Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825SC102KAT3A are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 1000 pF
• Tolerance: ±10%
• Package / Case: 1825 (4564 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Voltage Rating: Equal to or greater than 1500V
• Temperature Coefficient: X7R or C0G/NP0 (alternative dielectric materials with equivalent performance characteristics)
• Physical Thickness: Within component envelope constraints

The identified substitutes maintain identical electrical performance at the specified capacitance and tolerance while offering enhanced voltage ratings (2000V / 2kV) and alternative temperature coefficient options. All substitutes are manufactured by KYOCERA AVX and retain Active product status with full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

1825GA102KAT1A (C0G/NP0 Dielectric, 2kV Rating)

This substitute provides a 500V voltage margin increase over the primary part while utilizing C0G/NP0 temperature coefficient. C0G/NP0 dielectrics exhibit superior temperature stability and lower capacitance drift across the operating range compared to X7R. Physical thickness is reduced to 0.087" (2.20mm), providing design flexibility for space-constrained applications. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are maintained. Inventory availability is 1145 units.

1825GC102KAT1A (X7R Dielectric, 2kV Rating)

This substitute maintains the X7R temperature coefficient of the primary part while providing a 500V voltage margin increase to 2000V. Physical thickness remains at 0.100" (2.54mm), matching the original specification. X7R dielectric characteristics are preserved for applications requiring consistent capacitance performance across the full operating temperature range. All compliance certifications are maintained. Inventory availability is 2556 units.

Both substitutes are manufactured by KYOCERA AVX with Active product status and are suitable for direct replacement in applications where the enhanced voltage rating does not conflict with circuit design constraints.

Frequently Asked Questions (FAQ)

Q: Can 1825GA102KAT1A or 1825GC102KAT1A be used as direct replacements for 1825SC102KAT3A?

A: Yes. Both substitutes maintain identical capacitance (1000 pF), tolerance (±10%), package (1825 / 4564 Metric), and operating temperature range (-55°C ~ 125°C). The higher voltage ratings (2000V vs. 1500V) and alternative temperature coefficient options do not prevent direct substitution in circuits designed for the original part.

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

A: X7R dielectrics exhibit capacitance variation of ±15% across the -55°C to 125°C operating range. C0G/NP0 dielectrics provide superior stability with minimal capacitance drift across temperature. Selection depends on application requirements for temperature-dependent capacitance performance.

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

A: No. The reduced thickness of 1825GA102KAT1A is within the 1825 package envelope and does not affect PCB footprint or mounting compatibility. This reduction may provide design advantages in space-constrained applications.

Q: Are all three parts ROHS3 compliant?

A: Yes. The primary part 1825SC102KAT3A and both substitutes (1825GA102KAT1A and 1825GC102KAT1A) are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status.

Q: Which substitute should be selected for maximum voltage margin?

A: Both 1825GA102KAT1A and 1825GC102KAT1A provide identical 2000V voltage ratings, offering 500V margin above the primary part. Selection between these two substitutes should be based on temperature coefficient requirements: C0G/NP0 for superior temperature stability or X7R for consistency with the original design.
