1808AC332MAT1A Equivalent & Substitute Parts

Part Overview

The 1808AC332MAT1A is a 3300 pF ceramic capacitor rated at 1000V (1kV) 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 full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified when they maintain the same capacitance value and core electrical ratings while offering improvements in tolerance, voltage rating, or packaging configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1808AC332MAT1A is determined by three critical parameters: capacitance value (3300 pF), package form factor (1808/4520 Metric), and mounting type (surface mount MLCC). The voltage rating and tolerance are secondary parameters that define upgrade or downgrade paths.

The identified substitutes maintain the same 3300 pF capacitance and 1808 package footprint. Substitution logic follows these criteria:

• Capacitance: Must be 3300 pF (no deviation)
• Package / Case: Must be 1808 (4520 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Temperature Coefficient: Must be X7R
• Voltage Rating: Equal or higher than 1000V is acceptable
• Tolerance: ±10% represents an upgrade from ±20%; both are functionally compatible

Parameter Comparison

Engineering Selection Recommendations

1808AC332KAT1A is a direct equivalent with improved tolerance specification. It maintains the same 1000V voltage rating and 1808 package footprint while offering ±10% tolerance instead of ±20%. This part is suitable for applications where tighter capacitance tolerance is required without increasing voltage stress. Packaging is Tape & Reel (TR) format.

1808GC332KAT1A is an upgraded substitute with doubled voltage rating (2000V). It provides the same 3300 pF capacitance and ±10% tolerance with enhanced voltage capability. The maximum thickness increases from 1.80mm to 2.20mm; this dimensional change must be verified against PCB layout constraints before selection. This part is recommended for applications operating at higher voltage levels or requiring additional voltage margin. Packaging is Tape & Reel (TR) format.

All three parts are active products with full RoHS3 compliance, REACH unaffected status, and EAR99 export classification. Selection between these parts depends on specific application voltage requirements and tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can 1808AC332KAT1A replace 1808AC332MAT1A directly?

A: Yes. Both parts have identical capacitance (3300 pF), voltage rating (1000V), package (1808), and temperature coefficient (X7R). The 1808AC332KAT1A offers improved tolerance (±10% vs ±20%). The primary difference is packaging format: 1808AC332MAT1A uses standard packaging while 1808AC332KAT1A is supplied in Tape & Reel format.

Q: What is the key difference between 1808AC332KAT1A and 1808GC332KAT1A?

A: The voltage rating differs: 1808AC332KAT1A is rated at 1000V while 1808GC332KAT1A is rated at 2000V. Both maintain 3300 pF capacitance and ±10% tolerance. The 2kV part has increased thickness (2.20mm vs 1.80mm), which may affect PCB layout compatibility.

Q: Is the thickness increase of 1808GC332KAT1A a concern?

A: The thickness increases from 1.80mm to 2.20mm. This 0.40mm difference must be evaluated against available PCB clearance and component placement constraints. Verify that the higher profile does not interfere with adjacent components or enclosure design.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts—1808AC332MAT1A, 1808AC332KAT1A, and 1808GC332KAT1A—are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity rating).

Q: Which part should be selected for a 2kV application?

A: The 1808GC332KAT1A is the appropriate choice for 2000V applications. It provides the required voltage rating while maintaining the same 3300 pF capacitance and X7R temperature stability. Confirm that the increased thickness (2.20mm) is compatible with your PCB design.

Q: Can 1808AC332MAT1A be used in place of 1808GC332KAT1A?

A: No. The 1808AC332MAT1A is rated at 1000V and cannot be substituted for applications requiring 2000V operation. Using an undersized voltage-rated component creates reliability risk.
