1808SC471KATME Equivalent & Substitute Parts

Part Overview

The 1808SC471KATME is a 470 pF ±10% 1500V (1.5kV) ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient and 1808 (4520 Metric) package configuration. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching or exceeding electrical specifications while maintaining mechanical compatibility within the 1808 package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808SC471KATME is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 470 pF
• Tolerance: ±10%
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C to 125°C
• Package / Case: 1808 (4520 Metric)
• Mounting Type: Surface Mount, MLCC
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Voltage Rating: Equal to or greater than 1500V (1.5kV)
• Physical Dimensions: Within 1808 package tolerance; thickness may vary based on voltage rating requirements

All identified substitute parts meet or exceed the voltage rating of the original part while maintaining identical capacitance, tolerance, temperature coefficient, and compliance certifications. Substitutes are grouped by voltage rating upgrade level.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance and REACH unaffected status, matching the regulatory and environmental requirements of the original 1808SC471KATME.

Voltage Rating Upgrade Considerations:

1808GC471KAT1A, C4520X7R3D471K130KA, and VPDP202W471K1GV001E provide 2000V (2kV) rating, representing a 33% voltage margin increase over the original 1500V specification. KGM42CR73U471KY provides 3000V (3kV) rating, representing a 100% voltage margin increase.

Manufacturer Availability:

KYOCERA AVX substitutes (1808GC471KAT1A and KGM42CR73U471KY) maintain original manufacturer continuity. TDK Corporation (C4520X7R3D471K130KA) and Johanson Dielectrics Inc. (VPDP202W471K1GV001E) provide cross-manufacturer alternatives with equivalent electrical and mechanical specifications.

Packaging Considerations:

1808GC471KAT1A and VPDP202W471K1GV001E are supplied in Tape & Reel (TR) format. KGM42CR73U471KY is supplied in Tape & Reel (TR) format. C4520X7R3D471K130KA is supplied in Cut Tape (CT) & Digi-Reel® format. Original 1808SC471KATME packaging format is not specified in available data.

Frequently Asked Questions (FAQ)

Q: Can 1808GC471KAT1A be used as a direct replacement for 1808SC471KATME?

A: Yes. 1808GC471KAT1A matches all mandatory parameters (470 pF capacitance, ±10% tolerance, X7R temperature coefficient, -55°C to 125°C operating range, 1808 package, ROHS3 compliance, MSL 1) and exceeds the voltage rating (2000V vs. 1500V). The higher voltage rating provides additional design margin without affecting circuit performance.

Q: What is the difference between the KYOCERA AVX substitutes?

A: 1808GC471KAT1A provides 2000V (2kV) rating with 0.071" maximum thickness. KGM42CR73U471KY provides 3000V (3kV) rating with 0.087" maximum thickness. Both maintain identical capacitance and tolerance specifications. The thickness difference reflects the higher voltage rating requirement.

Q: Are there dimensional differences between substitute parts?

A: All parts conform to the 1808 (4520 Metric) package with length 0.181" (4.60mm) and width 0.079" (2.00mm). Thickness varies: 1808SC471KATME and 1808GC471KAT1A are 0.071" (1.80mm); KGM42CR73U471KY is 0.087" (2.21mm); C4520X7R3D471K130KA is 0.059" (1.50mm); VPDP202W471K1GV001E is 0.085" (2.16mm). Verify PCB layout clearance for thickness-sensitive applications.

Q: Can KGM42CR73U471KY be used in applications requiring only 1500V?

A: Yes. KGM42CR73U471KY is rated for 3000V and operates safely at lower voltages. The higher voltage rating does not degrade performance in lower-voltage applications.

Q: What is the difference between TDK and Johanson Dielectrics substitutes?

A: C4520X7R3D471K130KA (TDK) and VPDP202W471K1GV001E (Johanson) both provide 2000V (2kV) rating with 470 pF capacitance and X7R temperature coefficient. C4520X7R3D471K130KA has minimum thickness (0.059" / 1.50mm) and Cut Tape packaging. VPDP202W471K1GV001E has 0.085" (2.16mm) thickness and Tape & Reel packaging. Both are ROHS3 compliant with MSL 1.

Q: Are all substitute parts suitable for SMPS filtering applications?

A: VPDP202W471K1GV001E is specifically designated for SMPS filtering applications. All other parts are rated for general-purpose applications. Verify application-specific requirements with circuit design specifications.
