ADS7816UB/2K5 Equivalent & Substitute Parts

Part Overview

The ADS7816UB/2K5 is a 12-bit Analog to Digital Converter manufactured by Texas Instruments, configured as a single-input SAR (Successive Approximation Register) architecture device in 8-SOIC surface mount packaging. This data acquisition component operates with external voltage references and communicates via SPI interface, supporting differential input measurement at 200k samples per second. The part is currently in active production status with ROHS3 compliance and MSL 2 moisture sensitivity rating.

Substitute parts are necessary when the primary part becomes unavailable due to supply constraints, manufacturing discontinuation, or when alternative packaging formats are required for specific assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS7816UB/2K5 is determined by strict equivalence across the following critical parameters: 12-bit resolution, 200k samples per second sampling rate, single differential input, SPI data interface, SAR architecture, external reference configuration, 5V analog and digital supply voltages, -40°C to 85°C operating temperature range, and 8-SOIC surface mount package.

Texas Instruments ADS7816 series variants (ADS7816U/2K5, ADS7816UC/2K5, ADS7817UC/2K5) maintain full parametric equivalence across all electrical and mechanical specifications. These parts differ only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and inventory availability, making them direct functional substitutes.

Renesas Electronics ISL series parts (ISL2671286IBZ, ISL267817IBZ-T7A) share identical electrical specifications and package geometry but carry obsolete product status. ISL2671286IBZ operates at reduced sampling rate (20k samples per second), creating a functional limitation that restricts its use to applications not requiring full 200k sample rate performance.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring full parametric equivalence with active product support, select from the Texas Instruments ADS7816 series variants: ADS7816U/2K5, ADS7816UC/2K5, or ADS7817UC/2K5. All three maintain identical electrical performance and 8-SOIC package compatibility. Selection between these parts should be based on packaging format requirements (Tape & Reel versus Cut Tape & Digi-Reel) and inventory availability. ADS7816U/2K5 offers the highest current stock (2011 units) and Cut Tape packaging suitable for automated pick-and-place assembly. ADS7817UC/2K5 provides maximum inventory depth (3693 units) in Tape & Reel format.

Renesas Electronics ISL series parts carry obsolete product status and should be considered only for legacy system maintenance or when new production is not feasible. ISL2671286IBZ operates at 20k samples per second, creating a 10:1 reduction in sampling rate that restricts use to low-frequency measurement applications. ISL267817IBZ-T7A maintains full 200k sample rate performance but remains discontinued.

All substitute candidates maintain ROHS3 compliance, identical operating temperature range (-40°C to 85°C), and compatible moisture sensitivity ratings (MSL 1 or 2), ensuring compliance with standard industrial and commercial assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ADS7816U/2K5 replace ADS7816UB/2K5 in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical specifications and package geometry. The difference is packaging format: ADS7816UB/2K5 uses Tape & Reel while ADS7816U/2K5 uses Cut Tape & Digi-Reel. Functional performance is identical.

Q: What is the key difference between ADS7817UC/2K5 and ADS7816UC/2K5?

A: Both parts share identical electrical specifications, sampling rate, resolution, and package type. The base product number differs (ADS7817 versus ADS7816), but this does not affect functional compatibility in applications designed for 12-bit, 200k sample/second SAR ADC operation.

Q: Why does ISL2671286IBZ have lower sampling rate?

A: ISL2671286IBZ operates at 20k samples per second versus 200k samples per second for the primary part. This 10:1 reduction in sampling rate limits its use to applications with lower bandwidth requirements. It is not suitable for designs requiring full 200k sample rate performance.

Q: Are Renesas ISL parts suitable for new designs?

A: No. Both ISL2671286IBZ and ISL267817IBZ-T7A carry obsolete product status. They should be used only for legacy system maintenance or repair. New designs should use active Texas Instruments ADS7816 series parts.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel, Cut Tape & Digi-Reel, and Tube packaging formats do not affect electrical performance. Selection should be based on assembly process requirements and inventory availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and are suitable for applications requiring RoHS certification.
