Substitute Part Grouping Explanation

Substitution eligibility for the 1825CC154MAT1A\SB is determined by strict equivalence in the following critical parameters:

• Capacitance Value: Must be 0.15 µF (no deviation)
• Voltage Rating: Must be 630V or higher
• Temperature Coefficient: Must be X7R (ensures stable performance across -55°C to 125°C)
• Package / Case: Must be 1825 (4564 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 4.50mm L × 6.40mm W footprint
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The identified substitute part 1825CC154KAT1A meets all these criteria. The primary difference is tolerance specification (±10% versus ±20%), which represents an upgrade in capacitance accuracy while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825CC154MAT1A\SB and 1825CC154KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts should be based on tolerance requirements:

• 1825CC154MAT1A\SB is suitable for applications where ±20% capacitance tolerance is acceptable and cost optimization is prioritized.
• 1825CC154KAT1A is suitable for applications requiring tighter capacitance accuracy (±10%) while maintaining identical electrical performance, voltage rating, and thermal stability.

Both parts are directly interchangeable at the PCB footprint level and require no design modifications. The choice between them depends solely on circuit tolerance specifications and procurement availability.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical capacitance (0.15 µF), voltage rating (630V), temperature coefficient (X7R), package (1825), and physical dimensions. The 1825CC154KAT1A offers improved tolerance (±10% versus ±20%) with no design changes required.

Q: What is the difference between these two parts?

A: The primary difference is capacitance tolerance. The 1825CC154MAT1A\SB has ±20% tolerance, while the 1825CC154KAT1A has ±10% tolerance. All other electrical and mechanical specifications are identical.

Q: Are both parts suitable for high-voltage applications?

A: Yes. Both parts are rated for 630V operation and feature X7R temperature coefficient, providing stable performance across -55°C to 125°C. They are classified as high-voltage ceramic capacitors suitable for general-purpose applications.

Q: Do these parts require different PCB footprints?

A: No. Both parts use the 1825 (4564 Metric) package with identical physical dimensions (4.50mm L × 6.40mm W). They are mechanically and electrically interchangeable without PCB modifications.

Q: Are both parts RoHS compliant?

A: Yes. Both 1825CC154MAT1A\SB and 1825CC154KAT1A are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity), meeting current environmental and regulatory standards.

Q: Which part should I select for my application?

A: Selection depends on your circuit's tolerance requirements. If ±20% tolerance is acceptable, either part is suitable. If tighter capacitance accuracy is required, the 1825CC154KAT1A with ±10% tolerance is the appropriate choice.
