1812AC562MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812AC562MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 5600 pF and rated voltage of 1000V (1kV). This surface-mount multilayer ceramic capacitor (MLCC) features X7R temperature coefficient characteristics and is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when design requirements allow for higher voltage ratings, improved tolerance specifications, or enhanced inventory availability while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1812AC562MAT1A is permissible when the following conditions are met:

Mandatory Compatibility Parameters:

• Capacitance value must remain 5600 pF
• Package / Case must be 1812 (4532 Metric)
• Mounting type must be Surface Mount, MLCC
• Temperature coefficient must be X7R
• Operating temperature range must be -55°C to 125°C or wider
• RoHS3 compliance must be maintained

Allowable Variation Parameters:

• Voltage rating may be equal to or higher than 1000V (1kV)
• Tolerance may be equal to or tighter than ±20%
• Thickness may vary within mechanical constraints of the 1812 package

The identified substitute part 1812SC562KAT1A meets all mandatory compatibility requirements while offering improved electrical specifications (higher voltage rating and tighter tolerance) within the same physical package footprint.

Parameter Comparison

Engineering Selection Recommendations

The 1812SC562KAT1A substitute part is electrically and mechanically compatible with the 1812AC562MAT1A for applications where the design voltage margin permits. Both parts are manufactured by KYOCERA AVX and maintain Active product status with full RoHS3 compliance and REACH unaffected status. The substitute offers superior electrical performance through a 50% increase in voltage rating (1500V versus 1000V) and improved capacitance tolerance (±10% versus ±20%), making it suitable for designs requiring enhanced reliability margins or tighter capacitance specifications. The increased thickness of the substitute part (2.80mm versus 1.80mm) must be verified against PCB assembly constraints and available board space. Both parts share identical length and width dimensions, ensuring footprint compatibility on standard 1812 land patterns.

Frequently Asked Questions (FAQ)

Q: Can the 1812SC562KAT1A be used as a direct replacement for the 1812AC562MAT1A?

A: Yes, the 1812SC562KAT1A is mechanically and electrically compatible for direct substitution on 1812 land patterns. The substitute maintains identical capacitance value, temperature coefficient, and operating temperature range. Verify that the increased thickness (2.80mm versus 1.80mm) does not conflict with PCB assembly clearances or component stacking requirements.

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

A: The primary differences are voltage rating (1500V substitute versus 1000V main part), capacitance tolerance (±10% substitute versus ±20% main part), and physical thickness (2.80mm substitute versus 1.80mm main part). All other electrical and mechanical specifications remain identical.

Q: Are both parts RoHS3 compliant?

A: Yes, both the 1812AC562MAT1A and 1812SC562KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts have Moisture Sensitivity Level 1 (MSL 1), indicating unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Can I use the main part in an application designed for the substitute?

A: The 1812AC562MAT1A can be used in applications originally specified for the 1812SC562KAT1A only if the circuit design voltage margin accommodates the lower 1000V rating. The wider tolerance of the main part (±20%) may affect circuit performance in applications requiring the tighter ±10% tolerance of the substitute.
