1812AC471MAT3A\SB Equivalent & Substitute Parts

Part Overview

The 1812AC471MAT3A\SB is a 470 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 1000V (1kV) operation with X7R temperature coefficient. This surface mount multilayer ceramic capacitor (MLCC) in 1812 (4532 Metric) package is designed for general purpose high voltage applications and maintains active product status with full ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent capacitance and package dimensions are maintained while allowing variations in voltage rating, temperature coefficient, and tolerance specifications that remain within acceptable electrical and mechanical parameters for this component category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812AC471MAT3A\SB is determined by the following mandatory parameters:

• Capacitance value: 470 pF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowed variations in substitute parts:

• Voltage - Rated: May be equal to or higher than 1000V
• Temperature Coefficient: May differ (C0G/NP0 or X7R acceptable)
• Tolerance: May be tighter (±5% or ±10% acceptable; ±20% is baseline)
• Thickness (Max): May be equal to or less than 0.071" (1.80mm)
• Manufacturer: May differ while maintaining equivalent electrical and mechanical specifications

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full ROHS3 compliance with unlimited moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental standards.

1812GA471JAT1A and CC1812JKNPOCBN471 offer tighter tolerance specifications (±5%) compared to the baseline ±20%, with C0G/NP0 temperature coefficient providing superior capacitance stability across the operating temperature range. Both are rated for 1000V or higher voltage operation.

1812GC471KAT1A maintains X7R temperature coefficient matching the original part while providing doubled voltage rating (2000V) with ±10% tolerance and identical thickness profile (0.071" / 1.80mm).

1812HC471KAT1A and KGM43ER73U471KV both provide tripled voltage rating (3000V) with X7R temperature coefficient and ±10% tolerance. KGM43ER73U471KV is designated as part of the KGM - HV series for high voltage applications.

CC1812JKNPOCBN471 from YAGEO offers dimensional variation with reduced thickness (0.059" / 1.50mm) and slightly smaller length (0.177" / 4.50mm), maintaining 1000V rating with C0G/NP0 coefficient and ±5% tolerance.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating than the original 1812AC471MAT3A\SB?

A: Yes. All listed substitute parts with 2000V or 3000V ratings are electrically compatible for applications originally specified for 1000V operation. Higher voltage rating provides additional design margin without affecting circuit performance at the original voltage specification.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R temperature coefficient allows ±15% capacitance variation across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with minimal capacitance change across temperature, typically ±30 ppm/°C. Selection depends on application sensitivity to capacitance drift over temperature.

Q: Are there physical compatibility concerns when substituting parts with different thickness specifications?

A: The original part has maximum thickness of 0.071" (1.80mm). Substitute parts with equal or lesser thickness (1812GC471KAT1A, 1812HC471KAT1A, KGM43ER73U471KV at 0.071" / 1.80mm, and CC1812JKNPOCBN471 at 0.059" / 1.50mm) are physically compatible. 1812GA471JAT1A with 0.087" (2.20mm) thickness requires clearance verification for board-level assembly.

Q: Does tolerance specification affect circuit performance?

A: Tolerance determines the acceptable capacitance range at nominal conditions. ±20% baseline tolerance allows 376 pF to 564 pF variation. Tighter tolerances (±5% or ±10%) reduce this range, providing more predictable circuit behavior in applications sensitive to capacitance variation.

Q: Can I substitute CC1812JKNPOCBN471 (YAGEO) for the original KYOCERA AVX part?

A: Yes. CC1812JKNPOCBN471 meets all mandatory substitution parameters: 470 pF capacitance, 1812 package, surface mount MLCC, -55°C to 125°C operating range, ROHS3 compliance, and MSL 1 rating. Dimensional differences (0.177" L vs 0.181" L, 0.059" thickness vs 0.071" thickness) are within acceptable mechanical tolerances for standard PCB assembly processes.
