1812GC151MATME Equivalent & Substitute Parts

Part Overview

The 1812GC151MATME is a 150 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX with a rated voltage of 2000V (2kV) and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 Metric) package is designed for general-purpose applications requiring high-voltage performance. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support applications requiring alternative temperature coefficients or enhanced voltage ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC151MATME is determined by the following critical parameters:

• Capacitance Value: Must be 150 pF
• Package / Case: Must be 1812 (4532 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Voltage Rating: Must meet or exceed 2000V (2kV) requirement
• Compliance: Must maintain RoHS3 compliance and MSL 1 rating

Substitute parts may differ in tolerance specification and temperature coefficient while maintaining full functional equivalence. Enhanced voltage ratings (3kV) provide superior performance margin in high-voltage applications. Temperature coefficient variations (C0G/NP0 versus X7R) affect capacitance stability across temperature ranges but do not prevent substitution in general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

1812GA151KAT1A (KYOCERA AVX Upgrade): This substitute offers tighter capacitance tolerance (±10% versus ±20%) while maintaining identical voltage rating and package specifications. Both parts are manufactured by KYOCERA AVX and share equivalent compliance certifications. The primary distinction is the temperature coefficient change from X7R to C0G/NP0, which provides superior capacitance stability across the operating temperature range. This part is suitable for applications where improved tolerance and temperature stability are beneficial without requiring voltage margin enhancement.

C4532C0G3F151K160KA (TDK Corporation MFR Recommended): This substitute provides a 50% voltage rating increase (3000V versus 2000V) while maintaining the same capacitance value and package form factor. The C0G/NP0 temperature coefficient ensures stable performance across temperature extremes. Manufactured by TDK Corporation, this part carries full RoHS3 compliance and MSL 1 rating. The enhanced voltage rating provides additional design margin for high-voltage applications and may improve long-term reliability in demanding environments. Physical dimensions differ slightly (length 4.50mm versus 4.60mm; thickness 1.80mm versus 1.80mm for main part), remaining within 1812 package specifications.

All substitute parts maintain active production status and full compliance with RoHS3 and REACH requirements, ensuring supply chain continuity and regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can 1812GA151KAT1A directly replace 1812GC151MATME in my circuit?

A: Yes. Both parts share identical capacitance (150 pF), voltage rating (2000V), package (1812), and operating temperature range (-55°C ~ 125°C). The tolerance improvement (±10% versus ±20%) and temperature coefficient change (C0G/NP0 versus X7R) represent enhancements rather than limitations. Verify that your circuit design does not specifically require X7R characteristics before substitution.

Q: What is the advantage of C4532C0G3F151K160KA over the main part?

A: The TDK part provides 50% higher voltage rating (3000V versus 2000V) in an equivalent 1812 package. This enhanced voltage margin improves reliability in high-voltage applications and provides design flexibility for future circuit modifications. The C0G/NP0 temperature coefficient ensures superior capacitance stability across the full operating temperature range compared to X7R.

Q: Are there physical compatibility concerns when substituting these parts?

A: All three parts use the 1812 (4532 Metric) surface-mount package with compatible footprints. Thickness variations are minimal (1.80mm to 2.20mm maximum), and length differences (4.50mm to 4.60mm) fall within standard 1812 package tolerances. PCB layout and reflow profiles require no modification for any of these substitutes.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All parts listed are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) rating. ECCN classification (EAR99) and HTSUS code (8532.24.0020) are identical across all parts, ensuring regulatory and export compliance equivalence.

Q: Which substitute should I select for maximum design margin?

A: C4532C0G3F151K160KA (TDK) provides the highest voltage margin at 3000V rating. If voltage margin is not critical, 1812GA151KAT1A (KYOCERA AVX) offers improved tolerance and temperature stability while maintaining the original 2000V rating and manufacturer continuity.

Q: Can I mix these parts in the same production batch?

A: Yes, provided your circuit design accepts the parameter variations listed in the comparison table. Ensure your procurement and assembly documentation clearly specifies which part number is acceptable for each position to maintain traceability and quality control.
