Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JJN-60 is determined by strict equivalence across the following parameters:

• Current Rating: 60A (exact match required)
• Voltage Ratings: 300 VAC and 160 VDC (both must be met or exceeded)
• Response Characteristic: Fast Blow (Class T)
• Breaking Capacity: 200kA AC and 20kA DC minimum
• Physical Form Factor: Cartridge type requiring holder
• Regulatory Compliance: CE, CSA, and UL certifications

The substitute part JLLN060.T from Littelfuse Inc. satisfies all substitution criteria through identical electrical ratings, equivalent breaking capacity, and compatible physical dimensions within acceptable tolerance ranges.

Parameter Comparison

Engineering Selection Recommendations

The JLLN060.T cartridge fuse from Littelfuse Inc. is a direct electrical and mechanical equivalent to the JJN-60. Both components maintain active product status and satisfy identical electrical specifications including current rating, voltage ratings, breaking capacity, and response characteristics. Dimensional compatibility is confirmed within standard manufacturing tolerances. Both parts carry equivalent regulatory certifications (CE, CSA) with the Littelfuse part certified to UR in addition to UL. RoHS3 and REACH compliance status are identical. Selection between these parts may be based on availability, packaging format (Littelfuse supplied in Box packaging versus Eaton in Bulk), or supply chain requirements, as no technical differentiation exists.

Frequently Asked Questions (FAQ)

Q: Can JLLN060.T be used as a direct replacement for JJN-60?

A: Yes. Both parts are rated for 60A at 300 VAC and 160 VDC with identical fast-blow response and Class T classification. Physical dimensions are compatible within standard tolerances, and both require the same holder type for installation.

Q: Are there dimensional differences between these fuses?

A: Minor dimensional variations exist within acceptable ranges. JJN-60 measures 0.560" diameter by 0.880" length, while JLLN060.T measures 0.563" diameter by 0.874" length. These differences fall within standard cartridge fuse manufacturing tolerances and do not affect holder compatibility.

Q: Do both parts have the same regulatory approvals?

A: Both parts carry CE and CSA certifications. JJN-60 holds UL approval, while JLLN060.T holds UR approval. Both certifications are recognized for industrial electrical applications.

Q: What is the difference in packaging between these parts?

A: JJN-60 is supplied in Bulk packaging, while JLLN060.T is supplied in Box packaging. This affects order quantities and storage but does not impact electrical or mechanical performance.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both JJN-60 and JLLN060.T are ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements.
