KYOCERA AVX 1825GC102MAT3A Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825GC102MAT3A is a 1000 pF ceramic capacitor rated for 2000V (2kV) with X7R temperature coefficient, designed for high-voltage general-purpose applications. This surface-mount multilayer ceramic capacitor (MLCC) in 1825 (4564 Metric) package is ROHS3 compliant and currently active in production. Equivalent and substitute parts may be required due to inventory availability, tolerance specifications, or packaging format preferences while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825GC102MAT3A are qualified based on the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Capacitance: 1000 pF (exact match required)
• Voltage Rating: 2000V (2kV) minimum (exact match required)
• Package / Case: 1825 (4564 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

Allowable Variation Parameters:

• Tolerance: ±20% to ±10% (tighter tolerance acceptable as upgrade)
• Temperature Coefficient: X7R or C0G/NP0 (both acceptable for general-purpose applications at rated voltage)
• Packaging Format: Bulk or Tape & Reel (TR) (format variation acceptable)
• Thickness: Up to 0.100" (2.54mm) maximum (thinner acceptable)

Two substitute parts meet these criteria with improved tolerance specifications while maintaining all critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are direct functional equivalents to the 1825GC102MAT3A with enhanced specifications:

1825GC102KAT1A maintains identical X7R temperature coefficient while upgrading tolerance from ±20% to ±10%. This part is available in Tape & Reel packaging and offers improved capacitance accuracy for applications requiring tighter tolerance control. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are identical to the main part.

1825GA102KAT1A provides C0G/NP0 temperature coefficient with ±10% tolerance and reduced thickness (0.087" vs. 0.100"). This configuration offers superior temperature stability and is suitable for applications where minimal capacitance drift across the operating temperature range is required. Physical profile reduction may benefit space-constrained designs. All compliance certifications match the main part.

Both substitutes are active production parts with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between them depends on application requirements for temperature coefficient stability and physical thickness constraints.

Frequently Asked Questions (FAQ)

Q: Can 1825GC102KAT1A replace 1825GC102MAT3A directly? A: Yes. Both parts share identical capacitance (1000 pF), voltage rating (2000V), temperature coefficient (X7R), package (1825), and operating temperature range (-55°C to 125°C). The substitute offers improved ±10% tolerance versus ±20%, with identical physical dimensions and compliance certifications.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R provides ±15% capacitance change across the operating temperature range. C0G/NP0 provides ±30 ppm/°C (approximately ±0.3% across -55°C to 125°C), offering superior temperature stability. Both are acceptable for this 1000 pF, 2000V application; selection depends on circuit requirements for capacitance stability.

Q: Does the thickness difference between 1825GC102MAT3A (0.100") and 1825GA102KAT1A (0.087") affect compatibility? A: No. The thinner profile of 1825GA102KAT1A is mechanically compatible with standard 1825 footprints. The reduced thickness may provide benefits in space-constrained PCB designs without affecting electrical performance or mounting reliability.

Q: Are packaging format differences (Bulk vs. Tape & Reel) electrically significant? A: No. Bulk and Tape & Reel packaging contain identical components. Format selection is based on assembly process requirements and inventory management. Both formats meet identical electrical and compliance specifications.

Q: Can these parts be used interchangeably in high-voltage applications? A: Yes. All three parts are rated for 2000V (2kV) with identical voltage specifications, operating temperature ranges, and RoHS3 compliance. They are electrically and mechanically interchangeable for high-voltage general-purpose applications within the specified parameters.

Q: What does ROHS3 Compliant and REACH Unaffected mean? A: ROHS3 Compliant indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. REACH Unaffected indicates the part is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) restrictions. All three parts meet these compliance standards.
