Substitute Part Grouping Explanation

Substitution for the 1825CC154MAT9A is based on strict equivalence of the following critical parameters:

• Capacitance Value: 0.15 µF (exact match required)
• Voltage Rating: 630V (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package Designation: 1825 (4564 Metric) (exact match required for PCB footprint compatibility)
• Mounting Technology: Surface Mount MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Compliance Standards: ROHS3 Compliant, REACH Unaffected (must be maintained)
• Moisture Sensitivity: MSL 1 (exact match required)

The tolerance specification may vary between substitute parts provided that the substitute maintains or improves upon the electrical performance characteristics. Packaging format (Tape & Reel versus bulk) does not affect electrical or mechanical compatibility and is a procurement consideration only.

Parameter Comparison

Engineering Selection Recommendations

The 1825CC154KAT1A is a direct substitute for the 1825CC154MAT9A. Both parts are manufactured by KYOCERA AVX and maintain identical electrical specifications, mechanical dimensions, and compliance certifications. The substitute part features a tighter capacitance tolerance of ±10% compared to the original ±20%, which represents an improvement in component precision without any degradation of performance.

Both parts are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications. The identical operating temperature range, voltage rating, and package designation confirm full PCB-level compatibility. Selection between these parts may be based on procurement availability, packaging format requirements (Tape & Reel versus bulk), or tolerance specifications appropriate to the application circuit design.

Frequently Asked Questions (FAQ)

Q: Can 1825CC154KAT1A replace 1825CC154MAT9A in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance values, voltage ratings, temperature coefficients, package dimensions, and mounting specifications. The substitute has a tighter tolerance specification, which does not create compatibility issues.

Q: What is the difference between these two part numbers?

A: The primary difference is the capacitance tolerance: 1825CC154MAT9A has ±20% tolerance, while 1825CC154KAT1A has ±10% tolerance. Both parts are otherwise identical in electrical performance and physical specifications.

Q: Are there packaging differences between these parts?

A: The main part (1825CC154MAT9A) is supplied in standard packaging, while the substitute (1825CC154KAT1A) is supplied in Tape & Reel format. This is a procurement and handling consideration only and does not affect electrical or mechanical compatibility on the PCB.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) ratings. They are suitable for the same regulatory environments and applications.

Q: Can I use 1825CC154KAT1A if my design specifies 1825CC154MAT9A?

A: Yes, without design modification. The substitute meets or exceeds all electrical and mechanical requirements. The tighter tolerance of the substitute may provide improved circuit performance in applications sensitive to capacitance variation.

Q: Are both parts currently available?

A: Both parts are listed as active products in current production. Inventory availability should be confirmed with your component supplier.
