Magnetic Encoder KTH5701AQ2 Perfectly Replaces MLX90393
In the current electronic supply chain environment, the supply stability and cost control of key components have become the focus of R&D engineers. As a world-renowned 3-axis magnetic sensor, the MLX90393ELW-ABA-011-RE from Melexis is widely used in industrial control, automotive electronics and consumer electronics due to its high precision and flexibility. However, facing delivery fluctuations and cost pressure, it is particularly important to find a domestic alternative with comparable performance, pin-compatibility and stable supply.
The KTH5701AQ2 from CONNTEK is such a domestic 3-axis Hall sensor designed for high-performance applications. Verified by practical tests, it can seamlessly replace the MLX90393 in key parameters, functions and package, providing design engineers with a highly competitive second-source solution. As an authorized agent of CONNTEK, Mando Technology has sufficient stock and professional technical support. Engineers can call 15012905940 for sample applications and bulk purchases.

2. Core Advantages of KTH5701AQ2 as a Replacement
1. True Pin-to-Pin Compatibility
The KTH5701AQ2 uses a standard QFN-3×3-16L package, which is highly consistent with the MLX90393 in dimensions and pin definition. Engineers can replace the device directly on existing PCBs without layout modification, which is critical for projects requiring fast development cycles. For detailed pin comparison, contact Mando Technology at 15012905940.
2. Built-in CORDIC Algorithm Simplifies Software Development
Unlike conventional sensors that only output raw magnetic data, the KTH5701AQ2 integrates a high-efficiency CORDIC algorithm. It can directly output angle data on XY, XZ and YZ planes and supports absolute position detection. This greatly reduces the computing load of the host MCU and improves system response speed, ideal for real-time knob and joystick control.
3. Stronger Environmental Adaptability & Wide Voltage Range
The KTH5701AQ2 supports a wide operating voltage of 2.8V to 5.5V, with an IO voltage down to 1.8V. It works with both 3.3V and 5V systems, eliminating the need for extra level-shifting circuits. It also supports a temperature range of -40°C to +85°C, fully meeting strict industrial and automotive-grade requirements.
4. Rich Integrated Functions
In addition to 3-axis magnetic sensing, the KTH5701AQ2 integrates a key detection function that detects proximity between the magnet and the chip, and can be configured to trigger single measurements. This sensor-plus-key design saves BOM cost and PCB space.
Under the trend of domestic substitution, the CONNTEK KTH5701AQ2 proves that domestic sensors can fully satisfy high-end applications with high performance, compatibility and reliability. It not only mitigates supply risks of the MLX90393 but also helps customers reduce BOM costs and improve competitiveness through better cost-performance and local technical support.
