1812GC221MATME Equivalent & Substitute Parts

Part Overview

The 1812GC221MATME is a 220 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 638 units in stock. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC221MATME is determined by the following critical parameters:

• Capacitance value: 220 pF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Voltage rating: Minimum 2000V (2kV) or higher
• Temperature coefficient: X7R or equivalent stability class
• Operating temperature range: -55°C to 125°C (minimum requirement)
• Mounting type: Surface Mount, MLCC
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

Two substitute parts meet these criteria with allowable variations in tolerance and temperature coefficient characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

C1812C221MGRAC7800 (KEMET): This substitute maintains identical electrical specifications (220 pF, ±20%, 2000V, X7R) with the same operating temperature range. The part features low ESL characteristics and is available in higher inventory (2569 units). Physical dimensions are slightly reduced (4.50mm length, 1.55mm thickness), which may provide layout advantages in space-constrained applications.

C4532C0G3F221K200KA (TDK Corporation): This substitute offers enhanced voltage rating (3000V versus 2000V) and improved tolerance (±10% versus ±20%), providing additional design margin. The temperature coefficient is C0G/NP0, which provides superior temperature stability compared to X7R. Thickness is increased to 2.20mm. This part is available in the largest inventory (39968 units) and is suitable for applications requiring higher voltage headroom or tighter capacitance tolerance.

Frequently Asked Questions (FAQ)

Q: Can C1812C221MGRAC7800 be used as a direct replacement for 1812GC221MATME?

A: Yes. Both parts share identical capacitance (220 pF), tolerance (±20%), voltage rating (2000V), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). Physical dimensions are within acceptable variation for 1812 package specifications.

Q: What is the key difference between C4532C0G3F221K200KA and the original part?

A: The TDK part provides higher voltage rating (3000V versus 2000V) and tighter tolerance (±10% versus ±20%). The temperature coefficient is C0G/NP0 instead of X7R, offering superior temperature stability. These differences make it suitable for applications requiring enhanced performance margins.

Q: Are all three parts compatible with the same PCB layout?

A: The 1812 (4532 Metric) package designation is identical for all three parts. However, physical dimensions vary slightly: length ranges from 4.50mm to 4.60mm, and thickness ranges from 1.55mm to 2.20mm. PCB footprints designed for the 1812 package will accommodate all three parts, though height clearance should be verified for the TDK part (2.20mm thickness).

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change over the -55°C to 125°C temperature range. C0G/NP0 provides superior stability with minimal capacitance change across temperature. C0G/NP0 is preferred for applications requiring tight capacitance tolerance across temperature variations.

Q: Which substitute part should be selected for maximum inventory availability?

A: C4532C0G3F221K200KA (TDK Corporation) has the highest inventory level at 39968 units, followed by C1812C221MGRAC7800 (KEMET) at 2569 units.
