KRP-C-5000SP Equivalent & Substitute Parts

Part Overview

The KRP-C-5000SP is a 5kA cartridge fuse manufactured by Eaton - Bussmann Electrical Division, rated for 600 VAC and 300 VDC operation. This slow-blow fuse is designed for bolt mount applications in electrical and industrial systems. The part is currently active in production with 1098 units in stock. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and regulatory approvals align with the original specification, enabling direct replacement in applications where the main part becomes unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KRP-C-5000SP is determined by the following critical parameters:

• Current Rating: 5kA (must match exactly)
• Voltage Rating - AC: 600 VAC (must match exactly)
• Fuse Type: Cartridge (must match exactly)
• Response Time: Slow Blow (must match exactly)
• Mounting Type: Bolt Mount (must match exactly)
• Class: L (must match exactly)
• Package / Case: Cylindrical, Blade Terminal (Bolt) (must match exactly)
• Approval Agency: CE, CSA, UL certifications required

The KLPC5000X from Littelfuse Inc. meets all mandatory electrical and mechanical parameters. While the DC voltage rating differs (480 VDC vs. 300 VDC), this represents an enhanced capability that does not compromise compatibility in applications rated for 300 VDC operation. Physical dimensions vary slightly, and breaking capacity specifications differ; these variations must be evaluated within the specific circuit protection context.

Parameter Comparison

Engineering Selection Recommendations

Both the KRP-C-5000SP and KLPC5000X are active products with full regulatory approvals (CE, CSA, UL). Selection between these parts should be based on:

• Mechanical fit: The KLPC5000X has larger physical dimensions (7.126" Dia x 4.000" L vs. 6.250" Dia x 3.750" L). Verify that the mounting cavity and surrounding circuit board layout accommodate the larger cartridge.
• DC voltage capability: The KLPC5000X supports 480 VDC operation, exceeding the 300 VDC requirement of the KRP-C-5000SP. This enhanced rating does not create incompatibility in 300 VDC circuits.
• Breaking capacity: The KLPC5000X provides higher DC breaking capacity (300kA vs. 100kA), while the KRP-C-5000SP provides higher AC breaking capacity (300kA vs. 200kA). Confirm that the selected part meets the fault current requirements of the application.
• RoHS compliance: Both parts meet RoHS requirements; the KLPC5000X carries ROHS3 certification.

Frequently Asked Questions (FAQ)

Q: Can the KLPC5000X replace the KRP-C-5000SP in a 300 VDC application?

A: Yes. The KLPC5000X is rated for 480 VDC operation, which exceeds the 300 VDC requirement. The higher voltage rating does not compromise performance in lower-voltage circuits.

Q: Are there physical mounting differences between these parts?

A: Yes. The KLPC5000X is larger (7.126" Dia x 4.000" L) compared to the KRP-C-5000SP (6.250" Dia x 3.750" L). Verify that the fuse holder and mounting cavity can accommodate the larger dimensions before substitution.

Q: Do both parts carry the same regulatory approvals?

A: Yes. Both the KRP-C-5000SP and KLPC5000X hold CE, CSA, and UL certifications, meeting the same regulatory requirements for electrical and industrial applications.

Q: What is the difference in breaking capacity, and does it matter?

A: The KRP-C-5000SP provides 300kA AC and 100kA DC breaking capacity. The KLPC5000X provides 200kA AC and 300kA DC breaking capacity. Confirm that the selected part meets the maximum fault current expected in the circuit to ensure proper protection.

Q: Are both parts currently available?

A: Yes. The KRP-C-5000SP has 1098 units in stock, and the KLPC5000X has 809 units in stock, both listed as active products.
