A pin-compatible upgrade with 3A output current, but requires review of external components due to a different switching frequency.
Find and evaluate replacements for the Texas Instruments TPS62A02DRLR, a 2A, 2.4MHz synchronous buck converter. This guide covers a pin-compatible upgrade path and other functional alternatives, detailing the risks and design changes required for each.
Most alternatives are not in a SOT-563 package and require a PCB redesign.
Switching frequency differences are common and require re-evaluation of external components.
Multiple alternatives exist from TI and other vendors, though may require design changes.
Direct replacement for TPS62A02DRLR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for TPS62A02DRLR, then review parametric alternatives for package and electrical fit.
The main risk when substituting is either mechanical or electrical. For most alternatives, the package is different, requiring a board redesign. For the pin-compatible option, the switching frequency differs, impacting external component selection and system efficiency.

| Feature / factor | TPS62A02DRLR | TLV62585PDRLR | TPS62826DMQR | TMI3113 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOT-563 | SOT563 | VSON-HR | TSOT23-6 | SOT563 / VSON-HR / TSOT23-6 — Package matches target.; TPS62826DMQR: Different package requires board redesign.; TMI3113: Different package requires board redesign. |
| Pinout | Pin-compatible | Pin-compatible per TI | - | - | Pin-compatible per TI — Target datasheet explicitly states pin compatibility. |
| Current | 2.0A | 3.0A | 3.0A | 3.0A | 3.0A — Higher output current capability.; TPS62826DMQR: Higher output current capability.; TMI3113: Higher output current capability. |
| Switching Frequency | 2.4 MHz | 1.5 MHz | 2.2 MHz | 1.0 MHz | 1.5 MHz / 2.2 MHz / 1.0 MHz — Lower frequency may require inductor/capacitor value changes.; TPS62826DMQR: Similar but different frequency.; TMI3113: Significantly different frequency requires new external components. |
| Voltage | 2.5V - 5.5V | 2.5V - 5.5V | 2.4V - 5.5V | 2.7V - 5.5V | 2.5V - 5.5V / 2.4V - 5.5V / 2.7V - 5.5V — Input voltage range matches.; TPS62826DMQR: Slightly wider input voltage range.; TMI3113: Higher minimum input voltage (2.7V vs 2.5V). |
Verified drop-in options for TPS62A02DRLR are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
