LT602001C Equivalent & Substitute Parts

Part Overview

The LT602001C is a cartridge fuse block rated for 200 A at 600V, designed for single-circuit chassis mount applications with Class T fuses. This component is classified as obsolete, making identification of compatible alternatives essential for system maintenance and component replacement in existing installations.

The primary reason for identifying substitute parts is the obsolete status of the original LT602001C. Active alternatives with identical electrical ratings and mechanical compatibility enable continued system operation without redesign.

Key Parameters

Substitute Part Grouping Explanation

The LFT602001CS qualifies as a direct substitute based on the following critical parameters:

• Electrical Compatibility: Identical current rating (200 A) and voltage rating (600V)
• Mechanical Compatibility: Identical fuse size (1.063" Dia x 3.25" L / 27mm x 82.55mm) and cartridge fuse type
• Functional Compatibility: Single-circuit block configuration with Class T fuse support and box lug termination
• Electrical Interface: Matching termination style ensures direct connection compatibility

The primary difference is the mounting type: LT602001C uses chassis mount, while LFT602001CS uses DIN rail mount. This distinction affects installation method but does not alter electrical or fuse compatibility.

Parameter Comparison

Engineering Selection Recommendations

The LFT602001CS is the direct electrical and mechanical equivalent for the obsolete LT602001C. Both components support identical fuse specifications, current capacity, and voltage ratings.

Selection between these parts depends on installation requirements:

• Chassis Mount Requirement: If the original mounting configuration must be preserved, the LT602001C remains the only option, though availability is limited to existing inventory.
• DIN Rail Installation: The LFT602001CS provides an active, in-stock alternative suitable for DIN rail mounting applications.
• Regulatory Compliance: The LFT602001CS meets ROHS3 compliance standards, whereas the LT602001C does not. For new installations or systems with compliance requirements, the LFT602001CS is the preferred choice.

Both components are manufactured by Littelfuse Inc. and carry identical ECCN classification (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the LFT602001CS replace the LT602001C in an existing installation?

A: Electrical and fuse compatibility are identical. Substitution is feasible if the mounting infrastructure can accommodate DIN rail mounting. If the original system requires chassis mount configuration, physical modification may be necessary.

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

A: Yes. Both blocks accept the same Class T cartridge fuses with dimensions 1.063" Dia x 3.25" L (27mm x 82.55mm). Fuse selection is independent of the block model.

Q: What is the difference in termination between these parts?

A: Both parts use box lug termination. The electrical interface is identical; the difference lies only in mounting method.

Q: Does the LFT602001CS meet current regulatory standards?

A: The LFT602001CS is ROHS3 compliant and REACH unaffected. The LT602001C is RoHS non-compliant. For applications requiring regulatory compliance, the LFT602001CS is the appropriate selection.

Q: Is the LT602001C still available?

A: The LT602001C is classified as obsolete. Current inventory is limited to existing stock (1018 pcs reported). The LFT602001CS is active and maintains current production status with 995 pcs in stock.
