1808CC471MAT1A Equivalent & Substitute Parts

Part Overview

The 1808CC471MAT1A is a 470 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 630V with X7R temperature coefficient and ±20% tolerance. This surface mount multilayer ceramic capacitor (MLCC) in 1808 (4520 Metric) package is designed for general purpose high voltage applications across the -55°C to 125°C operating temperature range. The part is currently active and ROHS3 compliant with MSL 1 rating.

Substitute parts are necessary when higher voltage ratings, improved tolerance specifications, or alternative manufacturer sourcing is required for design optimization, supply chain flexibility, or performance enhancement in high voltage circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808CC471MAT1A is determined by the following critical parameters:

• Capacitance Value: Must be 470 pF (exact match required)
• Temperature Coefficient: Must be X7R (ensures stable capacitance across operating temperature range)
• Package / Case: Must be 1808 (4520 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Voltage Rating: Equal to or greater than 630V (higher ratings provide design margin)
• Tolerance: ±10% or ±20% acceptable (±10% provides tighter specification)
• RoHS / REACH Compliance: ROHS3 Compliant and REACH Unaffected required
• Moisture Sensitivity Level: MSL 1 required

Substitute parts are grouped by voltage rating upgrade levels: 1kV, 2kV, and 3kV ratings, each offering improved voltage margin over the original 630V specification.

Parameter Comparison

Engineering Selection Recommendations

For Active Designs (Recommended Substitutes):

1808GC471KAT1A (KYOCERA AVX, 2kV, ±10%) and C4520X7R3D471K130KA (TDK Corporation, 2kV, ±10%) are preferred substitutes. Both maintain active product status, offer 2kV voltage rating for enhanced design margin, and provide ±10% tolerance specification. These parts are suitable for new design implementations.

KGM42CR73U471KY (KYOCERA AVX, 3kV, ±10%) provides maximum voltage margin at 3kV rating and active status, appropriate for applications requiring highest voltage headroom.

C4520X7R3A471K130KA (TDK Corporation, 1kV, ±10%) offers minimum voltage upgrade with active status and ±10% tolerance, suitable for designs requiring modest voltage margin increase.

VPDP202W471K1GV001E (Johanson Dielectrics Inc., 2kV, ±10%) provides alternative manufacturer sourcing with 2kV rating and active status for supply chain diversification.

For Legacy or Constrained Designs:

C4520X7R3A471M130KA and C4520X7R3D471M130KA (TDK Corporation) carry "Not For New Designs" status and should be used only in existing production or legacy applications where substitution is not feasible. Both maintain ROHS3 compliance and MSL 1 rating.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity level consistent with the original part specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 1808CC471MAT1A with a lower voltage rated part?

A: No. Substitute parts must maintain equal or greater voltage rating than 630V. Lower voltage ratings do not meet the electrical requirements of the original specification.

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

A: Tolerance specifies the allowable capacitance deviation from the nominal 470 pF value. ±10% tolerance (47 pF to 517 pF range) provides tighter capacitance control compared to ±20% tolerance (376 pF to 564 pF range). Applications requiring precise capacitance values should specify ±10% tolerance substitutes.

Q: Are all substitute parts mechanically compatible with the original 1808 package?

A: All listed substitutes use the 1808 (4520 Metric) package designation. However, physical dimensions vary slightly between manufacturers. The original part measures 4.60mm × 2.00mm × 1.80mm (max thickness). Verify specific PCB layout requirements, particularly for higher voltage rated parts which may have increased thickness (up to 2.21mm for KGM42CR73U471KY).

Q: Why should I avoid parts marked "Not For New Designs"?

A: Parts with "Not For New Designs" status indicate manufacturer phase-out or obsolescence planning. These parts should be used only in existing production runs or legacy applications. New designs should specify active status parts to ensure long-term supply availability and manufacturer support.

Q: Can I use a 3kV rated part in place of the 630V original?

A: Yes. The KGM42CR73U471KY (3kV, ±10%) is electrically compatible and provides maximum voltage safety margin. Verify PCB layout accommodates the slightly increased thickness (2.21mm vs. 1.80mm original) before implementation.

Q: What is the significance of X7R temperature coefficient?

A: X7R temperature coefficient ensures capacitance stability across the -55°C to 125°C operating range with minimal variation. All substitute parts maintain X7R specification, guaranteeing consistent performance across the full temperature range.

Q: Are there manufacturer-specific considerations for substitution?

A: KYOCERA AVX, TDK Corporation, and Johanson Dielectrics Inc. are established manufacturers with equivalent quality and reliability standards. Selection may be based on supply availability, lead time, or existing supplier relationships. All listed parts maintain identical compliance certifications (ROHS3, REACH unaffected, MSL 1).
