MAX5250BCPP Equivalent & Substitute Parts
Part Overview
The MAX5250BCPP is a 10-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring four independent voltage output channels. This component features SPI data interface, external reference capability, and R-2R architecture with buffered voltage outputs. The MAX5250BCPP is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The primary substitute maintains functional equivalence while offering improved product status and compliance certifications.

Substitute Part Grouping Explanation
Substitution of the MAX5250BCPP is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for:
- Resolution: 10-bit conversion
- Channel count: 4 independent D/A converters
- Output configuration: Voltage-buffered topology
- Interface protocol: SPI serial communication
- Reference architecture: External reference input
- Timing performance: 10µs typical settling time
- Linearity: ± 1 LSB INL/DNL maximum
- Supply requirements: 5V analog and digital supplies
- Temperature range: 0°C to 70°C operation
- Physical form factor: 20-DIP package with through-hole mounting
The MAX5250BCPP+ meets all these criteria while offering improved product lifecycle status and enhanced compliance certifications.

Engineering Selection Recommendations
The MAX5250BCPP+ is the direct functional equivalent of the MAX5250BCPP, with identical electrical performance and mechanical compatibility. Selection of the MAX5250BCPP+ is supported by two primary engineering factors:
Product Lifecycle Status: The MAX5250BCPP+ maintains active product status with ongoing manufacturer support, whereas the MAX5250BCPP is classified as obsolete. Active status ensures continued availability and supply chain reliability.
Regulatory Compliance: The MAX5250BCPP+ achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The original MAX5250BCPP does not meet this compliance standard. Both parts maintain REACH Unaffected status and EAR99 export classification.
For new designs and system replacements, the MAX5250BCPP+ provides equivalent functionality with improved compliance posture and supply assurance.
Frequently Asked Questions (FAQ)
Q: Can MAX5250BCPP+ directly replace MAX5250BCPP in existing designs?
A: Yes. The MAX5250BCPP+ is electrically and mechanically identical to the MAX5250BCPP. All pin configurations, signal timing, supply requirements, and output characteristics are equivalent. Direct substitution is possible without circuit modification.
Q: What is the difference between MAX5250BCPP and MAX5250BCPP+?
A: The parts are functionally identical. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 Compliant vs. non-compliant). The "+" designation indicates the newer revision with improved compliance certifications.
Q: Are there packaging differences between these parts?
A: Both parts use 20-DIP through-hole packages with identical physical dimensions (0.300", 7.62mm). The MAX5250BCPP+ is supplied in tube packaging, while the original MAX5250BCPP packaging specification is not detailed.
Q: What are the critical parameters for DAC substitution?
A: For the MAX5250BCPP family, critical parameters include 10-bit resolution, 4-channel configuration, SPI interface, external reference input, 5V supply requirements, and 20-DIP through-hole package. Any substitute must match all these specifications.
Q: Is the MAX5250BCPP+ suitable for new product designs?
A: Yes. The MAX5250BCPP+ is the recommended choice for new designs due to active product status, ROHS3 compliance, and ongoing manufacturer support.
