1812GC272MAT1C Equivalent & Substitute Parts

Part Overview

The 1812GC272MAT1C is a 2700 pF ceramic capacitor rated for 2000V (2kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) 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 active in production with robust inventory availability. Substitute parts are identified when equivalent electrical performance can be maintained while accommodating specific design requirements such as tolerance specifications or packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1812GC272MAT1C is determined by strict equivalence in the following critical parameters:

• Capacitance Value: Must remain 2700 pF
• Voltage Rating: Must maintain 2000V (2kV) minimum
• Temperature Coefficient: Must be X7R for thermal stability
• Package / Case: Must be 1812 (4532 Metric) for mechanical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.181" L x 0.126" W and 0.071" thickness

The substitute part 1812GC272KAT1A meets all these criteria. The primary difference is the tolerance specification, which is tightened from ±20% to ±10%, representing an upgrade in capacitance accuracy without affecting electrical performance or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812GC272MAT1C and 1812GC272KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on tolerance requirements:

• 1812GC272MAT1C is suitable for applications where ±20% capacitance tolerance is acceptable, offering standard cost positioning.
• 1812GC272KAT1A provides tightened ±10% tolerance for applications requiring higher capacitance accuracy, with significantly higher inventory availability (11,799 pcs vs. 1,141 pcs).

Both parts are electrically and mechanically interchangeable in 1812 package footprints and maintain identical thermal performance across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can 1812GC272KAT1A replace 1812GC272MAT1C in existing designs?

A: Yes. The substitute part maintains identical capacitance value, voltage rating, temperature coefficient, and physical dimensions. The tightened tolerance (±10% vs. ±20%) represents improved accuracy and is functionally compatible with all applications designed for the original part.

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

A: The tolerance specification differs. 1812GC272MAT1C has ±20% tolerance, while 1812GC272KAT1A has ±10% tolerance. All other electrical and mechanical parameters are equivalent.

Q: Are there packaging differences between these parts?

A: The main part is specified with standard packaging, while the substitute part is supplied in Tape & Reel (TR) format. Both use identical 1812 (4532 Metric) package cases with matching physical dimensions and mounting characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited), ensuring equivalent environmental and regulatory compliance.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance requirements. For applications requiring ±10% capacitance accuracy, 1812GC272KAT1A is the appropriate choice. For applications where ±20% tolerance is acceptable, either part is suitable based on availability and cost considerations.
