Engineering Selection Recommendations

For Standard Industrial Applications: TPS74701DRCR and TPS74701DRCT are direct electrical and mechanical equivalents to the discontinued TPS74701DRCRG4. Both parts maintain active product status with Texas Instruments and carry identical electrical specifications. Selection between these two standard-grade options depends on packaging requirements and inventory availability. TPS74701DRCR offers higher inventory (8730 Pcs) compared to TPS74701DRCT (2606 Pcs).

For Automotive Applications: TPS74701QDRCRQ1 is qualified to AEC-Q100 automotive standards and carries the automotive grade designation. This part maintains all electrical equivalence to the main part while providing automotive-grade reliability assurance. The higher inventory level (53698 Pcs) and active product status make this suitable for automotive designs requiring qualified components. Note the MSL rating difference (3 vs. 2) reflects automotive-grade moisture sensitivity specifications.

Product Status Consideration: All three substitute parts carry active product status, ensuring long-term availability and design support from Texas Instruments. The discontinued status of TPS74701DRCRG4 necessitates migration to one of these active alternatives for new designs and production continuity.
