1825SC102MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1825SC102MAT1A is a 1000 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX with an X7R temperature coefficient and 1500V rated voltage. This surface-mount multilayer ceramic capacitor (MLCC) in 1825 package is designed for general-purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching capacitance, package form factor, and voltage rating specifications while allowing for controlled variations in temperature coefficient and tolerance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1825SC102MAT1A is determined by the following critical parameters:

• Capacitance Value: All substitutes maintain 1000 pF
• Package Form Factor: All substitutes use 1825 (4564 Metric) package
• Mounting Type: All substitutes are surface-mount MLCC
• Operating Temperature Range: All substitutes maintain -55°C ~ 125°C
• Compliance: All substitutes maintain ROHS3 compliance and MSL 1 rating

Substitutes are grouped into two categories based on voltage rating upgrade:

Category 1 - Voltage Upgrade to 2000V (2kV): Parts 1825GA102JAT1A, 1825GA102KAT1A, and 1825GC102KAT1A provide higher voltage rating (2000V vs. 1500V) with variations in temperature coefficient and tolerance specifications.

Tolerance and Temperature Coefficient Variations: Substitutes differ in tolerance (±5%, ±10% vs. ±20%) and temperature coefficient (C0G/NP0 vs. X7R), which are allowable variations for equivalent functionality in general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. The 1825GC102KAT1A is the direct equivalent substitute, maintaining identical temperature coefficient (X7R) and thickness specifications while providing a 500V voltage rating increase to 2000V. This part is recommended for applications where voltage margin improvement is desired without thermal performance trade-offs.

The 1825GA102JAT1A and 1825GA102KAT1A offer C0G/NP0 temperature coefficient with tighter tolerance specifications (±5% and ±10% respectively) and reduced thickness (0.087" vs. 0.100"), providing enhanced stability for precision applications. These parts are suitable for circuits requiring superior temperature stability and tighter capacitance tolerances.

Selection between substitutes depends on application requirements: choose 1825GC102KAT1A for direct thermal performance matching, or 1825GA102JAT1A/1825GA102KAT1A for enhanced voltage margin and temperature stability with tolerance improvements.

Frequently Asked Questions (FAQ)

Q: Can 1825SC102MAT1A be directly replaced with 1825GC102KAT1A?

A: Yes. Both parts share identical capacitance (1000 pF), package (1825), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and physical dimensions. The 1825GC102KAT1A provides higher voltage rating (2000V vs. 1500V) and is a direct functional equivalent.

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

A: X7R provides ±15% capacitance variation across the operating temperature range. C0G/NP0 provides superior stability with minimal capacitance change across temperature. Both maintain the same operating range (-55°C ~ 125°C). C0G/NP0 is preferred for precision applications requiring tighter capacitance tolerance.

Q: Are the substitute parts physically compatible with the original PCB layout?

A: Yes. All substitute parts use the 1825 (4564 Metric) package with identical length (0.177") and width (0.252"). The 1825GA102JAT1A and 1825GA102KAT1A have reduced thickness (0.087" vs. 0.100"), which provides additional clearance and does not create compatibility issues.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All parts, including the main part and substitutes, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.

Q: What is the tolerance difference between the main part and substitutes?

A: The main part 1825SC102MAT1A has ±20% tolerance. Substitutes offer tighter tolerances: 1825GA102JAT1A (±5%), 1825GA102KAT1A (±10%), and 1825GC102KAT1A (±10%). Tighter tolerance provides more precise capacitance values for applications requiring strict component specifications.

Q: Are all parts ROHS3 compliant?

A: Yes. The main part and all substitute parts are ROHS3 compliant with active production status, ensuring regulatory compliance and continued availability.
