Littelfuse 0301010.M Glass Cartridge Fuse 10A 32VAC/VDC 1AG Equivalent & Substitute Parts

Part Overview

The Littelfuse 0301010.M is a 10A 32VAC/VDC glass cartridge fuse in 1AG form factor (1/4" x 5/8"). This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs. The fuse requires a compatible holder for installation and is designed for general-purpose circuit protection applications requiring 10 ampere current limiting at 32 volt AC or DC operating levels.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0301010.M are determined by strict equivalence in the following critical parameters:

• Current Rating: 10 A (exact match required)
• Voltage Rating - AC: 32 V (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 1AG, 1/4" x 5/8" (exact match required)
• Size / Dimension: 0.250" Dia x 0.625" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

Substitutes are grouped into two categories:

Parametric Equivalents (Littelfuse): Parts 0AGA010.V and 0AGA010.VP maintain identical electrical and mechanical specifications to the main part. These differ only in packaging configuration (bulk vs. 5-pack card) and product status (active vs. obsolete). Both are ROHS3 compliant.

Manufacturer Recommended Substitute (Eaton): Part BK/AGA-10 shares the same current rating (10 A), fuse type (cartridge glass), package format (1AG), and physical dimensions. However, this part operates at 125VAC with fast-blow response time and includes a breaking capacity specification of 1kA at rated voltage. The voltage rating difference (125V vs. 32V) makes this suitable only for applications where the circuit voltage does not exceed 32V AC/DC, as the fuse will provide protection at the lower voltage threshold.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): Select either 0AGA010.V or 0AGA010.VP. Both parts are active products with identical electrical and mechanical specifications to the obsolete 0301010.M. The choice between these two depends on packaging requirements: 0AGA010.V is supplied in bulk packaging, while 0AGA010.VP is supplied in 5-pack card format. Both achieve ROHS3 compliance, making them suitable for modern manufacturing environments and regulatory requirements.

For Alternative Substitution: The Eaton BK/AGA-10 is a manufacturer-recommended substitute that maintains the same current rating, fuse type, and physical form factor. This part is suitable only when the circuit voltage does not exceed 32V AC/DC. The higher voltage rating (125VAC) of this part does not prevent its use in lower-voltage circuits; however, the fast-blow response time and 1kA breaking capacity differ from the main part specifications. This option is appropriate when Littelfuse AGA equivalents are unavailable and circuit conditions permit the use of a fast-blow fuse with higher voltage rating.

Frequently Asked Questions (FAQ)

Q: Can 0AGA010.V and 0AGA010.VP be used interchangeably with 0301010.M?

A: Yes. Both parts are parametric equivalents with identical current rating (10A), voltage ratings (32VAC/32VDC), fuse type (cartridge glass), and physical dimensions (1AG, 1/4" x 5/8"). The only differences are packaging format and product status. Both are active products suitable for direct replacement.

Q: What is the difference between 0AGA010.V and 0AGA010.VP?

A: Both parts have identical electrical and mechanical specifications. The difference is packaging: 0AGA010.V is supplied in bulk packaging, while 0AGA010.VP is supplied in 5-pack card format. Selection depends on procurement and inventory requirements.

Q: Can BK/AGA-10 replace 0301010.M in all applications?

A: BK/AGA-10 is mechanically and electrically compatible for circuits operating at 32V AC or lower. The part has a higher voltage rating (125VAC) and fast-blow response time. It is suitable as a substitute when Littelfuse equivalents are unavailable, provided the circuit voltage does not exceed the 32V operating threshold of the original design.

Q: What does "Requires Holder" mean for mounting type?

A: All listed fuses are cartridge-type glass fuses that require a compatible fuse holder for installation. The holder provides electrical contact and mechanical retention. Ensure the selected fuse holder is rated for 1AG form factor (1/4" x 5/8" dimensions) and the circuit voltage and current ratings.

Q: Are there RoHS compliance differences between substitutes?

A: Yes. The Littelfuse equivalents (0AGA010.V and 0AGA010.VP) are ROHS3 compliant, while the main part (0301010.M) and Eaton substitute (BK/AGA-10) are RoHS non-compliant. For applications requiring RoHS compliance, use 0AGA010.V or 0AGA010.VP.

Q: What is the significance of "Fast Blow" response time on BK/AGA-10?

A: Fast-blow fuses interrupt circuits more quickly than standard fuses when overcurrent conditions occur. If the original circuit design requires a specific fuse response time characteristic, verify that fast-blow operation is compatible with the circuit protection scheme before substituting BK/AGA-10.
