LMIN004.V Automotive Fuse - Equivalent & Substitute Parts

Part Overview

The LMIN004.V is a 4A 32V AC/DC automotive blade fuse manufactured by Littelfuse Inc., part of the LP MINI® 891 series. This component is designed for automotive electrical circuit protection and requires a compatible fuse holder for installation. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing maintenance and repair applications where this fuse type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMIN004.V is determined by strict equivalence across the following critical parameters:

• Current Rating: 4 A (exact match required)
• Voltage Rating: 32 V AC and 32 V DC (exact match required)
• Response Time: Fast Blow (exact match required)
• Fuse Type: Automotive (exact match required)
• Approval Agency: SAE and UL certification (required for automotive applications)
• RoHS Compliance: ROHS3 Compliant (required for regulatory compliance)

The substitute part 0MIN004.V meets all these criteria. Minor variations in physical dimensions and packaging format do not affect electrical or functional compatibility, provided the fuse holder accommodates the blade miniature form factor.

Parameter Comparison

Engineering Selection Recommendations

The 0MIN004.V is a direct electrical and functional equivalent to the LMIN004.V. Both components are manufactured by Littelfuse Inc. and carry identical electrical specifications: 4A current rating, 32V AC/DC voltage rating, and fast-blow response characteristics. Both hold SAE and UL approvals required for automotive circuit protection applications and maintain ROHS3 compliance.

The primary distinction is product status: LMIN004.V is obsolete while 0MIN004.V is active. For new designs or replacement applications, 0MIN004.V is the appropriate selection. The minor dimensional variation (0.331" H vs. 0.346" H) reflects standard manufacturing tolerances within the blade miniature form factor and does not affect holder compatibility or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can 0MIN004.V be used as a direct replacement for LMIN004.V?

A: Yes. Both fuses are electrically identical with matching current ratings (4A), voltage ratings (32V AC/DC), response time (fast blow), and automotive approvals (SAE, UL). The substitute is functionally equivalent for all circuit protection applications.

Q: What is the significance of the product status difference?

A: LMIN004.V is classified as obsolete, indicating it is no longer manufactured or supported. 0MIN004.V is active production, ensuring availability and continued manufacturer support. For replacement or new applications, 0MIN004.V should be specified.

Q: Are there dimensional compatibility concerns?

A: Both fuses use the blade miniature form factor and are designed for standard automotive fuse holders. The height difference (0.331" vs. 0.346") falls within normal manufacturing tolerances for this package type and does not affect holder compatibility.

Q: Do both fuses meet the same regulatory requirements?

A: Yes. Both LMIN004.V and 0MIN004.V carry SAE and UL certifications and are ROHS3 compliant, meeting automotive and environmental regulatory standards.

Q: What is the difference between LP MINI® 891 and MINI® series designations?

A: Both designations refer to Littelfuse miniature blade fuse series. The series designation does not affect electrical equivalence or substitution compatibility when all electrical parameters match.
