1825SC153MAT3A\SB Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 1825SC153MAT3A\SB is a 0.015 µF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V operation with X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 1825 package format is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating range. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent capacitance and package geometry are maintained while allowing for higher voltage ratings and improved tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825SC153MAT3A\SB is determined by strict adherence to the following parameters:

Fixed Parameters (Must Match Exactly):

• Capacitance: 0.015 µF
• Package / Case: 1825 (4564 Metric)
• Mounting Type: Surface Mount, MLCC
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C to 125°C
• Physical Dimensions: 4.50mm L × 6.40mm W
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Voltage Rating: May be equal to or higher than 1500V
• Tolerance: May be tighter (lower) than ±20%

The identified substitute parts maintain identical capacitance, package geometry, and environmental specifications while offering enhanced voltage ratings and improved tolerance characteristics. Both substitute parts are manufactured by KYOCERA AVX and retain full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified replacements for the 1825SC153MAT3A\SB based on maintained electrical and mechanical compatibility. Selection between the main part and substitutes depends on circuit voltage requirements:

1825SC153MAT3A\SB is appropriate for applications with maximum operating voltages up to 1500V and where ±20% capacitance tolerance is acceptable.

1825GC153KAT1A provides a 2000V voltage rating with improved ±10% tolerance, suitable for circuits requiring higher voltage margin or tighter capacitance specification within the same package footprint.

1825WC153KAT1A offers the highest voltage rating at 2500V with ±10% tolerance, providing maximum voltage headroom and tolerance performance in the identical 1825 package geometry.

All three parts maintain Active product status, full ROHS3 compliance, and unlimited moisture sensitivity rating. Selection should be based on circuit voltage requirements and tolerance specifications rather than availability or cost considerations alone.

Frequently Asked Questions (FAQ)

Q: Can 1825GC153KAT1A or 1825WC153KAT1A be used as direct replacements for 1825SC153MAT3A\SB?

A: Yes. Both substitute parts maintain identical capacitance (0.015 µF), package geometry (1825 / 4564 Metric), mounting type (Surface Mount MLCC), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The higher voltage ratings (2000V and 2500V respectively) and improved tolerance (±10%) are compatible with any circuit designed for the original 1500V specification.

Q: What is the difference between the two substitute parts?

A: Both 1825GC153KAT1A and 1825WC153KAT1A share identical capacitance, tolerance, and package specifications. The primary difference is voltage rating: 1825GC153KAT1A is rated for 2000V, while 1825WC153KAT1A is rated for 2500V. Selection depends on the maximum voltage requirement of the application.

Q: Are there any physical or mounting differences between these parts?

A: No. All three parts use identical 1825 (4564 Metric) package geometry with dimensions of 4.50mm length × 6.40mm width × 2.54mm maximum thickness. They are all surface-mount MLCCs with identical footprints and mounting requirements.

Q: Do all parts meet the same compliance standards?

A: Yes. The main part and both substitutes are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All maintain MSL 1 (unlimited moisture sensitivity) rating.

Q: What tolerance improvement do the substitute parts offer?

A: The main part 1825SC153MAT3A\SB has ±20% tolerance. Both substitute parts (1825GC153KAT1A and 1825WC153KAT1A) offer ±10% tolerance, representing a 50% reduction in allowable capacitance variation.
