EW403 Equivalent & Substitute Parts

Part Overview

The EW403 is a magnetic switch integrated circuit manufactured by Asahi Kasei Microdevices (AKM), classified as a digital switch within the magnetic sensors category. This component is currently obsolete, which necessitates identification of active equivalent parts for ongoing design requirements and component sourcing. The EW403 remains available in inventory (1121 pcs new original stock), but its obsolete status requires engineers to evaluate suitable alternatives for new designs and long-term supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EW403 is determined by alignment across the following critical parameters:

• Manufacturer continuity: Parts sourced from the same manufacturer (Asahi Kasei Microdevices/AKM) ensure design compatibility and supply chain consistency
• Functional classification: Both the main part and substitute must operate as digital switches within the magnetic sensors category
• Moisture sensitivity: MSL rating of 1 (Unlimited) indicates no moisture-related handling restrictions; substitute parts must maintain this or equivalent rating
• Product status: Active status of substitute parts ensures long-term availability and ongoing manufacturer support

The EW610 meets all substitution criteria as an active magnetic sensor digital switch from the same manufacturer with identical MSL classification.

Parameter Comparison

Engineering Selection Recommendations

The EW610 is the manufacturer-recommended substitute for the obsolete EW403. Both components share identical functional classification as magnetic sensor digital switches and equivalent moisture sensitivity ratings. The EW610 carries active product status, ensuring continued manufacturer support and supply availability. The EW610 additionally provides ROHS3 compliance certification, meeting current environmental and regulatory standards for component manufacturing. Selection of the EW610 aligns with long-term design sustainability and regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the EW610 directly replace the EW403 in existing designs? A: The EW610 is the manufacturer-recommended substitute and shares the same functional classification (magnetic sensor digital switch) and moisture sensitivity rating. Verification of electrical and mechanical compatibility with your specific application is required before implementation.

Q: What is the significance of the obsolete status of the EW403? A: Obsolete status indicates the manufacturer has discontinued production and support. While existing inventory remains available, new designs should transition to active alternatives such as the EW610 to ensure long-term supply chain viability.

Q: Does the EW610 meet current regulatory requirements? A: The EW610 carries ROHS3 compliance certification, meeting current environmental and regulatory standards. The EW403 compliance status is not specified in available documentation.

Q: Are there packaging differences between the EW403 and EW610? A: Packaging information is not specified for either component in the provided data. Consult detailed datasheets or contact the manufacturer for specific package specifications.

Q: What is MSL 1 (Unlimited) and why does it matter? A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has no moisture-related handling restrictions during storage, transport, or assembly. Both the EW403 and EW610 share this rating, eliminating moisture sensitivity as a substitution constraint.
