1825GC102MAT3A\SB Equivalent & Substitute Parts

Part Overview

The 1825GC102MAT3A\SB is a 1000 pF, 2000V (2kV) ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient characteristics. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across the 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 based on matching critical electrical parameters: capacitance value, voltage rating, package size, and temperature coefficient classification.

Substitute Part Grouping Explanation

Substitute parts for the 1825GC102MAT3A\SB are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 1000 pF
• Voltage Rating: 2000V (2kV)
• Package / Case: 1825 (4564 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C to 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Tolerance: ±20% (main part) to ±10% (substitute parts) — tighter tolerance is acceptable
• Temperature Coefficient: X7R (main part) or C0G/NP0 (substitute) — both provide stable capacitance across operating range
• Packaging Format: Bulk or Tape & Reel (TR)
• Thickness: Minor variations within mechanical constraints

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are direct functional equivalents to the 1825GC102MAT3A\SB based on electrical and mechanical compatibility:

1825GC102KAT1A — Identical temperature coefficient (X7R) with improved tolerance specification (±10% versus ±20%). This part provides the closest electrical match and is available in Tape & Reel packaging format. Recommended for applications where tighter capacitance tolerance is beneficial.

1825GA102KAT1A — Offers C0G/NP0 temperature coefficient, which provides superior capacitance stability and lower dissipation factor compared to X7R. Thickness is reduced to 0.087" (2.20mm) versus 0.100" (2.54mm) on the main part, allowing for more compact board designs. Available in Tape & Reel packaging. Recommended for applications requiring enhanced temperature stability or space-constrained layouts.

All three parts carry ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and active product status. Selection between substitute parts depends on specific application requirements for temperature coefficient performance and physical height constraints.

Frequently Asked Questions (FAQ)

Q: Can 1825GC102KAT1A replace 1825GC102MAT3A\SB directly?

A: Yes. Both parts share identical capacitance (1000 pF), voltage rating (2000V), temperature coefficient (X7R), package size (1825), and operating temperature range (-55°C to 125°C). The substitute has tighter tolerance (±10% versus ±20%), which is compatible with the original specification.

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 superior stability with minimal capacitance change across temperature. Both are acceptable for this 1000 pF, 2kV application; selection depends on circuit requirements for temperature stability.

Q: Does the thickness difference between 1825GC102MAT3A\SB (0.100") and 1825GA102KAT1A (0.087") affect compatibility?

A: No. The reduced thickness of 1825GA102KAT1A is compatible with standard 1825 package footprints and does not affect electrical performance. This variation allows for more compact board designs where height is constrained.

Q: Are all three parts available in the same packaging format?

A: The main part 1825GC102MAT3A\SB is supplied in bulk packaging. Both substitute parts (1825GC102KAT1A and 1825GA102KAT1A) are available in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity). All are classified as active products by KYOCERA AVX.
