Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS8327IRSAT is determined by strict equivalence across the following critical parameters:

• 16-bit resolution
• 500 kSPS sampling rate
• Single input channel
• Differential and single-ended input support
• SPI digital interface
• SAR architecture
• External reference configuration
• 5V analog supply and 1.65V ~ 5.5V digital supply compatibility
• 16-VQFN Exposed Pad package (4x4 mm)
• Surface mount configuration
• -40°C ~ 85°C operating temperature range

All identified substitute parts maintain identical electrical and mechanical specifications. Differences exist only in product status, packaging format, and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

ADS8327IBRSAT is the manufacturer-recommended substitute. This part maintains active product status with Texas Instruments, ensuring ongoing technical support and long-term availability. It is supplied in Tape & Reel packaging format, suitable for high-volume production environments. All electrical and mechanical specifications are identical to the ADS8327IRSAT.

ADS8327IBRSAR is a parametric equivalent offering identical electrical and mechanical performance. This part also carries active product status and is supplied in Tape & Reel format. Selection between ADS8327IBRSAT and ADS8327IBRSAR should be based on packaging requirements and supplier availability, as both parts are functionally interchangeable.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original ADS8327IRSAT.

Frequently Asked Questions (FAQ)

Q: Can ADS8327IBRSAT and ADS8327IBRSAR be used interchangeably with ADS8327IRSAT?

A: Yes. Both substitute parts are parametrically equivalent across all critical electrical and mechanical specifications, including resolution, sampling rate, input configuration, supply voltages, operating temperature range, and package dimensions. Direct substitution is supported without circuit modification.

Q: What is the primary difference between the substitute parts?

A: The ADS8327IRSAT was supplied in tube packaging. Both ADS8327IBRSAT and ADS8327IBRSAR are supplied in Tape & Reel format, which is standard for production environments. The electrical and mechanical specifications are identical.

Q: Why is the ADS8327IRSAT listed as Obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued active manufacturing and support for this specific part number variant. The substitute parts (ADS8327IBRSAT and ADS8327IBRSAR) maintain active status and are recommended for new designs and ongoing production.

Q: Are there any compliance or certification differences?

A: No. All three parts maintain identical RoHS3 compliance, REACH unaffected status, MSL rating of 2 (1 Year), and equivalent regulatory certifications (ECCN: EAR99, HTSUS: 8542.39.0001).

Q: Which substitute should be selected for new production?

A: Either ADS8327IBRSAT or ADS8327IBRSAR is appropriate for new production. Selection should be based on supplier availability and internal packaging specifications. Both parts are functionally and mechanically identical.

Q: Is PCB layout modification required when substituting these parts?

A: No. All three parts use the identical 16-VQFN Exposed Pad package (4x4 mm) with surface mount configuration. PCB footprints and layout are directly compatible without modification.
