Key Parameters

Substitute Part Grouping Explanation

Substitution of the CCMR02.8T is determined by strict equivalence across the following critical parameters:

• Current Rating: 2.8A (exact match required)
• Voltage Rating: 600 VAC / 300 VDC (exact match required)
• Fuse Class: CC (exact match required)
• Response Time: Slow Blow (exact match required)
• Physical Package: 5AG, 10mm x 38mm Midget cartridge (exact match required)
• Approval Certifications: CE and UL (minimum requirement)

The CCMR02.8TXP meets all substitution criteria as a direct equivalent. The primary distinction is product status: CCMR02.8T is obsolete, while CCMR02.8TXP is active and available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

The CCMR02.8TXP is the direct substitute for the obsolete CCMR02.8T. Both components are manufactured by Littelfuse Inc. and maintain identical electrical and mechanical specifications. The CCMR02.8TXP carries active product status with confirmed inventory availability, making it the appropriate selection for new designs and replacement applications. Both parts maintain CE and UL certifications and ROHS3 compliance, satisfying regulatory requirements for motor protection circuits operating at 600 VAC / 300 VDC with 2.8A current protection.

Frequently Asked Questions (FAQ)

Q: Can CCMR02.8TXP be used as a direct replacement for CCMR02.8T?

A: Yes. The CCMR02.8TXP is electrically and mechanically identical to the CCMR02.8T across all critical parameters: current rating, voltage rating, fuse class, response time, physical dimensions, and breaking capacity. The only difference is product status; CCMR02.8TXP is active production while CCMR02.8T is obsolete.

Q: What determines compatibility between these fuse cartridges?

A: Compatibility is determined by exact equivalence in current rating (2.8A), voltage rating (600 VAC / 300 VDC), fuse class (CC), response time (Slow Blow), and physical package (5AG, 10mm x 38mm). All these parameters must match the application requirements and the fuse holder specifications.

Q: Are there any packaging differences between CCMR02.8T and CCMR02.8TXP?

A: The CCMR02.8T is supplied in standard packaging, while CCMR02.8TXP is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: Do both parts meet the same regulatory certifications?

A: Yes. Both CCMR02.8T and CCMR02.8TXP carry CE and UL approvals and are ROHS3 compliant, meeting the same regulatory requirements for motor protection applications.

Q: Why is the CCMR02.8T listed as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The CCMR02.8TXP remains in active production and serves the same functional requirements, making it the appropriate choice for ongoing applications.
