Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812CC333MATME is determined by the following critical parameters:

• Capacitance Value: Must be 0.033 µF (exact match required)
• Temperature Coefficient: Must be X7R (ensures stable capacitance across operating temperature range)
• Package / Case: Must be 1812 (4532 Metric) (ensures mechanical and electrical compatibility with PCB layout)
• Mounting Type: Must be Surface Mount, MLCC (maintains assembly process compatibility)
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Voltage Rating: Must be equal to or greater than 630V (higher voltage ratings provide additional design margin)
• Compliance: Must maintain ROHS3 and REACH compliance status

Two substitute parts meet these criteria with variations in tolerance and voltage rating specifications.

Parameter Comparison

Engineering Selection Recommendations

1812CC333KAT1A (KYOCERA AVX): This substitute offers tighter tolerance (±10% versus ±20%) while maintaining identical voltage rating (630V) and physical dimensions. Both parts are manufactured by KYOCERA AVX, ensuring consistent material composition and performance characteristics. Selection of this part is appropriate when improved capacitance accuracy is required without increasing voltage margin.

GRM43DR73A333KW01L (Murata Electronics): This substitute provides elevated voltage rating (1000V versus 630V) in the same 1812 package footprint. Physical dimensions vary slightly (length 4.50mm versus 4.60mm, thickness 2.20mm versus 1.80mm). This part is suitable for applications requiring higher voltage margin or when Murata component qualification is specified. The increased thickness must be verified against PCB assembly clearance requirements.

All three parts maintain active production status, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1), ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can 1812CC333KAT1A directly replace 1812CC333MATME in existing designs?

A: Yes. Both parts share identical capacitance (0.033 µF), voltage rating (630V), temperature coefficient (X7R), package (1812), and physical dimensions. The primary difference is tolerance specification (±10% versus ±20%), which represents an improvement in capacitance accuracy. No PCB layout or assembly process modifications are required.

Q: What are the physical compatibility considerations for GRM43DR73A333KW01L?

A: GRM43DR73A333KW01L maintains the same 1812 package designation and footprint length (4.50mm versus 4.60mm is within standard tolerance). However, thickness increases from 1.80mm to 2.20mm maximum. Verify clearance above the component on the PCB assembly to prevent interference with adjacent components or conformal coating processes.

Q: Why would GRM43DR73A333KW01L be selected over the other options?

A: Selection of GRM43DR73A333KW01L is appropriate when circuit design requires 1000V voltage rating for additional safety margin, when Murata component qualification is mandated by design standards, or when supply chain diversification across manufacturers is required. The higher voltage rating provides enhanced reliability in high-voltage applications.

Q: Are all three parts suitable for the same operating temperature range?

A: Yes. All three parts support -55°C ~ 125°C operating temperature range with X7R temperature coefficient, ensuring stable capacitance performance across the full specified temperature band.

Q: What is the significance of tolerance differences between these parts?

A: The main part (1812CC333MATME) specifies ±20% tolerance, while both substitutes offer ±10% tolerance. Tighter tolerance improves circuit performance in applications sensitive to capacitance variation. Selection depends on circuit requirements; applications with relaxed tolerance specifications can use any of the three parts interchangeably.

Q: Are all parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
