1812SC822KAT3A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812SC822KAT3A is an 8200 pF ceramic capacitor rated at 1500V (1.5kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production with 937 units in stock and carries ROHS3 compliance and REACH unaffected status. Alternative equivalent parts may be required due to inventory constraints, application voltage upgrades, or supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812SC822KAT3A is determined by the following critical parameters:

• Capacitance Value: Must be 8200 pF
• Tolerance: Must be ±10%
• Temperature Coefficient: Must be X7R
• Package / Case: Must be 1812 (4532 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 4.60mm L × 3.20mm W × 2.80mm Max Thickness
• Moisture Sensitivity Level: Must be MSL 1 or better
• Compliance: Must maintain ROHS3 and REACH unaffected status

The 1812GC822KAT1A qualifies as a direct substitute based on these parameters. While it features an upgraded voltage rating of 2000V (2kV) compared to the original 1500V (1.5kV), all other electrical and mechanical specifications remain identical, making it suitable for applications where higher voltage margin is acceptable or required.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC822KAT3A and 1812GC822KAT1A are active production parts manufactured by KYOCERA AVX with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). The primary distinction is the voltage rating differential: the substitute part provides 2000V (2kV) rating versus the original 1500V (1.5kV).

Selection between these parts should be based on circuit voltage requirements. The 1812GC822KAT1A offers higher voltage margin and is available in greater quantity (4052 units versus 937 units). Both parts maintain identical capacitance, tolerance, temperature coefficient, package dimensions, and thermal operating range, ensuring functional equivalence in applications where the elevated voltage rating does not create design conflicts.

Frequently Asked Questions (FAQ)

Q: Can the 1812GC822KAT1A replace the 1812SC822KAT3A in all applications?

A: The 1812GC822KAT1A is electrically and mechanically compatible with the 1812SC822KAT3A for applications operating at or below 1500V. The higher 2000V rating of the substitute part does not create incompatibility. Verify that the elevated voltage rating does not conflict with circuit design specifications or component selection criteria.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1812 (4532 Metric) package with identical dimensions: 4.60mm length, 3.20mm width, and 2.80mm maximum thickness. PCB footprints and assembly processes are interchangeable.

Q: What is the difference in packaging between these parts?

A: The 1812SC822KAT3A is supplied in standard packaging, while the 1812GC822KAT1A is supplied in Tape & Reel (TR) format. Both are surface-mount compatible; packaging selection depends on assembly equipment and volume requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1812SC822KAT3A and 1812GC822KAT1A are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Is the capacitance tolerance identical?

A: Yes. Both parts maintain ±10% capacitance tolerance and X7R temperature coefficient, ensuring equivalent performance across the -55°C to 125°C operating temperature range.
