Key Parameters

Substitute Part Grouping Explanation

The LFH600302PID qualifies as a direct substitute based on the following matching 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: Screw Terminal, Pressure Plate (identical)
• Compatible Fuse Classes: Class H(K), Class R (identical)

The primary difference between these parts is the mounting configuration: the LH600302PR uses chassis mount, while the LFH600302PID 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 LFH600302PID is the direct electrical equivalent to the LH600302PR. Both parts maintain identical current, voltage, circuit count, and fuse compatibility specifications. Selection between these parts depends on installation requirements:

• LH600302PR: Use only when chassis mount configuration is mandatory and existing inventory is available. This part is obsolete and should not be specified for new designs.
• LFH600302PID: Preferred for all applications where DIN rail mounting is feasible. This part is active in production and meets ROHS3 compliance requirements, making it suitable for new installations and long-term availability.

For applications requiring chassis mount configuration, the LFH600302PID can be adapted through appropriate mechanical mounting hardware if the electrical specifications are the primary concern.

Frequently Asked Questions (FAQ)

Q: Can the LFH600302PID replace the LH600302PR in existing systems?

A: Yes, electrically and functionally. Both parts accept identical fuse types, operate at the same voltage and current ratings, and provide equivalent circuit protection. The difference is mounting style: chassis mount versus DIN rail. Physical installation method must be evaluated for your specific enclosure design.

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

A: Yes. Both blocks accommodate 0.813" diameter by 5" length Class H(K) and Class R cartridge fuses. Fuse selection depends only on the circuit protection requirements, not on which block is used.

Q: What is the significance of the RoHS compliance difference?

A: The LH600302PR is RoHS non-compliant, while the LFH600302PID meets ROHS3 standards. For new designs, regulatory environments, or procurement policies requiring RoHS compliance, the LFH600302PID is the appropriate choice.

Q: Why is the LH600302PR listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The LFH600302PID represents the active product line continuation with equivalent electrical performance and modern compliance certifications.

Q: Can I use these blocks interchangeably in a multi-circuit protection system?

A: Yes, provided the mounting configuration of your enclosure accommodates the specific block type. Both blocks provide identical 2-circuit protection at 30 A, 600V with the same termination and fuse compatibility.
