KLPC2000X Equivalent & Substitute Parts Reference

Part Overview

The KLPC2000X is a 2kA cartridge fuse manufactured by Littelfuse Inc., rated for 600 VAC and 480 VDC operation. This component is classified as a slow-blow fuse with bolt mount configuration, designed for electrical and industrial applications. The part maintains active product status with 792 units in current inventory stock.

Substitute parts become necessary when supply constraints occur, when alternative sourcing is required for cost optimization, or when system design modifications necessitate compatible alternatives that meet equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KLPC2000X is determined by the following critical parameters:

• Current Rating: Must equal 2kA
• Voltage Rating - AC: Must equal 600 VAC
• Fuse Type: Must be Cartridge
• Response Time: Must be Slow Blow
• Mounting Type: Must be Bolt Mount
• Class: Must be L
• Package / Case: Must be Cylindrical with Blade Terminal (Bolt)
• Physical Dimensions: Must be compatible with 4.600" Dia x 3.752" L envelope

The KRP-C-2000SP qualifies as a substitute part because it matches all critical electrical parameters (2kA current, 600 VAC AC rating, cartridge type, slow-blow response, bolt mount configuration, Class L rating) and maintains compatible physical dimensions. The DC voltage rating difference (300 VDC vs. 480 VDC) represents a constraint that must be evaluated within the specific application context.

Parameter Comparison

Engineering Selection Recommendations

Both the KLPC2000X and KRP-C-2000SP maintain active product status with full regulatory compliance across CE, CSA, and UL certifications. Selection between these components must be based on DC voltage application requirements. The KLPC2000X supports 480 VDC operation, while the KRP-C-2000SP is rated for 300 VDC maximum. For applications operating at or below 300 VDC, the KRP-C-2000SP provides equivalent functionality with identical AC voltage rating, current capacity, and mechanical compatibility. For applications requiring 480 VDC DC operation, the KLPC2000X remains the specified component. Both parts demonstrate equivalent breaking capacity performance at their respective rated voltages and maintain compatible physical envelope dimensions for direct mechanical substitution.

Frequently Asked Questions (FAQ)

Q: Can the KRP-C-2000SP replace the KLPC2000X in all applications?

A: The KRP-C-2000SP is electrically and mechanically compatible for applications operating at 600 VAC and 2kA current rating. However, DC voltage application limits must be verified. If your system operates at 480 VDC, the KLPC2000X is required. If DC operation is at or below 300 VDC, the KRP-C-2000SP is suitable.

Q: Are the physical dimensions identical between these parts?

A: Dimensions are functionally equivalent. The KLPC2000X measures 4.600" Dia x 3.752" L, while the KRP-C-2000SP measures 4.600" Dia x 3.750" L. The 0.002" length difference is within standard mechanical tolerance and does not affect bolt mount installation.

Q: Do both parts carry the same regulatory certifications?

A: Yes. Both the KLPC2000X and KRP-C-2000SP hold CE, CSA, and UL approvals, confirming compliance with applicable electrical safety standards.

Q: What is the difference in breaking capacity between these parts?

A: The KLPC2000X provides 200kA AC and 300kA DC breaking capacity. The KRP-C-2000SP provides 300kA AC and 100kA DC breaking capacity. Breaking capacity selection depends on the fault current levels present in your specific circuit.

Q: Are there packaging differences between the main part and substitute?

A: The KLPC2000X is supplied in box packaging, while the KRP-C-2000SP is supplied in bulk packaging. This affects order quantities and storage considerations but does not impact electrical or mechanical performance.
