ADS7864Y/2K Equivalent & Substitute Parts

Part Overview

The ADS7864Y/2K is a 12-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for multi-channel data acquisition applications. This SAR (Successive Approximation Register) architecture device features 6 differential inputs with dual simultaneous sampling capability and SPI digital interface. The part is currently in active production status with full RoHS3 compliance and REACH unaffected designation. Alternative packaging configurations of this device may be required due to supply chain availability, procurement lead times, or specific assembly requirements in manufacturing environments.

Substitute Part Grouping Explanation

The ADS7864Y/250 qualifies as a parametric equivalent to the ADS7864Y/2K based on identical electrical and functional specifications. Both devices share the same core architecture, resolution, sampling rate, input configuration, and supply voltage requirements. The distinction between these part numbers relates exclusively to packaging format: the ADS7864Y/2K is supplied in Tape & Reel (TR) format, while the ADS7864Y/250 is supplied in Cut Tape (CT) and Digi-Reel® format. This packaging difference does not affect electrical performance, pin configuration, or functional capability. Substitution is valid when the receiving application can accommodate the alternative packaging format during assembly and procurement workflows.

Parameter Comparison

Engineering Selection Recommendations

Both the ADS7864Y/2K and ADS7864Y/250 maintain active product status with identical compliance certifications. Selection between these parts should be determined by assembly line requirements and procurement specifications. The Tape & Reel format (ADS7864Y/2K) is optimized for high-volume automated pick-and-place assembly operations. The Cut Tape and Digi-Reel® format (ADS7864Y/250) accommodates lower-volume production runs, manual assembly processes, or applications requiring component-level flexibility. Both variants carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across manufacturing environments. No functional or electrical performance differences exist between these part numbers.

Frequently Asked Questions (FAQ)

Q: Are the ADS7864Y/2K and ADS7864Y/250 electrically identical?

A: Yes. Both parts are manufactured to identical electrical specifications, including 12-bit resolution, 500k samples per second sampling rate, 6 differential inputs, dual SAR converters, and 5V supply requirements. No functional differences exist.

Q: What is the only difference between these part numbers?

A: The packaging format. ADS7864Y/2K is supplied in Tape & Reel (TR) format for automated assembly. ADS7864Y/250 is supplied in Cut Tape (CT) and Digi-Reel® format for manual or lower-volume assembly.

Q: Can I substitute ADS7864Y/250 for ADS7864Y/2K in my design?

A: Yes, provided your assembly process can accommodate Cut Tape and Digi-Reel® packaging. The 48-TQFP (7x7) package footprint and pin configuration are identical, requiring no PCB design changes.

Q: Do both parts have the same compliance certifications?

A: Yes. Both ADS7864Y/2K and ADS7864Y/250 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Which packaging format should I specify for high-volume production?

A: Tape & Reel (TR) format, represented by ADS7864Y/2K, is standard for high-volume automated assembly operations due to compatibility with pick-and-place equipment.

Q: Are there any performance differences between Tape & Reel and Cut Tape packaging?

A: No. Packaging format affects only supply chain logistics and assembly methodology. Electrical performance, reliability, and functional specifications are identical.
