Key Parameters

Substitute Part Grouping Explanation

The substitute part BK/5960-44 is classified as an equivalent component based on the following critical parameters that determine functional interchangeability:

Matching Parameters:

• Mounting Type: Chassis Mount
• Fuse Size: 0.394" Dia (10mm)
• Fuse Type: Cartridge
• Fuseholder Type: Clip
• Number of Circuits: 1
• Termination Style: Screw Terminal
• Contact Material: Spring Bronze
• Series: 5000
• HTSUS Code: 8538.90.8180

Differing Parameters:

• Contact Finish: Tin (5960-63-R) vs. Nickel (BK/5960-44)
• Product Status: Obsolete (5960-63-R) vs. Active (BK/5960-44)
• RoHS Status: Not specified (5960-63-R) vs. RoHS Compliant (BK/5960-44)

The BK/5960-44 maintains identical mechanical and electrical specifications for fuse accommodation and circuit protection function. The contact finish difference (tin vs. nickel) represents a material upgrade that does not compromise compatibility with standard 10mm cartridge fuses.

Parameter Comparison

Engineering Selection Recommendations

The BK/5960-44 is the direct substitute for the obsolete 5960-63-R. Both components share identical mechanical mounting, fuse accommodation specifications, and electrical termination characteristics. The BK/5960-44 is currently in active production status with RoHS compliance certification, making it the appropriate selection for new designs and replacement applications. The nickel contact finish on the BK/5960-44 provides enhanced corrosion resistance compared to the tin finish of the original part, supporting long-term reliability in operational environments.

Frequently Asked Questions (FAQ)

Q: Can BK/5960-44 be used as a direct replacement for 5960-63-R in existing assemblies?

A: Yes. Both components are designed for identical 10mm cartridge fuses, use screw terminal connections, and feature spring bronze contacts. The mechanical and electrical interface specifications are equivalent.

Q: What is the significance of the contact finish difference between tin and nickel?

A: Contact finish affects corrosion resistance and long-term contact reliability. Nickel provides superior corrosion protection in humid or chemically active environments. The BK/5960-44 with nickel finish represents a material upgrade that does not affect fuse compatibility or electrical performance.

Q: Why is the 5960-63-R classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Eaton - Bussmann Electrical Division. The BK/5960-44 is the active production equivalent that fulfills the same functional requirements.

Q: Does RoHS compliance affect the substitution decision?

A: RoHS compliance on the BK/5960-44 indicates conformance to hazardous substance restrictions. This certification supports use in regulated applications and modern supply chain requirements. The original 5960-63-R does not specify RoHS status.

Q: Are there any packaging differences between these parts?

A: The 5960-63-R is specified with standard packaging, while the BK/5960-44 is supplied in bulk packaging. This difference does not affect component functionality or interchangeability.
