Key Parameters

Substitute Part Grouping Explanation

Substitution of the CCMR07.5T is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 7.5A (exact match required)
• Voltage Rating: 600 VAC / 250 VDC (exact match required)
• Response Time: Slow Blow (exact match required)
• Fuse Class: CC (exact match required)
• Physical Package: 5AG, 10mm x 38mm Midget cartridge (exact match required)
• Breaking Capacity: 300kA AC / 20kA DC (exact match required)
• Approval Certifications: CE, CSA, UL (exact match required)

The CCMR07.5TXP meets all substitution criteria as a direct equivalent. The primary distinction is product status: CCMR07.5T is obsolete, while CCMR07.5TXP is active, and packaging differs (standard vs. bulk).

Parameter Comparison

Engineering Selection Recommendations

The CCMR07.5TXP is the direct functional equivalent for CCMR07.5T applications. Both parts maintain identical electrical specifications, mechanical dimensions, and regulatory certifications. Selection of CCMR07.5TXP is supported by its active product status, ensuring continued availability and supply chain reliability. Both parts are ROHS3 compliant and carry equivalent approval certifications (CE, CSA, UL), confirming suitability for motor protection circuits operating at 600 VAC / 250 VDC with 7.5A load requirements.

Frequently Asked Questions (FAQ)

Q: Can CCMR07.5TXP be used as a direct replacement for CCMR07.5T?

A: Yes. Both parts are identical in electrical rating (7.5A, 600 VAC / 250 VDC), response time (slow blow), fuse class (CC), physical dimensions (5AG, 10mm x 38mm), and breaking capacity (300kA AC / 20kA DC). The CCMR07.5TXP is the active production equivalent.

Q: What is the difference between CCMR07.5T and CCMR07.5TXP?

A: The primary differences are product status and packaging. CCMR07.5T is obsolete with standard packaging, while CCMR07.5TXP is active with bulk packaging. All electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts use the same 5AG cartridge form factor (10mm x 38mm), require the same holder, and operate within identical voltage and current parameters. Direct substitution is mechanically and electrically compatible.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both CCMR07.5T and CCMR07.5TXP carry CE, CSA, and UL certifications and are ROHS3 compliant, confirming equivalent regulatory compliance for motor protection applications.

Q: What is the breaking capacity of these fuses?

A: Both parts have a breaking capacity of 300kA at rated AC voltage (600 VAC) and 20kA at rated DC voltage (250 VDC), meeting CC class requirements for motor protection circuits.
