1825SC102KAT1A Equivalent & Substitute Parts

Part Overview

The 1825SC102KAT1A is a 1000 pF ceramic capacitor rated at 1500V (1.5kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 1825 (4564 Metric) surface mount package. This component is active and in production, with 1023 units currently in stock. The part is ROHS3 compliant and suitable for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C.

Substitute parts are identified when design requirements allow for higher voltage ratings or alternative temperature coefficient characteristics while maintaining identical capacitance, tolerance, package dimensions, and mounting specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825SC102KAT1A is determined by the following mandatory parameters:

• Capacitance: Must equal 1000 pF
• Tolerance: Must equal ±10%
• Package / Case: Must equal 1825 (4564 Metric)
• Mounting Type: Must equal Surface Mount, MLCC
• Size / Dimension: Must equal 0.177" L x 0.252" W (4.50mm x 6.40mm)
• Operating Temperature Range: Must equal -55°C ~ 125°C
• Manufacturer: KYOCERA AVX

Substitute parts may differ in:

• Voltage - Rated: Higher voltage ratings are acceptable (1500V minimum requirement)
• Temperature Coefficient: Alternative coefficients (C0G/NP0 or X7R) are acceptable
• Thickness (Max): Variation within mechanical constraints is acceptable

Two substitute parts meet these criteria, both offering higher voltage ratings while maintaining all other critical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating, matching the regulatory and environmental requirements of the main part.

1825GA102KAT1A provides a 2kV voltage rating with C0G/NP0 temperature coefficient. This substitute is suitable for applications requiring superior temperature stability and higher voltage margin. The reduced thickness (0.087" vs 0.100") may be advantageous in space-constrained designs.

1825GC102KAT1A provides a 2kV voltage rating while maintaining the X7R temperature coefficient of the original part. This substitute offers the highest inventory availability (2556 units) and identical thickness specification, making it the most direct upgrade path for designs requiring increased voltage headroom without temperature coefficient modification.

Selection between substitutes depends on whether the application benefits from C0G/NP0 stability characteristics or requires continuity with the original X7R specification.

Frequently Asked Questions (FAQ)

Q: Can 1825GA102KAT1A or 1825GC102KAT1A be used as direct replacements for 1825SC102KAT1A?

A: Both parts are direct substitutes. They maintain identical capacitance (1000 pF), tolerance (±10%), package dimensions (1825/4564 Metric), and operating temperature range (-55°C to 125°C). The higher voltage ratings (2kV vs 1.5kV) provide additional design margin and are compatible with circuits designed for the original part.

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

A: C0G/NP0 provides superior temperature stability with minimal capacitance variation across the operating range. X7R allows greater capacitance variation but is suitable for general-purpose applications. The 1825GA102KAT1A uses C0G/NP0, while both the original part and 1825GC102KAT1A use X7R.

Q: Does the thickness difference between 1825GA102KAT1A (0.087") and the original part (0.100") affect PCB layout?

A: The 1825GA102KAT1A is thinner and will not interfere with designs accommodating the original thickness. Verify that your PCB assembly process and component placement equipment support the reduced height specification.

Q: Are all three parts ROHS3 compliant?

A: Yes. The main part 1825SC102KAT1A and both substitutes (1825GA102KAT1A and 1825GC102KAT1A) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Which substitute should I select for maximum inventory availability?

A: The 1825GC102KAT1A has the highest inventory level at 2556 units, compared to 1145 units for 1825GA102KAT1A and 1023 units for the original part.
