Littelfuse 0LEBAYCSX Fuse Holder - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0LEBAYCSX is a cartridge fuse holder rated for 30 A at 600V, designed for single-circuit applications with free-hanging (in-line) mounting. This component accommodates 5AG midget fuses (10mm x 38mm) and features crimp and screw terminal connections. The part is classified as obsolete, making identification of active equivalent models essential for procurement and system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 0LEBAYCSX is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 30 A (exact match required)
• Voltage Rating: 600V (exact match required)
• Fuse Size: 10mm x 38mm cartridge (5AG midget standard)
• Number of Circuits: 1 (single-circuit configuration)
• Mounting Type: Free Hanging (In-Line)
• Fuse Type: Cartridge
• Contact Material: Copper

The substitute part 0LEBAYCSXK maintains all critical electrical specifications and mechanical dimensions, enabling direct functional replacement. Both parts are manufactured by Littelfuse Inc. and comply with ROHS3 requirements.

Parameter Comparison

Engineering Selection Recommendations

The 0LEBAYCSXK is the active equivalent for the obsolete 0LEBAYCSX. Both parts are manufactured by Littelfuse Inc. and maintain identical electrical ratings (30 A, 600V), mechanical dimensions (10mm x 38mm cartridge), and circuit configuration (single-circuit). Both comply with ROHS3 standards and carry MSL rating 1.

The primary distinction is product status: 0LEBAYCSX is obsolete, while 0LEBAYCSXK is active and currently in production. For new designs or system replacements, 0LEBAYCSXK is the appropriate selection. The termination style difference (0LEBAYCSX offers both crimp and screw options; 0LEBAYCSXK offers crimp) must be evaluated against specific circuit board or wiring requirements.

Frequently Asked Questions (FAQ)

Q: Can 0LEBAYCSXK directly replace 0LEBAYCSX in existing applications?

A: Yes. Both parts share identical electrical ratings (30 A, 600V), fuse size (10mm x 38mm), mounting configuration (free-hanging in-line), and contact material (copper). The substitute maintains full functional compatibility.

Q: What is the significance of the product status difference?

A: 0LEBAYCSX is classified as obsolete and no longer manufactured. 0LEBAYCSXK is active and in current production, ensuring long-term availability and supply chain continuity.

Q: Does the termination style difference affect compatibility?

A: 0LEBAYCSX offers both crimp and screw terminal options, while 0LEBAYCSXK provides crimp termination. Verify that crimp termination meets your circuit connection requirements before selection.

Q: Are both parts RoHS compliant?

A: Yes. Both 0LEBAYCSX and 0LEBAYCSXK are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity level).

Q: What fuse types are compatible with these holders?

A: Both holders accommodate 5AG midget cartridge fuses with dimensions 10mm diameter x 38mm length.
