1808AA470MATME Equivalent & Substitute Parts

Part Overview

The 1808AA470MATME is a 47 pF ceramic capacitor rated at 1000V (1kV) with C0G/NP0 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 temperature extremes (-55°C to 125°C). The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and performance upgrades when required by application specifications or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1808AA470MATME is determined by the following allowable parameter variations:

Fixed Parameters (Must Match):

• Capacitance: 47 pF (exact match required)
• Temperature Coefficient: C0G/NP0 (required for stability)
• Package / Case: 1808 (4520 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount, MLCC (assembly compatibility)
• Operating Temperature Range: -55°C to 125°C (functional requirement)

Variable Parameters (Substitution Allowed):

• Voltage Rating: May be equal or higher than 1000V (1kV)
• Tolerance: May be tighter (±10%, ±5%) than ±20%
• Manufacturer: Different manufacturers acceptable if other parameters align
• Packaging Format: Tape & Reel (TR) acceptable as alternative to standard packaging

Substitute parts are grouped into two categories: direct equivalents (same voltage rating with improved tolerance) and upgraded alternatives (higher voltage rating with improved tolerance).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory conformance.

1808AA470KAT1A (KYOCERA AVX): Direct equivalent with improved tolerance (±10% vs. ±20%). Same voltage rating (1000V) and manufacturer. Suitable for applications requiring tighter capacitance tolerance without voltage upgrade requirements.

1808HA470JAT1A (KYOCERA AVX): Upgraded alternative with 3000V rating and ±5% tolerance. Recommended for applications requiring higher voltage margin or superior capacitance stability. Same manufacturer and package ensure seamless integration.

C4520C0G3F470K160KA (TDK Corporation): Upgraded alternative with 3000V rating and ±10% tolerance. Cross-manufacturer substitute from established supplier. Physical dimensions vary slightly (4.50mm L vs. 4.60mm L; 1.80mm thickness vs. 1.45mm thickness); verify PCB layout compatibility before selection.

VPDP102G470K1GV001E (Johanson Dielectrics Inc.): Direct voltage equivalent (1000V) with ±10% tolerance. Designed for SMPS filtering applications. Physical dimensions vary (4.70mm L, 2.03mm W, 2.16mm thickness); verify PCB layout and thermal environment compatibility before selection.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1808AA470MATME with a part having different capacitance value? A: No. Capacitance must remain at 47 pF. Different capacitance values alter circuit performance and are not acceptable substitutes.

Q: What is the significance of the C0G/NP0 temperature coefficient? A: C0G/NP0 designates a temperature coefficient of 0 ppm/°C, ensuring capacitance remains stable across the -55°C to 125°C operating range. This is a fixed requirement for all substitutes.

Q: Can I use a substitute with lower voltage rating than 1000V? A: No. Voltage rating must be equal to or higher than 1000V. Lower ratings compromise circuit safety and reliability.

Q: Are tighter tolerance parts (±10%, ±5%) direct replacements? A: Yes. Tighter tolerances are acceptable substitutes as they provide improved capacitance accuracy while maintaining all other electrical and mechanical specifications.

Q: What are the physical dimension differences between substitutes? A: C4520C0G3F470K160KA (TDK) measures 4.50mm L × 2.00mm W × 1.80mm thickness. VPDP102G470K1GV001E (Johanson) measures 4.70mm L × 2.03mm W × 2.16mm thickness. The main part measures 4.60mm L × 2.00mm W × 1.45mm thickness. Verify PCB footprint and clearance before substitution.

Q: Can I substitute across different manufacturers? A: Yes. All listed substitutes from KYOCERA AVX, TDK Corporation, and Johanson Dielectrics Inc. meet the required electrical and mechanical specifications. Verify supply chain availability and lead times.

Q: What does MSL 1 (Unlimited) mean? A: Moisture Sensitivity Level 1 indicates the component requires no special moisture control during storage, handling, or assembly. All substitutes carry the same MSL rating.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitutes maintain ROHS3 compliance, ensuring regulatory conformance for applications subject to RoHS directives.
