1812AC822MATBE Equivalent & Substitute Parts

Part Overview

The 1812AC822MATBE is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 8200 pF, rated for 1000V (1kV), and featuring X7R temperature coefficient characteristics. This component is classified as an Active product with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The 1812 (4532 Metric) surface-mount package makes it suitable for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Substitute parts are identified when equivalent electrical performance can be maintained while meeting or exceeding the original specifications, particularly in voltage rating, capacitance tolerance, and physical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The 1812GC822KAT1A qualifies as a direct substitute based on the following criteria:

Maintained Electrical Parameters:

• Identical capacitance value: 8200 pF
• Identical temperature coefficient: X7R
• Identical operating temperature range: -55°C to 125°C
• Identical package designation: 1812 (4532 Metric)
• Identical mounting type: Surface Mount, MLCC

Enhanced Specifications:

• Voltage rating upgraded from 1000V to 2000V (2kV)
• Tolerance improved from ±20% to ±10%

Compliance Alignment:

• RoHS3 Compliant (matching original)
• Moisture Sensitivity Level 1 (matching original)
• REACH Unaffected status (matching original)

The substitute part maintains full backward compatibility while providing superior voltage margin and tighter capacitance tolerance, making it suitable for applications where the original 1812AC822MATBE is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812AC822MATBE and 1812GC822KAT1A are Active products with full RoHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current and future applications. The 1812GC822KAT1A provides enhanced design margin through doubled voltage rating (2kV versus 1kV) and improved capacitance tolerance (±10% versus ±20%), while maintaining identical electrical performance in the core application parameters of capacitance value and temperature coefficient. The physical footprint remains compatible for PCB layout purposes, though the increased thickness (2.80mm versus 1.80mm) must be verified against available board clearance. Selection between these parts should be based on circuit voltage requirements, tolerance specifications, and available vertical space in the assembly.

Frequently Asked Questions (FAQ)

Q: Can the 1812GC822KAT1A be used as a direct replacement for the 1812AC822MATBE?

A: Yes. Both parts share identical capacitance (8200 pF), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and 1812 package footprint. The substitute provides enhanced voltage rating and tighter tolerance.

Q: What is the primary difference between these two parts?

A: The 1812GC822KAT1A is rated for 2000V (2kV) with ±10% tolerance, while the 1812AC822MATBE is rated for 1000V (1kV) with ±20% tolerance. Both maintain identical capacitance and temperature characteristics.

Q: Will the increased thickness of the substitute part affect PCB assembly?

A: The 1812GC822KAT1A has a maximum thickness of 2.80mm compared to 1.80mm for the original part. Verify available clearance above the component location on the PCB before substitution.
