Littelfuse 036201.5V Fuse Cartridge - Equivalent & Substitute Parts

Part Overview

The Littelfuse 036201.5V is a 1.5A glass cartridge fuse rated for 32V AC/DC operation in the 8AG form factor. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing system maintenance and new designs. The 8AG cartridge format (1/4" x 1") requires a compatible fuse holder for installation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Littelfuse 036201.5V is determined by the following critical parameters:

• Current Rating: 1.5 A (must match exactly)
• Fuse Type: Cartridge, Glass (form factor requirement)
• Package / Case: 8AG, 1/4" x 1" (mechanical compatibility with existing holders)
• Response Time: Fast Blow (electrical characteristic)

The Eaton BK/AGX-1-1/2 meets these core substitution criteria. While the Eaton part specifies a higher voltage rating (250V AC/DC versus 32V AC/DC), this represents an upgrade in voltage capability and does not compromise functionality in 32V circuits. The physical dimensions remain compatible with 8AG holders, and the fast-blow response characteristic is preserved.

Parameter Comparison

Engineering Selection Recommendations

The Eaton BK/AGX-1-1/2 is the designated substitute for the obsolete Littelfuse 036201.5V. Selection is based on the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• Identical current rating (1.5A) and response time (Fast Blow) preserve circuit protection characteristics
• Compatible 8AG form factor and physical dimensions enable direct installation in existing fuse holders
• Higher voltage rating (250V) provides enhanced capability without degrading performance in 32V applications
• cULus certification provides recognized safety approval for the substitute part

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/AGX-1-1/2 be used as a direct replacement in 32V circuits?

A: Yes. The Eaton part is rated for 250V AC/DC operation, which exceeds the 32V requirement of the original circuit. The 1.5A current rating and fast-blow response time remain identical, ensuring equivalent circuit protection.

Q: Are the physical dimensions compatible with existing 8AG fuse holders?

A: The Eaton part measures 0.250" Dia x 1.042" L, compared to the Littelfuse original at 0.250" Dia x 1.000" L. The 0.042" length difference is within the tolerance of standard 8AG holder design and does not prevent installation.

Q: What is the significance of the cULus certification on the Eaton part?

A: cULus certification indicates that the Eaton fuse meets safety standards established by UL (Underwriters Laboratories) and CSA (Canadian Standards Association). This certification supports compliance requirements in applications where recognized safety approvals are mandated.

Q: Why is the Littelfuse 036201.5V classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production. The Eaton BK/AGX-1-1/2 provides functional equivalence for applications requiring 1.5A, 8AG glass cartridge fuses with fast-blow characteristics.

Q: Does the higher voltage rating of the Eaton part affect its performance in lower-voltage applications?

A: No. Fuse voltage rating defines the maximum voltage at which the fuse can safely interrupt a circuit. Operating at a lower voltage (32V versus 250V rated) does not compromise the fuse's ability to protect the circuit at its specified current rating.
