CCMR015.HXP Equivalent & Substitute Parts

Part Overview

The CCMR015.HXP is a 15A cartridge fuse manufactured by Littelfuse, rated for 600 VAC and 500 VDC operation. This slow-blow fuse is designed for motor protection applications and requires a compatible holder for installation. The part is currently active in production with full RoHS3 compliance and CE/UL approval. Substitute parts are identified when equivalent electrical ratings and mechanical compatibility are maintained across the same fuse class and package specification.

Substitute Part Grouping Explanation

Substitution eligibility for the CCMR015.HXP is determined by the following criteria:

• Current Rating: Must be 15A
• AC Voltage Rating: Must be 600 VAC minimum
• Fuse Class: Must be CC class
• Package: Must be 5AG, 10mm x 38mm (Midget)
• Response Time: Must be Slow Blow
• Mounting: Must require holder (same mechanical interface)

The LP-CC-15 manufactured by Eaton - Bussmann Electrical Division meets these primary substitution criteria. The DC voltage rating differs (150 VDC versus 500 VDC on the main part), which represents a reduced capability in DC applications. This difference must be evaluated against the specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CCMR015.HXP and LP-CC-15 are active production parts with full RoHS3 compliance and international regulatory approval. The CCMR015.HXP carries UL and CE certifications, while the LP-CC-15 carries CE, CSA, and UR certifications. Selection between these parts depends on the specific voltage environment and regulatory requirements of the application.

The primary technical difference is the DC voltage rating: the CCMR015.HXP is rated to 500 VDC, while the LP-CC-15 is rated to 150 VDC. In AC-only applications at 600 VAC, both parts are electrically equivalent. In DC or mixed-voltage applications, the voltage rating differential must be considered against circuit requirements.

The CCMR015.HXP provides higher breaking capacity at AC (300kA versus 200kA), which may be relevant in high-fault-current environments. Both parts maintain identical DC breaking capacity at 20kA.

Frequently Asked Questions (FAQ)

Q: Can the LP-CC-15 be used in place of the CCMR015.HXP in all applications?

A: The LP-CC-15 is mechanically and electrically compatible for AC applications at 600 VAC. However, if the circuit operates at DC voltages above 150 VDC, the CCMR015.HXP must be used due to its 500 VDC rating. Verify the actual DC voltage present in your circuit before substitution.

Q: Are the physical dimensions identical between these two parts?

A: Both parts use the 5AG, 10mm x 38mm (Midget) package. Dimensional tolerances differ slightly (CCMR015.HXP: 0.406" Dia x 1.500" L; LP-CC-15: 0.394" Dia x 1.496" L), but both fit standard CC-class cartridge holders designed for this package specification.

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

A: The CCMR015.HXP has a 300kA AC breaking capacity compared to the LP-CC-15's 200kA AC breaking capacity. Breaking capacity indicates the maximum fault current the fuse can safely interrupt. In circuits with fault currents exceeding 200kA AC, the CCMR015.HXP is required. Verify your system's available fault current before selecting a substitute.

Q: Which certifications apply to my region?

A: The CCMR015.HXP carries UL and CE marks. The LP-CC-15 carries CE, CSA, and UR marks. Confirm which certification body has jurisdiction in your market before final part selection.

Q: Can these fuses be used interchangeably in the same holder?

A: Yes, both parts use the same 5AG, 10mm x 38mm (Midget) package and fit standard CC-class cartridge holders. Physical installation is compatible. Electrical compatibility depends on your circuit's voltage and fault current specifications.
