HUAXIN
A low-power functional alternative in the same SOT-23 package, but with a narrower voltage range.
HX6383EST is a low-power, omnipolar Hall effect switch in a SOT-23 package. When seeking alternatives, focus on candidates with matching push-pull outputs, omnipolar sensing, and compatible voltage ranges.
Voltage range and magnetic sensitivity differ and must be verified for the application.
Strong candidates share the same SOT-23 package, but pinout must be confirmed.
These are simple hardware components with no associated firmware.
No confirmed direct drop-in replacement exists. HX6701KSO and SM353LT are strong functional alternatives that require engineering review due to differences in voltage range and sensor technology.
Review HUAXIN HX6701KSO and Honeywell SM353LT. Both are strong candidates with lower power consumption.
The primary risk is the slightly narrower supply voltage range of the alternatives (e.g., 5.5V max vs. 6V), which may not be suitable for all designs.

| Feature / factor | HX6383EST | HX6701KSO | SM353LT | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOT-23 | SOT-23 | SOT-23 | SOT-23 — Package matches.; SM353LT: Package matches. | |
| Output Type | Push-Pull | Push-Pull | Push-Pull | Push-Pull — Output type matches.; SM353LT: Output type matches. | |
| Voltage | 1.65V to 6V | 1.8V to 5.5V | 1.65V to 5.5V | 1.8V to 5.5V / 1.65V to 5.5V — Slightly narrower voltage range.; SM353LT: Slightly lower max voltage. | |
| Current | 5 µA | 0.16 µA | 310 nA | 0.16 µA / 310 nA — Significantly lower power consumption.; SM353LT: Significantly lower power consumption. | |
| Technology | Hall Effect | TMR | Magnetoresistive | TMR / Magnetoresistive — Different sensor technology may affect magnetic response.; SM353LT: Different sensor technology may affect magnetic response. |
HX6701KSO and SM353LT are strong functional alternatives. Both offer lower power consumption in the same SOT-23 package, but require review of their slightly different voltage ranges and sensor technologies.
