Key Parameters

Substitute Part Grouping Explanation

The LFJ600302PID is classified as a direct manufacturer substitute for the LJ600302PR based on strict equivalence of the following critical parameters:

• Voltage Rating: 600V (identical)
• Current Rating: 30 A (identical)
• Fuse Size: 0.813" Dia x 2.25" L (identical mechanical dimensions)
• Number of Circuits: 2 (identical)
• Fuse Type: Cartridge (identical)
• Fuseholder Type: Block (identical)
• Mounting Type: DIN Rail (identical)
• Termination Style: Screw Terminal, Pressure Plate (identical)
• For Use With: Class J Fuses (identical compatibility)

These parameters define the functional and physical interchangeability of the substitute part within the same application context.

Parameter Comparison

Engineering Selection Recommendations

The LFJ600302PID is the appropriate substitute for the obsolete LJ600302PR. Both components maintain identical electrical ratings (600V, 30A) and mechanical specifications (fuse size, DIN rail mounting, 2-circuit configuration). The LFJ600302PID offers the advantage of active product status, ensuring continued availability and supply chain support. Additionally, the LFJ600302PID meets ROHS3 compliance requirements, whereas the LJ600302PR is non-compliant. For new installations or component replacement in systems requiring regulatory compliance, the LFJ600302PID is the specified choice.

Frequently Asked Questions (FAQ)

Q: Can the LFJ600302PID directly replace the LJ600302PR in existing installations?

A: Yes. Both components share identical voltage ratings (600V), current ratings (30A), fuse sizes (0.813" Dia x 2.25" L), circuit configurations (2-circuit), and termination styles (Screw Terminal, Pressure Plate). DIN rail mounting and Class J fuse compatibility are equivalent.

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

A: The LJ600302PR is obsolete, while the LFJ600302PID maintains active product status. The LFJ600302PID also meets ROHS3 compliance standards, whereas the LJ600302PR does not.

Q: Are there packaging differences between the LJ600302PR and LFJ600302PID?

A: The LFJ600302PID is supplied in box packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: What fuse types are compatible with both components?

A: Both the LJ600302PR and LFJ600302PID are designed for use with Class J fuses and support the 0.813" Dia x 2.25" L cartridge format.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both components have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions.
