Texas Instruments
A pin-compatible buck regulator, but only suitable for loads under 1A. Requires review of load current.
Find and compare alternatives for the TPS563201DDCR, a 17V, 3A synchronous step-down converter. Review key parametric differences and potential risks before substitution.
Candidate current rating is only 1/3 of the target.
Package and pinout are compatible.
No direct, drop-in replacement for the TPS563201DDCR was identified. The closest candidate has a significantly lower current rating.
Downgrade to LMR50410XDBVR if load current is confirmed to be under 1A. Otherwise, search for another 3A buck converter.
The main risk is the severe output current downgrade from 3A to 1A with the LMR50410XDBVR, which could damage the part or cause system failure.

| Feature / factor | TPS563201DDCR | LMR50410XDBVR | Alt 2 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOT-23-6 | SOT-23-6 | SOT-23-6 — Package matches. | ||
| Pinout | Pin-compatible | Pin-compatible | Pin-compatible — Pin functions match based on datasheet review. | ||
| Current | 3A | 1A | 1A — Significantly lower output current. | ||
| Voltage | 4.5V to 17V | 4V to 36V | 4V to 36V — Wider input voltage range. | ||
| Frequency | 580kHz | 700kHz | 700kHz — Different frequency requires external component review. |
For low-current applications (<1A), the LMR50410XDBVR is a pin-compatible option but requires careful review. No direct 3A replacement was found in this batch; further sourcing is recommended.
