1825AC104MAT1A Equivalent & Substitute Parts

Part Overview

The 1825AC104MAT1A 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). Substitute parts are identified when equivalent electrical performance can be maintained while accommodating different packaging formats or tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1825AC104MAT1A is determined by strict equivalence in the following critical parameters:

• Capacitance Value: Must be 0.1 µF
• Voltage Rating: Must be 1000V (1kV) minimum
• Temperature Coefficient: Must be X7R
• Package / Case: Must be 1825 (4564 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Compliance: Must maintain ROHS3 and REACH Unaffected status

The substitute part 1825AC104KAT1A meets all critical electrical and mechanical parameters. The primary difference is tolerance specification (±10% versus ±20%) and packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). These variations do not affect functional equivalence for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825AC104MAT1A and 1825AC104KAT1A are active production parts from KYOCERA AVX with identical electrical specifications and physical dimensions. Selection between these parts should be based on:

Tolerance Requirements: The 1825AC104KAT1A offers tighter tolerance (±10%) compared to the main part (±20%). Applications requiring closer capacitance accuracy should specify the substitute part.

Packaging and Supply Chain: The main part is supplied in Tape & Reel format, while the substitute is available in Cut Tape & Digi-Reel® format. Packaging selection depends on assembly equipment compatibility and procurement volume requirements.

Compliance and Regulatory: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, ensuring equivalent regulatory standing for all applications.

Inventory Availability: The substitute part (1330 Pcs in stock) has higher current inventory than the main part (923 Pcs in stock).

Frequently Asked Questions (FAQ)

Q: Can 1825AC104KAT1A be used as a direct replacement for 1825AC104MAT1A?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (0.1 µF), voltage rating (1000V), temperature coefficient (X7R), package dimensions (1825/4564 Metric), and compliance certifications. The substitute offers improved tolerance (±10% versus ±20%).

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) is a continuous reel format suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® provides flexibility for lower-volume or mixed-component orders. Both formats contain the same component; packaging selection depends on assembly line requirements and order quantities.

Q: Does the tighter tolerance of 1825AC104KAT1A affect circuit performance?

A: The ±10% tolerance of the substitute part provides tighter capacitance accuracy compared to the ±20% tolerance of the main part. This may improve circuit performance in applications sensitive to capacitance variation, but both parts meet the same electrical specifications for general-purpose use.

Q: Are both parts suitable for high-voltage applications?

A: Yes. Both the 1825AC104MAT1A and 1825AC104KAT1A are rated for 1000V (1kV) and feature X7R temperature stability across -55°C to 125°C, making them suitable for high-voltage general-purpose applications.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures apply without special moisture control requirements.
