CCMR010.T Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The CCMR010.T is a 10A cartridge fuse manufactured by Littelfuse Inc., rated for 600 VAC and 250 VDC operation. This component is classified as obsolete, necessitating identification of active equivalent parts for continued system support and procurement. The fuse is designed for motor protection applications and requires a compatible holder for installation. Substitute parts must maintain identical electrical ratings and mechanical compatibility to ensure proper circuit protection without system redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CCMR010.T is determined by the following critical parameters:

Primary Compatibility Criteria:

• Current Rating: 10A (exact match required)
• Voltage Rating - AC: 600 VAC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Class: CC (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5AG, 10mm x 38mm (Midget) (exact match required)
• Breaking Capacity: 200kA AC, 20kA DC (exact match required)

Secondary Compatibility Criteria:

• Voltage Rating - DC: 250 VDC or higher (equal or greater rating acceptable)
• Mounting Type: Requires Holder (exact match required)
• Approval Agency: CE and/or UL certification required

The CCMR010.T has two identified substitutes: CCMR010.TXP (direct manufacturer equivalent) and LP-CC-10 (cross-manufacturer alternative). Both maintain identical AC voltage, current, fuse type, class, and mechanical dimensions. The DC voltage rating difference in LP-CC-10 (150 VDC vs. 250 VDC) represents a lower rating and requires application-specific evaluation.

Parameter Comparison

Engineering Selection Recommendations

CCMR010.TXP (Littelfuse Inc.) is the primary substitute for CCMR010.T. This part maintains identical electrical specifications, mechanical dimensions, and certifications while offering active product status with significantly higher inventory availability (100,099 units). The transition from obsolete to active status ensures long-term procurement reliability. Packaging differs (bulk vs. standard), but electrical and mechanical compatibility is complete.

LP-CC-10 (Eaton - Bussmann Electrical Division) serves as a cross-manufacturer alternative. This part maintains all critical parameters including current rating, AC voltage, fuse class, response time, and breaking capacity. The DC voltage rating is reduced from 250 VDC to 150 VDC, which may limit applicability in systems requiring the full 250 VDC rating. Mechanical dimensions show minor variation (0.394" Dia x 1.496" L vs. 0.406" Dia x 1.500" L), remaining within 5AG cartridge specifications. Certifications include CE, CSA, and UR, providing broader regional compliance than the original part.

Selection between CCMR010.TXP and LP-CC-10 depends on DC voltage requirements and regional certification needs. For applications operating at or below 150 VDC, LP-CC-10 provides cross-manufacturer redundancy. For applications requiring the full 250 VDC rating, CCMR010.TXP is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can CCMR010.TXP be used as a direct replacement for CCMR010.T?

A: Yes. CCMR010.TXP maintains identical current rating (10A), AC voltage (600 VAC), DC voltage (250 VDC), fuse type (cartridge), class (CC), response time (slow blow), mechanical dimensions (0.406" Dia x 1.500" L), and breaking capacity (200kA AC, 20kA DC). Both parts require the same holder and provide equivalent circuit protection.

Q: What is the difference between CCMR010.T and CCMR010.TXP?

A: The primary difference is product status. CCMR010.T is obsolete, while CCMR010.TXP is active with substantially higher inventory availability. Electrical and mechanical specifications are identical. Packaging differs (standard vs. bulk), but this does not affect component performance or compatibility.

Q: Can LP-CC-10 replace CCMR010.T in all applications?

A: LP-CC-10 is compatible with applications operating at 150 VDC or lower. The original CCMR010.T is rated for 250 VDC. If the system operates exclusively at or below 150 VDC, LP-CC-10 provides a valid substitute. If the system requires the full 250 VDC rating, CCMR010.TXP is the appropriate selection.

Q: Are there mechanical compatibility concerns with LP-CC-10?

A: LP-CC-10 dimensions are 0.394" Dia x 1.496" L, compared to CCMR010.T at 0.406" Dia x 1.500" L. Both conform to 5AG cartridge specifications and fit standard CC-class holders. Minor dimensional variation is within acceptable tolerance for this fuse class and does not affect holder compatibility.

Q: What certifications apply to each substitute?

A: CCMR010.T and CCMR010.TXP carry CE and UL certifications. LP-CC-10 carries CE, CSA, and UR certifications. Selection based on regional requirements: UL for North America, CSA for Canada, UR for additional regional compliance.

Q: Is inventory availability a factor in substitute selection?

A: CCMR010.TXP offers 100,099 units in stock, compared to 1,220 units for the obsolete CCMR010.T. For procurement planning, CCMR010.TXP provides superior long-term availability and supply chain stability.
