Product Overview
S5MWB is an automotive grade MEMS acceleration sensor IC, widely used on vehicle ABS control computer boards. It detects longitudinal and lateral acceleration signals for anti‑lock braking, stability control and roll‑over protection systems. This multi‑pin metal shield SMD chip is a common failure component on ABS ECU, frequently replaced during auto electronic repair work. Compatible cross‑reference parts: S5MWE, S5MVA.
Core Advantages
Vehicle ABS Dedicated Sensing
Designed to collect X‑axis and Y‑axis acceleration data, providing critical input signal for vehicle stability and anti‑brake control unit.
Metal Shield Package

Frequently Asked Questions
Q1: What is S5MWB used for?
A1: It is a dual‑axis acceleration sensor chip mounted inside automotive ABS ECU, detecting longitudinal and lateral acceleration for vehicle stability control system.
Q2: Are S5MWB, S5MWE, S5MVA interchangeable?
A2: These three share identical package and pinout, they are cross‑compatible for most ABS board repair cases.
Q3: Can I directly solder it and finish repair?
A3: After chip soldering, vehicle diagnostic tool is mandatory to complete sensor calibration; otherwise ABS system will report fault codes.
Q4: Is S5MWB the same as S5MWB rectifier diode?
A4: No. Same marking name but completely different device. This S5MWB is MEMS acceleration sensor, not power rectifier diode, cannot cross‑use.
Q5: Can other brand accelerometer substitute S5MWB?
A5: General‑purpose MEMS accelerometers cannot be used. It is customized for specific ABS mainboard hardware, only S5MWB / S5MWE / S5MVA can be replaced.
Q6: How can I get more information or bulk quotation?
A6: Submit request via Quick Inquiry form. We provide stock status, chip photos and quotation within 24 hours.
