Equivalent & Substitute Parts for BK/SFE-14 Glass Cartridge Fuse

Part Overview

The BK/SFE-14 is a 14 A fast-blow glass cartridge fuse rated for 32 V DC operation, manufactured by Eaton - Electronics Division. This component requires a dedicated fuse holder for installation and is classified as a non-standard cartridge format. The part maintains active product status with 964 units currently in stock. Alternative equivalent parts are necessary to support supply chain flexibility, accommodate regional availability constraints, and provide options across different manufacturing sources while maintaining identical electrical and mechanical performance specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the BK/SFE-14 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 14 A
• Voltage Rating - DC: 32 V
• Fuse Type: Cartridge, Glass
• Response Time: Fast Blow
• Physical Dimensions: 0.250" Dia x 1.063" L (6.35mm x 27.00mm)
• Mounting Type: Requires Holder
• Package / Case: Cartridge, Non-Standard

All identified substitute parts meet these requirements without exception. Substitution does not require holder modification or circuit redesign. The SFE series designation confirms mechanical and electrical compatibility across all equivalent options.

Parameter Comparison

Engineering Selection Recommendations

SFE-14 (Eaton - Electronics Division): This part is manufactured by the same source as the primary component and maintains identical electrical and mechanical specifications. Both parts carry UL approval and share the same ECCN and HTSUS classifications. Selection of this substitute provides continuity with the original manufacturer while maintaining full compatibility.

0SFE014.V (Littelfuse Inc.): This substitute provides equivalent electrical performance with identical current, voltage, and response characteristics. The 0SFE014.V additionally specifies 32 V AC rating, extending operational capability beyond DC applications. This part achieves ROHS3 compliance, addressing environmental regulatory requirements where the primary BK/SFE-14 does not. Both REACH and ECCN classifications align with the primary part. Selection of this substitute is appropriate when RoHS3 compliance is a system requirement or when dual AC/DC voltage capability is beneficial.

All three parts maintain active product status and are immediately available from inventory. Selection between substitutes depends on compliance requirements and manufacturer preference rather than electrical or mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the SFE-14 and 0SFE014.V be used interchangeably with the BK/SFE-14 in existing circuits?

A: Yes. All three parts share identical current ratings (14 A), DC voltage ratings (32 V), fuse type (cartridge glass), response time (fast blow), and physical dimensions (0.250" Dia x 1.063" L). No circuit modification or holder replacement is required for substitution.

Q: What is the difference between the BK/SFE-14 and the SFE-14 from Eaton?

A: Both parts are manufactured by Eaton - Electronics Division and are electrically and mechanically identical. The primary difference is packaging description and inventory availability. The SFE-14 is listed with 722 units in stock compared to 964 units for the BK/SFE-14.

Q: Does the 0SFE014.V from Littelfuse offer any advantages over the Eaton options?

A: The 0SFE014.V provides ROHS3 compliance, which the BK/SFE-14 does not. Additionally, it specifies both 32 V AC and 32 V DC ratings, whereas the primary part specifies only DC. For applications requiring RoHS3 certification or dual AC/DC operation, the Littelfuse part offers these advantages. Inventory availability is also higher at 1102 units.

Q: Are there any approval or certification differences between these parts?

A: The BK/SFE-14 and SFE-14 both carry UL approval. The 0SFE014.V does not specify an approval agency in the provided data. All three parts share identical ECCN (EAR99) and HTSUS (8536.10.0020) classifications. RoHS compliance differs: the 0SFE014.V is ROHS3 compliant while the BK/SFE-14 is non-compliant.

Q: Does the fuse holder need to be changed when substituting these parts?

A: No. All substitute parts require the same holder type and maintain identical physical dimensions. Existing fuse holders designed for the BK/SFE-14 are fully compatible with both the SFE-14 and 0SFE014.V without modification.

Q: What does "Fast Blow" response time mean for these fuses?

A: Fast Blow indicates that these fuses are designed to open quickly under overcurrent conditions, providing rapid circuit protection. This characteristic is consistent across all three equivalent parts.

Q: Are these parts suitable for both AC and DC applications?

A: The BK/SFE-14 and SFE-14 are rated for 32 V DC operation. The 0SFE014.V is rated for both 32 V AC and 32 V DC, making it suitable for dual-voltage applications. For DC-only circuits, all three parts are appropriate.
