1812AA162JAT1A\SB Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812AA162JAT1A\SB is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 1600 pF with 1000V (1kV) voltage rating and C0G/NP0 temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across temperature extremes (-55°C to 125°C) and high-voltage performance. The part is currently active in production with 1092 units in stock. Equivalent and substitute parts are identified to provide procurement flexibility, supply chain alternatives, and design redundancy when the primary part becomes unavailable or when inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the 1812AA162JAT1A\SB is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 1600 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 1000V (1kV) minimum (equal or higher acceptable)
• Temperature Coefficient: C0G/NP0 (exact match required for stability)
• Operating Temperature Range: -55°C to 125°C (equal or wider range acceptable)
• Package / Case: 1812 (4532 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (maintained across substitutes)

The substitute part C1812C162JDGAC7800 from KEMET meets all critical substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active product status and full compliance with ROHS3 and REACH regulations. The KEMET substitute C1812C162JDGAC7800 is designated as a manufacturer-recommended equivalent and carries 1898 units in current inventory. Selection between the primary part and substitute should be based on availability, lead time, and procurement cost. The KEMET part features lower ESL characteristics and reduced thickness (1.80mm vs. 2.20mm), which may provide advantages in high-frequency applications while maintaining full electrical and thermal equivalence. Both parts are suitable for direct substitution in general-purpose high-voltage ceramic capacitor applications.

Frequently Asked Questions (FAQ)

Q: Can C1812C162JDGAC7800 be used as a direct replacement for 1812AA162JAT1A\SB?

A: Yes. Both parts share identical electrical specifications (1600 pF, ±5%, 1000V, C0G/NP0) and package dimensions (1812/4532 Metric). Physical dimensions vary slightly (length 4.60mm vs. 4.50mm, thickness 2.20mm vs. 1.80mm), but these differences remain within standard PCB layout tolerances for 1812 package footprints.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, classified as EAR99, and share the same HTSUS code (8532.24.0020). Moisture Sensitivity Level is identical at MSL 1 (Unlimited).

Q: What is the significance of the lower ESL in the KEMET substitute?

A: Lower ESL (Equivalent Series Inductance) reduces impedance at higher frequencies, which can improve performance in RF and high-frequency filtering applications. However, for general-purpose DC and low-frequency applications, this difference is not functionally significant.

Q: Are there any thermal performance differences?

A: Both parts operate across the identical temperature range (-55°C to 125°C) with C0G/NP0 temperature coefficient, ensuring stable capacitance across the full operating spectrum. No thermal performance differentiation exists between the two parts.

Q: What packaging options are available for these parts?

A: The primary part (1812AA162JAT1A\SB) is available in standard packaging. The KEMET substitute (C1812C162JDGAC7800) is supplied in Tape & Reel (TR) format, which is standard for high-volume surface-mount assembly operations.
