Substitute Part Grouping Explanation
Substitution of the MAASE31LSB7225MTNA01 is determined by strict equivalence across the following critical parameters:
Electrical Parameters: Capacitance value of 2.2 µF, tolerance of ±20%, and voltage rating of 16V must be maintained. The X7R temperature coefficient ensures stable capacitance across the operating temperature range of -55°C to 125°C.
Mechanical Parameters: The 1206 (3216 Metric) package and surface mount MLCC mounting type are required for PCB compatibility. Physical dimensions of 0.126" L x 0.063" W and maximum thickness of 0.071" must be preserved.
Compliance & Certification: AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 are maintained across all substitutes.
The identified substitute part EMK316B7225MLHT meets all electrical, mechanical, and compliance requirements for direct substitution.
