KYOCERA AVX 1825CC104MAT9A Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825CC104MAT9A is a 0.1 µF ceramic capacitor rated for 630V with X7R temperature coefficient, designed for high-voltage general-purpose applications. This surface-mount multilayer ceramic capacitor (MLCC) in 1825 (4564 Metric) package is actively produced and ROHS3 compliant. Substitute parts are identified to address packaging format availability, tolerance improvements, or voltage rating upgrades while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825CC104MAT9A are qualified based on the following criteria:

Electrical Compatibility:

• Identical capacitance value (0.1 µF)
• Identical temperature coefficient (X7R)
• Identical operating temperature range (-55°C to 125°C)
• Voltage rating equal to or greater than 630V
• Tolerance equal to or better than ±20%

Mechanical Compatibility:

• Identical package / case designation (1825 / 4564 Metric)
• Identical physical dimensions (4.50mm × 6.40mm × 2.54mm max)
• Surface-mount MLCC mounting type

Compliance & Availability:

• Active product status
• ROHS3 compliant
• MSL 1 rating
• REACH unaffected status

All substitute parts meet these criteria and are direct functional replacements.

Parameter Comparison

Engineering Selection Recommendations

1825AC104KAT1A (Upgrade Option): This substitute provides improved tolerance (±10% vs. ±20%) and elevated voltage rating (1000V vs. 630V). Selection is appropriate for applications requiring tighter capacitance tolerance or higher voltage margin. All compliance certifications (ROHS3, REACH unaffected) and MSL rating are identical to the main part.

1825CC104KAT1A (Direct Equivalent): This substitute maintains identical electrical specifications (0.1 µF, ±10% tolerance, 630V rating) and mechanical compatibility. The primary difference is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel). Selection is appropriate when Tape & Reel packaging is required for automated assembly processes. Compliance and MSL ratings are identical.

All substitute parts are active products with confirmed inventory availability and meet the same regulatory and environmental standards as the main part.

Frequently Asked Questions (FAQ)

Q: Can 1825AC104KAT1A replace 1825CC104MAT9A in a 630V circuit? A: Yes. The 1825AC104KAT1A is rated for 1000V, which exceeds the 630V requirement. The identical capacitance (0.1 µF), temperature coefficient (X7R), operating temperature range, and package dimensions ensure functional compatibility. The improved tolerance (±10%) is an additional benefit.

Q: What is the difference between the two substitute parts? A: Both 1825AC104KAT1A and 1825CC104KAT1A share identical electrical specifications (0.1 µF, ±10% tolerance, X7R, -55°C to 125°C). The primary distinction is packaging format: 1825AC104KAT1A is supplied in Cut Tape & Digi-Reel format, while 1825CC104KAT1A is supplied in Tape & Reel format. Select based on your assembly equipment requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. The main part 1825CC104MAT9A and both substitute parts (1825AC104KAT1A and 1825CC104KAT1A) are ROHS3 compliant and REACH unaffected.

Q: Does the ±10% tolerance of substitute parts affect circuit performance compared to the ±20% main part? A: The substitute parts offer tighter tolerance control (±10% vs. ±20%), which reduces capacitance variation. This is beneficial for applications sensitive to capacitance drift and does not introduce incompatibility.

Q: Are the physical dimensions identical across all parts? A: Yes. The main part and both substitute parts use the 1825 (4564 Metric) package with identical dimensions: 4.50mm length × 6.40mm width × 2.54mm maximum thickness. All are surface-mount MLCCs with identical footprints.

Q: What is MSL 1 rating? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. All parts in this comparison carry MSL 1 rating, eliminating moisture-related handling constraints.
