Littelfuse 0LEB0JJSX Fuse Holder - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0LEB0JJSX is a cartridge fuse holder rated for 30 A at 600V, designed for single-circuit applications with free-hanging (in-line) mounting. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. The substitute part 0LEB0JJSXK maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 0LEB0JJSXK is classified as a direct equivalent based on the following matching parameters:

• Current Rating: 30 A (identical)
• Voltage Rating: 600V (identical)
• Fuse Size: 0.394" Dia x 1.496" L / 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 and product status. The original part features screw terminal termination and is obsolete, while the substitute employs crimp termination and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The 0LEB0JJSXK is the direct equivalent for the obsolete 0LEB0JJSX. Both parts satisfy identical electrical requirements (30 A, 600V) and mechanical specifications (10mm x 38mm cartridge fuse accommodation). The substitute maintains ROHS3 compliance and copper contact construction.

The primary consideration for selection is termination compatibility. The original part uses screw terminal connections, while the substitute employs crimp termination. Circuit design must accommodate the crimp connection method. The substitute's active product status ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 0LEB0JJSXK replace the 0LEB0JJSX in existing applications?

A: Yes, provided the circuit design accommodates crimp termination instead of screw terminal connections. All electrical and mechanical parameters are identical.

Q: What is the difference between screw terminal and crimp termination?

A: Screw terminal connections use a mechanical fastener to secure wire leads, while crimp termination requires pre-crimped connectors pressed onto wire ends. Both methods provide secure electrical connections; selection depends on assembly process and equipment availability.

Q: Are both parts compatible with 5AG midget fuses?

A: Yes. Both the 0LEB0JJSX and 0LEB0JJSXK accommodate 5AG cartridge fuses measuring 13/32" x 1-1/2" (10mm x 38mm).

Q: Why is the original part obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The 0LEB0JJSXK represents the active equivalent and is the recommended selection for new designs and ongoing procurement.

Q: Do both parts meet RoHS requirements?

A: Yes. Both parts are ROHS3 compliant and suitable for applications requiring RoHS certification.
