MAX552BEUB Equivalent & Substitute Parts
Part Overview
The MAX552BEUB is a 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring single-channel current output conversion. This component features an R-2R architecture with 1µs settling time and operates across a 2.7V to 3.6V supply range for both analog and digital domains.
The MAX552BEUB is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for legacy systems and new designs requiring compatible functionality.

Engineering Selection Recommendations
The MAX552BEUB+ is the direct functional equivalent of the MAX552BEUB. Both parts maintain identical electrical performance across all specified parameters, including resolution, settling time, supply voltage ranges, and accuracy specifications.
The primary distinction between these parts is product lifecycle status and regulatory compliance. The MAX552BEUB is classified as obsolete, while the MAX552BEUB+ maintains active production status. Additionally, the MAX552BEUB+ achieves ROHS3 compliance, whereas the original MAX552BEUB does not meet RoHS requirements.
For new designs and applications requiring long-term component availability, the MAX552BEUB+ is the appropriate selection. For legacy system maintenance where the original MAX552BEUB is specified, the MAX552BEUB+ provides electrical and mechanical compatibility without design modification.
Frequently Asked Questions (FAQ)
Q: Are MAX552BEUB and MAX552BEUB+ pin-compatible?
A: Yes. Both parts use the 10-pin TFSOP/MSOP package with identical pinout and electrical interface specifications. No PCB redesign is required for substitution.
Q: What is the difference between MAX552BEUB and MAX552BEUB+?
A: The parts are electrically identical across all functional parameters. The primary differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. ROHS3 compliant). The MAX552BEUB+ is packaged in tubes, while the original part packaging is unspecified.
Q: Can MAX552BEUB+ replace MAX552BEUB in existing designs?
A: Yes. The MAX552BEUB+ provides complete functional equivalence with identical electrical specifications, package configuration, and operating characteristics. No circuit modifications are necessary.
Q: Why is the MAX552BEUB obsolete?
A: Product obsolescence is determined by the manufacturer. The MAX552BEUB+ remains in active production and provides the same functionality, making it the recommended choice for ongoing applications.
Q: Are there any compliance differences between these parts?
A: Yes. The MAX552BEUB+ is ROHS3 compliant and REACH unaffected. The MAX552BEUB is RoHS non-compliant. For applications subject to RoHS regulations, the MAX552BEUB+ is required.
Q: What is the moisture sensitivity level for these parts?
A: Both MAX552BEUB and MAX552BEUB+ have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
