Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KRP-C-601SP is determined by the following critical parameters:

• Current Rating: 601A (exact match required)
• Voltage Rating - AC: 600 VAC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Mounting Type: Bolt Mount (exact match required)
• Class: L (exact match required)
• Package / Case: Cylindrical, Blade Terminal (Bolt) (exact match required)
• Physical Dimensions: Compatible within tolerance (2.500" Dia x 3.750" L nominal)
• Approval Agencies: CE, CSA, UL certification required

The KLPC601.X from Littelfuse Inc. qualifies as a substitute based on matching current rating, AC voltage rating, fuse type, mounting configuration, class designation, and package style. Dimensional compatibility is confirmed within acceptable tolerance. Both parts carry equivalent regulatory certifications (CE, CSA, UL).

Parameter Comparison

Engineering Selection Recommendations

Both the KRP-C-601SP and KLPC601.X maintain Active product status with full regulatory compliance (CE, CSA, UL certifications). The primary distinction between these parts is the DC voltage rating: the KRP-C-601SP is rated for 300 VDC, while the KLPC601.X is rated for 480 VDC. The KLPC601.X provides higher DC voltage capability, making it suitable for applications requiring extended DC operating range. Both parts are RoHS compliant and dimensionally compatible within standard manufacturing tolerances. Selection between these parts depends on the specific DC voltage requirement of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can KLPC601.X replace KRP-C-601SP in all applications?

A: The KLPC601.X is electrically and mechanically compatible for applications operating at 600 VAC and up to 480 VDC. If the application operates exclusively at 300 VDC or lower, both parts are functionally equivalent. If DC voltage exceeds 300 VDC, the KLPC601.X is required.

Q: Are the physical dimensions identical?

A: Dimensions are nominally equivalent: KRP-C-601SP measures 2.500" Dia x 3.750" L, while KLPC601.X measures 2.500" Dia x 3.752" L. The 0.002" length difference is within standard manufacturing tolerance and does not affect mechanical fit in bolt mount applications.

Q: Do both parts carry the same certifications?

A: Yes. Both the KRP-C-601SP and KLPC601.X are certified by CE, CSA, and UL, meeting equivalent regulatory requirements for industrial and electrical applications.

Q: What is the difference in breaking capacity?

A: The KRP-C-601SP has a breaking capacity of 300kA AC and 100kA DC. The KLPC601.X has a breaking capacity of 200kA AC and 300kA DC. Breaking capacity specifications are provided by the manufacturer and should be evaluated against circuit requirements.

Q: Are both parts available in the same packaging?

A: The KRP-C-601SP is supplied in Bulk packaging, while the KLPC601.X is supplied in Box packaging. This difference affects inventory management and handling but does not impact electrical or mechanical performance.
