Substitute Part Grouping Explanation

Substitution of the TPS2058DR is determined by strict equivalence across the following critical parameters:

• Output Configuration & Topology: High-side N-Channel switching with 2 x 1:2 input-to-output ratio and 4 total outputs
• Electrical Performance: 250mA maximum output current, 80mOhm typical on-resistance, 2.7V to 5.5V load voltage range
• Fault Protection Architecture: Current limiting (fixed), over-temperature protection, and UVLO (Under-Voltage Lock-Out)
• Package Compatibility: 16-SOIC surface-mount package with identical physical dimensions (0.154", 3.90mm width)
• Environmental & Compliance Standards: ROHS3 compliance, MSL Level 1, operating temperature range 0°C to 85°C

The TPS2058AD meets all substitution criteria as a direct functional equivalent with identical electrical specifications and package footprint.
