1812AC153MATME Equivalent & Substitute Parts

Part Overview

The 1812AC153MATME is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 0.015 µF capacitance with 1000V (1kV) voltage rating and X7R temperature coefficient. This component 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 with 943 units currently in stock. Substitute parts are identified when design requirements allow for higher voltage ratings, improved tolerance specifications, or alternative packaging configurations while maintaining the same capacitance value and physical footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812AC153MATME is determined by the following critical parameters:

• Capacitance Value: Must remain 0.015 µF (no deviation permitted)
• Package / Case: Must be 1812 (4532 Metric) to ensure mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Temperature Coefficient: Must be X7R to maintain temperature stability characteristics
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Compliance Standards: Must maintain ROHS3 compliance and REACH Unaffected status

The 1812SC153KAT1A qualifies as a substitute because it maintains identical capacitance, package footprint, mounting type, and temperature coefficient. The substitute offers an upgraded voltage rating (1500V vs. 1000V) and improved tolerance (±10% vs. ±20%), making it suitable for applications where higher voltage margins or tighter capacitance tolerance are beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812AC153MATME and 1812SC153KAT1A maintain Active product status and full compliance with ROHS3 and REACH requirements. The 1812SC153KAT1A provides enhanced electrical performance through higher voltage rating and tighter tolerance specification while preserving identical capacitance and thermal characteristics. Selection between these parts depends on circuit voltage requirements and tolerance specifications. The substitute part's increased thickness (2.80mm vs. 2.20mm) must be evaluated against available PCB assembly clearance. Both parts are suitable for general-purpose applications within their respective voltage and tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1812SC153KAT1A replace the 1812AC153MATME in all applications?

A: The 1812SC153KAT1A is electrically compatible as a direct substitute when circuit design permits the higher voltage rating and improved tolerance. Physical clearance must be verified due to increased thickness (2.80mm vs. 2.20mm).

Q: What is the significance of the ±10% tolerance improvement in the substitute part?

A: The 1812SC153KAT1A offers ±10% tolerance compared to ±20% in the main part, resulting in tighter capacitance accuracy. This is beneficial for applications with strict capacitance specifications but is not required for general-purpose use.

Q: Are there any packaging differences between these parts?

A: Both parts use identical 1812 (4532 Metric) package footprints and Surface Mount, MLCC mounting type. The substitute part has a maximum thickness of 2.80mm compared to 2.20mm for the main part. Tape & Reel packaging is available for the substitute part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1812AC153MATME and 1812SC153KAT1A are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Q: What is the voltage derating consideration when using the 1812SC153KAT1A?

A: The 1812SC153KAT1A provides 500V additional voltage margin (1500V vs. 1000V rating). This higher rating allows for greater safety margin in high-voltage applications but does not alter the capacitance or temperature stability characteristics.
