Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC70504RTER are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain identical:

• Resolution: 14-bit digital-to-analog conversion
• Channel Count: 4 independent D/A converters
• Output Configuration: Voltage output with buffering
• Interface Protocol: SPI serial communication
• Supply Voltage Ranges: Analog (2.7V ~ 5.5V) and Digital (1.7V ~ 5.5V)
• Accuracy Specifications: INL/DNL of ±0.5 LSB
• Conversion Architecture: R-2R ladder network
• Thermal Operating Range: -40°C ~ 125°C
• Physical Package: 16-WQFN with exposed pad, 3x3mm footprint
• Compliance Standards: ROHS3 and REACH requirements

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the DAC70504RTER and DAC70504RTET are active production parts from Texas Instruments with identical electrical specifications and package configurations. Selection between these parts should be based on inventory availability and procurement lead times. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications. The identical moisture sensitivity level (MSL 2, 1 Year) requires equivalent handling and storage protocols. No technical performance differentiation exists between these parts; substitution is direct and interchangeable at the circuit design level.

Frequently Asked Questions (FAQ)

Q: Can DAC70504RTET be used as a direct replacement for DAC70504RTER in production designs?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, resolution, channel count, interface protocol, supply voltage ranges, accuracy specifications, and package configuration. Direct substitution is supported without circuit modification.

Q: Are there any differences in the 16-WQFN package between these parts?

A: No. Both parts use the identical 16-WQFN (3x3mm) surface-mount package with exposed pad. PCB footprints, solder reflow profiles, and assembly processes are interchangeable.

Q: What determines whether a part can substitute for the DAC70504RTER?

A: Substitution eligibility is determined by matching all critical parameters: 14-bit resolution, 4-channel configuration, buffered voltage output, SPI interface, dual supply voltage ranges (2.7V-5.5V analog, 1.7V-5.5V digital), ±0.5 LSB accuracy, R-2R architecture, -40°C to 125°C operating range, and 16-WQFN package format.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts share identical moisture sensitivity level (MSL 2, 1 Year), requiring the same storage conditions, humidity control, and shelf-life management protocols.

Q: Are compliance certifications identical between DAC70504RTER and DAC70504RTET?

A: Yes. Both parts maintain ROHS3 compliance and REACH unaffected status, with identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
