NON-3 Equivalent & Substitute Parts

Part Overview

The NON-3 is a one-time fuse manufactured by Eaton - Bussmann Electrical Division, currently in active product status with RoHS compliance. This component is stocked with 1108 pieces available as new original inventory. One-time fuses are essential protective devices in electrical circuits where permanent disconnection is required upon fault conditions. Identifying equivalent substitute parts becomes necessary when the primary part is unavailable or when design requirements call for alternative form factors or manufacturer sources while maintaining equivalent electrical protection characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NON-3 fuse is based on the following critical parameters derived from the provided data:

• Electrical Protection Function: One-time fuse operation with permanent circuit disconnection upon fault
• Regulatory Compliance: RoHS compliance status and international approval certifications
• Packaging Classification: Bulk packaging format
• Trade Classification: HTSUS code 8536.10.0040 alignment
• Manufacturer Availability: Active product status from qualified suppliers

The substitute part 0NLN003.T from Littelfuse Inc. qualifies as an equivalent based on matching functional classification, compliance framework, and trade code designation. This cartridge fuse maintains the protective function category while offering an alternative form factor (cartridge type requiring holder versus buss configuration).

Parameter Comparison

Engineering Selection Recommendations

Both the NON-3 and 0NLN003.T maintain active product status with current manufacturer support. The NON-3 carries RoHS compliance certification, while the 0NLN003.T achieves ROHS3 compliance, representing an enhanced compliance level. Both components share identical trade classification under HTSUS code 8536.10.0040 and ECCN designation EAR99, confirming regulatory alignment.

The 0NLN003.T substitute provides documented electrical specifications (3A, 250 VAC/VDC, Fast Blow, Class K5) with multi-agency approvals (CE, CSA, UL) and quantified breaking capacity ratings. Selection between these parts depends on circuit requirements and mechanical integration constraints, as the substitute requires a cartridge holder assembly while the original employs a buss configuration.

Frequently Asked Questions (FAQ)

Q: Can the 0NLN003.T cartridge fuse directly replace the NON-3 buss fuse?

A: Direct mechanical replacement is not possible without modification. The 0NLN003.T requires a dedicated cartridge holder assembly, whereas the NON-3 uses a buss mounting configuration. Circuit integration must accommodate this form factor difference.

Q: Are both parts compliant with current RoHS regulations?

A: Yes. The NON-3 meets RoHS compliance requirements, and the 0NLN003.T achieves the enhanced ROHS3 compliance standard. Both are suitable for applications requiring RoHS-compliant components.

Q: What electrical parameters determine substitution eligibility?

A: The provided data specifies the 0NLN003.T as a 3A, 250 VAC/250 VDC fast-blow fuse with Class K5 rating and 50kA AC / 20kA DC breaking capacity. Substitution validity depends on circuit requirements matching these electrical characteristics.

Q: Are both parts actively manufactured?

A: Yes. Both the NON-3 and 0NLN003.T maintain active product status with current inventory availability from their respective manufacturers.

Q: What certifications apply to the substitute part?

A: The 0NLN003.T carries CE, CSA, and UL approvals, providing multi-jurisdictional compliance documentation for industrial and electrical applications.
