|---|---|---|---|---|
| FFF Compatibility | PowerSSO-36 package with 36 pins is footprint-incompatible with the 32-pin HSOP package of MC33879BPEK.Physical package body and lead pitch differ, requiring PCB layout redesign.Offers 8 configurable high/low-side channels controlled via SPI with comprehensive diagnostic protections, meeting the primary electrical features of the original part. | 28-pin SOIC package is footprint-incompatible with the 32-pin HSOP package.Smaller package body and different pin count require board redesign.Max output current is lower (800mA vs 1.2A) and load voltage range is narrower (9V to 18V vs 5.5V to 27.5V). | ||
 AI Summary | MC33879BPEK by NXP USA Inc.: Power Switch/Driver 1:1 N-Channel 1.2A 32-SOIC-EP. | The L9301-TR is an active, highly integrated octal configurable switch from STMicroelectronics designed for automotive and industrial applications. It serves as an excellent functional alternative with robust diagnostic features, although it requires a PCB layout redesign due to its 36-pin PowerSSO package.
| The L9848TR is an active octal configurable switch that supports SPI communication and flexible channel configurations. While it offers a more compact footprint, it has lower current capability and a narrower load voltage operating range.
