Littelfuse 0362005.H Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0362005.H is a 5 A, 125 V AC/DC fast-blow glass cartridge fuse in 8AG form factor (1/4" x 1"). This component is designed for circuit protection in applications requiring reliable overcurrent interruption at moderate voltage levels. The part maintains active product status with 1014 units in current inventory. Substitute parts are identified to address application requirements where voltage rating, availability, or specific certifications may necessitate alternative component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 0362005.H are identified based on the following critical parameters that determine functional interchangeability:

• Current Rating: 5 A (must match exactly)
• Fuse Type: Cartridge, Glass (must match exactly)
• Package / Case: 8AG form factor (must match exactly)
• Response Time: Fast Blow (must match exactly)
• Mounting Type: Requires Holder (must match exactly)

The Eaton BK/AGX-5 is identified as a direct substitute based on matching current rating, fuse type, package form factor, response time, and mounting requirements. The primary difference is the voltage rating, which is elevated to 250 V AC/DC, making this substitute suitable for applications where higher voltage protection is required or where component availability at the original voltage rating is constrained.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 0362005.H is the primary component for applications requiring 5 A protection at 125 V AC/DC with CSA and UL certifications. This part maintains active product status and RoHS3 compliance.

The Eaton BK/AGX-5 serves as a substitute where the following conditions apply:

• Applications operate at or below 250 V AC/DC, allowing the higher voltage rating to function safely
• cULus certification meets the application's regulatory requirements
• RoHS compliance is not a mandatory constraint for the end application
• The marginal dimensional difference (0.042" additional length) is accommodated within the fuse holder assembly

Selection between these parts should be based on voltage requirements of the specific circuit, regulatory compliance mandates, and RoHS compliance obligations of the end product.

Frequently Asked Questions (FAQ)

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

A: The Eaton BK/AGX-5 can be used in applications where the circuit voltage does not exceed 250 V AC/DC and where cULus certification is acceptable. The higher voltage rating of the substitute does not compromise protection at lower voltages. However, RoHS compliance requirements must be evaluated for the end application.

Q: What is the significance of the voltage rating difference between these parts?

A: The Littelfuse 0362005.H is rated for 125 V AC/DC, while the Eaton BK/AGX-5 is rated for 250 V AC/DC. A fuse rated for higher voltage can be safely used in lower-voltage circuits. The voltage rating indicates the maximum voltage at which the fuse can safely interrupt a fault current. Using a higher-rated fuse in a lower-voltage application does not create a safety issue.

Q: Are there dimensional compatibility concerns with the Eaton substitute?

A: The Eaton BK/AGX-5 is 0.042" longer than the Littelfuse part (1.042" versus 1.000"). Both use the 8AG form factor and require a standard 8AG fuse holder. Verify that the fuse holder assembly provides sufficient clearance for the slightly longer substitute before installation.

Q: What certifications apply to each part?

A: The Littelfuse 0362005.H carries CSA and UL approvals. The Eaton BK/AGX-5 carries cULus approval. Both certifications are recognized for electrical safety compliance. Confirm that the application's regulatory requirements accept cULus certification if substituting the Eaton part.

Q: Does RoHS compliance affect substitution decisions?

A: The Littelfuse 0362005.H is RoHS3 compliant. The Eaton BK/AGX-5 is RoHS non-compliant. If the end product must meet RoHS requirements, the Littelfuse part is the appropriate choice. If RoHS compliance is not mandated, the Eaton substitute is functionally viable.
