DAC8750IRHAR Equivalent & Substitute Parts

Part Overview

The DAC8750IRHAR is a 16-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring buffered current output. This single-channel DAC operates across a wide analog supply voltage range of 10V to 36V with digital supply flexibility from 2.7V to 5.5V, making it suitable for industrial and precision measurement systems. The device is currently in active production status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when identical electrical specifications, package geometry, and compliance certifications are maintained across different packaging or tape configurations.

Substitute Part Grouping Explanation

The DAC8750IRHAT qualifies as a parametric equivalent to the DAC8750IRHAR based on strict electrical and mechanical compatibility criteria. Both parts share identical specifications across all critical substitution parameters: 16-bit resolution, single-channel configuration, buffered current output topology, 25µs settling time, dual reference capability (external and internal), matching analog and digital supply voltage ranges, equivalent INL/DNL performance, identical package geometry (40-VFQFN with exposed pad), and surface mount mounting type. The distinction between these part numbers reflects packaging configuration only—the DAC8750IRHAR is supplied in standard packaging while the DAC8750IRHAT is supplied in tape and reel format. Both maintain identical product status (active), RoHS3 compliance, and MSL rating. Substitution is valid when application requirements do not mandate a specific packaging format.

Engineering Selection Recommendations

Selection between DAC8750IRHAR and DAC8750IRHAT is determined by procurement and assembly process requirements rather than electrical performance. Both parts are manufactured by Texas Instruments and maintain active product status with full regulatory compliance (RoHS3 compliant, REACH unaffected). The DAC8750IRHAT in tape and reel format is suitable for high-volume automated assembly operations where continuous component feeding is required. The DAC8750IRHAR in standard packaging accommodates lower-volume production, prototyping, or manual assembly workflows. Moisture sensitivity level 3 (168 hours) applies uniformly to both configurations, requiring equivalent handling and storage protocols. No electrical performance differential exists between these part numbers; selection criteria are logistics-based only.

Frequently Asked Questions (FAQ)

Q: Are DAC8750IRHAR and DAC8750IRHAT electrically interchangeable?

A: Yes. Both parts are identical in all electrical specifications including resolution (16-bit), output configuration (buffered current), settling time (25µs), supply voltage ranges (analog 10V–36V, digital 2.7V–5.5V), and performance metrics (±1 LSB INL/DNL). The part number suffix reflects packaging format only.

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

A: The DAC8750IRHAT is supplied in tape and reel (TR) packaging format, while the DAC8750IRHAR uses standard packaging. Both contain identical die and are housed in the same 40-VFQFN package with exposed pad.

Q: Can I substitute DAC8750IRHAT for DAC8750IRHAR in my design?

A: Substitution is valid from an electrical and mechanical standpoint. Verify that your assembly process can accommodate tape and reel format if switching to DAC8750IRHAT, or confirm standard packaging availability if switching to DAC8750IRHAR.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts carry MSL rating 3 (168 hours), requiring identical storage conditions and handling protocols to prevent moisture absorption.

Q: Are both parts RoHS compliant?

A: Yes. Both DAC8750IRHAR and DAC8750IRHAT are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the operating temperature range for these parts?

A: Both parts operate across -40°C to 125°C, supporting industrial and extended temperature applications.
