1825SC103MAT9A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1825SC103MAT9A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 10000 pF and rated voltage of 1500V (1.5kV). This surface-mount multilayer ceramic capacitor (MLCC) features X7R temperature coefficient characteristics and is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent capacitance and package dimensions are maintained while allowing for higher voltage ratings or improved tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825SC103MAT9A are qualified based on the following criteria:

• Capacitance: Must remain 10000 pF (no deviation permitted)
• Package / Case: Must be 1825 (4564 Metric) with identical physical dimensions
• Temperature Coefficient: Must be X7R for consistent thermal stability
• Operating Temperature Range: Must maintain -55°C ~ 125°C specification
• Mounting Type: Must be Surface Mount, MLCC
• Voltage Rating: May be equal to or higher than 1500V
• Tolerance: May be equal to or tighter than ±20%
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The identified substitutes (1825GC103KAT1A and 1825HC103KAT1A) maintain all core electrical and mechanical parameters while offering upgraded voltage ratings (2kV and 3kV respectively) and improved tolerance specifications (±10%).

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing and storage processes.

The 1825SC103MAT9A serves as the baseline specification for 1500V applications. The 1825GC103KAT1A provides a 2kV-rated alternative with improved ±10% tolerance, suitable for circuits requiring higher voltage margin while maintaining the same physical footprint. The 1825HC103KAT1A offers the highest voltage rating at 3kV with equivalent ±10% tolerance, appropriate for applications demanding maximum voltage headroom within the 1825 package envelope.

Selection between these parts depends on circuit voltage requirements and tolerance specifications. All substitutes are electrically and mechanically interchangeable within their respective voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can 1825GC103KAT1A or 1825HC103KAT1A be used as direct replacements for 1825SC103MAT9A?

A: Yes. Both substitute parts maintain identical capacitance (10000 pF), package dimensions (1825/4564 Metric), temperature coefficient (X7R), and operating temperature range (-55°C ~ 125°C). The higher voltage ratings (2kV and 3kV) are backward-compatible with 1500V circuit requirements.

Q: What is the difference between the three parts?

A: The primary differences are voltage rating and tolerance. The 1825SC103MAT9A is rated for 1500V with ±20% tolerance. The 1825GC103KAT1A is rated for 2000V with ±10% tolerance. The 1825HC103KAT1A is rated for 3000V with ±10% tolerance. All other electrical and mechanical specifications remain identical.

Q: Are there packaging differences between these parts?

A: No. All three parts use the 1825 (4564 Metric) package with identical physical dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm) and maximum thickness of 0.100" (2.54mm). Both the main part and substitutes are surface-mount MLCCs suitable for automated assembly.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 with HTSUS code 8532.24.0020. All maintain MSL 1 (unlimited) moisture sensitivity level.

Q: Which substitute should I select for a new design?

A: Selection depends on your circuit's voltage requirements. For 1500V maximum operating voltage, any of the three parts is suitable. For circuits with higher voltage margins, 1825GC103KAT1A (2kV) or 1825HC103KAT1A (3kV) provide additional safety margin. The ±10% tolerance of the substitute parts offers improved capacitance accuracy compared to the ±20% tolerance of the main part.
