Substitute Part Grouping Explanation

Substitution of the MAX543BC/D is based on the following critical parameters that must align across parts:

• Resolution: 12-bit conversion capability
• Manufacturer: Analog Devices Inc./Maxim Integrated (same product family)
• Base Product Number: MAX543 series
• Data Interface: Serial protocol compatibility
• Output Type: Current-unbuffered output configuration
• RoHS & Environmental Compliance: ROHS3 Compliant, REACH Unaffected status
• Moisture Sensitivity: MSL 1 (Unlimited)

The MAX543BCSA+ is qualified as a direct substitute based on identical resolution, manufacturer lineage, base product number alignment, and matching compliance certifications. The primary distinction is packaging format and active product status.
