ADS1601IPFBR Equivalent & Substitute Parts
Part Overview
The ADS1601IPFBR is a 16-bit analog-to-digital converter manufactured by Texas Instruments, designed for single-channel differential input applications. This sigma-delta architecture ADC operates with an external or internal reference and communicates via SPI interface. The device is actively produced and ROHS3 compliant, making it suitable for industrial and commercial data acquisition systems requiring high-resolution analog signal conversion.
Substitute parts are identified when design flexibility is needed due to inventory constraints, packaging preferences, or supply chain considerations while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation
The ADS1601IPFBT qualifies as a parametric equivalent to the ADS1601IPFBR based on identical electrical and mechanical specifications. Both devices share the same base product number (ADS1601), resolution, sampling rate, input configuration, interface protocol, supply voltage requirements, temperature range, and package footprint.
The primary distinction between these parts is packaging format: the ADS1601IPFBR is supplied in standard packaging, while the ADS1601IPFBT is supplied in Tape & Reel (TR) format. This difference affects only procurement and assembly logistics, not functional performance or circuit compatibility.
Substitution is valid when the following parameters remain constant:
- 16-bit resolution
- 1.25 MSPS sampling rate
- Single differential input
- SPI communication protocol
- 48-TQFP package footprint
- Sigma-delta architecture
- Dual supply voltage configuration (5V analog, 2.7V–3.3V digital)
- Operating temperature range (-40°C to 85°C)

Engineering Selection Recommendations
Both the ADS1601IPFBR and ADS1601IPFBT are active products from Texas Instruments with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement requirements and assembly processes.
The ADS1601IPFBR in standard packaging is suitable for low-volume applications, prototyping, and situations requiring individual component handling. The ADS1601IPFBT in Tape & Reel format is optimized for high-volume production runs and automated pick-and-place assembly operations, offering cost efficiency and reduced handling time.
Both devices maintain identical electrical performance, thermal characteristics, and circuit compatibility. PCB layout, schematic design, and firmware implementation require no modification when substituting between these variants.
Frequently Asked Questions (FAQ)
Q: Can ADS1601IPFBT replace ADS1601IPFBR in production designs?
A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (standard versus Tape & Reel). No circuit modifications are required.
Q: What is the difference between standard packaging and Tape & Reel format?
A: Standard packaging supplies individual components suitable for manual handling and low-volume assembly. Tape & Reel format supplies components on continuous tape for automated assembly equipment. Electrical performance is identical.
Q: Are there any compatibility issues when switching between these parts?
A: No. Both parts use the same 48-TQFP (7x7) footprint, pin configuration, and electrical specifications. PCB design and firmware remain unchanged.
Q: Which part should be selected for high-volume manufacturing?
A: The ADS1601IPFBT (Tape & Reel format) is recommended for high-volume production due to compatibility with automated assembly processes and improved supply chain efficiency.
Q: Do both parts meet the same compliance standards?
A: Yes. Both the ADS1601IPFBR and ADS1601IPFBT are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 2 (1 Year).
Q: What is the operating temperature range for both parts?
A: Both parts operate across -40°C to 85°C, suitable for industrial and commercial applications.
Q: Are the supply voltage requirements identical?
A: Yes. Both parts require 5V analog supply and 2.7V to 3.3V digital supply with identical electrical characteristics.
