DAC70508MRTER Equivalent & Substitute Parts

Part Overview

The DAC70508MRTER is a 14-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications. This device integrates 8 independent D/A converters in a 16-WQFN (3x3) surface mount package with an exposed pad. The part is currently in active production status with 3203 units available in new original stock condition.

Substitute parts are identified when they maintain identical electrical specifications, mechanical compatibility, and compliance certifications while differing only in packaging format or tape/reel configuration. This allows for flexible sourcing without redesign requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC70508MRTER are identified based on strict parametric equivalence. All substitute candidates must maintain identical specifications across the following critical parameters:

• Resolution: 14 bits
• Converter Count: 8 independent D/A converters
• Output Configuration: Voltage-buffered output
• Interface Protocol: SPI digital interface
• Reference Options: External and internal reference support
• Supply Voltage Ranges: Analog 2.7V–5.5V, Digital 1.7V–5.5V
• Linearity Performance: INL/DNL ±0.5 LSB
• Settling Time: 5µs typical
• Package Geometry: 16-WQFN (3x3) with exposed pad
• Thermal Range: -40°C to 125°C
• Compliance: ROHS3, REACH Unaffected

Substitution is permitted only when packaging format or tape/reel configuration differs while all electrical and mechanical parameters remain unchanged. The base product number DAC70508 identifies the core device architecture across all variants.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—DAC70508MRTER, DAC70508MRTET, and DAC70508ZRTET—are functionally equivalent and interchangeable at the circuit level. Selection between these variants is determined by procurement and assembly requirements rather than electrical performance.

DAC70508MRTER is supplied in tube packaging, suitable for manual assembly or low-volume production environments. DAC70508MRTET is supplied in tape and reel format, optimized for automated pick-and-place assembly in medium to high-volume manufacturing. DAC70508ZRTET is supplied in cut tape with Digi-Reel® packaging, providing flexibility for both manual and automated assembly workflows.

All variants maintain active production status with ROHS3 compliance and REACH unaffected certification, confirming regulatory compliance for industrial and commercial applications. Moisture sensitivity level 2 (1 Year) applies uniformly across all variants, requiring standard dry storage and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can DAC70508MRTET be used as a direct replacement for DAC70508MRTER in production?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only—DAC70508MRTER uses tube packaging while DAC70508MRTET uses tape and reel. No circuit modifications are required. Assembly process compatibility depends on your production equipment.

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

A: Tape & reel (TR) packaging supplies components on a continuous reel suitable for automated assembly machines. Cut tape (CT) & Digi-Reel® packaging provides components on cut tape segments, offering flexibility for both manual and automated processes. Both formats contain identical components.

Q: Are all three variants suitable for high-temperature applications?

A: Yes. All variants operate across the identical temperature range of -40°C to 125°C. Operating temperature capability is not a differentiating factor between these parts.

Q: Do packaging differences affect PCB layout or schematic design?

A: No. All variants use the identical 16-WQFN (3x3) package with exposed pad. PCB footprint, schematic symbol, and design requirements are identical across all three part numbers.

Q: What is the moisture sensitivity level, and does it differ between variants?

A: All variants carry MSL 2 (1 Year) rating. This indicates the component can be stored in standard dry conditions for up to one year without baking. Handling procedures are identical for all three part numbers.

Q: Are there any compliance or certification differences between these parts?

A: No. All three variants carry identical ROHS3 compliance and REACH unaffected status. Regulatory and environmental certifications are uniform across DAC70508MRTER, DAC70508MRTET, and DAC70508ZRTET.
