ADS1174IPAPR Equivalent & Substitute Parts

Part Overview

The ADS1174IPAPR is a 16-bit Sigma-Delta analog-to-digital converter manufactured by Texas Instruments, designed for multi-channel data acquisition applications. This device features 4 differential or single-ended inputs with simultaneous sampling capability and SPI digital interface. The part is currently in active production status with full RoHS3 compliance and REACH unaffected designation.

Substitute parts are identified when packaging or supply chain requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications. The ADS1174IPAPR is supplied in Tape & Reel (TR) packaging; alternative packaging formats of the same base device may be required for specific procurement or assembly workflows.

Substitute Part Grouping Explanation

Substitution of the ADS1174IPAPR is based on strict equivalence of the following critical parameters:

  • 16-bit resolution and 52k sampling rate
  • 4-channel input configuration with differential and single-ended capability
  • SPI digital interface protocol
  • Sigma-Delta architecture
  • 5V analog supply and 1.65V ~ 1.95V digital supply requirements
  • 64-PowerTQFP (10x10) package footprint and Surface Mount mounting type
  • Identical RoHS3 compliance and MSL 3 rating

The ADS1174IPAPT is a parametric equivalent that differs only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Both parts share the same base product number (ADS1174) and are manufactured by Texas Instruments with identical electrical specifications and performance characteristics.

Engineering Selection Recommendations

Both the ADS1174IPAPR and ADS1174IPAPT are active production devices with full RoHS3 compliance and REACH unaffected status. Selection between these parts is determined by packaging and supply chain requirements rather than electrical performance.

The ADS1174IPAPR in Tape & Reel format is suitable for high-volume automated assembly operations. The ADS1174IPAPT in Cut Tape & Digi-Reel® format accommodates lower-volume production runs, prototype development, or applications requiring flexible component sourcing.

Both parts maintain identical electrical specifications, thermal performance, and compliance certifications. PCB layout, schematic design, and firmware implementation remain unchanged between these variants.

Frequently Asked Questions (FAQ)

Q: Can ADS1174IPAPT be used as a direct replacement for ADS1174IPAPR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, pin configuration, and performance characteristics. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®).

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape & Digi-Reel® provides components on cut tape segments or alternative reel formats, suitable for lower-volume assembly or manual handling.

Q: Are there any PCB layout or schematic changes required when switching between these parts?

A: No. Both parts use the identical 64-PowerTQFP (10x10) package footprint and pin assignment. No design modifications are necessary.

Q: Do both parts have the same moisture sensitivity and storage requirements?

A: Yes. Both parts carry MSL 3 rating with 168-hour floor life. Storage and handling procedures are identical.

Q: Which part should be selected for production?

A: Selection depends on assembly volume and supply chain strategy. High-volume production typically uses ADS1174IPAPR (Tape & Reel). Lower-volume or flexible sourcing scenarios use ADS1174IPAPT (Cut Tape & Digi-Reel®).
