NON-6 Equivalent & Substitute Parts

Part Overview

The NON-6 is a 6A ceramic cartridge fuse manufactured by Eaton - Bussmann Electrical Division, rated for 250V AC and 125V DC operation. This slow-blow fuse is designed for applications requiring a non-standard cartridge holder and is currently in active production status with 866 units in stock. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and approval certifications align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NON-6 is determined by strict alignment of the following electrical and mechanical parameters:

• Current Rating: 6A (exact match required)
• Voltage Rating - AC: 250V minimum
• Voltage Rating - DC: Must support circuit requirements
• Fuse Type: Cartridge configuration
• Package / Case: Non-standard cartridge dimensions
• Physical Dimensions: 0.560" Dia x 2.000" L tolerance
• Breaking Capacity: 50kA or greater at rated voltage
• Approval Certifications: CE, CSA, UL compliance

The 0NLN006.T from Littelfuse Inc. meets these substitution criteria with compatible electrical ratings and mechanical form factor, though response time characteristics differ.

Parameter Comparison

Engineering Selection Recommendations

Both the NON-6 and 0NLN006.T cartridge fuses carry identical approval certifications (CE, CSA, UL) and maintain active product status. The 0NLN006.T provides equivalent or superior voltage ratings and breaking capacity for AC applications. Selection between these parts should account for the response time difference: the NON-6 operates as slow-blow while the 0NLN006.T operates as fast-blow. This characteristic difference may affect circuit protection behavior and must be evaluated against specific application requirements. Both parts are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can the 0NLN006.T directly replace the NON-6 in all applications?

A: The 0NLN006.T meets the electrical and mechanical substitution criteria for 6A, 250V AC circuits. However, the response time difference (fast-blow vs. slow-blow) may affect circuit behavior. Verify that the substitute's fast-blow characteristic is compatible with your application's inrush current profile.

Q: Are the physical dimensions identical between these parts?

A: The NON-6 measures 0.560" Dia x 2.000" L while the 0NLN006.T measures 0.563" Dia x 2.000" L. The diameter difference of 0.003" is within typical mechanical tolerance for non-standard cartridge holders.

Q: What is the significance of the different DC voltage ratings?

A: The NON-6 is rated for 125V DC while the 0NLN006.T is rated for 250V DC. For DC applications, the 0NLN006.T provides higher voltage capability. For circuits operating at or below 125V DC, both parts are suitable.

Q: Do both parts require the same holder?

A: Both parts are non-standard cartridge fuses requiring a compatible holder. Verify that your existing holder accommodates the slight diameter variation (0.560" vs. 0.563") before substitution.

Q: Are there RoHS compliance differences between these parts?

A: The NON-6 is RoHS non-compliant while the 0NLN006.T is ROHS3 compliant. For applications with RoHS requirements, the 0NLN006.T is the appropriate selection.
