Substitute Part Grouping Explanation

The substitute part 5674-01 is functionally equivalent to BK/5674-41-R based on the following critical parameters that determine substitutability:

• Fuse Size: 0.281" Dia (7.14mm) — identical
• Fuse Type: Cartridge — identical
• Fuseholder Type: Clip — identical
• Number of Circuits: 1 — identical
• Mounting Type: Chassis Mount — identical
• Termination Style: Screw Terminal — identical
• For Use With/Related Products: 9/32" Dia Fuses — identical
• Series: 5000 — identical
• Manufacturer: Eaton - Bussmann Electrical Division — identical

The substitute part differs in contact material (Beryllium Copper vs. Spring Bronze) and contact finish (Silver vs. Tin), as well as product status (Active vs. Obsolete). These material differences do not affect the mechanical or electrical compatibility for standard cartridge fuse applications.

Parameter Comparison

Engineering Selection Recommendations

The 5674-01 is the direct active equivalent for the obsolete BK/5674-41-R. Selection of the 5674-01 is supported by:

• Identical mechanical and electrical specifications across all critical parameters
• Active product status ensuring ongoing availability and supply chain continuity
• RoHS compliance certification, meeting current environmental and regulatory standards
• Same manufacturer and series designation, confirming design compatibility
• Equivalent ECCN and HTSUS classifications

The material differences in contact composition and finish do not compromise functional compatibility for cartridge fuse clip applications within standard operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5674-01 directly replace the BK/5674-41-R in existing designs?
