Substitute Part Grouping Explanation

Substitution eligibility for the 1825CC154MAT12 is determined by strict equivalence in the following critical parameters:

• Capacitance Value: Must be 0.15 µF (no deviation permitted)
• Voltage Rating: Must be 630V or higher (equal or superior rating acceptable)
• Temperature Coefficient: Must be X7R (ensures equivalent temperature stability)
• Package / Case: Must be 1825 (4564 Metric) (ensures mechanical and electrical compatibility)
• Mounting Type: Must be Surface Mount, MLCC (ensures assembly process compatibility)
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Compliance Standards: Must maintain RoHS3 compliance and MSL 1 rating

The identified substitute part 1825CC154KAT1A meets all mandatory equivalence criteria. The primary difference is tolerance specification: the substitute offers ±10% tolerance compared to the original ±20% tolerance, representing an upgrade in capacitance accuracy while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825CC154MAT12 and 1825CC154KAT1A are Active products from KYOCERA AVX with identical compliance certifications (RoHS3, REACH Unaffected). Selection between these parts should be based on tolerance requirements specific to the application circuit:

• 1825CC154MAT12: Select when ±20% capacitance tolerance is acceptable for the circuit design and cost optimization is prioritized.
• 1825CC154KAT1A: Select when tighter ±10% capacitance tolerance is required for improved circuit performance or when stricter component specifications are mandated by design standards.

Both parts are suitable for high-voltage general-purpose applications and maintain equivalent electrical performance across the full operating temperature range. Inventory availability should be evaluated based on project timeline requirements.

Frequently Asked Questions (FAQ)

Q: Can 1825CC154KAT1A replace 1825CC154MAT12 in existing designs?

A: Yes. The substitute part maintains identical capacitance value, voltage rating, temperature coefficient, package dimensions, and mounting type. The tighter tolerance specification (±10% vs ±20%) represents an upgrade in accuracy and does not create compatibility issues.

Q: What is the primary difference between these two parts?

A: The capacitance tolerance specification differs: 1825CC154MAT12 has ±20% tolerance while 1825CC154KAT1A has ±10% tolerance. All other electrical and mechanical parameters are equivalent.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both parts use identical 1825 (4564 Metric) package dimensions and Surface Mount MLCC mounting type, ensuring compatibility with standard reflow soldering processes and pick-and-place equipment.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and requiring no special handling or baking procedures prior to assembly.

Q: Are there any compliance or regulatory differences?

A: No. Both parts maintain RoHS3 compliance and REACH Unaffected status, meeting identical regulatory requirements for electronic component use.
