ISL5861IA Equivalent & Substitute Parts

Part Overview

The ISL5861IA is a 12-bit Digital to Analog Converter (DAC) manufactured by Renesas Electronics Corporation, designed for data acquisition applications. This single-channel DAC features current-unbuffered output with differential capability, parallel data interface, and support for both external and internal reference types. The device operates across a supply voltage range of 2.7V to 3.6V for both analog and digital domains, with an operating temperature range of -40°C to 85°C.

The ISL5861IA is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support legacy system maintenance and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL5861IA is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 12-bit resolution with 1 D/A converter
• Output Characteristics: Current-unbuffered output with differential capability
• Interface Type: Parallel data interface
• Reference Configuration: Support for both external and internal reference types
• Supply Voltage Compatibility: 2.7V to 3.6V for both analog and digital supplies
• Accuracy Specifications: INL/DNL of ±0.5 LSB
• Package Compatibility: 28-TSSOP surface mount package with identical physical dimensions
• Temperature Range: -40°C to 85°C operating range

The ISL5861IAZ meets all these criteria and is identified as a direct substitute for the ISL5861IA.

Parameter Comparison

Engineering Selection Recommendations

The ISL5861IAZ is a direct functional equivalent to the ISL5861IA with identical electrical and mechanical specifications. Both devices are classified as obsolete products from Renesas Electronics Corporation.

A key distinction exists in regulatory compliance: the ISL5861IAZ achieves ROHS3 compliance, whereas the ISL5861IA is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the ISL5861IAZ is the appropriate selection.

The ISL5861IAZ carries a Moisture Sensitivity Level (MSL) rating of 3 (168 hours), compared to the ISL5861IA's MSL rating of 1 (unlimited). This difference reflects handling and storage requirements; components with higher MSL ratings require controlled humidity environments during storage and have defined shelf-life windows after packaging seal opening.

Both parts share identical REACH and ECCN classifications, confirming equivalent regulatory treatment for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can the ISL5861IAZ be used as a direct replacement for the ISL5861IA in existing designs?

A: Yes. The ISL5861IAZ is electrically and mechanically identical to the ISL5861IA. All functional parameters, including resolution, output type, supply voltage ranges, accuracy specifications, and package dimensions, are equivalent. Direct substitution is supported without design modification.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The ISL5861IAZ is ROHS3 compliant, while the ISL5861IA is RoHS non-compliant. RoHS compliance restricts the use of hazardous substances in electrical and electronic equipment. For applications or markets requiring RoHS compliance, the ISL5861IAZ must be selected.

Q: How does the Moisture Sensitivity Level (MSL) difference affect component handling?

A: The ISL5861IA has MSL 1 (unlimited shelf life in sealed packaging), while the ISL5861IAZ has MSL 3 (168-hour shelf life after package opening). MSL 3 components require storage in controlled humidity environments and have defined time windows for use after the package seal is broken. Proper handling procedures must be followed to prevent moisture absorption and potential device failure.

Q: Are the package dimensions identical between ISL5861IA and ISL5861IAZ?

A: Yes. Both devices use the 28-TSSOP package with identical physical dimensions (0.173" width, 4.40mm). PCB footprints and assembly processes are interchangeable.

Q: What is the difference between the tube and other packaging formats?

A: The ISL5861IAZ is supplied in tube packaging, which is a standard format for surface mount components. Tube packaging affects handling, storage, and automated assembly processes but does not alter electrical or mechanical specifications.
