Littelfuse 0301025.M Glass Cartridge Fuse 25A 32VAC/VDC 1AG Equivalent & Substitute Parts

Part Overview

The Littelfuse 0301025.M is a 25A 32VAC/VDC glass cartridge fuse in 1AG form factor (1/4" x 5/8"). This component is classified as obsolete, necessitating identification of active equivalent parts for continued system support and procurement. The fuse requires a compatible holder for installation and operates within the specified voltage and current parameters for general-purpose circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0301025.M is determined by strict equivalence across the following parameters: current rating (25A), AC voltage rating (32V), DC voltage rating (32V), fuse type (cartridge glass), package designation (1AG), and physical dimensions (0.250" Dia x 0.625" L). Parts meeting all these criteria are classified as parametric equivalents. The primary distinction between substitute options is product status (active vs. obsolete) and manufacturer source.

Parameter Comparison

Engineering Selection Recommendations

Both 0AGA025.V (Littelfuse) and AGA-25 (Eaton) are active product alternatives to the obsolete 0301025.M. The 0AGA025.V maintains continuity within the Littelfuse product line and shares identical electrical and mechanical specifications. The AGA-25 from Eaton provides cross-manufacturer equivalence with documented breaking capacity (1kA) and UR approval agency certification. Selection between these options depends on supply chain preference, existing inventory management protocols, and manufacturer qualification requirements within the application system.

Frequently Asked Questions (FAQ)

Q: Can 0AGA025.V directly replace 0301025.M? A: Yes. Both parts share identical current rating (25A), voltage ratings (32VAC/32VDC), fuse type (cartridge glass), package designation (1AG), and physical dimensions (0.250" Dia x 0.625" L). The primary difference is product status: 0301025.M is obsolete while 0AGA025.V is active.

Q: What is the difference between Littelfuse and Eaton AGA-25 fuses? A: Both meet the same electrical and mechanical parameters (25A, 32VAC/32VDC, 1AG package). The Eaton AGA-25 specifies fast-blow response time, 1kA breaking capacity, and UR approval. Littelfuse 0AGA025.V does not document these additional characteristics in the provided specifications.

Q: Are all three parts physically interchangeable? A: Yes. All three parts conform to the 1AG form factor with identical dimensions (0.250" Dia x 0.625" L) and require the same holder type for installation.

Q: Does RoHS compliance affect substitution? A: All three parts are RoHS non-compliant. Substitution does not change compliance status. Applications requiring RoHS-compliant components require alternative part families.

Q: What inventory status should influence procurement decisions? A: 0301025.M (1052 pcs), 0AGA025.V (803 pcs), and AGA-25 (1057 pcs) are all currently in stock. Procurement should prioritize active products (0AGA025.V or AGA-25) to avoid future obsolescence issues.
