Equivalent & Substitute Parts for 1812CC332MAT3A

Part Overview

The 1812CC332MAT3A 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 capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or application-specific performance needs while maintaining compatibility with existing circuit designs.

Substitute Part Grouping Explanation

The 1812HC332KAT1A qualifies as a substitute for the 1812CC332MAT3A based on the following criteria:

Matching Parameters:

• Identical capacitance value: 3300 pF
• Identical package and case: 1812 (4532 Metric)
• Identical mounting type: Surface Mount, MLCC
• Identical physical length and width: 0.181" L x 0.126" W (4.60mm x 3.20mm)
• Identical temperature coefficient: X7R
• Identical operating temperature range: -55°C to 125°C
• Identical RoHS and REACH compliance status
• Identical moisture sensitivity level: MSL 1

Allowable Differences:

• Voltage rating: 1812HC332KAT1A is rated at 3000V (3kV), which exceeds the 630V requirement of the original part. Higher voltage ratings are acceptable substitutes in applications where the original voltage specification is met or exceeded.
• Tolerance: 1812HC332KAT1A has ±10% tolerance versus ±20% for the original part. Tighter tolerance is an acceptable upgrade.
• Thickness: 1812HC332KAT1A measures 0.110" (2.80mm) versus 0.071" (1.80mm) for the original part. This dimensional difference must be verified for PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812CC332MAT3A and 1812HC332KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 1812HC332KAT1A provides enhanced performance characteristics through higher voltage rating (3000V versus 630V) and tighter capacitance tolerance (±10% versus ±20%), making it suitable for applications requiring greater design margin or stricter tolerance control.

Selection between these parts should be based on PCB layout constraints. The increased thickness of the 1812HC332KAT1A (0.110" versus 0.071") must be accommodated within the available vertical clearance on the circuit board. Both parts share identical footprint dimensions and are compatible with standard 1812 (4532 Metric) placement equipment.

Frequently Asked Questions (FAQ)

Q: Can the 1812HC332KAT1A replace the 1812CC332MAT3A in my circuit?

A: Yes, provided that PCB layout accommodates the increased thickness of 0.110" (2.80mm) versus 0.071" (1.80mm). The higher voltage rating and tighter tolerance of the substitute part are compatible with applications designed for the original 630V specification.

Q: What is the significance of the voltage rating difference?

A: The 1812HC332KAT1A is rated for 3000V (3kV) compared to the 630V rating of the 1812CC332MAT3A. Higher voltage-rated capacitors can be used in lower-voltage applications without performance degradation. This provides additional design margin and reliability in the circuit.

Q: Are there tolerance implications when substituting these parts?

A: The 1812HC332KAT1A has ±10% tolerance versus ±20% for the original part. Tighter tolerance represents an upgrade that improves circuit performance predictability. Applications designed for ±20% tolerance will function correctly with ±10% tolerance components.

Q: Do both parts have identical package dimensions?

A: Both parts use the 1812 (4532 Metric) package with identical length (0.181" / 4.60mm) and width (0.126" / 3.20mm). The thickness differs: 0.071" (1.80mm) for 1812CC332MAT3A and 0.110" (2.80mm) for 1812HC332KAT1A. Verify available vertical clearance on your PCB before substitution.

Q: Are compliance certifications identical between these parts?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) rating. Both are active production parts from the same manufacturer.
