A functional alternative from a different vendor with higher power but in a larger 1206 package.
TAI-TECH's RLM10FTSMR010 is a 0.5W, 10mΩ current sense resistor in a compact 0805 package. While no direct drop-in replacements are listed, several functional alternatives with higher power ratings are available in larger packages, requiring a PCB layout modification.
All candidates have a different package size (1206/2512 vs 0805), requiring a mandatory PCB redesign.
Some alternatives have a weaker TCR, which may affect measurement accuracy in temperature-sensitive applications.
Multiple vendors offer functionally similar parts, though package and TCR may vary.
No, there are no pin-compatible, drop-in replacements for RLM10FTSMR010 in the provided list. All suitable alternatives require a change in the PCB layout due to a larger package size.
Use RLM12FTCMR010 or MFJ06HR010FT if a PCB layout change to a 1206 footprint is possible. They offer a power upgrade with matching electricals.
The primary risk is the physical package mismatch. All functional alternatives are in larger packages (1206 or 2512), making them incompatible with the existing 0805 footprint.

| Feature / factor | RLM10FTSMR010 | MFJ06HR010FT | RLM12FTCMR010 | FMF06FTHR010-LH | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0805 | 1206 | - | - | 1206 — Requires PCB layout change. |
| Power | 0.5 W | 1.0 W | - | - | 1.0 W — Higher power rating is a safe upgrade. |
| Resistance | 10 mΩ | 10 mΩ | - | - | 10 mΩ — matched |
| Tcr | ±50 ppm/℃ | ±50 ppm/℃ | - | - | ±70 ppm/℃ — Worse temperature stability. Verify application sensitivity. |
| Tolerance | ±1% | - | ±1% | - | ±1% — matched |
The best alternatives are RLM12FTCMR010 and MFJ06HR010FT. They match key electrical specs and offer a higher power rating, but require a PCB layout change from an 0805 to a 1206 package.
