1812HA331KATME Equivalent & Substitute Parts

Part Overview

The 1812HA331KATME is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 330 pF, rated for 3000V (3kV), and featuring C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 Metric) package is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating temperature range. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). 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 1812HA331KATME is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 pF
• Tolerance: ±10%
• Voltage rating: 3000V (3kV)
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C to 125°C
• Package designation: 1812 (4532 Metric)
• Mounting type: Surface Mount, MLCC
• Compliance certifications: ROHS3, REACH Unaffected

Parts meeting all these criteria are classified as direct parametric equivalents. Dimensional variations within the 1812 package specification do not preclude substitution provided all electrical and compliance parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed—1812HA331KATME, 1812HA331KAT1A, and C4532C0G3F331K250KA—are active production components with identical electrical specifications and full compliance certifications (ROHS3, REACH Unaffected). Selection between these parts may be based on:

• Packaging format: 1812HA331KAT1A and C4532C0G3F331K250KA are supplied in Tape & Reel format, suitable for automated assembly; 1812HA331KATME is supplied in bulk packaging.
• Manufacturer preference: KYOCERA AVX parts (1812HA331KATME and 1812HA331KAT1A) versus TDK Corporation (C4532C0G3F331K250KA).
• Dimensional tolerance: TDK part C4532C0G3F331K250KA exhibits slightly larger maximum thickness (2.80mm vs. 2.20mm) and marginally smaller length (4.50mm vs. 4.60mm), which may impact PCB layout in space-constrained applications.
• Inventory availability: Current stock levels vary across suppliers and part numbers.

Frequently Asked Questions (FAQ)

Q: Can 1812HA331KAT1A be used as a direct replacement for 1812HA331KATME?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical specifications (330 pF, ±10%, 3000V, C0G/NP0, -55°C to 125°C). The primary difference is packaging format: 1812HA331KAT1A is supplied in Tape & Reel, while 1812HA331KATME is supplied in bulk. Electrical performance and compliance are equivalent.

Q: Is the TDK C4532C0G3F331K250KA compatible with designs using 1812HA331KATME?

A: Electrical compatibility is confirmed. All three parts meet identical capacitance, voltage, temperature coefficient, and compliance requirements. However, the TDK part exhibits dimensional differences: maximum thickness of 2.80mm (versus 2.20mm for KYOCERA AVX parts) and length of 4.50mm (versus 4.60mm). Verify PCB layout clearances and component placement constraints before substitution.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires equivalence across capacitance (330 pF), tolerance (±10%), voltage rating (3000V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), package type (1812/4532 Metric), and compliance certifications (ROHS3, REACH Unaffected). Packaging format and minor dimensional variations do not affect electrical substitution.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications. Moisture sensitivity level is 1 (unlimited) for all parts.

Q: What is the significance of the 1812 package designation?

A: The 1812 designation refers to the metric 4532 package size (4.60mm x 3.20mm nominal for KYOCERA AVX; 4.50mm x 3.20mm for TDK). This is a standard surface-mount MLCC package. All listed parts conform to this package specification, ensuring PCB footprint compatibility within dimensional tolerances.
