ADS8321EB/2K5 Equivalent & Substitute Parts

Part Overview

The ADS8321EB/2K5 is a 16-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, classified as a microPOWER™ series data acquisition component. This SAR (Successive Approximation Register) architecture device features a single differential, pseudo-differential, or single-ended input with SPI data interface and external reference capability. The part is currently in Active product status with 2352 units in stock. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative part numbers that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the ADS8321EB/2K5 are identified based on parametric equivalence within the ADS8321 base product family. Substitution is valid when all of the following criteria are met:

• Identical number of bits (16-bit resolution)
• Identical sampling rate (100k samples per second)
• Identical number of inputs (1 input channel)
• Identical input type support (Differential, Pseudo-Differential, Single Ended)
• Identical data interface (SPI)
• Identical architecture (SAR)
• Identical reference type (External)
• Identical supply voltages (5V analog and digital)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical package type (8-VSSOP)
• Identical mounting type (Surface Mount)
• Identical compliance certifications (ROHS3, REACH Unaffected, EAR99)

The substitute parts ADS8321E/250 and ADS8321EB/250 meet all these criteria and are therefore direct parametric equivalents suitable for interchangeable use in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—ADS8321EB/2K5, ADS8321E/250, and ADS8321EB/250—are Active status products manufactured by Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability and procurement lead times
• Packaging format requirements (Cut Tape or Digi-Reel®)
• Supply chain logistics and cost considerations

All parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 classification, making them suitable for equivalent use in regulated applications. The 8-VSSOP package and Surface Mount mounting type are consistent across all variants, ensuring PCB layout and assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can ADS8321E/250 be used as a direct replacement for ADS8321EB/2K5?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, pin configuration, package type, and compliance certifications. They are interchangeable at the circuit design and PCB assembly level.

Q: What is the difference between ADS8321EB/2K5 and ADS8321EB/250?

A: The difference lies in packaging format and quantity per reel. The "/2K5" designation indicates 2500-unit Digi-Reel® packaging, while "/250" indicates 250-unit Cut Tape packaging. Electrical and mechanical specifications are identical.

Q: Are there any temperature or voltage derating considerations when substituting these parts?

A: No. All three parts operate identically across the -40°C to 85°C temperature range with 5V analog and digital supply voltages. No derating or circuit modification is required.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts carry MSL 2 (1 Year) classification, requiring identical storage and handling conditions.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Yes, provided the application requirements are met by the specified electrical parameters. All parts maintain ROHS3 compliance and REACH Unaffected status. Compliance with application-specific standards should be verified independently.
