1825AC104MAT3A Equivalent & Substitute Parts

Part Overview

The 1825AC104MAT3A is a 0.1 µF ceramic capacitor rated for 1000V (1kV) 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). Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and sourcing options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the 1825AC104MAT3A is determined by strict equivalence in the following parameters:

• Capacitance Value: 0.1 µF (exact match required)
• Voltage Rating: 1000V (1kV) minimum (equal or higher acceptable)
• Temperature Coefficient: X7R (ensures stable performance across operating range)
• Package / Case: 1825 (4564 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount, MLCC (assembly compatibility)
• Operating Temperature Range: -55°C to 125°C (functional equivalence)
• Compliance Standards: ROHS3 Compliant, REACH Unaffected (regulatory alignment)

The substitute part 1825AC104KAT1A meets all these criteria. The primary difference is the tolerance specification (±10% versus ±20%), which represents an upgrade in capacitance accuracy while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825AC104MAT3A and 1825AC104KAT1A are active production parts from KYOCERA AVX with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts is based on tolerance requirements:

• 1825AC104MAT3A: Select when ±20% capacitance tolerance is acceptable for the application.
• 1825AC104KAT1A: Select when tighter ±10% capacitance tolerance is required for improved circuit performance or when inventory availability favors this variant.

Both parts are electrically and mechanically interchangeable in 1825 package footprints. The substitute part offers superior tolerance specification without any compromise to voltage rating, temperature stability, or compliance status.

Frequently Asked Questions (FAQ)

Q: Can 1825AC104KAT1A replace 1825AC104MAT3A in existing designs?

A: Yes. Both parts are identical in capacitance value (0.1 µF), voltage rating (1000V), temperature coefficient (X7R), package (1825), and operating temperature range (-55°C to 125°C). The substitute has tighter tolerance (±10% vs ±20%), making it a direct replacement with improved accuracy.

Q: What is the difference between these two parts?

A: The primary difference is capacitance tolerance. The 1825AC104MAT3A has ±20% tolerance, while the 1825AC104KAT1A has ±10% tolerance. All other electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical?

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

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and have MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should I select for new designs?

A: Selection depends on tolerance requirements. For applications requiring tighter capacitance accuracy, use 1825AC104KAT1A. For general-purpose applications where ±20% tolerance is acceptable, either part is suitable based on availability.
