1825CC154MAT3A Equivalent & Substitute Parts

Part Overview

The 1825CC154MAT3A is a 0.15 µF ceramic capacitor rated for 630V with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the 1825CC154MAT3A is determined by strict equivalence in 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)
• Mounting Technology: Surface Mount MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Environmental Compliance: ROHS3 Compliant, MSL 1 (exact match required)

The identified substitute part 1825CC154KAT1A meets all critical electrical and mechanical parameters. The primary difference is the capacitance tolerance specification, which is tighter (±10%) compared to the main part (±20%), representing an upgrade in precision without affecting functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825CC154MAT3A and 1825CC154KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 1825CC154KAT1A represents a direct substitute with identical electrical ratings and mechanical specifications. The tighter capacitance tolerance (±10% versus ±20%) of the substitute part provides enhanced precision without introducing any compatibility concerns. Selection between these parts should be based on tolerance requirements for the specific application and packaging format availability (the substitute is supplied in Tape & Reel format).

Frequently Asked Questions (FAQ)

Q: Can 1825CC154KAT1A replace 1825CC154MAT3A in existing designs? A: Yes. Both parts are electrically and mechanically identical with the same capacitance value (0.15 µF), voltage rating (630V), temperature coefficient (X7R), package size (1825), and operating temperature range (-55°C to 125°C). The substitute has a tighter tolerance specification, which is compatible with applications designed for the original part.

Q: What is the difference between these two part numbers? A: The primary difference is the capacitance tolerance: 1825CC154MAT3A has ±20% tolerance, while 1825CC154KAT1A has ±10% tolerance. Additionally, the substitute part is supplied in Tape & Reel packaging format. All other electrical and mechanical parameters are identical.

Q: Are both parts RoHS compliant? A: Yes. Both 1825CC154MAT3A and 1825CC154KAT1A are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and REACH unaffected status.

Q: Does the package size remain the same? A: Yes. Both parts use the identical 1825 (4564 Metric) package with dimensions of 0.177" L x 0.252" W (4.50mm x 6.40mm) and maximum thickness of 0.100" (2.54mm).

Q: Which part should I select for new designs? A: Selection depends on tolerance requirements and packaging preferences. The 1825CC154KAT1A with ±10% tolerance is suitable for applications requiring tighter capacitance accuracy. Both parts are active in production and available in adequate inventory quantities.
