NON-15 Equivalent & Substitute Parts Reference

Part Overview

The NON-15 is a 15A 250 VAC / 125 VDC cartridge fuse manufactured by Eaton - Bussmann Electrical Division. This one-time fuse is designed for electrical and industrial applications requiring overcurrent protection in circuits rated up to 250 VAC or 125 VDC. The part is actively produced and RoHS compliant. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and functional characteristics align with the original specification, enabling direct replacement in holder-based installations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NON-15 are identified based on the following critical parameters:

• Current Rating: Must be 15A
• Voltage Rating - AC: Must be 250 VAC or higher
• Voltage Rating - DC: Must be 125 VDC or higher
• Fuse Type: Must be Cartridge
• Mounting Type: Must require holder (same mechanical interface)
• Size / Dimension: Must be compatible with standard cartridge fuse holders (0.560" Dia x 2.000" L nominal)
• Breaking Capacity: Must meet or exceed 50kA at rated voltage

The substitute part 0NLN015.T meets these criteria with equivalent current and AC voltage ratings, higher DC voltage rating (250 VDC), compatible cartridge dimensions, and equivalent breaking capacity.

Parameter Comparison

Engineering Selection Recommendations

Both the NON-15 and 0NLN015.T are active production parts with RoHS compliance. The 0NLN015.T carries additional third-party certifications (CE, CSA, UL) and provides higher DC voltage rating (250 VDC versus 125 VDC), making it suitable for applications requiring broader voltage compatibility. Dimensional tolerance between the two parts (0.560" versus 0.563" diameter) is within standard cartridge fuse holder specifications. Selection between these parts should be based on application voltage requirements and certification mandates specific to the end-use circuit.

Frequently Asked Questions (FAQ)

Q: Can the 0NLN015.T replace the NON-15 in all applications?

A: The 0NLN015.T is mechanically and electrically compatible for applications operating at or below 250 VAC and 125 VDC. The higher DC voltage rating of the substitute (250 VDC) does not restrict its use in lower-voltage circuits. Verify that the fuse holder accepts the slight diameter variation (0.563" versus 0.560").

Q: What is the difference between Class H and Class K5 fuses?

A: Class designation indicates the fuse's response characteristics and breaking capacity under fault conditions. Both classes are suitable for general electrical and industrial applications. Consult application-specific standards to confirm class requirements for your circuit.

Q: Are the dimensional differences significant?

A: The diameter difference of 0.003" (0.063mm) is within standard tolerance for cartridge fuse holders. Both parts are 2.000" in length. Mechanical fit should be verified in the specific holder used.

Q: Does the Fast Blow response time of the 0NLN015.T affect compatibility?

A: Response time classification indicates how quickly the fuse opens under overcurrent. Verify that the circuit design accommodates the substitute's response characteristics.

Q: Are both parts currently available?

A: Both the NON-15 and 0NLN015.T are active production parts with documented inventory availability.
