Pin-compatible alternative with slightly lower output current and temperature range.
TPS54360DDAR is a robust 60V, 3.5A step-down converter from Texas Instruments, ideal for high-voltage industrial applications. Finding a substitute requires careful matching of its wide input voltage range and high operating temperature.
Mismatches in input voltage, output current, and temperature are common and require careful review.
The HSOIC-8 package is standard and pinouts are often shared within the TI product family.
While many TI parts are available, specific automotive or industrial grades can face allocation.
Direct replacement for TPS54360DDAR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
LMR16030PDDAR is the closest functional match, but requires verifying the 3A current and 125°C temperature are sufficient for the application.
The primary risk is finding a part that matches the target's 60V input and 150°C temperature rating; many alternatives fall short.

| Package | HSOIC (8) | HSOIC (8) | HSOIC (8) | HSOIC (8) — Package is form-factor and pin-count compatible.; LMR14050SQDDARQ1: Package is form-factor and pin-count compatible. | |
| Pinout | Pin-compatible | Pin-compatible | - | Pin-compatible — Datasheet review confirms pin-for-pin compatibility. | |
| Voltage | 4.5V to 60V | 4.3V to 60V | 4V to 40V | 4.3V to 60V / 4V to 40V — Input voltage range is compatible.; LMR14050SQDDARQ1: Maximum input voltage is significantly lower. | |
| Current | 3.5A | 3A | 5A | 3A / 5A — Lower output current capability requires design validation.; LMR14050SQDDARQ1: Higher output current capability. | |
| Temperature | -40°C to 150°C | -40°C to 125°C | -40°C to 125°C | -40°C to 125°C — Reduced maximum operating temperature.; LMR14050SQDDARQ1: Reduced maximum operating temperature. |
Verified drop-in options for TPS54360DDAR 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.
