Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1825CC154MAT1A is determined by the following critical parameters:

• Capacitance Value: Must be 0.15 µF
• Voltage Rating: Must be 630V or higher
• Temperature Coefficient: Must be X7R for stable performance across the operating temperature range
• Package Dimensions: Must be 1825 (4564 Metric) for PCB compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Compliance: Must maintain RoHS3 compliance and MSL 1 rating

The substitute part 1825CC154KAT1A meets all these criteria with an improved tolerance specification (±10% versus ±20%), making it a direct electrical and mechanical equivalent with enhanced precision characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825CC154MAT1A and 1825CC154KAT1A are active production parts from KYOCERA AVX with identical electrical ratings, package specifications, and compliance certifications. The primary distinction is capacitance tolerance: the MAT1A variant carries ±20% tolerance, while the KAT1A variant offers ±10% tolerance. Selection between these parts depends on circuit requirements for capacitance accuracy. Both parts maintain full RoHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical thermal performance across the -55°C to 125°C operating range. PCB layout and assembly processes are interchangeable due to matching 1825 package dimensions and surface-mount configuration.

Frequently Asked Questions (FAQ)

Q: Can 1825CC154KAT1A replace 1825CC154MAT1A in existing designs?

A: Yes. Both parts share identical capacitance value (0.15 µF), voltage rating (630V), temperature coefficient (X7R), package dimensions (1825/4564 Metric), and mounting type (Surface Mount, MLCC). The KAT1A variant provides tighter tolerance (±10% versus ±20%), making it suitable for applications requiring higher capacitance precision.

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

A: No. Both parts are ROHS3 compliant, carry MSL 1 (unlimited moisture sensitivity), and are REACH unaffected. Compliance certifications and environmental ratings are identical.

Q: What is the significance of the tolerance difference?

A: Tolerance defines the acceptable deviation from the nominal 0.15 µF capacitance value. The MAT1A allows ±20% deviation (0.12 µF to 0.18 µF), while the KAT1A allows ±10% deviation (0.135 µF to 0.165 µF). Applications requiring tighter capacitance control should specify the KAT1A variant.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1825 (4564 Metric) package with dimensions of 4.50mm length, 6.40mm width, and 2.54mm maximum thickness. PCB footprints and assembly processes are identical.

Q: Can these parts be used interchangeably in high-voltage applications?

A: Yes. Both parts are rated for 630V operation with X7R temperature stability across -55°C to 125°C. High-voltage performance characteristics are equivalent.
