Littelfuse 036201.5M Equivalent & Substitute Parts

Part Overview

The Littelfuse 036201.5M is a 1.5 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 ongoing system maintenance and repair operations. The part requires a dedicated fuse holder for installation and is commonly used in low-voltage DC and AC circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

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

• Current Rating: 1.5 A (must match exactly)
• Fuse Type: Cartridge, Glass (form factor compatibility)
• Package / Case: 8AG, 1/4" x 1" (physical and holder compatibility)
• Response Time: Fast Blow (electrical characteristic)
• Mounting Type: Requires Holder (installation requirement)

The substitute part Eaton BK/AGX-1-1/2 meets all these core criteria. While the substitute offers higher voltage ratings (250 V AC vs. 32 V AC/DC), this represents an enhancement in capability and does not compromise compatibility in lower-voltage applications. The identical current rating, fuse type, package designation, and response time ensure functional equivalence in the circuit protection role.

Parameter Comparison

Engineering Selection Recommendations

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

• Active product status ensures ongoing availability and supply chain continuity
• Identical current rating (1.5 A) and response time (Fast Blow) maintain circuit protection characteristics
• Matching 8AG package and physical form factor ensure compatibility with existing fuse holders
• Higher voltage rating (250 V AC/DC) provides enhanced capability without compromising performance in 32 V applications
• cULus approval certification provides recognized safety compliance documentation
• Specified breaking capacity (100 A) offers defined electrical performance metrics

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/AGX-1-1/2 be used as a direct replacement for the Littelfuse 036201.5M?

A: Yes. Both fuses share identical current ratings (1.5 A), response time (Fast Blow), and 8AG package designation. The substitute will function in the same holder and provide equivalent circuit protection.

Q: Why does the Eaton substitute have a higher voltage rating?

A: The Eaton BK/AGX-1-1/2 is rated for 250 V AC/DC compared to the Littelfuse 32 V rating. Higher voltage ratings indicate enhanced insulation and design margins. This does not affect operation in lower-voltage circuits and represents an improvement in component capability.

Q: Are there physical dimension differences between these fuses?

A: The Eaton substitute is 0.042" longer (1.042" vs. 1.000"). Both maintain the 0.250" diameter and 8AG designation. This minor length difference does not affect holder compatibility.

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

A: cULus certification indicates the component meets safety standards recognized in North American markets. This provides documented compliance for applications requiring third-party safety validation.

Q: Why is the Littelfuse part marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Eaton substitute ensures continued availability for replacement and maintenance applications.
