Littelfuse 0301006.H Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0301006.H is a 6 A, 32 V AC/DC glass cartridge fuse in the 1AG form factor (1/4" x 5/8"). This medium-blow fuse is designed for applications requiring holder-based installation and is currently in active production status. Substitute parts are identified when equivalent electrical and mechanical specifications are required for component sourcing, inventory management, or design standardization across manufacturing environments.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 0301006.H are identified based on the following critical parameters that determine functional equivalence:

• Current Rating: 6 A (exact match required)
• Package / Case: 1AG, 1/4" x 5/8" (mechanical compatibility with existing holders)
• Fuse Type: Cartridge, Glass (form factor and construction method)
• Mounting Type: Requires Holder (installation method compatibility)

The Eaton AGA-6 is listed as a manufacturer-recommended substitute. While the AGA-6 operates at a higher voltage rating (125 V AC versus 32 V AC), it maintains identical current rating, package dimensions, and mechanical form factor. The higher voltage rating does not preclude substitution in 32 V applications, as fuses rated for higher voltages are suitable for lower-voltage circuits. The AGA-6 differs in response time classification (Fast Blow versus Medium Blow) and includes a specified breaking capacity (1 kA) and DC cold resistance (0.015 Ohms).

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 0301006.H and Eaton AGA-6 are active production components with identical RoHS compliance status and moisture sensitivity ratings. Selection between these parts should be based on application-specific requirements:

The Littelfuse 0301006.H is the primary specification for 32 V AC/DC circuits requiring medium-blow response characteristics. The Eaton AGA-6 provides an alternative source with identical current rating and mechanical compatibility but operates at 125 V AC rating with fast-blow response time. The higher voltage rating of the AGA-6 provides broader application coverage in lower-voltage circuits.

Both components are suitable for applications where 1AG form factor holders are specified and where RoHS non-compliance is acceptable for the end application.

Frequently Asked Questions (FAQ)

Q: Can the Eaton AGA-6 be used as a direct replacement for the Littelfuse 0301006.H?

A: Yes, from a mechanical and electrical compatibility standpoint. Both fuses share identical current rating (6 A), package dimensions (1AG, 1/4" x 5/8"), and mounting requirements (holder-based installation). The AGA-6 operates at a higher voltage rating (125 V versus 32 V), which is acceptable for lower-voltage applications. However, the difference in response time (Fast Blow versus Medium Blow) should be evaluated against circuit protection requirements.

Q: What does the 1AG package designation mean?

A: 1AG refers to a standardized glass cartridge fuse form factor with dimensions of 1/4" diameter by 5/8" length (6.35mm x 15.88mm). This designation indicates mechanical compatibility with 1AG fuse holders and is a universal industry standard for this size class.

Q: Are there differences in breaking capacity between these fuses?

A: The Eaton AGA-6 specifies a breaking capacity of 1 kA at rated voltage. The Littelfuse 0301006.H does not include a specified breaking capacity in the provided data. Breaking capacity represents the maximum fault current the fuse can safely interrupt without rupturing the fuse body.

Q: What is the significance of response time classification?

A: Response time classification (Medium Blow versus Fast Blow) indicates how quickly the fuse element melts under overcurrent conditions. Medium-blow fuses tolerate brief current surges before opening, while fast-blow fuses open more rapidly. Application circuit characteristics determine which classification is appropriate.

Q: Can these fuses be used in DC applications?

A: Both fuses are rated for AC/DC operation at their respective voltage ratings. The 0301006.H is rated 32 V AC/DC, and the AGA-6 is rated 125 V AC/DC. DC applications should be evaluated against the specified voltage and current ratings.
