Substitute Part Grouping Explanation

The EW752E has one identified substitute within the AKM product portfolio: the EW750B. Substitution eligibility is determined by the following criteria:

Primary Substitution Criteria:

• Functional category: Magnetic Sensors / Digital Switch
• Manufacturer: Same source (Asahi Kasei Microdevices)
• Series alignment: Both components belong to the EW series
• Technology platform: Hall Effect-based switching architecture
• Output configuration: Open Collector output type

The EW750B is classified as an active product with current manufacturing status, making it suitable for replacing the obsolete EW752E in applications requiring magnetic field detection and digital switching functionality.

Engineering Selection Recommendations

Product Status Consideration: The EW752E is classified as obsolete. The EW750B is an active product with current manufacturing support from Asahi Kasei Microdevices. For new designs, repair operations, or long-term system support, the EW750B is the appropriate selection due to its active production status and availability.

Compliance and Certification: The EW750B carries ROHS3 compliance certification and is classified under ECCN EAR99, indicating standard commercial availability without export restrictions. The component meets moisture sensitivity requirements at MSL Level 1, suitable for standard storage and handling conditions.

Inventory Availability: Both components maintain adequate stock levels. The EW750B provides 1018 units of new original inventory, supporting immediate procurement for replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the EW750B directly replace the EW752E in existing circuit designs?

A: The EW750B is the manufacturer-identified substitute for the EW752E. Both components function as Hall Effect-based digital switches within the AKM EW series. Compatibility depends on the specific electrical and mechanical requirements of the application circuit. The EW750B features a 3-SIP package configuration with through-hole mounting, open collector output, and operates across a 3V to 26.4V supply voltage range.

Q: What is the significance of the EW750B's 3-SIP package designation?

A: The 3-SIP (3-pin Single In-line Package) is a through-hole mounting configuration. This package type determines PCB layout, footprint requirements, and mechanical integration. Designs originally using the EW752E must accommodate this specific package geometry for successful substitution.

Q: Are there electrical parameter differences between the EW752E and EW750B?

A: The EW750B specifications include defined electrical parameters: supply voltage range of 3V to 26.4V, maximum supply current of 6mA, maximum output current of 10mA, and sensing characteristics of 10mT trip threshold with 2.5mT release threshold. The EW752E detailed electrical parameters are not provided in the available documentation. Detailed electrical comparison requires access to complete EW752E datasheets.

Q: What does the EW750B's "Unipolar Switch" designation mean?

A: Unipolar switching indicates the sensor responds to magnetic fields of a single polarity (South Pole in this case). This differs from bipolar sensors that respond to both north and south pole fields. Application requirements must match this unipolar characteristic for proper operation.

Q: Is the EW750B suitable for high-temperature applications?

A: The EW750B operates across an ambient temperature range of -40°C to 115°C (TA). Applications requiring operation outside this range are not supported by this component.

Q: What is the ROHS3 compliance status of the EW750B?

A: The EW750B is ROHS3 compliant, indicating compliance with the Restriction of Hazardous Substances Directive. This certification confirms the component meets environmental and material composition standards for commercial and industrial applications.
