1808SA330MAT1A Equivalent & Substitute Parts

Part Overview

The 1808SA330MAT1A 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). Substitute parts are identified when equivalent capacitance and temperature coefficient specifications are maintained while allowing for voltage rating upgrades or tolerance improvements within the same package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1808SA330MAT1A is determined by the following critical parameters:

• Capacitance Value: Must remain 33 pF (exact match required)
• Temperature Coefficient: Must be C0G or NP0 (interchangeable designations for the same characteristic)
• Package / Case: Must be 1808 (4520 Metric) to ensure mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C to 125°C minimum

Substitute parts may differ in:

• Voltage Rating: Higher voltage ratings are acceptable as they provide enhanced safety margin and component reliability
• Tolerance: Tighter tolerances (±10%) represent performance upgrades
• Manufacturer: Different manufacturers producing equivalent specifications

The identified substitute parts meet all critical parameters while offering improved voltage ratings or tolerance specifications.

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.

1808JA330KAT1A (KYOCERA AVX) provides a 4kV voltage rating upgrade with improved ±10% tolerance. The increased thickness of 0.087" (2.20mm) versus the original 0.057" (1.45mm) must be verified against PCB assembly clearance requirements. This part is suitable for applications requiring enhanced voltage margin and tighter capacitance tolerance.

C4520C0G3F330K160KA (TDK Corporation) offers a 3kV voltage rating upgrade with ±10% tolerance and intermediate thickness of 0.071" (1.80mm). The dimensional variation in length (0.177" versus 0.181") remains within typical PCB footprint tolerances for 1808 packages. This part provides a balanced upgrade path with moderate voltage enhancement.

Selection between substitute parts depends on available PCB clearance for component height and the specific voltage margin requirements of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can 1808JA330KAT1A or C4520C0G3F330K160KA be used as direct replacements for 1808SA330MAT1A?

A: Yes, both parts are electrically and mechanically compatible substitutes. All three maintain identical capacitance (33 pF), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and 1808 (4520 Metric) package classification. The substitute parts provide higher voltage ratings and improved tolerance specifications.

Q: What is the significance of the voltage rating difference between the three parts?

A: The 1808SA330MAT1A is rated for 1500V operation. The substitute parts offer 3000V (C4520C0G3F330K160KA) and 4000V (1808JA330KAT1A) ratings. Higher voltage ratings provide increased safety margin and component reliability in high-voltage circuit applications. Selection depends on the actual circuit voltage requirements.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Minor dimensional variations exist. The 1808JA330KAT1A has maximum thickness of 0.087" (2.20mm) compared to 0.057" (1.45mm) for the original part. The C4520C0G3F330K160KA has length of 0.177" versus 0.181" for the original. These variations must be evaluated against specific PCB assembly clearance and layout constraints.

Q: Do all three parts meet the same compliance and regulatory requirements?

A: Yes. All parts are RoHS3 compliant, REACH unaffected, classified as EAR99, and maintain MSL 1 (Unlimited) moisture sensitivity rating. Regulatory compliance is equivalent across all three options.

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

A: Tolerance defines the acceptable capacitance variation from the nominal 33 pF value. The ±20% tolerance of 1808SA330MAT1A allows variation between 26.4 pF and 39.6 pF. The ±10% tolerance of the substitute parts restricts variation to 29.7 pF to 36.3 pF, providing tighter capacitance control for applications requiring more precise component characteristics.
