CCMR03.2T Equivalent & Substitute Parts

Part Overview

The CCMR03.2T is a 3.2A cartridge fuse manufactured by Littelfuse Inc., rated for 600 VAC and 300 VDC operation. Designed for motor protection applications, this slow-blow fuse features a 5AG (10mm x 38mm midget) form factor and requires a compatible holder for installation. The part is currently classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CCMR03.2T is determined by strict equivalence across the following critical parameters:

• Current Rating: 3.2A (exact match required)
• Voltage Rating: 600 VAC / 300 VDC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Response Time: Slow Blow (exact match required)
• Class: CC (exact match required)
• Package / Case: 5AG, 10mm x 38mm Midget (exact match required)
• Physical Dimensions: 0.406" Dia x 1.500" L (exact match required)
• Approval Certifications: CE, UL (must be maintained)
• RoHS Compliance: ROHS3 Compliant (must be maintained)

The CCMR03.2TXP meets all substitution criteria as an active product variant within the same POWR-GARD® / POWR-PRO® CCMR series, differing only in packaging configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

The CCMR03.2TXP is the direct active equivalent for the obsolete CCMR03.2T. Both parts maintain identical electrical and mechanical specifications, including current rating, voltage ratings, response characteristics, and physical form factor. The CCMR03.2TXP carries active product status and maintains all required certifications (CE, UL) and RoHS3 compliance. The only distinction is packaging configuration (bulk versus standard), which does not affect functional performance or compatibility with existing holder assemblies. Selection of the CCMR03.2TXP ensures continuity of supply and compliance with current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the CCMR03.2TXP be used as a direct replacement for the CCMR03.2T?

A: Yes. The CCMR03.2TXP is electrically and mechanically identical to the CCMR03.2T. Both parts share the same current rating (3.2A), voltage ratings (600 VAC / 300 VDC), response time (slow blow), class (CC), and physical dimensions (5AG, 10mm x 38mm). The CCMR03.2TXP is compatible with all holders designed for the CCMR03.2T.

Q: What is the difference between the CCMR03.2T and CCMR03.2TXP?

A: The primary difference is product status and packaging. The CCMR03.2T is obsolete, while the CCMR03.2TXP is active. The CCMR03.2TXP is supplied in bulk packaging, whereas the CCMR03.2T uses standard packaging. Functional and electrical characteristics are identical.

Q: Are both parts certified to the same standards?

A: Yes. Both the CCMR03.2T and CCMR03.2TXP carry CE and UL approvals and are ROHS3 compliant. Regulatory compliance is maintained across both variants.

Q: Does packaging configuration affect fuse performance?

A: No. Packaging configuration (bulk versus standard) does not affect electrical performance, response characteristics, or mechanical compatibility. The fuse element and operational specifications remain unchanged.

Q: What holder types are compatible with these fuses?

A: Both the CCMR03.2T and CCMR03.2TXP require a compatible cartridge fuse holder designed for 5AG (10mm x 38mm midget) form factor cartridges. Holder compatibility is determined by physical dimensions and mounting type, not by packaging configuration.
