Littelfuse 0362.500V Fuse Cartridge - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0362.500V is a 500 mA fast-blow glass fuse cartridge rated for 32 V AC and 32 V DC operation in the 8AG form factor (1/4" x 1"). This component is classified as obsolete and requires a compatible fuse holder for installation. Due to its obsolete status, identifying suitable substitute components is necessary for ongoing system maintenance and new design implementations where equivalent electrical and mechanical specifications are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Littelfuse 0362.500V is determined by the following critical parameters:

• Current Rating: Must be 500 mA (exact match)
• Fuse Type: Must be Cartridge, Glass (mechanical and electrical compatibility)
• Package / Case: Must be 8AG, 1/4" x 1" (physical fit in existing holders)
• Response Time: Must be Fast Blow (circuit protection characteristic)
• Voltage Rating - AC: Substitute must meet or exceed 32 V AC
• Voltage Rating - DC: Substitute must meet or exceed 32 V DC

The Eaton BK/AGX-1/2 meets all substitution criteria with a higher voltage rating (250 V AC) and active product status, making it suitable for direct replacement in applications where the original 0362.500V is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The Eaton BK/AGX-1/2 is the qualified substitute for the obsolete Littelfuse 0362.500V based on the following factors:

• Electrical Compatibility: Both components share identical 500 mA current ratings and fast-blow response characteristics. The Eaton substitute provides a higher AC voltage rating (250 V vs. 32 V), ensuring operation within the original application's voltage envelope.
• Mechanical Compatibility: Both fuses conform to the 8AG form factor and require compatible holders. Physical dimensions are nearly identical, with the Eaton part measuring 0.042" longer, which does not affect holder compatibility.
• Product Status and Support: The Eaton BK/AGX-1/2 maintains active product status with established supply chains, addressing the obsolescence of the original Littelfuse component.
• Regulatory Compliance: The Eaton substitute carries cULus approval, providing third-party certification for safety-critical applications. Both components share RoHS non-compliant status.

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/AGX-1/2 be used as a direct replacement for the Littelfuse 0362.500V?

A: Yes. Both components share identical current ratings (500 mA), response time (fast blow), and 8AG package specifications. The Eaton substitute is mechanically and electrically compatible with existing Littelfuse 0362.500V holders and circuits.

Q: What is the significance of the higher voltage rating on the Eaton substitute?

A: The Eaton BK/AGX-1/2 is rated for 250 V AC, compared to the original 32 V AC rating. A higher voltage rating does not affect operation in lower-voltage circuits; the fuse will function identically in 32 V applications. This characteristic provides design flexibility for future applications requiring higher voltage operation.

Q: Are there physical fit concerns due to the slight length difference?

A: The Eaton BK/AGX-1/2 measures 0.042" longer than the original (26.47mm vs. 25.40mm). This minimal difference does not affect compatibility with standard 8AG fuse holders, which are designed with sufficient internal clearance to accommodate normal manufacturing tolerances.

Q: What certifications apply to the substitute component?

A: The Eaton BK/AGX-1/2 carries cULus approval, indicating compliance with UL and CSA safety standards. This certification supports use in regulated and safety-critical applications.

Q: Why is the DC voltage rating not specified for the Eaton substitute?

A: The provided data does not include a separate DC voltage rating for the Eaton BK/AGX-1/2. For DC applications, consult the manufacturer's technical documentation or contact Eaton directly to confirm DC operating parameters.
