Equivalent & Substitute Parts for 0LMF001.V

Part Overview

The 0LMF001.V is a 1A 300VAC cartridge fuse manufactured by Littelfuse Inc. under the POWR-GARD® LMF series. This slow-blow fuse cartridge is designed for electrical and industrial applications requiring inline protection with a holder. The part is currently active in production with 759 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when supply chain considerations necessitate qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0LMF001.V is determined by the following critical parameters:

• Current Rating: 1A (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

The substitute part GMF-1 meets the electrical specifications (1A, 300V, cartridge type) and physical form factor requirements for direct substitution in applications currently using the 0LMF001.V.

Parameter Comparison

Engineering Selection Recommendations

The 0LMF001.V remains the primary specification for new designs and applications requiring ROHS3 compliance and multi-agency certification (CE, CSA, UL). The GMF-1 substitute provides electrical equivalence at 1A 300VAC but carries the following considerations:

• RoHS Compliance: GMF-1 is RoHS non-compliant, making it unsuitable for applications with RoHS requirements
• Certifications: Approval agency certifications for GMF-1 are not documented in available data
• Response Characteristics: Slow-blow response time is specified for 0LMF001.V but not confirmed for GMF-1

Selection of GMF-1 should be limited to legacy system maintenance or applications where RoHS compliance and multi-agency certification are not mandatory requirements.

Frequently Asked Questions (FAQ)

Q: Can GMF-1 be used as a direct replacement for 0LMF001.V in new designs?

A: GMF-1 matches the electrical ratings (1A, 300VAC) and cartridge form factor. However, the absence of RoHS3 compliance and unconfirmed certifications make it unsuitable for applications requiring these specifications. Use 0LMF001.V for new designs.

Q: What are the critical parameters for fuse substitution?

A: Current rating, voltage rating, fuse type (cartridge), response time (slow blow), physical dimensions, and breaking capacity must match exactly. Additionally, compliance certifications and RoHS status must meet application requirements.

Q: Does GMF-1 fit the same holder as 0LMF001.V?

A: Both parts are cartridge-type fuses with matching electrical specifications. Physical dimension compatibility with existing holders should be verified before deployment, as holder specifications are application-dependent.

Q: Are there compliance differences between these parts?

A: Yes. The 0LMF001.V is ROHS3 compliant with CE, CSA, and UL certifications. The GMF-1 is RoHS non-compliant with unspecified certifications. Applications requiring regulatory compliance must use 0LMF001.V.

Q: What is the inventory status for these parts?

A: 0LMF001.V has 759 units in stock. GMF-1 has 808 units in stock. Both are listed as active products.
