1808HA330MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1808HA330MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 33 pF, rated for 3000V (3kV) operation. This surface-mount multilayer ceramic capacitor (MLCC) features C0G/NP0 temperature coefficient characteristics and is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating temperature range. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), making it suitable for direct integration into high-voltage circuit designs without environmental conditioning requirements.

Substitute parts are identified based on matching or exceeding the core electrical and mechanical specifications while maintaining compatibility with the 1808 (4520 Metric) package footprint and surface-mount assembly process.

Parameter Comparison

Engineering Selection Recommendations

1808JA330KAT1A (KYOCERA AVX): This substitute offers improved tolerance specification (±10% versus ±20%) and elevated voltage rating (4000V versus 3000V). Both parameters represent enhancements over the main part. The part maintains identical temperature coefficient, operating range, and package footprint. Active production status and ROHS3 compliance confirm ongoing availability and regulatory alignment.

C4520C0G3F330K160KA (TDK Corporation): This substitute maintains the original 3000V voltage rating and improves tolerance to ±10%. Physical dimensions differ slightly within the 1808 package envelope (4.50mm length versus 4.60mm, 1.80mm thickness versus 1.45mm). Active production status and ROHS3 compliance are confirmed. Cross-manufacturer substitution is supported by matching electrical specifications and package compatibility.

Both substitute parts are qualified for direct replacement in applications where the original 1808HA330MAT1A is specified, with the understanding that enhanced voltage or tolerance ratings do not create functional incompatibility.

Frequently Asked Questions (FAQ)

Q: Can 1808JA330KAT1A replace 1808HA330MAT1A in all applications?

A: Yes. The 1808JA330KAT1A meets all mandatory substitution criteria with improved voltage rating (4000V) and tolerance (±10%). The higher voltage rating does not create incompatibility; it represents a performance upgrade. Identical package footprint and temperature coefficient ensure mechanical and electrical compatibility.

Q: What is the difference between ±20% and ±10% tolerance?

A: Tolerance defines the allowable deviation from the nominal 33 pF capacitance value. The 1808HA330MAT1A allows deviation between 26.4 pF and 39.6 pF. The substitute parts with ±10% tolerance allow deviation between 29.7 pF and 36.3 pF, providing tighter capacitance control. Tighter tolerance does not create incompatibility; it improves circuit predictability.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist within the 1808 package specification. The 1808HA330MAT1A has maximum thickness of 1.45mm, while 1808JA330KAT1A reaches 2.20mm and C4520C0G3F330K160KA reaches 1.80mm. All dimensions remain within the 1808 (4520 Metric) package envelope and are compatible with standard surface-mount assembly processes.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts listed carry MSL 1 (Unlimited), indicating no moisture conditioning is required prior to assembly. This eliminates environmental control requirements during storage and handling.

Q: Can I use C4520C0G3F330K160KA from a different manufacturer?

A: Yes. Cross-manufacturer substitution is supported when electrical specifications, temperature coefficient, voltage rating, and package footprint match the original part. TDK Corporation's C4520C0G3F330K160KA meets all these criteria and maintains ROHS3 compliance.
