Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX535BCUA-T is based on matching the following critical parameters:

• 13-bit resolution with single DAC channel
• SPI serial data interface
• Buffered voltage output configuration
• External reference input capability
• 5V analog and digital supply voltages
• R-2R ladder architecture
• 8-pin surface mount package (8-TSSOP/8-MSOP)
• Operating temperature range 0°C ~ 70°C
• INL/DNL specification of ±1 LSB maximum

The MAX535BCUA+T meets all these criteria and is identified as a parametric equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX535BCUA+T is the direct parametric equivalent for the obsolete MAX535BCUA-T. Both parts share identical electrical specifications and mechanical packaging, ensuring pin-for-pin and functional compatibility.

The primary distinction between these parts is product status and regulatory compliance. The MAX535BCUA-T is obsolete with limited availability, while the MAX535BCUA+T is active in production with current inventory. The MAX535BCUA+T additionally meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant.

For new designs or production requiring compliance with current environmental regulations, the MAX535BCUA+T is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part provides equivalent performance given matching electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Are MAX535BCUA-T and MAX535BCUA+T pin-for-pin compatible?

A: Yes. Both parts use the 8-pin TSSOP/MSOP package with identical pinout and electrical interface specifications.

Q: What is the difference between the tube and tape & reel packaging?

A: Tube packaging (MAX535BCUA-T) is suitable for lower-volume applications and manual assembly. Tape & reel packaging (MAX535BCUA+T) is designed for automated pick-and-place assembly in high-volume production environments. The electrical and mechanical specifications remain identical.

Q: Can I use MAX535BCUA+T as a direct replacement for MAX535BCUA-T in existing designs?

A: Yes. The MAX535BCUA+T is a direct functional and electrical equivalent. No circuit modifications are required. Verify that your assembly process accommodates tape & reel packaging if transitioning from tube packaging.

Q: What does RoHS3 compliance mean for the MAX535BCUA+T?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials in electrical and electronic equipment. This is relevant for applications subject to EU environmental regulations or customer specifications requiring RoHS compliance.

Q: Are there any performance differences between these parts?

A: No. Both parts have identical electrical performance specifications including 13-bit resolution, 16µs settling time, ±1 LSB INL/DNL, and SPI interface characteristics.
