L60060C3C Equivalent & Substitute Parts

Part Overview

The L60060C3C is a cartridge fuse block manufactured by Littelfuse Inc., rated for 60 A at 600V with 3 circuits, designed for DIN rail mounting. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new installations where legacy specifications must be maintained.

The primary reason for identifying substitutes is the discontinued status of the original part number. The LFC600603CID serves as the direct equivalent, offering identical electrical ratings and functional performance while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

The LFC600603CID is classified as a direct manufacturer substitute for the L60060C3C based on the following critical parameters:

• Electrical Compatibility: Both parts maintain identical current rating (60 A) and voltage rating (600V)
• Circuit Configuration: Both feature 3-circuit cartridge fuse block architecture
• Mounting Standard: Both utilize DIN rail mounting, ensuring mechanical compatibility with existing installations
• Termination: Both employ box lug termination style
• Contact Properties: Both use copper alloy contacts with tin finish, ensuring equivalent electrical performance and reliability

The primary distinction between these parts is the fuse cartridge size accommodation and active versus obsolete product status. The LFC600603CID represents the current production equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LFC600603CID is the appropriate substitute for the obsolete L60060C3C based on electrical and mechanical equivalence. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility.

The transition from L60060C3C to LFC600603CID is supported by active product status of the substitute, ensuring long-term availability and supply chain continuity. Both parts are manufactured by Littelfuse Inc., maintaining consistency in design standards and quality assurance protocols.

The difference in fuse cartridge size accommodation (Class CD for L60060C3C versus Class CC/CD for LFC600603CID) reflects design evolution in the product line. The LFC600603CID's broader fuse compatibility range provides enhanced flexibility for system applications.

Frequently Asked Questions (FAQ)

Q: Can the LFC600603CID directly replace the L60060C3C in existing installations?

A: Yes. Both parts share identical electrical ratings (60 A, 600V, 3 circuits), mounting type (DIN rail), and termination style (box lug). The primary consideration is fuse cartridge size compatibility with your system's existing fuse inventory.

Q: What is the difference in fuse cartridge size between these parts?

A: The L60060C3C accommodates Class CD fuses (0.394" Dia x 1.496" L), while the LFC600603CID accommodates Class CC/CD fuses (0.850" Dia x 1.880" L). Verify your system's fuse cartridge specifications before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the L60060C3C and LFC600603CID are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Why is the L60060C3C listed as obsolete?

A: The L60060C3C has been discontinued by Littelfuse Inc. The LFC600603CID represents the current production equivalent with active product status.

Q: Do both parts have the same contact material and finish?

A: Yes. Both parts feature copper alloy contacts with tin finish, ensuring equivalent electrical conductivity and corrosion resistance.
