LH250601C Equivalent & Substitute Parts

Part Overview

The LH250601C is a cartridge fuse block rated for 60 A at 250V with single-circuit chassis mount configuration, manufactured by Littelfuse Inc. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and component procurement. The primary functional requirement is to provide a secure mounting and connection point for Class H(K) and Class R cartridge fuses in 250V electrical systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LH250601C is determined by electrical and mechanical compatibility across the following critical parameters:

• Current Rating: Must match 60 A specification
• Voltage Rating: Must match 250V specification
• Fuse Type & Size: Must accommodate cartridge fuses at 0.813" Dia x 3" L (20.65mm x 76.2mm)
• Number of Circuits: Must provide single-circuit configuration
• Fuseholder Type: Must be block-type fuseholder
• Compatible Fuse Classes: Must support Class H(K) and Class R fuses
• Termination Style: Must provide box lug termination

The LFH250601CID meets all electrical requirements for direct substitution. The primary difference is mounting configuration: the substitute uses DIN rail mounting instead of chassis mount, which represents a mechanical variation rather than an electrical incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The LFH250601CID is the direct electrical equivalent to the LH250601C. Both components share identical current, voltage, fuse type, and circuit specifications. Selection between these parts depends on system integration requirements:

LH250601C is suitable only for legacy systems already configured for chassis mount installation and where RoHS compliance is not a procurement requirement.

LFH250601CID is the preferred selection for new designs and system upgrades due to active product status and ROHS3 compliance. The DIN rail mounting configuration requires mechanical integration adjustment but provides superior long-term component availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can LFH250601CID replace LH250601C in existing installations?

A: Electrical compatibility is complete. Mechanical compatibility depends on available mounting space and infrastructure. Chassis mount and DIN rail configurations require different physical mounting arrangements. System integration assessment is necessary before installation.

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

A: Yes. Both components accept identical cartridge fuses at 0.813" Dia x 3" L (20.65mm x 76.2mm) and support Class H(K) and Class R fuse types.

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

A: LH250601C is RoHS non-compliant, while LFH250601CID is ROHS3 compliant. For new procurement and systems subject to RoHS regulations, LFH250601CID is the required selection.

Q: Are there any electrical performance differences between these parts?

A: No. Both components are rated for 60 A at 250V with identical electrical specifications and fuse compatibility.

Q: What is the inventory status for these parts?

A: LH250601C has 1006 units in stock (obsolete status). LFH250601CID has 759 units in stock (active status). Active product status indicates continued manufacturing support for LFH250601CID.
