Engineering Selection Recommendations
The MAX517BCSA+T is the direct functional equivalent to the MAX517BCSA-T. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional interchangeability in circuit applications.
The primary distinction between these parts is product status and regulatory compliance. The MAX517BCSA-T is classified as obsolete, while the MAX517BCSA+T maintains active product status. Additionally, the MAX517BCSA+T achieves ROHS3 compliance, whereas the MAX517BCSA-T is RoHS non-compliant. For new designs and ongoing system support, the MAX517BCSA+T is the appropriate selection due to its active availability and regulatory alignment with current environmental standards.
The packaging difference (Tube for MAX517BCSA-T versus Tape & Reel for MAX517BCSA+T) reflects standard distribution formats and does not affect component functionality or performance.
Frequently Asked Questions (FAQ)
Q: Can the MAX517BCSA+T directly replace the MAX517BCSA-T in existing designs?
A: Yes. The MAX517BCSA+T is electrically and mechanically identical to the MAX517BCSA-T. Both components feature 8-bit resolution, single DAC channel, I2C interface, external reference input, 5V supply requirements, and 8-SOIC packaging. No circuit modifications are required for substitution.
Q: What is the difference between the MAX517BCSA-T and MAX517BCSA+T?
A: The components are functionally equivalent. The MAX517BCSA-T is obsolete, while the MAX517BCSA+T is active. The MAX517BCSA+T is ROHS3 compliant, whereas the MAX517BCSA-T is RoHS non-compliant. Packaging format differs: the MAX517BCSA-T is supplied in Tube format, and the MAX517BCSA+T is supplied in Tape & Reel format.
Q: Are there any performance differences between these parts?
A: No. Both parts share identical electrical specifications including 8-bit resolution, 6µs settling time, ±1.5 LSB INL and ±1 LSB DNL linearity, and 0°C to 70°C operating temperature range.
Q: Is the 8-SOIC package compatible with existing PCB layouts?
