Littelfuse 0362005.M Equivalent & Substitute Parts

Part Overview

The Littelfuse 0362005.M is a 5 A, 32 V AC/DC fast-blow glass cartridge fuse in 8AG form factor (1/4" x 1"). This component is classified as obsolete, making identification of compatible substitutes essential for system maintenance and repair applications. The 8AG package and cartridge-glass construction define the mechanical and electrical compatibility envelope for alternative parts.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0362005.M is determined by the following critical parameters:

• Current Rating: Must be 5 A (exact match required)
• Package / Case: Must be 8AG, 1/4" x 1" (mechanical compatibility with existing holders)
• Fuse Type: Must be Cartridge, Glass (functional and form-factor requirement)
• Response Time: Must be Fast Blow (circuit protection characteristic)
• Voltage Rating - AC: Substitute must support minimum 32 V AC; higher ratings are acceptable
• Voltage Rating - DC: Substitute must support minimum 32 V DC; higher ratings are acceptable
• Mounting Type: Must require holder (no change in installation method)

The Eaton BK/AGX-5 meets all substitution criteria. While it features higher voltage ratings (250 V AC/DC versus 32 V AC/DC), this represents an upward-compatible specification suitable for low-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

The Eaton BK/AGX-5 is the qualified substitute for the obsolete Littelfuse 0362005.M based on the following factors:

• Electrical Compatibility: Identical 5 A current rating and fast-blow response time. The 250 V AC/DC rating exceeds the 32 V requirement, providing upward-compatible voltage margin for low-voltage circuit protection.
• Mechanical Compatibility: 8AG package form factor ensures direct installation in existing fuse holders. The 0.042" length difference (26.47 mm versus 25.40 mm) is within standard mechanical tolerance for cartridge fuse holders.
• Product Status: The BK/AGX-5 is active and in production, ensuring long-term availability and supply continuity.
• Regulatory Compliance: The BK/AGX-5 carries cULus approval, providing recognized safety certification for component selection.

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/AGX-5 be used in place of the Littelfuse 0362005.M?

A: Yes. Both components share identical current rating (5 A), response time (fast blow), fuse type (cartridge glass), and 8AG package form factor. The higher voltage rating of the BK/AGX-5 (250 V AC/DC) is compatible with 32 V AC/DC applications.

Q: Will the BK/AGX-5 fit in the existing fuse holder?

A: Yes. The 8AG package specification ensures mechanical compatibility. The 0.042" length difference is within standard tolerance for cartridge fuse holders designed for 8AG components.

Q: What is the significance of the higher voltage rating on the BK/AGX-5?

A: A higher voltage rating indicates the component can safely operate in circuits with higher voltage stress. In a 32 V application, the 250 V rated fuse provides additional safety margin and is a standard engineering practice for component substitution.

Q: Are there any compliance differences between the two parts?

A: The Littelfuse 0362005.M does not specify approval agency certification. The Eaton BK/AGX-5 carries cULus approval, providing recognized safety certification for regulated applications.

Q: Why is the Littelfuse 0362005.M classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Eaton BK/AGX-5 is an active, in-production alternative that meets all functional and mechanical requirements.
