Key Parameters

Substitute Part Grouping Explanation

The substitute part 0LEB00JJXK is classified as a direct equivalent based on the following matching parameters:

• Current Rating: 30 A (identical)
• Voltage Rating: 600V (identical)
• Fuse Size: 10mm x 38mm (identical)
• Fuse Type: Cartridge, 5AG Midget (identical)
• Number of Circuits: 1 (identical)
• Mounting Type: Free Hanging (In-Line) (identical)
• Contact Material: Copper (identical)
• RoHS Compliance: ROHS3 Compliant (identical)

The primary distinction between these parts is the termination style: the original part uses screw terminal connections, while the substitute employs crimp termination. Both parts maintain identical electrical and mechanical specifications for fuse accommodation and circuit protection.

Parameter Comparison

Engineering Selection Recommendations

The 0LEB00JJXK is the active equivalent for the obsolete 0LEB00JJX. Both parts maintain identical electrical ratings (30 A, 600V) and mechanical specifications (10mm x 38mm cartridge fuse accommodation). The substitute part carries active product status and maintains ROHS3 compliance and EAR99 export classification.

The primary consideration for selection is termination compatibility: the original part features screw terminals, while the substitute uses crimp termination. Circuit design and wiring harness specifications must accommodate the termination style change. Both parts are suitable for single-circuit, free-hanging inline applications requiring 30 A protection at 600V.

Frequently Asked Questions (FAQ)

Q: Can 0LEB00JJXK directly replace 0LEB00JJX in existing assemblies?

A: Electrical and mechanical compatibility is confirmed across all rated parameters. Termination style differs (screw vs. crimp), requiring verification that the circuit design and wiring harness support crimp connections.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute part is in active production, ensuring availability for new designs and ongoing procurement. The obsolete status of the original part indicates discontinued manufacturing.

Q: Are the fuse cartridge specifications identical between these parts?

A: Yes. Both parts accommodate 5AG midget cartridge fuses rated 13/32" x 1-1/2" (10mm x 38mm), ensuring identical fuse compatibility.

Q: Do both parts meet current regulatory requirements?

A: Both parts are ROHS3 compliant and classified under ECCN EAR99. The substitute part includes REACH Unaffected status.

Q: What packaging options are available?

A: The original part is available in standard packaging; the substitute is supplied in bulk packaging.
