ADS8371IPFBTG4 Equivalent & Substitute Parts

Part Overview

The ADS8371IPFBTG4 is a 16-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, part of the microPOWER™ series. This SAR (Successive Approximation Register) architecture device features a single differential input with parallel data interface, operating at 750k samples per second. The part is discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain full electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ADS8371IPFBTG4 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for direct substitution:

• 16-bit resolution
• 750k samples per second sampling rate
• Single differential input configuration
• Parallel data interface
• SAR architecture
• External reference type
• 5V analog supply voltage
• 2.7V ~ 5.25V digital supply voltage range
• -40°C ~ 85°C operating temperature range
• 48-TQFP (7x7) package
• Surface mount mounting type
• ROHS3 compliance
• MSL 2 rating

The substitute parts identified maintain identical specifications across all these parameters. Differences exist only in packaging format (Tape & Reel versus bulk) and product status (Active versus Discontinued).

Parameter Comparison

Engineering Selection Recommendations

Both ADS8371IPFBT and ADS8371IBPFBT are direct electrical and mechanical equivalents to the ADS8371IPFBTG4. The primary distinction is product status: both substitute parts are currently Active, whereas the original part is Discontinued at DiGi Electronics.

For new designs and production applications, either substitute part is suitable. ADS8371IPFBT is designated as the manufacturer-recommended substitute. ADS8371IBPFBT is classified as a parametric equivalent. Both parts carry identical ROHS3 compliance and MSL 2 ratings, ensuring compatibility with standard manufacturing and storage protocols.

The packaging format difference (Tape & Reel for substitutes versus bulk for the original) affects procurement and assembly logistics but does not impact electrical performance or board-level functionality.

Frequently Asked Questions (FAQ)

Q: Can ADS8371IPFBT and ADS8371IBPFBT be used interchangeably with ADS8371IPFBTG4?

A: Yes. Both substitute parts maintain identical electrical specifications, resolution, sampling rate, input configuration, supply voltage requirements, operating temperature range, and package dimensions. They are direct functional equivalents.

Q: What is the difference between ADS8371IPFBT and ADS8371IBPFBT?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in internal device binning or characterization. Both are Active products suitable for production use.

Q: Does the Tape & Reel packaging of the substitute parts affect circuit board compatibility?

A: No. Tape & Reel is a packaging and delivery format for automated assembly. The individual component in the 48-TQFP package is identical to the bulk-packaged original part. Board-level performance and pin configuration remain unchanged.

Q: Are the substitute parts ROHS3 compliant?

A: Yes. Both ADS8371IPFBT and ADS8371IBPFBT are ROHS3 compliant with MSL 2 (1 Year) ratings, matching the original part's compliance status.

Q: Why is the original ADS8371IPFBTG4 discontinued?

A: Product discontinuation is determined by the manufacturer. Active equivalent parts are available from Texas Instruments to support ongoing applications.
