Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS1203IPWR is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: 16-bit resolution at 40 kHz sampling rate
• Channel Configuration: Single-channel operation
• Data Interface: Serial communication protocol
• Supply Voltage Range: 4.75V to 5.25V single supply operation
• Package and Mounting: 8-TSSOP surface mount package with identical physical dimensions
• Electrical Compliance: RoHS3 compliance and MSL Level 1 rating

The ADS1202IPWR meets all substitution criteria as a manufacturer-recommended equivalent. Both devices share identical electrical specifications for resolution, sampling rate, channel count, data interface, supply voltage, package type, and compliance certifications. The primary distinction is product status and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The ADS1202IPWR is the appropriate substitute for the obsolete ADS1203IPWR based on the following engineering criteria:

Product Status and Supply Chain: The ADS1202IPWR maintains Active product status with significantly higher inventory availability (2876 pieces in stock versus 844 pieces for the ADS1203IPWR). This ensures reliable long-term supply for new designs and production continuity.

Electrical and Functional Equivalence: Both devices are electrically identical across all critical data acquisition parameters: 16-bit resolution, 40 kHz sampling rate, single-channel configuration, serial data interface, and 4.75V to 5.25V supply voltage operation.

Compliance and Environmental Ratings: Both parts maintain ROHS3 compliance and MSL Level 1 moisture sensitivity ratings, ensuring equivalent reliability and environmental performance in manufacturing and field deployment.

Operating Temperature Consideration: The ADS1202IPWR specifies an operating temperature range of -40°C to 85°C, compared to -40°C to 125°C for the ADS1203IPWR. Applications requiring operation above 85°C must evaluate thermal requirements against the substitute device's maximum rated temperature.

Package Compatibility: Identical 8-TSSOP package specifications ensure direct physical and electrical compatibility on existing printed circuit board layouts without design modification.

Frequently Asked Questions (FAQ)

Q: Can the ADS1202IPWR directly replace the ADS1203IPWR in existing designs?

A: Yes. The ADS1202IPWR is electrically and functionally equivalent across all data acquisition parameters: 16-bit resolution, 40 kHz sampling rate, single-channel operation, serial interface, and 4.75V to 5.25V supply voltage. The identical 8-TSSOP package permits direct board-level substitution without layout modification.

Q: What is the primary difference between these two parts?

A: The ADS1203IPWR is Obsolete with an operating temperature range of -40°C to 125°C. The ADS1202IPWR is Active with an operating temperature range of -40°C to 85°C. For applications operating above 85°C, thermal performance must be evaluated against the substitute device's maximum rated temperature.

Q: Are there any compliance or certification differences?

A: No. Both the ADS1203IPWR and ADS1202IPWR maintain identical ROHS3 compliance status and MSL Level 1 moisture sensitivity ratings, ensuring equivalent environmental and manufacturing performance.

Q: Why is the ADS1202IPWR recommended as a substitute?

A: The ADS1202IPWR is the manufacturer-recommended equivalent with Active product status and superior inventory availability. It provides design continuity and supply chain reliability for applications currently using the obsolete ADS1203IPWR.

Q: Are there any design considerations for substitution?

A: Verify that your application's maximum operating temperature does not exceed 85°C. If operation above 85°C is required, the ADS1203IPWR's extended temperature range to 125°C may be necessary. All other electrical and mechanical parameters are identical, requiring no design changes.
