The TPS3897PDRYT: Without that thermal connection, the device derates significantly in high-ambient environments like an engine bay or industrial enclosure. The 6-SON package requires reflow or hot-air rework. Confirm your assembly house can handle this package before committing the BOM.
The part is ROHS3 compliant.
The TLV803EA29VDBZR is a peer Simple Reset/Power-On Reset supervisor, but it uses an Active Low open-drain output versus the TPS3897's Active High. The reset timeout is fixed at 130 ms minimum on the TLV803EA29VDBZR, while the TPS3897 offers an adjustable timeout. These differences mean a direct drop-in replacement requires board-level changes to the reset logic and timing capacitor.
