1808SC471MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1808SC471MAT1A is a 470 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V operation with X7R temperature coefficient characteristics. This Surface Mount MLCC (Multilayer Ceramic Capacitor) in 1808 (4520 Metric) package format is designed for general-purpose high-voltage applications requiring stable capacitance across the -55°C to 125°C operating range.

The part is currently Active in production status. Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, or enable voltage rating upgrades when circuit requirements permit higher voltage ratings within the same physical package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808SC471MAT1A is determined by the following mandatory parameters:

• Capacitance value: 470 pF (exact match required)
• Temperature coefficient: X7R (required for stable performance across operating range)
• Package / Case: 1808 (4520 Metric) (physical compatibility)
• Mounting type: Surface Mount, MLCC (assembly compatibility)
• Operating temperature range: -55°C to 125°C (functional equivalence)
• RoHS3 Compliance and MSL Level 1 (regulatory and handling compatibility)

Voltage rating may be equal to or higher than 1500V, as higher-rated components are backward compatible in circuits designed for lower voltages. Tolerance may vary (±10% or ±20%) based on application requirements. Manufacturer and packaging format (Tape & Reel vs. Cut Tape) do not affect electrical substitutability but may impact procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain electrical and mechanical compatibility with the 1808SC471MAT1A within the specified operating parameters. Selection should prioritize parts with Active product status for new designs.

1808GC471KAT1A (KYOCERA AVX, 2kV) and VPDP202W471K1GV001E (Johanson Dielectrics Inc., 2kV) are direct upgrades offering improved voltage margin while maintaining identical physical dimensions and thermal characteristics. Both are Active products with ROHS3 compliance.

KGM42CR73U471KY (KYOCERA AVX, 3kV) provides maximum voltage headroom for applications requiring enhanced overvoltage protection. This part exhibits slightly increased thickness (0.087" vs. 0.071") compared to the main part, which must be evaluated for PCB assembly clearance.

C4520X7R3D471K130KA (TDK Corporation, 2kV, ±10% tolerance) offers tighter tolerance specification and is Active for new designs. Physical dimensions differ slightly (0.177" L vs. 0.181" L, 0.059" thickness vs. 0.071"), requiring PCB layout verification.

C4520X7R3D471M130KA (TDK Corporation, 2kV, ±20% tolerance) carries "Not For New Designs" status and should be avoided for new product development despite electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute for the 1808SC471MAT1A?

A: Yes. Higher voltage ratings (2kV or 3kV) are electrically compatible in circuits designed for 1500V operation. The capacitor will operate within its rated specifications with additional voltage margin. Physical dimensions must be verified for PCB assembly compatibility.

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

A: Tolerance defines the allowable deviation from the nominal 470 pF capacitance value. ±20% permits values between 376 pF and 564 pF; ±10% permits values between 423 pF and 517 pF. Applications requiring tighter capacitance control should specify ±10% tolerance parts.

Q: Are all substitute parts available in the same packaging formats?

A: No. The main part is available in standard packaging; substitute parts are offered in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Packaging format affects procurement and assembly processes but does not impact electrical performance.

Q: Why does KGM42CR73U471KY have different physical dimensions?

A: The KGM42CR73U471KY (3kV rating) exhibits increased thickness (0.087" vs. 0.071") due to internal dielectric layer requirements for higher voltage rating within the same 1808 package footprint. PCB assembly clearance and component placement must be evaluated before substitution.

Q: Should I use C4520X7R3D471M130KA for new designs?

A: No. This part carries "Not For New Designs" product status. Use C4520X7R3D471K130KA (same manufacturer and voltage rating, Active status) or other Active-status alternatives for new product development.

Q: What does MSL Level 1 mean for handling and storage?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. These capacitors do not require special dry-pack storage or baking procedures before assembly, simplifying procurement and inventory management.
