KYOCERA AVX 1825SC102MAT3A Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825SC102MAT3A is a 1000 pF, 1500V (1.5kV) ceramic capacitor with X7R temperature coefficient in 1825 (4564 Metric) surface mount package. This high-voltage MLCC is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant, REACH unaffected, and maintains unlimited moisture sensitivity level (MSL 1). Finding equivalent or substitute parts may be necessary due to inventory constraints, design optimization requirements, or voltage margin considerations in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1825SC102MAT3A is determined by the following critical parameters:

Fixed Requirements (Non-Negotiable):

• Capacitance: 1000 pF
• 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:

• Voltage - Rated: Equal to or greater than 1500V
• Tolerance: Equal to or tighter than ±20%
• Temperature Coefficient: X7R or C0G/NP0 (both acceptable for general-purpose applications)

The substitute parts listed below meet or exceed the electrical and mechanical specifications of the main part while maintaining full compatibility with the 1825 package footprint and surface mount assembly process.

Parameter Comparison

Engineering Selection Recommendations

1825GC102KAT1A (X7R, 2kV): This substitute maintains the X7R temperature coefficient of the main part while providing a 33% increase in voltage rating (2000V vs. 1500V). Tolerance is improved to ±10%. The maximum thickness remains at 0.100" (2.54mm), ensuring identical PCB assembly compatibility. This part is suitable for applications requiring enhanced voltage margin while preserving X7R dielectric characteristics.

1825GA102KAT1A (C0G/NP0, 2kV): This substitute provides the highest voltage rating at 2000V with C0G/NP0 temperature coefficient, delivering superior temperature stability and lower capacitance drift compared to X7R. Tolerance is ±10%. The maximum thickness is reduced to 0.087" (2.20mm), which may provide additional PCB design flexibility. This part is suitable for precision applications where temperature stability is critical.

Both substitute parts are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (Unlimited) rating. All three parts are manufactured by KYOCERA AVX and share identical footprint dimensions, enabling direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can 1825GC102KAT1A or 1825GA102KAT1A be used as direct replacements for 1825SC102MAT3A?

A: Yes. Both substitute parts maintain the same 1000 pF capacitance, 1825 package footprint, and surface mount assembly requirements. The substitutes provide equal or superior voltage ratings and improved tolerance specifications, making them electrically and mechanically compatible with the original part.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with minimal capacitance drift across temperature. The 1825SC102MAT3A and 1825GC102KAT1A use X7R; the 1825GA102KAT1A uses C0G/NP0. Selection depends on application requirements for temperature stability.

Q: Does the reduced thickness of 1825GA102KAT1A (0.087" vs. 0.100") affect PCB assembly?

A: No. The reduced thickness of 1825GA102KAT1A is within standard MLCC manufacturing tolerances and does not affect surface mount assembly processes or PCB layout compatibility. Both thickness values are acceptable for the 1825 package footprint.

Q: Are all three parts ROHS3 compliant?

A: Yes. The main part 1825SC102MAT3A and both substitute parts 1825GC102KAT1A and 1825GA102KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the advantage of the ±10% tolerance in substitute parts compared to ±20% in the main part?

A: The ±10% tolerance in 1825GC102KAT1A and 1825GA102KAT1A provides tighter capacitance control, reducing variation in circuit performance. This is beneficial for applications requiring more precise capacitance values within the design specification.

Q: Can I use 1825GA102KAT1A in place of 1825GC102KAT1A?

A: Yes. Both parts share identical capacitance, voltage rating, package, and operating temperature range. The primary difference is temperature coefficient (C0G/NP0 vs. X7R). Selection between them depends on whether the application requires the superior temperature stability of C0G/NP0 or the broader availability of X7R.
