Littelfuse 0307006.H Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0307006.H is a 6 A, 32 V AC/DC fast-blow glass cartridge fuse designed for applications requiring non-standard cartridge holder mounting. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and approval certifications align with the original specification, enabling direct replacement in compatible holder assemblies.

Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 0307006.H is determined by the following criteria:

• Current Rating: Must be 6 A
• Voltage Rating: Must support 32 V DC minimum; AC rating of 32 V is preferred
• Fuse Type: Must be Cartridge, Glass with Fast Blow response
• Package / Case: Must be Cartridge, Non-Standard
• Physical Dimensions: Must be compatible with 0.250" diameter and approximately 0.750" length
• Approval Agency: UL certification required
• REACH Status: REACH Unaffected classification maintained

The Eaton BK/SFE-6 meets these substitution criteria with equivalent electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 0307006.H and Eaton BK/SFE-6 are Active product status components with UL approval and REACH Unaffected classification. The primary distinction is RoHS compliance: the Littelfuse part is RoHS3 compliant, while the Eaton substitute is RoHS non-compliant. Selection between these parts depends on application requirements for RoHS compliance. The dimensional variance of 0.002" in length (19.05mm vs. 19.00mm) is within mechanical tolerance for non-standard cartridge holder assemblies. Both parts maintain identical electrical ratings and fast-blow response characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/SFE-6 be used as a direct replacement for the Littelfuse 0307006.H?

A: Yes, provided the application does not mandate RoHS3 compliance. Both parts share identical current ratings (6 A), voltage ratings (32 V AC/DC), fuse type (Cartridge, Glass), response time (Fast Blow), and UL approval. The 0.002" dimensional difference in length is compatible with non-standard cartridge holder tolerances.

Q: What is the significance of the RoHS compliance difference?

A: The Littelfuse 0307006.H is RoHS3 compliant, restricting hazardous substances in accordance with EU Directive 2011/65/EU. The Eaton BK/SFE-6 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must use the Littelfuse part.

Q: Are the physical dimensions identical between these parts?

A: The diameter is identical at 0.250" (6.35mm). The length differs by 0.002": Littelfuse is 0.750" (19.05mm) and Eaton is 0.748" (19.00mm). This variance is within acceptable mechanical tolerance for non-standard cartridge holder assemblies.

Q: What approval certifications apply to both parts?

A: Both the Littelfuse 0307006.H and Eaton BK/SFE-6 carry UL approval and maintain REACH Unaffected status. Both are classified as Active products.

Q: How do I determine if my application requires RoHS compliance?

A: RoHS compliance is mandated for electrical and electronic equipment sold in the European Union and certain other jurisdictions. Review your application's regulatory requirements and end-market destination to determine if RoHS3 compliance is necessary.
