1812AC223MAT3A Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 1812AC223MAT3A is a 0.022 µF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 1000V (1kV) operation with X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 Metric) package is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating temperature range. 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 supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the 1812AC223MAT3A is determined by strict equivalence in the following critical parameters: capacitance value (0.022 µF), voltage rating (1000V minimum), temperature coefficient (X7R), package form factor (1812/4532 Metric), and mounting technology (surface-mount MLCC). All identified substitutes maintain these core electrical and mechanical specifications. Tolerance variations (±20% vs. ±10%) and minor dimensional differences in thickness do not preclude functional interchangeability within the same application circuit, provided the circuit design accommodates the specified tolerance range. Compliance certifications (ROHS3, REACH Unaffected, MSL 1) are maintained across all substitute options.

Parameter Comparison

Engineering Selection Recommendations

All three parts—1812AC223MAT3A, 1812AC223KAT1A, and CHV1812N1K0223MXT—are functionally equivalent for applications requiring a 0.022 µF, 1kV X7R ceramic capacitor in 1812 package form. Selection between these options should be based on procurement availability, lead time, and cost considerations.

The 1812AC223KAT1A offers tighter capacitance tolerance (±10% vs. ±20%), which may be advantageous in precision analog circuits where capacitance accuracy directly impacts circuit performance. This upgrade tolerance comes from the same manufacturer (KYOCERA AVX) and maintains identical electrical and mechanical specifications otherwise.

The CHV1812N1K0223MXT from Cal-Chip Electronics provides an alternative sourcing option with equivalent electrical performance. The maximum thickness specification of 0.118" (3.00mm) versus 0.110" (2.80mm) for the KYOCERA AVX parts represents a 0.02mm increase and should be verified against PCB assembly clearance requirements, particularly in space-constrained designs.

All parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating, ensuring compatibility with standard manufacturing processes and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can 1812AC223KAT1A replace 1812AC223MAT3A directly?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical capacitance (0.022 µF), voltage rating (1kV), temperature coefficient (X7R), and package dimensions. The 1812AC223KAT1A features improved tolerance (±10% vs. ±20%), making it suitable for applications where tighter capacitance accuracy is required.

Q: Is CHV1812N1K0223MXT mechanically compatible with the original part?

A: Yes, with a minor consideration. The CHV1812N1K0223MXT has a maximum thickness of 0.118" (3.00mm) compared to 0.110" (2.80mm) for KYOCERA AVX parts. This 0.02mm difference is negligible for most applications but should be verified in designs with tight vertical clearance constraints.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. They are suitable for standard surface-mount assembly processes without additional handling requirements.

Q: What is the primary difference between the substitute parts?

A: The 1812AC223KAT1A differs in capacitance tolerance (±10% vs. ±20%), offering higher precision. The CHV1812N1K0223MXT is from a different manufacturer (Cal-Chip Electronics) but maintains equivalent electrical specifications and differs only in maximum thickness by 0.02mm.

Q: Can these parts be used interchangeably in high-voltage applications?

A: Yes. All parts are rated for 1000V operation with X7R temperature stability across -55°C to 125°C, meeting the requirements for general-purpose high-voltage applications.
