Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825CC472MAT9A are qualified based on the following criteria:

• Identical Capacitance: 4700 pF nominal value maintained across all substitutes
• Identical Temperature Coefficient: X7R dielectric ensures stable capacitance across the operating temperature range (-55°C ~ 125°C)
• Identical Package / Case: 1825 (4564 Metric) form factor ensures mechanical and PCB layout compatibility
• Identical Physical Dimensions: 0.177" L x 0.252" W x 0.100" max thickness preserves mounting and thermal characteristics
• Identical Mounting Type: Surface Mount, MLCC technology maintained
• Enhanced Voltage Rating: Substitute parts feature higher rated voltages (2500V or 3000V) compared to the original 630V specification
• Improved Tolerance: Substitute parts offer ±10% tolerance compared to the original ±20% tolerance
• Compliance Equivalence: All substitutes maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating

The substitution logic permits higher voltage-rated components as direct replacements in applications where the original 630V specification is adequate, as higher-rated devices operate within the same thermal and mechanical envelope while providing enhanced design margin.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with full ROHS3 compliance and REACH unaffected designation, ensuring regulatory compliance across current and future procurement cycles. The 1825CC472MAT9A original specification is suitable for applications with 630V maximum operating voltage. The 1825HC472KAT1A (3000V rated) and 1825WC472KAT1A (2500V rated) substitutes provide enhanced voltage margin for designs requiring higher transient voltage protection or operating in elevated voltage environments, while maintaining identical mechanical footprint and thermal characteristics. Selection between substitutes depends on application voltage requirements and design margin specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1825HC472KAT1A or 1825WC472KAT1A be used as direct replacements for the 1825CC472MAT9A?

A: Yes. Both substitutes maintain identical capacitance (4700 pF), temperature coefficient (X7R), package dimensions (1825 / 4564 Metric), and operating temperature range (-55°C ~ 125°C). The higher voltage ratings (3000V and 2500V respectively) are compatible with applications designed for 630V operation.

Q: What is the primary difference between the substitute parts?

A: The 1825HC472KAT1A is rated for 3000V (3kV), while the 1825WC472KAT1A is rated for 2500V (2.5kV). Both offer improved tolerance (±10% versus ±20%) compared to the original part. Selection depends on application voltage requirements and available design margin.

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

A: No. All three parts share identical physical dimensions (0.177" L x 0.252" W x 0.100" max thickness), package type (1825 / 4564 Metric), and surface-mount MLCC mounting technology. PCB layout and assembly processes require no modification.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's regulatory status.

Q: What is the tolerance difference, and does it affect circuit performance?

A: The original 1825CC472MAT9A carries ±20% tolerance, while both substitutes offer ±10% tolerance. Tighter tolerance may improve circuit stability in applications sensitive to capacitance variation, though both specifications are suitable for general-purpose high-voltage applications.
