Substitute Part Grouping Explanation

Substitute parts for the KAM32LR71H335KU are identified based on strict equivalence of the following critical parameters:

• Capacitance value: 3.3 µF
• Tolerance: ±10%
• Voltage rating: 50V
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°C
• Package type: 1210 (3225 Metric) surface mount
• Physical dimensions: 0.126" L x 0.098" W x 0.110" max thickness
• Compliance: AEC-Q200 qualification, ROHS3 compliance

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign or re-qualification, provided application-specific requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the KAM32LR71H335KU and KAF32LR71H335KU are active production parts from KYOCERA AVX with identical electrical and mechanical specifications. Both components carry AEC-Q200 automotive qualification and ROHS3 compliance certification, meeting the same regulatory and quality standards.

The KAF32LR71H335KU is part of the FLEXITERM® series and features soft termination technology, which may provide additional mechanical reliability in boardflex-sensitive applications. However, this distinction does not affect electrical performance or parametric equivalence.

Selection between these parts should be based on application requirements, supply chain availability, and any specific design considerations related to mechanical stress or flex tolerance. Both parts are suitable for direct substitution in automotive circuits requiring 3.3 µF capacitance at 50V with X7R stability.
