Key Parameters

Substitute Part Grouping Explanation

The AD7401YRWZ qualifies as a direct substitute for the AD7401YRW based on the following critical parameters:

Matching Parameters:

• Identical base product number (AD7401)
• Identical resolution: 16 bits
• Identical channel count: 1 channel
• Identical data interface: Serial
• Identical voltage supply source: Dual Supply
• Identical operating temperature range: -40°C ~ 105°C
• Identical mounting type: Surface Mount
• Identical package / case: 16-SOIC (0.295", 7.50mm Width)
• Identical supplier device package: 16-SOIC

Substitution Basis: The AD7401YRWZ maintains full electrical and mechanical compatibility with the AD7401YRW. Both components share identical functional specifications for isolated 16-bit serial data acquisition. The primary distinction is product status: AD7401YRWZ is active production, whereas AD7401YRW is obsolete.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: Use AD7401YRWZ. This component is in active production status and carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new product development.

For Existing System Support: AD7401YRWZ provides direct functional replacement for AD7401YRW in maintenance and repair applications. Both components are electrically and mechanically identical, ensuring drop-in compatibility within existing PCB layouts and system architectures.

Compliance Considerations: AD7401YRWZ includes ROHS3 compliance and REACH unaffected status, providing regulatory alignment for applications subject to environmental directives. The AD7401YRW, being obsolete, lacks current compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can AD7401YRWZ directly replace AD7401YRW in existing designs? A: Yes. Both components share identical electrical specifications, pin configurations, and package dimensions (16-SOIC). No circuit modifications are required.

Q: What is the difference between AD7401YRW and AD7401YRWZ? A: The primary differences are product status (obsolete vs. active) and compliance certifications. AD7401YRWZ includes ROHS3 compliance and carries a higher moisture sensitivity level (MSL 3 vs. MSL 1). Electrical and mechanical specifications are identical.

Q: Are there any voltage supply differences between these parts? A: Both components operate with dual supply voltage. AD7401YRW specifies 3V ~ 5.5V and 4.5V ~ 5.25V ranges. AD7401YRWZ specifies 3V ~ 5.5V and 5V. These ranges are compatible for standard dual-supply applications.

Q: What packaging options are available? A: Both parts are supplied in 16-SOIC surface mount packages with 0.295" (7.50mm) width. AD7401YRWZ is available in tube packaging; AD7401YRW packaging type is not specified.

Q: Is the AD7401YRWZ suitable for high-reliability applications? A: AD7401YRWZ meets ROHS3 compliance requirements and is in active production. Moisture sensitivity level MSL 3 (168 hours) requires standard handling procedures during assembly. Consult Analog Devices technical documentation for specific reliability ratings and application requirements.
