Substitute Part Grouping Explanation

Substitution for the 1812SC272KAT1A is determined by strict equivalence in the following critical parameters:

• Capacitance Value: 2700 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical Dimensions: 0.181" L × 0.126" W, 0.071" thickness (exact match required)

The substitute part 1812GC272KAT1A maintains all critical parameters identical to the main part with one exception: the voltage rating is increased from 1500V to 2000V. This represents an upgrade substitution, as the higher voltage rating provides enhanced performance margin while maintaining full compatibility with all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC272KAT1A and 1812GC272KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 1812GC272KAT1A represents an upgrade option with identical electrical and mechanical characteristics except for increased voltage rating (2000V versus 1500V). Selection between these parts depends on circuit voltage requirements: use 1812SC272KAT1A where the 1500V rating meets design specifications, or select 1812GC272KAT1A where higher voltage margin is required or preferred. Both parts maintain identical footprint, thermal performance, and compliance certifications, ensuring direct substitution capability at the board level.

Frequently Asked Questions (FAQ)

Q: Can 1812GC272KAT1A replace 1812SC272KAT1A in existing designs?

A: Yes. The 1812GC272KAT1A is a direct mechanical and electrical substitute with identical capacitance, tolerance, temperature coefficient, package dimensions, and mounting characteristics. The higher voltage rating (2000V versus 1500V) provides additional performance margin without affecting circuit operation.

Q: Are the physical footprints identical?

A: Yes. Both parts use the 1812 (4532 Metric) package with identical dimensions: 0.181" L × 0.126" W (4.60mm × 3.20mm) and 0.071" (1.80mm) thickness. No PCB layout modifications are required for substitution.

Q: Do both parts have the same temperature stability?

A: Yes. Both parts feature X7R temperature coefficient and operate across the identical temperature range of -55°C to 125°C, ensuring equivalent thermal performance in the application.

Q: What is the difference between these two parts?

A: The primary difference is the voltage rating: 1812SC272KAT1A is rated for 1500V, while 1812GC272KAT1A is rated for 2000V. All other specifications—capacitance, tolerance, package, dimensions, and compliance certifications—are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both 1812SC272KAT1A and 1812GC272KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
