1812CC332MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812CC332MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 3300 pF and rated voltage of 630V. This surface-mount multilayer ceramic capacitor (MLCC) features X7R temperature coefficient characteristics and is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating range. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent capacitance and package dimensions are maintained while allowing for enhanced electrical specifications such as higher voltage ratings or improved tolerance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1812CC332MAT1A is determined by strict adherence to the following electrical and mechanical parameters:

Fixed Parameters (Must Match):

• Capacitance: 3300 pF
• Temperature Coefficient: X7R
• Package / Case: 1812 (4532 Metric)
• Physical Dimensions: 0.181" L x 0.126" W (4.60mm x 3.20mm)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 630V
• Tolerance: May be equal to or tighter than ±20%
• Thickness: May vary within component design specifications

The substitute part 1812HC332KAT1A meets all fixed parameters while providing enhanced electrical specifications through higher voltage rating (3000V vs. 630V) and improved tolerance (±10% vs. ±20%).

Parameter Comparison

Engineering Selection Recommendations

Both the 1812CC332MAT1A and 1812HC332KAT1A maintain Active product status with identical ROHS3 compliance and REACH Unaffected certifications. The 1812HC332KAT1A provides enhanced electrical performance through a 3000V rated voltage specification compared to the 630V rating of the 1812CC332MAT1A, while maintaining identical capacitance and temperature coefficient characteristics. The improved tolerance specification (±10% vs. ±20%) of the substitute part offers tighter capacitance control. Both parts are classified under ECCN EAR99 and HTSUS 8532.24.0020. Selection between these parts depends on circuit voltage requirements and tolerance specifications. The increased thickness of the 1812HC332KAT1A (2.80mm vs. 1.80mm) must be evaluated against available PCB assembly clearance.

Frequently Asked Questions (FAQ)

Q: Can the 1812HC332KAT1A be used as a direct replacement for the 1812CC332MAT1A?

A: The 1812HC332KAT1A is electrically compatible as a substitute when circuit design permits the use of a higher voltage-rated component. Both parts share identical capacitance (3300 pF), temperature coefficient (X7R), and physical footprint dimensions (0.181" L x 0.126" W). The primary consideration is the increased thickness (2.80mm vs. 1.80mm), which must be verified against PCB assembly constraints.

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

A: The 1812HC332KAT1A provides three primary enhancements: rated voltage of 3000V versus 630V, tolerance of ±10% versus ±20%, and packaging in Tape & Reel format versus the standard packaging of the 1812CC332MAT1A. Component thickness increases from 1.80mm to 2.80mm.

Q: Are both parts RoHS compliant?

A: Both the 1812CC332MAT1A and 1812HC332KAT1A are ROHS3 Compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: Does the higher voltage rating of the substitute part affect circuit performance?

A: A higher voltage-rated capacitor does not negatively affect circuit performance when used in applications rated for lower voltages. The 3000V rating of the 1812HC332KAT1A provides additional safety margin in 630V applications.

Q: What is the significance of the tolerance difference?

A: The 1812HC332KAT1A tolerance of ±10% provides tighter capacitance control compared to the ±20% tolerance of the 1812CC332MAT1A. This improved tolerance may be beneficial in applications requiring precise capacitance values.

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

A: The increased thickness of the 1812HC332KAT1A (2.80mm maximum) compared to the 1812CC332MAT1A (1.80mm maximum) requires verification of available vertical clearance on the PCB assembly. Horizontal footprint dimensions remain identical.
