Equivalent & Substitute Parts for 1812CC682KAT1A\SB

Part Overview

The 1812CC682KAT1A\SB is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 6800 pF, rated at 630V, and featuring X7R temperature coefficient characteristics. This Surface Mount MLCC (Multilayer Ceramic Capacitor) in 1812 (4532 Metric) package format 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 rating. Substitute parts are identified when equivalent electrical performance can be maintained while accommodating design flexibility, inventory availability, or voltage margin requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812CC682KAT1A\SB is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 6800 pF
• Tolerance: ±10%
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C to 125°C
• Mounting Type: Surface Mount, MLCC
• Package / Case: 1812 (4532 Metric)
• Physical Footprint: 0.181" L x 0.126" W (4.60mm x 3.20mm)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Voltage Rating: Equal to or greater than 630V

The substitute part 1812GC682KAT1A meets all mandatory parameters while providing an elevated voltage rating of 2000V (2kV), which exceeds the original specification and is therefore acceptable for direct substitution in applications where the circuit design permits higher voltage-rated components.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812CC682KAT1A\SB and 1812GC682KAT1A are active production parts from KYOCERA AVX with identical RoHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on circuit voltage requirements and available board space.

The 1812CC682KAT1A\SB is appropriate for applications with circuit voltages up to 630V. The 1812GC682KAT1A provides enhanced voltage margin at 2000V (2kV) and is suitable for high-voltage applications or designs requiring additional safety margin. The substitute part exhibits a maximum thickness of 0.110" (2.80mm) compared to 0.071" (1.80mm) for the main part; board layout clearance must be verified before substitution.

Frequently Asked Questions (FAQ)

Q: Can 1812GC682KAT1A be used as a direct replacement for 1812CC682KAT1A\SB?

A: Yes, provided that board layout accommodates the increased thickness of 0.110" (2.80mm) versus 0.071" (1.80mm). All electrical parameters, footprint dimensions, and compliance certifications are compatible.

Q: What is the primary difference between these two parts?

A: The rated voltage differs: 1812CC682KAT1A\SB is rated at 630V, while 1812GC682KAT1A is rated at 2000V (2kV). Both maintain identical capacitance, tolerance, temperature coefficient, and operating temperature range.

Q: Are there any compatibility concerns with the packaging format?

A: Both parts use identical 1812 (4532 Metric) Surface Mount MLCC packaging with matching footprint dimensions of 0.181" L x 0.126" W (4.60mm x 3.20mm). Soldering process parameters should remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry unlimited moisture sensitivity rating (MSL 1).

Q: What should be considered when selecting between these parts?

A: Circuit voltage requirements are the primary selection criterion. If the application operates at or below 630V, either part is acceptable. For applications exceeding 630V or requiring additional voltage safety margin, the 1812GC682KAT1A is required. Physical clearance for the increased thickness must be confirmed in the PCB layout.
