SFE-6 Equivalent & Substitute Parts

Part Overview

The SFE-6 is a 6 A fast-blow glass cartridge fuse rated for 32 V DC operation, manufactured by Eaton - Electronics Division. This component requires an external holder for installation and is classified as a non-standard cartridge fuse. The part maintains active product status with 668 units in current inventory. Substitute parts are identified to address inventory availability, compliance requirements, or specific application needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFE-6 is determined by strict equivalence across the following parameters:

• Current Rating: 6 A (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Physical Dimensions: 0.250" Dia x 0.748" L / 6.35mm x 19.00mm (exact match required)
• Mounting Type: Requires Holder (exact match required)

All identified substitute parts meet these criteria. Additional parameters such as RoHS compliance, REACH status, and approval agencies are documented for regulatory and procurement purposes but do not affect electrical or mechanical substitutability.

Parameter Comparison

Engineering Selection Recommendations

SFE-6 (Eaton - Electronics Division): Primary part with UL approval and active product status. Recommended for applications requiring UL certification. Current inventory supports standard procurement cycles.

BK/SFE-6 (Eaton - Electronics Division): Parametric equivalent manufactured by Eaton with identical electrical and mechanical specifications. Highest inventory availability (1126 units). Suitable for direct substitution in non-RoHS-restricted applications. UL approved. Note: RoHS non-compliant status applies only if regulatory compliance is a requirement.

0SFE006.V (Littelfuse Inc.): Parametric equivalent with identical core electrical and mechanical specifications. Adds AC voltage rating capability (32 V AC) beyond the DC-only specification of the primary part. ROHS3 compliant, supporting applications with RoHS requirements. No approval agency specified. Suitable for substitution in applications where RoHS compliance is mandatory or where dual AC/DC voltage rating is beneficial.

Frequently Asked Questions (FAQ)

Q: Can BK/SFE-6 replace SFE-6 in all applications?

A: Yes. BK/SFE-6 meets all electrical and mechanical parameters required for direct substitution. Both are manufactured by Eaton and carry UL approval. The primary difference is inventory availability and RoHS compliance status. Verify RoHS requirements for your specific application.

Q: What is the difference between SFE-6 and 0SFE006.V?

A: Both parts are electrically and mechanically equivalent at 6 A, 32 V DC operation. The 0SFE006.V additionally supports 32 V AC operation. The 0SFE006.V is ROHS3 compliant, while the SFE-6 compliance status is not specified. The 0SFE006.V is manufactured by Littelfuse rather than Eaton and carries no specified approval agency.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts share identical physical dimensions (0.250" Dia x 0.748" L / 6.35mm x 19.00mm) and require the same holder cartridge. They are mechanically interchangeable.

Q: Which substitute should I select for RoHS-compliant applications?

A: Select 0SFE006.V (Littelfuse), which carries ROHS3 compliance certification. BK/SFE-6 is explicitly RoHS non-compliant.

Q: Does the AC voltage rating of 0SFE006.V affect DC-only applications?

A: No. The AC rating is an additional capability. In DC-only applications, 0SFE006.V operates identically to SFE-6 at 32 V DC, 6 A.

Q: What approval agencies certify these parts?

A: SFE-6 and BK/SFE-6 carry UL approval. 0SFE006.V has no approval agency specified in the provided data.
