Substitute Part Grouping Explanation

Substitution for the MAX642AC/D is based on alignment within the MAX642 base product family. The primary substitute, MAX642ACSA+, shares the same base product designation and manufacturer lineage. Substitution eligibility is determined by the following criteria:

• Identical base product number (MAX642)
• Matching manufacturer (Analog Devices Inc./Maxim Integrated)
• Compliance with ROHS3 and REACH requirements
• Equivalent MSL rating (1 - Unlimited)
• Active product status for continued availability

The MAX642ACSA+ variant represents the actively supported configuration within this product family, ensuring long-term supply chain viability and technical support.

Parameter Comparison

Engineering Selection Recommendations

The MAX642ACSA+ is the designated substitute for the obsolete MAX642AC/D based on product family continuity and regulatory compliance. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements. The MAX642ACSA+ carries active product status, providing assured availability and manufacturer support, whereas the MAX642AC/D is obsolete and subject to supply constraints.

Selection of MAX642ACSA+ is appropriate for new designs and production transitions requiring MAX642 series functionality. Packaging and mounting specifications differ between variants; verification of mechanical compatibility with existing PCB layouts is necessary prior to implementation.

Frequently Asked Questions (FAQ)

Q: Why is the MAX642AC/D listed as obsolete? A: The MAX642AC/D has reached end-of-life status with Analog Devices Inc./Maxim Integrated. The MAX642ACSA+ represents the active continuation within the MAX642 product family.

Q: Are MAX642AC/D and MAX642ACSA+ electrically interchangeable? A: Both components share the MAX642 base product designation and are manufactured by the same company. Electrical compatibility is determined by the specific functional parameters of your application. Detailed electrical specifications must be cross-referenced against your design requirements.

Q: What is the difference in packaging between these parts? A: The MAX642AC/D packaging is not specified in available documentation. The MAX642ACSA+ is supplied in Tube packaging with 8-SOIC (0.154", 3.90mm Width) case format in Surface Mount configuration.

Q: Can I use MAX642ACSA+ as a direct replacement on existing PCBs designed for MAX642AC/D? A: Mechanical compatibility depends on the original PCB layout specifications. The 8-SOIC package dimensions of MAX642ACSA+ must align with the footprint of the original component. PCB layout verification is required before implementation.

Q: What compliance certifications apply to both parts? A: Both MAX642AC/D and MAX642ACSA+ are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited), meeting current environmental and regulatory standards.
