Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Eaton 5681-08 is determined by the following critical parameters:

• Mounting Type: Must be Chassis Mount
• Fuse Size: Must accommodate 0.25" Dia (6.35mm) fuses
• Fuse Type: Must be Cartridge
• Fuseholder Type: Must be Clip-based
• Number of Circuits: Must be single circuit (1)
• Contact Material & Finish: Spring Bronze with Nickel finish ensures electrical performance and corrosion resistance

The Littelfuse 01010002Z meets all mandatory substitution criteria. While this part includes additional electrical ratings (15A at 250V), these specifications do not conflict with the base mechanical and electrical compatibility requirements for chassis-mounted 1/4" cartridge fuse clips.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 01010002Z is the qualified substitute for the obsolete Eaton 5681-08. Selection is based on:

• Mechanical Compatibility: Identical mounting type, fuse size, and clip-based design ensure direct physical replacement
• Electrical Compatibility: Matching contact material and finish maintain equivalent electrical performance
• Product Status: The Littelfuse part is active and in production, ensuring long-term availability
• Regulatory Compliance: ROHS3 compliance of the substitute part meets current environmental standards

The specified current rating (15A) and voltage rating (250V) of the Littelfuse part do not restrict its use as a substitute; these ratings define the maximum safe operating conditions and do not conflict with applications designed for the original Eaton part.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 01010002Z directly replace the Eaton 5681-08 in existing designs?

A: Yes. Both parts share identical mechanical mounting, fuse size, circuit configuration, and contact specifications. Physical and electrical compatibility is confirmed.

Q: What is the significance of the 15A and 250V ratings on the Littelfuse part?

A: These ratings specify the maximum safe operating current and voltage for the Littelfuse clip. The original Eaton part does not list these ratings, but the Littelfuse part can safely operate within these limits. If your application requires verification of current or voltage compatibility, consult your system design specifications.

Q: Why is the Eaton 5681-08 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Littelfuse 01010002Z provides functional equivalence for replacement and new applications.

Q: Are there differences in packaging between these parts?

A: The Eaton part is listed with packaging designation "-" (not specified). The Littelfuse part is supplied in Bulk packaging. Confirm packaging requirements for your procurement process.

Q: Does the ROHS3 compliance of the Littelfuse part affect compatibility?

A: No. ROHS3 compliance is an environmental standard that ensures the substitute part meets current regulatory requirements. This does not impact electrical or mechanical compatibility.
