Substitute Part Grouping Explanation

Substitute parts for the GC321AD7LP103KX18J are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Capacitance: 10000 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 450V (exact match required)
• Temperature Coefficient: X7T (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Physical Dimensions: 0.079" L x 0.049" W, 0.039" max thickness (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• AEC-Q200 Automotive Rating (required for automotive applications)
• RoHS3 Compliance (required for regulatory compliance)
• MSL Level 1 (required for moisture sensitivity)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations
