Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1812SC332MAT1A is determined by the following critical parameters:

• Capacitance Value: Must remain 3300 pF to maintain circuit functionality
• Package Dimensions: Must conform to 1812 (4532 Metric) form factor for PCB compatibility
• Mounting Type: Must be Surface Mount MLCC for assembly compatibility
• Temperature Coefficient: X7R specification ensures stable performance across the operating temperature range
• Voltage Rating: Substitute parts must meet or exceed the 1500V rated voltage requirement
• Compliance Standards: RoHS3 compliance and MSL rating must be maintained

The 1812HC332KAT1A qualifies as a substitute part because it maintains identical capacitance, package dimensions, mounting type, and temperature coefficient while providing enhanced electrical performance through higher voltage rating and improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC332MAT1A and 1812HC332KAT1A maintain Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. The 1812HC332KAT1A provides enhanced electrical performance through doubled voltage rating (3000V versus 1500V) and improved capacitance tolerance (±10% versus ±20%), while maintaining identical physical package dimensions and mounting characteristics. Selection between these parts depends on circuit voltage requirements and tolerance specifications. The substitute part is suitable for applications where higher voltage margin or tighter tolerance is beneficial. Both parts are available in production quantities with established supply chains.

Frequently Asked Questions (FAQ)

Q: Can the 1812HC332KAT1A replace the 1812SC332MAT1A in existing designs?

A: Yes, the 1812HC332KAT1A is electrically and mechanically compatible. Both parts share identical capacitance (3300 pF), package dimensions (1812/4532 Metric), and temperature coefficient (X7R). The substitute part provides higher voltage rating and tighter tolerance. Physical clearance must be verified as the substitute has maximum thickness of 0.110" compared to 0.087" for the main part.

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

A: The primary differences are voltage rating (1500V main part versus 3000V substitute), capacitance tolerance (±20% versus ±10%), and maximum thickness (0.087" versus 0.110"). Capacitance value, package type, and temperature characteristics remain identical.

Q: Are both parts RoHS compliant?

A: Yes, both the 1812SC332MAT1A and 1812HC332KAT1A are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Does the increased thickness of the substitute part affect PCB assembly?

A: The substitute part has 0.023" greater maximum thickness (0.110" versus 0.087"). PCB design clearance and reflow profile compatibility should be verified during design review.

Q: Are both parts available from the same manufacturer?

A: Yes, both parts are manufactured by KYOCERA AVX, ensuring consistent quality and reliability standards.
