ADS1626IPAPR Equivalent & Substitute Parts

Part Overview

The ADS1626IPAPR is an 18-bit analog-to-digital converter manufactured by Texas Instruments, designed for single-channel differential input applications with sigma-delta architecture. This component operates with external or internal voltage references and supports parallel data interface output. The ADS1626IPAPR is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Engineering Selection Recommendations

ADS1626IPAPT is the primary direct substitute for ADS1626IPAPR. Both parts share identical part number base (ADS1626) and electrical specifications. The distinction lies in packaging format: ADS1626IPAPT is supplied in Tape & Reel (TR) format, whereas ADS1626IPAPR packaging format is not specified. ADS1626IPAPT maintains active product status with Texas Instruments, ensuring ongoing availability and support.

ADS1625IPAPT serves as a parametric equivalent substitute. This part maintains all critical electrical parameters—18-bit resolution, 1.25M sampling rate, differential input, sigma-delta architecture, and identical supply voltage requirements—while representing a different base product number (ADS1625). ADS1625IPAPT is also supplied in Tape & Reel format and maintains active product status.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Selection between ADS1626IPAPT and ADS1625IPAPT depends on design documentation requirements and existing part number specifications in production systems.

Frequently Asked Questions (FAQ)

Q: Can ADS1626IPAPT directly replace ADS1626IPAPR in existing designs?

A: Yes. ADS1626IPAPT is a direct substitute with identical electrical specifications, pin configuration, and 64-PowerTQFP package. The primary difference is packaging format (Tape & Reel versus unspecified format for the original part).

Q: What is the difference between ADS1626IPAPT and ADS1625IPAPT?

A: Both parts are parametric equivalents with identical electrical performance: 18-bit resolution, 1.25M sampling rate, differential input, and sigma-delta architecture. The difference is the base product number (ADS1626 versus ADS1625). Both are suitable for applications requiring these specifications.

Q: Are all substitute parts surface mount compatible?

A: Yes. All listed parts use 64-PowerTQFP (10x10) surface mount packaging, maintaining identical PCB footprint and reflow soldering requirements.

Q: Do substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original ADS1626IPAPR.

Q: Why is ADS1626IPAPR marked as obsolete?

A: ADS1626IPAPR is classified as obsolete by Texas Instruments. Active alternatives (ADS1626IPAPT and ADS1625IPAPT) are available to support ongoing production requirements.

Q: What is the moisture sensitivity level, and does it affect handling?

A: All parts have Moisture Sensitivity Level 3 (168 Hours), requiring standard moisture control during storage and handling per IPC standards.
