Substitute Part Grouping Explanation

Substitution eligibility for the TPS62301DRCRG4 is determined by strict equivalence across the following critical parameters:

Topology & Function: Buck (step-down) switching regulator
Output Voltage: Fixed 1.5V
Output Current: 500mA
Input Voltage Range: 2.7V to 6V
Switching Frequency: 3MHz
Synchronous Rectification: Integrated
Package Type: 10-VFDFN Exposed Pad (10-VSON 3x3)
Operating Temperature Range: -40°C to 85°C
Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The TPS62301DRCR meets all substitution criteria. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the original part's standard packaging. Both parts share identical electrical specifications, thermal performance, and regulatory certifications.
