Substitute Part Grouping Explanation

Substitution of the 1812Y0160104MXT is permissible when the following conditions are met:

Critical Parameters for Substitution:

• Capacitance value must remain 0.1 µF
• Package / Case must be 1812 (4532 Metric)
• Temperature Coefficient must be X7R
• Mounting Type must be Surface Mount, MLCC
• Operating Temperature Range must cover -55°C ~ 125°C
• Soft Termination feature must be present
• RoHS3 Compliance must be maintained

Allowable Variations:

• Voltage rating may be equal to or higher than 16V
• Tolerance may be equal to or tighter than ±20%
• Physical dimensions may vary within standard 1812 package specifications

The substitute part C1812X104K5RAC7800 from KEMET meets all critical parameters while providing a higher voltage rating (50V) and improved tolerance (±10%), making it suitable for direct replacement in applications where these enhanced specifications are acceptable.

Parameter Comparison

Engineering Selection Recommendations
