1808AA471MATBE Equivalent & Substitute Parts Reference

Part Overview

The 1808AA471MATBE is a 470 pF ceramic capacitor rated for 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 variations. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design optimization when the primary part becomes unavailable or when alternative electrical characteristics better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1808AA471MATBE are qualified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Capacitance value: 470 pF (exact match required)
• Package / Case: 1808 (4520 Metric) form factor (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

Allowable Variations:

• Voltage rating: Equal to or greater than 1000V
• Temperature coefficient: C0G/NP0 or X7R (both acceptable for general-purpose applications)
• Tolerance: ±10% or ±20% (tighter tolerance acceptable)
• Manufacturer: Different manufacturers permitted

The two identified substitute parts (C4520X7R3A471K130KA and C4520X7R3D471K130KA) meet all primary matching criteria. Both are TDK Corporation products with X7R temperature coefficient, which provides broader temperature stability characteristics compared to C0G/NP0, making them suitable alternatives for the specified operating range.

Parameter Comparison

Engineering Selection Recommendations

Both TDK substitute parts are active production components with ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the primary part.

C4520X7R3A471K130KA Selection Criteria:

• Voltage rating matches primary part specification (1000V)
• Tighter tolerance (±10% vs ±20%) provides improved capacitance accuracy
• X7R temperature coefficient offers broader temperature stability
• Packaged in Tape & Reel format
• Smaller physical dimensions and reduced thickness may benefit space-constrained layouts

C4520X7R3D471K130KA Selection Criteria:

• Voltage rating exceeds primary part specification (2000V vs 1000V)
• Tighter tolerance (±10% vs ±20%) provides improved capacitance accuracy
• X7R temperature coefficient offers broader temperature stability
• Packaged in Cut Tape & Digi-Reel format
• Smaller physical dimensions and reduced thickness may benefit space-constrained layouts
• Higher voltage rating provides additional design margin for overvoltage protection

Selection between substitute parts depends on application voltage requirements and packaging logistics. Both parts maintain full compliance with the operating temperature range and environmental standards of the primary part.

Frequently Asked Questions (FAQ)

Q: Can C4520X7R3A471K130KA or C4520X7R3D471K130KA be used as direct replacements for 1808AA471MATBE?

A: Both TDK parts are functionally equivalent for applications requiring 470 pF capacitance in the 1808 package form factor. The X7R temperature coefficient provides equivalent or superior performance across the -55°C to 125°C operating range. Physical dimensions are slightly smaller, which may require PCB layout verification for tight spacing applications.

Q: What is the difference between C4520X7R3A471K130KA and C4520X7R3D471K130KA?

A: The primary difference is voltage rating: C4520X7R3A471K130KA is rated for 1000V, while C4520X7R3D471K130KA is rated for 2000V. Both share identical capacitance, tolerance, temperature coefficient, and package specifications. The 2kV-rated part provides additional voltage margin and may be selected for applications with potential overvoltage conditions or future design upgrades.

Q: Does the X7R temperature coefficient differ functionally from C0G/NP0 for this application?

A: X7R and C0G/NP0 are both suitable for general-purpose applications across the -55°C to 125°C range. C0G/NP0 provides superior capacitance stability with minimal variation across temperature. X7R permits slightly greater capacitance variation but remains within acceptable limits for most circuit designs. Application-specific requirements should determine the preferred temperature coefficient.

Q: Are the physical dimension differences between the primary part and substitutes significant?

A: The substitute parts are approximately 0.004" (0.10mm) shorter in length and 0.028" (0.70mm) thinner than the primary part. These differences are within standard 1808 package tolerances and should not impact PCB layout compatibility. Verification of clearance in space-constrained areas is recommended during design review.

Q: Do all three parts share the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processing.
