1812GC471MATME Equivalent & Substitute Parts

Part Overview

The 1812GC471MATME is a 470 pF ceramic capacitor rated for 2000V (2kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 1812 (4532 Metric) surface mount package. This high-voltage MLCC is designed for general-purpose applications requiring stable capacitance across operating temperatures from -55°C to 125°C. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching or exceeding electrical specifications while maintaining mechanical compatibility within the 1812 package footprint.

Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC471MATME is determined by the following criteria:

• Capacitance value must equal 470 pF
• Voltage rating must be equal to or greater than 2000V
• Package must be 1812 (4532 Metric) for mechanical compatibility
• Mounting type must be Surface Mount, MLCC
• Operating temperature range must encompass -55°C to 125°C
• RoHS and MSL compliance must be maintained

Substitute parts are grouped into two categories: direct equivalents with improved tolerance specifications, and upgraded variants with higher voltage ratings that provide additional design margin.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and full ROHS3 compliance with MSL 1 rating, ensuring equivalent environmental and regulatory qualification to the 1812GC471MATME.

1812GA471JAT1A offers improved tolerance specification (±5% versus ±20%) with identical voltage and temperature coefficient characteristics, suitable for applications requiring tighter capacitance control at 2000V rating.

1812GC471KAT1A provides intermediate tolerance improvement (±10%) while maintaining X7R temperature coefficient and 2000V voltage rating, with identical physical dimensions to the main part.

1812HC471KAT1A and KGM43ER73U471KV both provide 3000V voltage rating with ±10% tolerance and X7R temperature coefficient, offering 50% additional voltage margin over the 2000V specification. Both parts maintain 1812 package compatibility and identical operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can 1812GA471JAT1A replace 1812GC471MATME in all applications?

A: Yes, provided the application does not require X7R temperature coefficient. The 1812GA471JAT1A uses C0G/NP0 temperature coefficient, which provides superior stability but different frequency and voltage characteristics. Verify temperature coefficient requirements before substitution.

Q: What is the primary advantage of 1812HC471KAT1A and KGM43ER73U471KV?

A: Both parts provide 3000V voltage rating compared to the 2000V rating of 1812GC471MATME, offering 50% additional design margin. This higher voltage rating allows operation in circuits with higher transient voltage conditions while maintaining the same 470 pF capacitance and 1812 package footprint.

Q: Are all substitute parts available in the same packaging format?

A: No. 1812GA471JAT1A is available in Cut Tape (CT) and Digi-Reel packaging, while 1812GC471KAT1A, 1812HC471KAT1A, and KGM43ER73U471KV are supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly process.

Q: Can substitute parts be used interchangeably on the same PCB assembly?

A: Yes, all substitute parts use identical 1812 (4532 Metric) package dimensions and surface mount footprint. Physical board layout compatibility is maintained across all listed parts.

Q: What tolerance specification should I select?

A: Select based on circuit requirements. The ±20% tolerance of 1812GC471MATME is suitable for general-purpose filtering. The ±10% tolerance of 1812GC471KAT1A, 1812HC471KAT1A, and KGM43ER73U471KV provides improved accuracy. The ±5% tolerance of 1812GA471JAT1A is required for precision applications with tight capacitance specifications.
