1812AC223MAT3A\SB Equivalent & Substitute Parts

Part Overview

The 1812AC223MAT3A\SB is a 0.022 µF ceramic capacitor rated for 1000V (1kV) 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 ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812AC223MAT3A\SB is determined by the following critical parameters:

• Capacitance Value: Must be 0.022 µF
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R
• Package / Case: Must be 1812 (4532 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C to 125°C
• RoHS Compliance: Must maintain ROHS3 compliance
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

Tolerance variations (±20% vs. ±10%) and thickness differences within acceptable mechanical limits do not preclude substitution when all critical parameters are met. Packaging format (Tape & Reel vs. bulk) represents a procurement variation rather than a functional constraint.

Parameter Comparison

Engineering Selection Recommendations

1812AC223KAT1A (KYOCERA AVX): This upgrade substitute offers tighter tolerance (±10% vs. ±20%), providing improved capacitance accuracy while maintaining identical voltage rating, temperature coefficient, and package specifications. Both parts are manufactured by KYOCERA AVX and carry ROHS3 compliance. The upgrade substitute is suitable for applications requiring enhanced capacitance stability.

CHV1812N1K0223MXT (Cal-Chip Electronics, Inc.): This direct substitute maintains the same capacitance tolerance (±20%) and all critical electrical parameters as the main part. The thickness specification differs by 0.008" (0.20mm), which remains within typical PCB assembly tolerances for 1812 package components. Both parts are ROHS3 compliant and carry MSL 1 rating. This substitute is suitable for applications where manufacturer flexibility is acceptable.

All three parts maintain active production status and full regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can 1812AC223KAT1A replace 1812AC223MAT3A\SB in existing designs?

A: Yes. Both parts share identical capacitance (0.022 µF), voltage rating (1000V), temperature coefficient (X7R), package (1812), and operating temperature range (-55°C to 125°C). The upgrade substitute features tighter tolerance (±10%), which improves performance in applications sensitive to capacitance variation.

Q: What is the functional difference between ±20% and ±10% tolerance?

A: Tolerance defines the allowable deviation from the nominal capacitance value. A ±20% tolerance permits capacitance between 0.0176 µF and 0.0264 µF, while ±10% permits 0.0198 µF to 0.0242 µF. Applications requiring tighter capacitance control benefit from the ±10% specification.

Q: Does the 0.008" thickness difference between CHV1812N1K0223MXT and the main part affect PCB assembly?

A: No. The thickness difference (0.118" vs. 0.110") falls within standard PCB assembly tolerances for 1812 package components and does not affect reflow soldering, component placement, or electrical performance.

Q: Are all three parts suitable for high-voltage applications?

A: Yes. All parts are rated for 1000V (1kV) with X7R temperature coefficient, supporting stable operation across -55°C to 125°C. All three parts carry ROHS3 compliance and MSL 1 (unlimited moisture sensitivity).

Q: Can I mix manufacturers in the same design?

A: Yes. Both KYOCERA AVX and Cal-Chip Electronics parts meet identical electrical specifications, package requirements, and regulatory compliance. Mixing manufacturers is permissible when procurement or inventory constraints require flexibility.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This simplifies inventory management and reduces handling constraints compared to higher MSL ratings.
