DAC5578SRGET Equivalent & Substitute Parts

Part Overview

The DAC5578SRGET is an 8-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring voltage output conversion. This device features eight independent D/A converters in a 24-VQFN surface mount package with an exposed pad. The part is currently in active production status with 1071 units available in new original condition from inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DAC5578SRGET is determined by strict equivalence across the following critical parameters:

• Resolution: 8-bit conversion
• Converter Count: 8 independent D/A converters
• Output Configuration: Voltage output with buffering
• Interface Protocol: I2C digital communication
• Reference Architecture: External reference requirement
• Supply Voltage Range: 2.7V to 5.5V for both analog and digital supplies
• Accuracy Specifications: INL/DNL of ±0.01 LSB
• Thermal Performance: Operating range -40°C to 125°C
• Physical Form Factor: 24-VQFN package with exposed pad
• Regulatory Compliance: ROHS3 compliance and MSL 3 rating

The DAC5578SRGET and its identified substitute maintain identical electrical specifications and mechanical compatibility, differing only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel).

Parameter Comparison

Engineering Selection Recommendations

Both the DAC5578SRGET and DAC5578SRGER are active production devices from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on packaging and inventory requirements:

The DAC5578SRGET is supplied in Tape & Reel format, suitable for high-volume automated assembly operations. The DAC5578SRGER is supplied in Cut Tape and Digi-Reel format, appropriate for lower-volume applications or mixed component sourcing scenarios.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The MSL 3 rating (168 hours) applies to both variants, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Are DAC5578SRGET and DAC5578SRGER electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 8-bit resolution, 8 converter channels, 12µs settling time, I2C interface, and ±0.01 LSB accuracy. They operate across the same supply voltage range (2.7V to 5.5V) and temperature range (-40°C to 125°C).

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. DAC5578SRGET uses Tape & Reel packaging, while DAC5578SRGER uses Cut Tape and Digi-Reel packaging. Both use the identical 24-VQFN surface mount package with exposed pad.

Q: Can I substitute DAC5578SRGER for DAC5578SRGET in my design?

A: Yes, from an electrical and mechanical standpoint. Both parts are pin-compatible, functionally equivalent, and meet the same performance specifications. Packaging format selection depends on your assembly process requirements.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL 3 moisture sensitivity ratings.

Q: Which part should I select for new designs?

A: Selection should be based on your procurement and assembly requirements. Choose Tape & Reel (DAC5578SRGET) for high-volume automated pick-and-place operations, or Cut Tape & Digi-Reel (DAC5578SRGER) for lower-volume or mixed sourcing scenarios.
