DAC5571IDBVTG4 Equivalent & Substitute Parts

Part Overview

The DAC5571IDBVTG4 is an 8-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, designed for data acquisition applications requiring voltage output conversion. This device features I2C interface communication, buffered voltage output, and operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital supplies.

The DAC5571IDBVTG4 is currently discontinued at DiGi Electronics. Equivalent substitute parts are available in active product status with identical electrical and mechanical specifications, differing only in packaging and distribution format. These alternatives ensure design continuity and supply chain flexibility for applications requiring this 8-bit DAC functionality.

Substitute Part Grouping Explanation

Substitute parts for the DAC5571IDBVTG4 are determined by equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical specifications for resolution (8-bit), converter count (1), settling time (8µs), output type (voltage-buffered), interface protocol (I2C), supply voltage ranges (2.7V–5.5V for both analog and digital), linearity performance (INL/DNL ±0.5/±0.25 LSB), architecture (String DAC), and operating temperature range (-40°C to 105°C).

Mechanical Equivalence: All substitute parts use the same package type (SOT-23-6) and mounting method (surface mount), ensuring direct PCB compatibility without layout modifications.

Differentiation: Substitute parts differ only in packaging format and distribution method (cut tape, tape & reel, or tube), which do not affect electrical performance or functional compatibility. Product status variations (active vs. discontinued) reflect current availability and supply chain considerations.

Parameter Comparison

Engineering Selection Recommendations

DAC5571IDBVR is recommended for applications requiring cut tape or Digi-Reel packaging formats. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain stability. The cut tape format is suitable for lower-volume production runs and manual assembly processes.

DAC5571IDBVT is recommended for high-volume manufacturing environments utilizing automated tape & reel assembly equipment. This part also maintains active product status, providing consistent supply availability. The tape & reel format optimizes pick-and-place machine compatibility and reduces component handling costs in production environments.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original DAC5571IDBVTG4. Selection between DAC5571IDBVR and DAC5571IDBVT should be based solely on packaging and assembly process requirements, as all electrical and mechanical specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can DAC5571IDBVR or DAC5571IDBVT be used as direct replacements for DAC5571IDBVTG4?

A: Yes. All three parts are electrically and mechanically identical. They share the same 8-bit resolution, I2C interface, SOT-23-6 package, operating temperature range, and supply voltage specifications. Differences exist only in packaging format (tube vs. cut tape vs. tape & reel), which do not affect circuit functionality or PCB compatibility.

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

A: Cut tape (DAC5571IDBVR) provides components on individual tape segments, suitable for manual assembly and lower-volume applications. Tape & reel (DAC5571IDBVT) provides components on continuous reels optimized for automated pick-and-place assembly in high-volume production. Both formats contain identical components with identical electrical performance.

Q: Does the packaging format affect the component's electrical performance?

A: No. Packaging format is a distribution and assembly consideration only. The electrical specifications, performance characteristics, and functional behavior of DAC5571IDBVR and DAC5571IDBVT are identical to DAC5571IDBVTG4.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. DAC5571IDBVTG4, DAC5571IDBVR, and DAC5571IDBVT are all ROHS3 compliant and REACH unaffected, meeting equivalent regulatory standards.

Q: Why is DAC5571IDBVTG4 discontinued while the other variants remain active?

A: Product discontinuation typically reflects distribution and market availability decisions rather than technical obsolescence. The substitute parts (DAC5571IDBVR and DAC5571IDBVT) remain in active production status, providing equivalent functionality with improved supply chain availability.
