1808SA330KATME Equivalent & Substitute Parts

Part Overview

The 1808SA330KATME is a 33 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V (1.5kV) operation with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) in 1808 (4520 Metric) package is designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part maintains Active product status 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, or meet specific voltage margin requirements in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808SA330KATME is determined by the following critical parameters:

• Capacitance Value: Must be 33 pF ±10%
• Temperature Coefficient: Must be C0G or NP0 (equivalent specifications)
• Package / Case: Must be 1808 (4520 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Voltage Rating: Must be equal to or greater than 1500V (1.5kV) for direct substitution without circuit redesign

The identified substitute parts meet all mandatory parameters. Voltage ratings above 1500V represent upgrades that provide additional safety margin and are electrically compatible in applications designed for the original 1500V specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory compliance for current and future applications.

1808SA330KATME (Main Part): Select for applications where the 1500V rating is specified and component thickness of 0.057" (1.45mm) is a design constraint. This part offers the thinnest profile among the three options.

1808JA330KAT1A (KYOCERA AVX Upgrade): Select when higher voltage margin is required or when supply chain preference favors KYOCERA AVX as the sole manufacturer. The 4000V rating provides the highest safety margin. Note the increased thickness of 0.087" (2.20mm) must be accommodated in PCB layout.

C4520C0G3F330K160KA (TDK Corporation): Select when multi-source component strategy requires TDK Corporation as an approved alternative manufacturer, or when the 3000V rating provides adequate margin with moderate thickness of 0.071" (1.80mm). Dimensional variation (0.177" L vs. 0.181" L) requires PCB footprint verification.

Frequently Asked Questions (FAQ)

Q: Can 1808JA330KAT1A or C4520C0G3F330K160KA be used as direct replacements for 1808SA330KATME?

A: Yes. Both substitute parts are electrically and mechanically compatible. They share identical capacitance (33 pF), tolerance (±10%), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and package designation (1808 / 4520 Metric). Higher voltage ratings are backward compatible with 1500V circuit designs.

Q: What are the physical dimension differences between substitute parts?

A: The main part and 1808JA330KAT1A share identical length and width (0.181" L x 0.079" W / 4.60mm x 2.00mm). C4520C0G3F330K160KA has slightly reduced length (0.177" L / 4.50mm). Thickness varies: main part 0.057" (1.45mm), 1808JA330KAT1A 0.087" (2.20mm), and C4520C0G3F330K160KA 0.071" (1.80mm). PCB layout must accommodate these thickness variations.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts are RoHS3 compliant with REACH unaffected status, suitable for applications requiring environmental and regulatory compliance.

Q: What is the moisture sensitivity rating for these parts?

A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly.

Q: Which substitute part should be selected for maximum voltage safety margin?

A: The 1808JA330KAT1A provides the highest voltage rating at 4000V (4kV), offering the greatest margin above the original 1500V specification. This selection is appropriate when design requirements prioritize voltage headroom.
