Littelfuse 0362003.M Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0362003.M is a 3 A, 32 V AC/DC glass cartridge fuse in the 8AG form factor (1/4" x 1"). This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and component procurement. The fast-blow response characteristic and compact cartridge design make this fuse suitable for low-voltage circuit protection applications requiring a holder-mounted installation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0362003.M is determined by the following critical parameters:

• Current Rating: 3 A (exact match required)
• Package / Case: 8AG, 1/4" x 1" (physical and mechanical compatibility)
• Fuse Type: Cartridge, Glass (form factor and construction method)
• Mounting Type: Requires Holder (installation method compatibility)

Two substitute parts meet these core criteria:

1. Littelfuse 0AGX003.V - Parametric equivalent with identical electrical and mechanical specifications
2. Eaton BK/AGX-3 - Manufacturer-recommended substitute with higher voltage rating and active product status

Parameter Comparison

Engineering Selection Recommendations

Littelfuse 0AGX003.V provides parametric equivalence with identical electrical specifications (3 A, 32 V AC/DC) and mechanical form factor. This part is suitable for direct replacement in applications where the original 0362003.M specifications are required. However, product status is discontinued at DiGi Electronics, which may affect long-term availability.

Eaton BK/AGX-3 is the manufacturer-recommended substitute with active product status and cULus approval certification. This part maintains the 3 A current rating and 8AG package form factor but operates at 250 V AC/DC, providing higher voltage capability. The dimensional variance (1.042" length versus 1.000") is within typical holder tolerance. This part is suitable for applications where the circuit operates at voltages below 250 V and where higher voltage margin is acceptable. Active product status ensures ongoing availability.

Selection between these substitutes depends on application voltage requirements and availability constraints. For circuits operating at or below 32 V, either part is electrically suitable. For new designs or long-term procurement, the Eaton BK/AGX-3 is preferred due to active status and regulatory certification.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0AGX003.V be used as a direct replacement for the 0362003.M?

A: Yes. The 0AGX003.V matches all critical parameters: 3 A current rating, 32 V AC/DC voltage rating, 8AG cartridge glass form factor, and 1/4" x 1" dimensions. Physical and electrical compatibility is confirmed.

Q: What is the primary difference between the Littelfuse 0AGX003.V and Eaton BK/AGX-3?

A: The Eaton BK/AGX-3 has a higher voltage rating (250 V AC/DC versus 32 V AC/DC) and is currently active in production with cULus certification. Both maintain the 3 A current rating and 8AG package form factor. The Eaton part has a slightly longer physical length (1.042" versus 1.000").

Q: Will the Eaton BK/AGX-3 fit in holders designed for the 0362003.M?

A: The 8AG package form factor is standardized. The dimensional difference of 0.042" in length is typically accommodated by standard 8AG holders. Mechanical fit should be verified for specific holder designs.

Q: Can I use the Eaton BK/AGX-3 in a 32 V circuit?

A: Yes. The Eaton BK/AGX-3 is rated for 250 V AC/DC, which exceeds the 32 V circuit requirement. The fuse will operate correctly at lower voltages within its rated capacity.

Q: Why is the 0362003.M listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Littelfuse. The 0AGX003.V and Eaton BK/AGX-3 are available alternatives that meet the same functional requirements.

Q: Are there RoHS compliance considerations for these substitutes?

A: All three parts (0362003.M, 0AGX003.V, and BK/AGX-3) are RoHS non-compliant. If RoHS compliance is required for your application, alternative fuse solutions must be evaluated.
