Key Parameters

Substitute Part Grouping Explanation

The LFH600302CID qualifies as a direct substitute based on the following critical parameters:

• Current Rating: 30 A (identical)
• Voltage Rating: 600V (identical)
• Number of Circuits: 2 (identical)
• Fuse Type: Cartridge (identical)
• Fuseholder Type: Block (identical)
• Termination Style: Box Lug (identical)
• Compatible Fuse Classes: Class H(K), Class R (identical)

The primary difference between the main part and substitute is the mounting configuration: the LH600302C uses chassis mount, while the LFH600302CID uses DIN rail mount. This distinction affects physical installation but does not alter electrical compatibility or fuse holder functionality.

Parameter Comparison

Engineering Selection Recommendations

The LFH600302CID is the direct electrical and functional equivalent to the LH600302C. Selection between these parts depends on installation requirements:

• Chassis Mount Requirement: If the original installation uses chassis mount configuration, the LH600302C remains the specified part. However, given its obsolete status, long-term availability is limited.

• DIN Rail Installation: The LFH600302CID is suitable for systems using DIN rail mounting. This part is currently active in production and carries ROHS3 compliance, providing better long-term supply chain stability and regulatory alignment.

• Compliance Consideration: The LFH600302CID meets ROHS3 requirements and is REACH unaffected, making it preferable for new designs or systems requiring modern compliance certifications.

Both parts accept identical fuse types and ratings, ensuring electrical interchangeability when mounting configuration permits.

Frequently Asked Questions (FAQ)

Q: Can the LFH600302CID replace the LH600302C in all applications?

A: Electrical and functional compatibility is complete. Physical installation compatibility depends on whether the system accommodates DIN rail mounting. If the original system requires chassis mount configuration, mechanical adaptation would be necessary.

Q: Are the fuse cartridges interchangeable between these two parts?

A: Yes. Both parts accept Class H(K) and Class R cartridge fuses at 30 A, 600V. Fuse cartridge specifications are identical.

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

A: The LH600302C is obsolete, indicating discontinued production. The LFH600302CID is active, ensuring ongoing availability and support. For new procurements or long-term system planning, the active part is preferable.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical characteristics. Both parts maintain identical electrical ratings and performance specifications.

Q: Are there any termination differences between these parts?

A: No. Both parts use box lug termination, ensuring compatible connection methods in the circuit.
