Key Parameters

Substitute Part Grouping Explanation

Substitution of the LJ600301PR is based on electrical and mechanical parameter equivalence. The substitute part LFJ600301PID maintains identical specifications across all critical parameters: 30 A current rating, 600V voltage rating, 0.813" Dia x 2.25" L cartridge fuse size, single-circuit configuration, DIN rail mounting, and screw terminal with pressure plate termination. Both parts are designed for Class J fuses and share the same fuseholder block architecture. The substitution is valid because the electrical load capacity, voltage withstand capability, physical form factor, and connection interface are identical between the main part and substitute.

Parameter Comparison

Engineering Selection Recommendations

The LFJ600301PID is the direct equivalent substitute for the obsolete LJ600301PR. Both parts are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications. The LFJ600301PID offers the advantage of active product status, ensuring ongoing availability and manufacturer support. Additionally, the LFJ600301PID is ROHS3 compliant, whereas the LJ600301PR is RoHS non-compliant. For applications requiring RoHS compliance or where long-term component availability is critical, the LFJ600301PID is the appropriate selection. Both parts maintain equivalent moisture sensitivity levels and are suitable for Class J fuse applications in 600V, 30 A single-circuit DIN rail configurations.

Frequently Asked Questions (FAQ)

Q: Can the LFJ600301PID be used as a direct replacement for the LJ600301PR?

A: Yes. The LFJ600301PID is electrically and mechanically equivalent to the LJ600301PR. Both parts accept the same Class J cartridge fuses (0.813" Dia x 2.25" L), operate at 30 A and 600V, mount on DIN rail, and use screw terminal with pressure plate termination. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The LJ600301PR is obsolete, while the LFJ600301PID is active. The LFJ600301PID is also ROHS3 compliant, whereas the LJ600301PR is RoHS non-compliant. Functionally, both parts are identical.

Q: Are there any packaging differences between the LJ600301PR and LFJ600301PID?

A: The LJ600301PR is supplied with standard packaging, while the LFJ600301PID is supplied in a box. This difference does not affect electrical or mechanical compatibility.

Q: Which fuse types are compatible with both the LJ600301PR and LFJ600301PID?

A: Both parts are designed for Class J cartridge fuses with dimensions of 0.813" Dia x 2.25" L (20.65mm x 57.15mm) and rated for 30 A at 600V.

Q: Is the LFJ600301PID suitable for applications requiring RoHS compliance?

A: Yes. The LFJ600301PID is ROHS3 compliant and is appropriate for applications with RoHS requirements. The LJ600301PR is not RoHS compliant.
