Substitute Part Grouping Explanation

Substitution for the 1812SC272KAT1A is determined by the following criteria:

• Capacitance Value: Must be 2700 pF
• Tolerance: Must be ±10%
• Temperature Coefficient: Must be X7R
• Package / Case: Must be 1812 (4532 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must be -55°C to 125°C
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part 1812GC272KAT1A meets all these criteria with an enhanced voltage rating of 2000V (2kV), providing superior performance margin while maintaining full mechanical and electrical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC272KAT1A and 1812GC272KAT1A are active production parts with full ROHS3 compliance and identical MSL 1 ratings. The 1812GC272KAT1A offers a 500V higher voltage rating (2000V vs 1500V) while maintaining all other electrical and mechanical specifications. Selection between these parts depends on circuit voltage requirements: use 1812SC272KAT1A where 1500V rating is specified, or 1812GC272KAT1A where higher voltage margin is required or preferred. The substitute part offers significantly higher inventory availability (11799 units vs 1069 units).

Frequently Asked Questions (FAQ)

Q: Can 1812GC272KAT1A replace 1812SC272KAT1A in all applications?

A: Yes, provided the circuit design permits the higher 2000V voltage rating. The substitute part is mechanically and electrically compatible with identical capacitance, tolerance, temperature coefficient, package dimensions, and operating temperature range.

Q: Are there any physical differences between these parts?

A: No. Both parts use the identical 1812 (4532 metric) package with dimensions of 4.60mm length, 3.20mm width, and 1.80mm maximum thickness. They are pin-compatible and footprint-compatible.

Q: What is the key difference between these two parts?

A: The primary difference is the voltage rating. The 1812SC272KAT1A is rated at 1500V (1.5kV), while the 1812GC272KAT1A is rated at 2000V (2kV). All other specifications including capacitance value, tolerance, temperature coefficient, and package are identical.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) rating.

Q: Which part should I select for new designs?

A: Selection is based on circuit voltage requirements. If the application requires 1500V rating, use 1812SC272KAT1A. If higher voltage margin is beneficial or the application permits 2000V rating, 1812GC272KAT1A is suitable and offers superior availability.
