Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC272MAT9A is determined by strict equivalence in the following critical parameters:

• Capacitance Value: Must be 2700 pF (no deviation permitted)
• Voltage Rating: Must be 2000V (2kV) or higher
• Temperature Coefficient: Must be X7R (ensures stable capacitance across temperature range)
• Package Format: Must be 1812 (4532 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.181" L x 0.126" W and 0.071" thickness for PCB layout compatibility
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part 1812GC272KAT1A meets all these criteria while offering improved tolerance specification (±10% versus ±20%), representing an upgrade path for applications requiring tighter capacitance control.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812GC272MAT9A and 1812GC272KAT1A are Active products from KYOCERA AVX with identical ROHS3 compliance and MSL 1 ratings, ensuring regulatory and environmental compatibility. The primary distinction is tolerance specification: the 1812GC272MAT9A provides ±20% tolerance, while the 1812GC272KAT1A offers ±10% tolerance. Selection between these parts should be based on circuit requirements for capacitance accuracy. Applications requiring tighter capacitance control within ±10% should specify 1812GC272KAT1A. Applications where ±20% tolerance is acceptable may use either part. Both parts are electrically and mechanically interchangeable within their respective tolerance bands, with identical voltage ratings, temperature coefficients, and physical dimensions ensuring direct PCB substitution.

Frequently Asked Questions (FAQ)

Q: Can 1812GC272KAT1A replace 1812GC272MAT9A in existing designs?

A: Yes. Both parts share identical capacitance (2700 pF), voltage rating (2000V), temperature coefficient (X7R), package format (1812), and physical dimensions. The 1812GC272KAT1A provides superior tolerance (±10% versus ±20%), making it a direct upgrade. No PCB layout modifications are required.

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

A: Tolerance defines the acceptable deviation from the nominal 2700 pF capacitance value. The 1812GC272MAT9A allows ±20% deviation (2160 pF to 3240 pF), while 1812GC272KAT1A allows ±10% deviation (2430 pF to 2970 pF). Applications with strict capacitance requirements should specify the ±10% tolerance part.

Q: Are there packaging differences between these substitute parts?

A: The 1812GC272MAT9A is supplied in standard packaging, while 1812GC272KAT1A is supplied in Tape & Reel (TR) format. Both maintain identical component specifications and are suitable for automated assembly processes. Tape & Reel packaging is standard for high-volume production environments.

Q: Do both parts meet the same compliance standards?

A: Yes. Both 1812GC272MAT9A and 1812GC272KAT1A are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8532.24.0020.

Q: Can these parts be used interchangeably in high-voltage applications?

A: Yes. Both parts are rated for 2000V (2kV) with X7R temperature coefficient, ensuring stable performance across -55°C to 125°C operating range. Electrical and thermal characteristics are equivalent, supporting direct substitution in high-voltage general-purpose applications.
