1808CA470MATME Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1808CA470MATME is a 47 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 630V 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 across an operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent capacitance values, package dimensions, and temperature coefficients are maintained while allowing variations in voltage rating, tolerance, and manufacturer specifications within acceptable engineering parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808CA470MATME is determined by the following criteria:

Fixed Parameters (Must Match):

• Capacitance: 47 pF
• Temperature Coefficient: C0G, NP0
• Package / Case: 1808 (4520 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C to 125°C
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Voltage Rating: May be equal to or greater than 630V
• Tolerance: May be tighter (lower) than ±20%
• Manufacturer: Different manufacturers acceptable
• Packaging Format: Tape & Reel acceptable

The substitute parts listed maintain all fixed parameters while offering enhanced voltage ratings (1000V or 3000V) and improved tolerances (±10% or ±5%), making them suitable for applications requiring higher voltage margins or tighter capacitance specifications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) ratings, ensuring compatibility with standard manufacturing and storage protocols. Selection among substitutes should be based on application voltage requirements and tolerance specifications:

1808AA470KAT1A (KYOCERA AVX): Suitable for applications requiring 1000V rating with improved ±10% tolerance. Maintains same manufacturer as primary part with higher voltage margin.

1808HA470JAT1A (KYOCERA AVX): Appropriate for high voltage applications requiring 3000V rating with tightest tolerance specification (±5%). Same manufacturer as primary part.

C4520C0G3F470K160KA (TDK Corporation): Provides 3000V rating with ±10% tolerance from alternative manufacturer. Physical dimensions vary slightly (4.50mm L x 2.00mm W, 1.80mm thickness maximum).

VPDP102G470K1GV001E (Johanson Dielectrics Inc.): Rated for 1000V with ±10% tolerance. Specified for SMPS filtering applications. Physical dimensions vary (4.70mm L x 2.03mm W, 2.16mm thickness maximum).

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating than the original 1808CA470MATME?

A: Yes. Higher voltage ratings (1000V or 3000V) are acceptable substitutes for the 630V rated part. The capacitor will function correctly in circuits designed for 630V operation, as it provides additional voltage margin without affecting capacitance value or temperature stability.

Q: What is the significance of tolerance differences between the main part and substitutes?

A: The main part specifies ±20% tolerance, while substitutes offer ±10% or ±5%. Tighter tolerances provide more precise capacitance values. If your circuit requires specific capacitance accuracy, select a substitute with appropriate tolerance specification.

Q: Are all substitute parts physically interchangeable with the 1808CA470MATME?

A: All parts share the 1808 (4520 Metric) package designation and identical length/width dimensions (approximately 4.60mm x 2.00mm). However, thickness varies: the main part and most substitutes measure 1.45mm maximum, while C4520C0G3F470K160KA measures 1.80mm and VPDP102G470K1GV001E measures 2.16mm. Verify PCB layout clearance for thicker alternatives.

Q: Does manufacturer selection affect circuit performance?

A: All listed manufacturers (KYOCERA AVX, TDK Corporation, Johanson Dielectrics Inc.) produce ROHS3 compliant components with identical electrical specifications for capacitance, temperature coefficient, and operating range. Selection may be based on supply availability, lead time, or established supplier relationships.

Q: Can I substitute the 1808CA470MATME in an existing design without circuit modification?

A: Yes, any listed substitute maintains the same capacitance value (47 pF), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). No circuit modifications are required. Verify physical clearance if selecting parts with increased thickness.
