TLC7528IPWR Equivalent & Substitute Parts

Part Overview

The TLC7528IPWR is an 8-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, designed for data acquisition applications requiring dual current output channels. This component features an R-2R architecture with external reference capability and operates across a 5V to 15V supply range. The device is actively produced and maintains full RoHS3 compliance with unlimited moisture sensitivity rating.

Substitute parts are identified to address inventory availability, packaging preferences, or specific application requirements while maintaining functional equivalence within defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC7528IPWR is determined by the following core parameters:

• 8-bit resolution with dual D/A converter channels
• Current output configuration (unbuffered)
• Parallel data interface with external reference
• R-2R converter architecture
• 20-TSSOP package footprint (0.173" width, 4.40mm)
• Surface mount technology
• Active product status with RoHS3 compliance

The identified substitute parts (AD5428YRUZ and AD5428YRUZ-REEL7) satisfy all functional and mechanical requirements. Variations in supply voltage ranges, settling time, and temperature operating ranges do not preclude substitution when application specifications fall within the substitute part's rated parameters.

Parameter Comparison

Engineering Selection Recommendations

Both AD5428YRUZ variants are functionally equivalent to the TLC7528IPWR for applications where the supply voltage range of 2.5V to 5.5V encompasses the required operating point. The TLC7528IPWR supports extended supply voltages up to 15V; applications requiring this extended range must retain the original part number.

All three parts maintain active product status and full RoHS3 compliance. Selection between substitute options depends on packaging requirements: AD5428YRUZ is supplied in tube packaging, while AD5428YRUZ-REEL7 is available in cut tape with Digi-Reel format. The settling time difference (100ns versus 120ns) is not a substitution barrier when application timing specifications accommodate the longer settling window.

Frequently Asked Questions (FAQ)

Q: Can AD5428YRUZ replace TLC7528IPWR in all applications?

A: Substitution is valid when the application supply voltage operates within the 2.5V to 5.5V range. Applications requiring supply voltages above 5.5V or below 2.5V must use the TLC7528IPWR.

Q: What is the difference between AD5428YRUZ and AD5428YRUZ-REEL7?

A: Both parts are electrically identical. The difference is packaging format: AD5428YRUZ uses tube packaging, while AD5428YRUZ-REEL7 uses cut tape with Digi-Reel format. Selection depends on assembly line requirements and inventory management preferences.

Q: Does the 20ns settling time difference affect substitution compatibility?

A: The settling time difference (100ns for TLC7528IPWR versus 120ns for AD5428 variants) does not prevent substitution. Compatibility depends on whether the application timing specification accommodates 120ns settling time.

Q: Are all parts RoHS3 compliant?

A: Yes. TLC7528IPWR, AD5428YRUZ, and AD5428YRUZ-REEL7 are all RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts use identical 20-TSSOP package footprints (0.173" width, 4.40mm) and surface mount technology, enabling direct PCB substitution without layout modifications.
