 10kA minimum at rated voltage
• Mounting Configuration: Requires Holder (exact match required)

The Eaton GMF-5 meets all electrical and mechanical parameters specified for the 0LMF005.V, establishing it as a manufacturer-recommended substitute. Both components share identical current, voltage, fuse type, response characteristics, and physical dimensions necessary for direct replacement in existing fuse holder installations.

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 0LMF005.V and Eaton GMF-5 are active products with identical electrical specifications (5A, 300VAC, slow-blow response) and mechanical compatibility (cartridge form factor, holder-mounted installation). Selection between these components should be based on:

• Compliance Requirements: The 0LMF005.V carries ROHS3 compliance certification. The GMF-5 is documented as RoHS non-compliant. Applications subject to RoHS3 regulatory requirements must specify the Littelfuse component.
• Certification Alignment: Both components carry EAR99 ECCN classification and share identical HTSUS codes, indicating equivalent trade compliance status.
• Supply Chain Continuity: The Eaton GMF-5 maintains higher inventory availability (1075 units) compared to the Littelfuse 0LMF005.V (701 units), relevant for high-volume procurement scenarios.
• Regulatory Environment: Installations in jurisdictions enforcing RoHS3 compliance require the Littelfuse 0LMF005.V due to the GMF-5's non-compliant status.

Frequently Asked Questions (FAQ)

Q: Can the Eaton GMF-5 be used as a direct replacement for the Littelfuse 0LMF005.V?

A: The GMF-5 provides electrical and mechanical equivalence (5A, 300VAC, slow-blow, cartridge form factor). However, RoHS3 compliance differs between components. Applications requiring ROHS3 certification must use the Littelfuse 0LMF005.V. Non-regulated applications may use either component based on availability and supply chain requirements.

Q: What determines whether a fuse can substitute for the 0LMF005.V?

A: Substitute fuses must match all of the following parameters: 5A current rating, 300VAC voltage rating, slow-blow response time, cartridge fuse type, 0.610" diameter x 1.820" length physical dimensions, and holder-mounted installation method. Deviation in any parameter eliminates substitutability.

Q: Are there dimensional compatibility concerns when switching between these fuses?

A: Both the 0LMF005.V and GMF-5 share identical physical dimensions (0.610" Dia x 1.820" L). They are mechanically interchangeable within standard cartridge fuse holders designed for these specifications.

Q: What is the significance of the breaking capacity rating?

A: The 10kA breaking capacity at rated voltage indicates the maximum fault current the fuse can safely interrupt without rupture or hazardous failure. Both components meet this specification, ensuring safe operation under fault conditions within the 300VAC system design envelope.

Q: How does RoHS3 compliance affect component selection?

A: RoHS3 compliance restricts the use of specified hazardous substances in electrical components. The Littelfuse 0LMF005.V is ROHS3 compliant; the Eaton GMF-5 is not. Installations in regulated markets or subject to RoHS3 procurement requirements must specify the compliant component.
