Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the AK4380VT is based on the following criteria derived from the provided specifications:

Primary Substitution Criteria:

• Manufacturer alignment: Asahi Kasei Microdevices (AKM) product family
• Functional category: Data Acquisition and Digital to Analog Conversion
• Active product status with current manufacturing support
• Compatible packaging and mounting technology

The AK4432VT qualifies as a manufacturer-recommended substitute based on these parameters. Both components originate from the same manufacturer's product portfolio and serve the Data Acquisition functional category. The AK4432VT maintains active product status with verified inventory availability, addressing the obsolescence constraint of the primary part.

Parameter Comparison

Engineering Selection Recommendations

Selection between the AK4380VT and AK4432VT should be based on the following factors:

AK4380VT Retention: Applicable only when existing inventory must be utilized or when system designs are locked to this specific component. Obsolete status limits future procurement options.

AK4432VT Selection: Recommended for new designs, system refreshes, or when long-term component availability is required. Active product status ensures manufacturing continuity. ROHS3 compliance satisfies current environmental and regulatory requirements. Higher inventory levels (9345 units) provide supply chain stability. Surface mount packaging with 16-TSSOP case enables modern PCB assembly processes.

The transition from AK4380VT to AK4432VT aligns with current manufacturing standards and regulatory compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Why is the AK4380VT classified as obsolete? A: The AK4380VT has reached end-of-life status within the manufacturer's product portfolio. Asahi Kasei Microdevices has transitioned this functional category to newer component designs, including the AK4432VT.

Q: What are the key differences between AK4380VT and AK4432VT? A: The primary differences are product status (Obsolete vs. Active), packaging specification (unspecified vs. 16-TSSOP), RoHS compliance (unspecified vs. ROHS3), and Moisture Sensitivity Level (MSL 1 vs. MSL 2). Both components serve the Data Acquisition category from the same manufacturer.

Q: Can AK4432VT be used as a direct replacement? A: The AK4432VT is the manufacturer-recommended substitute. Compatibility depends on your specific application requirements, including electrical specifications, package footprint, and thermal characteristics. Verify that the 16-TSSOP package and MSL 2 rating are compatible with your system design.

Q: What is the significance of MSL rating differences? A: MSL 1 (Unlimited) indicates no moisture sensitivity constraints. MSL 2 (1 Year) requires controlled storage conditions and limits shelf life to one year from the date of manufacture. This affects handling, storage, and assembly procedures.

Q: Is AK4432VT ROHS compliant? A: Yes, the AK4432VT is ROHS3 compliant, meeting current environmental and regulatory standards for electronic components in most markets.

Q: What packaging options are available for AK4432VT? A: The AK4432VT is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, both compatible with automated assembly processes.
