Key Parameters

Substitute Part Grouping Explanation

Substitution of the CCMR01.6T is determined by strict equivalence across the following critical parameters:

• Current Rating: 1.6A (exact match required)
• Voltage Ratings: 600 VAC and 250 VDC (exact match required)
• Fuse Class: CC (exact match required)
• Physical Package: 5AG, 10mm x 38mm Midget cartridge (exact match required)
• Response Characteristic: Slow Blow (exact match required)
• Approval Certifications: CE and UL (maintained)
• RoHS Compliance: ROHS3 Compliant (maintained)

The CCMR01.6TXP meets all substitution criteria as a direct equivalent manufactured by the same supplier with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CCMR01.6TXP is the direct substitute for the obsolete CCMR01.6T. Both components are manufactured by Littelfuse Inc. and maintain identical electrical ratings, mechanical dimensions, and safety certifications. The CCMR01.6TXP carries active product status, ensuring continued availability and supply chain support. Both parts comply with ROHS3 requirements and hold CE and UL approvals, meeting regulatory and compliance standards for motor protection applications. Selection of the CCMR01.6TXP eliminates obsolescence risk while preserving full functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CCMR01.6TXP be used as a direct replacement for the CCMR01.6T?

A: Yes. The CCMR01.6TXP is electrically and mechanically identical to the CCMR01.6T. Both components share the same current rating (1.6A), voltage ratings (600 VAC / 250 VDC), fuse class (CC), physical dimensions (10mm x 38mm), and response characteristic (Slow Blow). The primary difference is product status: CCMR01.6T is obsolete while CCMR01.6TXP is active.

Q: Are there any differences in certifications or compliance between these parts?

A: No. Both the CCMR01.6T and CCMR01.6TXP hold identical CE and UL approvals and are ROHS3 compliant. Regulatory and safety certifications are maintained across both part numbers.

Q: What is the physical package specification for these fuses?

A: Both parts use the 5AG package format with dimensions of 10mm x 38mm (Midget cartridge). The physical specification is 0.406" diameter by 1.500" length (10.30mm x 38.10mm). These fuses require a compatible cartridge holder for installation.

Q: What is the breaking capacity of these fuses?

A: Both the CCMR01.6T and CCMR01.6TXP have a breaking capacity of 300kA at rated AC voltage (600 VAC) and 20kA at rated DC voltage (250 VDC).

Q: Why is the CCMR01.6T listed as obsolete?

A: The CCMR01.6T has been discontinued by the manufacturer. The CCMR01.6TXP represents the active equivalent part for continued procurement and system support.
