1812SA102JAT3A\SB Equivalent & Substitute Parts

Part Overview

The 1812SA102JAT3A\SB is a 1000 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V (1.5kV) operation with C0G/NP0 temperature coefficient characteristics. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) 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 (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and voltage-rated options for circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1812SA102JAT3A\SB is determined by the following critical parameters:

• Capacitance Value: Must remain 1000 pF
• Tolerance: Must maintain ±5%
• Temperature Coefficient: Must be C0G/NP0 for stable performance across temperature range
• Package / Case: Must be 1812 (4532 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C to 125°C
• Voltage Rating: May be equal to or greater than 1500V

The identified substitute part KGM43FCG3D102JV meets all substitution criteria with an upgraded voltage rating of 2000V (2kV), providing enhanced voltage margin while maintaining identical capacitance, tolerance, temperature coefficient, package dimensions, and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SA102JAT3A\SB and KGM43FCG3D102JV are active production parts manufactured by KYOCERA AVX with identical ROHS3 compliance and REACH unaffected status. The substitute part KGM43FCG3D102JV provides a higher voltage rating of 2000V compared to the original 1500V specification, enabling use in circuits with elevated voltage stress margins. Both parts maintain identical electrical characteristics for capacitance, tolerance, and temperature coefficient performance. Selection between these parts depends on circuit voltage requirements: use the original part for 1500V-rated applications, or the substitute for designs requiring 2000V voltage headroom. Packaging format (Tape & Reel for the substitute) may influence procurement and assembly considerations.

Frequently Asked Questions (FAQ)

Q: Can KGM43FCG3D102JV replace 1812SA102JAT3A\SB in all applications?
