Littelfuse 0362.750V Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 0362.750V is a 750 mA, 32 V AC/DC fast-blow glass cartridge fuse in the 8AG form factor (1/4" x 1"). This component is classified as obsolete, making identification of compatible substitutes essential for ongoing system maintenance and repair applications. The part requires a dedicated fuse holder for installation and is commonly used in low-voltage DC and AC circuit protection applications where fast-blow response characteristics are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Littelfuse 0362.750V is determined by the following critical parameters:

Current Rating: The substitute must match the 750 mA current rating to ensure proper circuit protection and prevent nuisance trips or inadequate protection.

Package / Case: The substitute must use the 8AG form factor (1/4" x 1" dimensions) to ensure mechanical compatibility with existing fuse holders.

Fuse Type: The substitute must be a glass cartridge fuse with fast-blow response characteristics to maintain the intended circuit protection behavior.

Voltage Rating: The substitute must support at least the voltage levels of the original part (32 V AC/DC). Higher voltage ratings are acceptable as they provide broader application compatibility.

The Eaton BK/AGX-3/4 meets all substitution criteria while offering enhanced specifications including higher voltage rating (250 V AC) and active product status with current manufacturer support.

Engineering Selection Recommendations

The Eaton BK/AGX-3/4 is the qualified substitute for the obsolete Littelfuse 0362.750V. Selection is based on the following engineering factors:

Functional Equivalence: Both parts share identical current ratings (750 mA), package form factors (8AG), and fast-blow response characteristics, ensuring direct mechanical and electrical compatibility.

Product Status: The Eaton part maintains active product status with current manufacturer support, eliminating supply chain risk associated with the obsolete Littelfuse component.

Compliance & Certification: The Eaton BK/AGX-3/4 carries cULus approval, providing recognized safety certification for circuit protection applications. The original Littelfuse part lists no approval agency.

Voltage Capability: The Eaton substitute operates at 250 V AC, exceeding the 32 V AC rating of the original part. This higher voltage rating ensures compatibility across a broader range of applications without compromising protection characteristics in lower-voltage circuits.

Electrical Performance: The Eaton part specifies a breaking capacity of 35A at rated voltage, providing documented fault interruption capability.

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/AGX-3/4 be used as a direct replacement for the Littelfuse 0362.750V?

A: Yes. Both parts share the same current rating (750 mA), package form factor (8AG, 1/4" x 1"), fuse type (glass cartridge), and response time (fast-blow). The Eaton part is mechanically and electrically compatible with existing fuse holders designed for the Littelfuse component.

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

A: The Eaton BK/AGX-3/4 operates at 250 V AC compared to the original 32 V AC rating. A higher voltage rating does not affect performance in lower-voltage circuits; it simply indicates the part can safely operate across a wider voltage range. This makes the Eaton part suitable for applications originally designed for the Littelfuse part.

Q: Are there any compatibility concerns with existing fuse holders?

A: No. Both parts use the 8AG form factor with identical physical dimensions (0.250" Dia x 1.000" L). The Eaton substitute will fit standard 8AG fuse holders without modification.

Q: Why is the Littelfuse 0362.750V listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Eaton BK/AGX-3/4 maintains active product status, ensuring ongoing availability and manufacturer support.

Q: Does the Eaton part have safety certifications?

A: Yes. The Eaton BK/AGX-3/4 carries cULus approval, a recognized certification for electrical safety in North American markets. The original Littelfuse part does not list an approval agency.
