1812SC822MAT3A\SB Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812SC822MAT3A\SB is an 8200 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V (1.5kV) operation with X7R temperature coefficient characteristics. This Surface Mount MLCC (Multilayer Ceramic Capacitor) in 1812 (4532 Metric) package format is designed for general-purpose high-voltage applications requiring stable capacitance across the -55°C to 125°C operating temperature range. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent capacitance and package geometry must be maintained while accommodating different voltage ratings or tolerance specifications within the same physical footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812SC822MAT3A\SB is determined by strict adherence to the following parameters:

Fixed Parameters (Non-Negotiable):

• Capacitance value: 8200 pF
• Package format: 1812 (4532 Metric)
• Physical dimensions: 4.60mm L × 3.20mm W × 2.80mm Max Thickness
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°C
• Mounting type: Surface Mount, MLCC
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Variable Parameters (Allowed for Substitution):

• Voltage rating: May be equal to or higher than 1500V
• Tolerance: May be tighter (lower) than ±20%
• Packaging format: May differ (e.g., Tape & Reel vs. standard packaging)

The identified substitute part 1812GC822KAT1A maintains all fixed parameters while providing upgraded voltage rating (2000V) and improved tolerance (±10%), making it suitable for applications requiring enhanced voltage margin or tighter capacitance specification within the same physical and thermal envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC822MAT3A\SB and 1812GC822KAT1A are active production parts manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on circuit voltage requirements and tolerance specifications:

The 1812SC822MAT3A\SB is appropriate for applications with maximum operating voltages at or below 1500V where ±20% capacitance tolerance is acceptable.

The 1812GC822KAT1A provides upgraded voltage rating (2000V) and tighter tolerance (±10%), making it suitable for circuits requiring higher voltage margin or more precise capacitance specification. The identical physical footprint and thermal characteristics ensure direct PCB compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can 1812GC822KAT1A be used as a direct replacement for 1812SC822MAT3A\SB?

A: Yes. Both parts share identical capacitance (8200 pF), package format (1812/4532 Metric), physical dimensions, temperature coefficient (X7R), and operating temperature range. The substitute provides higher voltage rating and tighter tolerance, making it electrically compatible for any application designed for the original part.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (1500V vs. 2000V) and tolerance specification (±20% vs. ±10%). The 1812GC822KAT1A offers enhanced voltage margin and improved capacitance accuracy. All other electrical and mechanical parameters remain identical.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use identical 1812 (4532 Metric) package format with matching physical dimensions (4.60mm L × 3.20mm W × 2.80mm Max Thickness). No PCB footprint or layout modifications are required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both 1812SC822MAT3A\SB and 1812GC822KAT1A are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) rating. Both are active production parts from KYOCERA AVX.

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements. For applications operating at or below 1500V, either part is suitable. For circuits requiring higher voltage margin or tighter capacitance tolerance, the 1812GC822KAT1A is the appropriate choice.
