1825SA102MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1825SA102MAT1A is a 1000 pF ceramic capacitor rated at 1500V (1.5kV) with C0G/NP0 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 temperature ranges from -55°C to 125°C. The part is currently active in production with 691 pieces available in inventory. Substitute parts are identified when design requirements allow for higher voltage ratings, improved tolerance specifications, or alternative packaging configurations while maintaining the same capacitance value and core electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825SA102MAT1A are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 1000 pF (exact match required)
• Temperature Coefficient: C0G, NP0 (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Package / Case: 1825 (4564 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or higher than 1500V
• Tolerance: May be equal to or tighter than ±20%
• Thickness: May vary within component physical constraints
• Packaging Format: May differ (bulk vs. Tape & Reel)

The identified substitute parts (1825GA102JAT1A and 1825GA102KAT1A) both feature upgraded voltage ratings of 2000V (2kV), providing enhanced design margin for high-voltage applications while maintaining all other core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (1825GA102JAT1A and 1825GA102KAT1A) are direct functional replacements for the 1825SA102MAT1A in applications where the circuit design permits higher voltage ratings. The primary distinction between the two substitutes is tolerance specification: 1825GA102JAT1A offers ±5% tolerance, while 1825GA102KAT1A provides ±10% tolerance.

Selection between these substitutes should be based on tolerance requirements of the specific application. Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical operating temperature ranges. The increased thickness (2.20mm vs. 1.80mm) of the substitute parts must be verified against PCB assembly clearance constraints and reflow profile compatibility.

All three parts are currently in active production status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 1825GA102JAT1A or 1825GA102KAT1A be used as direct replacements for 1825SA102MAT1A?

A: Yes, both substitute parts are direct functional replacements. They maintain identical capacitance (1000 pF), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), package type (1825), and mounting configuration (surface mount MLCC). The higher voltage rating (2000V vs. 1500V) provides additional design margin and does not create compatibility issues in circuits designed for 1500V operation.

Q: What is the difference between 1825GA102JAT1A and 1825GA102KAT1A?

A: The primary difference is tolerance specification. 1825GA102JAT1A is rated at ±5% tolerance, while 1825GA102KAT1A is rated at ±10% tolerance. Both share identical voltage ratings (2000V), capacitance (1000 pF), and all other electrical and mechanical parameters. Selection depends on the tolerance requirement of the application circuit.

Q: Will the increased thickness of substitute parts affect PCB assembly?

A: The substitute parts have a maximum thickness of 2.20mm compared to 1.80mm for the main part. This 0.40mm difference must be evaluated against PCB design clearances, component placement density, and reflow oven profile compatibility. Verify that the increased height does not interfere with adjacent components or assembly equipment.

Q: Are all three parts RoHS compliant?

A: Yes, all three parts (1825SA102MAT1A, 1825GA102JAT1A, and 1825GA102KAT1A) are ROHS3 compliant with unlimited moisture sensitivity (MSL 1), making them suitable for applications with RoHS requirements.

Q: What packaging formats are available?

A: The main part (1825SA102MAT1A) is available in standard packaging. Both substitute parts (1825GA102JAT1A and 1825GA102KAT1A) are supplied in Tape & Reel (TR) format. Verify packaging compatibility with your procurement and assembly processes.
