LH602001C Equivalent & Substitute Parts

Part Overview

The LH602001C is a cartridge fuse block rated for 200 A at 600V with single-circuit configuration and chassis mount orientation. This component is classified as obsolete, making identification of equivalent substitute parts essential for system maintenance and component replacement in existing installations. The part accommodates Class H(K) and Class R fuses in a cartridge format with box lug termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LH602001C is determined by the following critical parameters that must remain constant:

• Current Rating: 200 A
• Voltage Rating: 600V
• Fuse Type: Cartridge
• Fuseholder Type: Block
• Number of Circuits: 1
• Compatible Fuse Classes: Class H(K), Class R
• Termination Style: Box Lug

The LFH602001C qualifies as a direct substitute based on matching all critical electrical and functional parameters. The primary difference is the mounting configuration: the LFH602001C uses DIN Rail mounting instead of chassis mount. This represents a mechanical variation that allows the substitute to function in applications where DIN Rail mounting is available or preferred, while maintaining identical electrical performance and fuse compatibility.

Engineering Selection Recommendations

The LFH602001C is the direct electrical equivalent to the LH602001C. Selection between these parts depends on mounting infrastructure availability:

• Use LFH602001C when DIN Rail mounting is available in the target installation. This part carries Active product status and meets ROHS3 compliance requirements, making it suitable for new designs and ongoing procurement.
• The LH602001C remains applicable only in existing installations where chassis mount configuration is already established and component replacement is required for maintenance purposes.

Both parts maintain identical electrical ratings, fuse compatibility, and termination characteristics. The substitution is valid from an electrical and functional standpoint; mounting configuration is the sole mechanical consideration.

Frequently Asked Questions (FAQ)

Q: Can the LFH602001C replace the LH602001C in any application?

A: The LFH602001C is electrically equivalent and functionally compatible. Substitution is valid when the installation supports DIN Rail mounting. If the original installation uses chassis mount exclusively, physical mounting modification may be required.

Q: Are the fuse cartridge dimensions identical between these parts?

A: The LH602001C specifies fuse dimensions of 2.094" Dia x 9.626" L (53.2mm x 244.5mm). The LFH602001C does not specify fuse dimensions in the provided data. Both parts accept Class H(K) and Class R cartridge fuses with identical electrical ratings.

Q: What is the difference in RoHS compliance between these parts?

A: The LH602001C is RoHS non-compliant. The LFH602001C meets ROHS3 compliance standards. For applications subject to RoHS regulatory requirements, the LFH602001C is the appropriate selection.

Q: Are both parts rated for the same voltage and current?

A: Yes. Both the LH602001C and LFH602001C are rated for 200 A at 600V with single-circuit configuration and box lug termination.

Q: What is the inventory status of these parts?

A: The LH602001C has 890 pieces in stock with obsolete status. The LFH602001C has 1043 pieces in stock with active product status, indicating ongoing availability and manufacturer support.
