Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS1625IPAPRG4 is determined by the following critical parameters: 18-bit resolution, 1.25M sampling rate, single differential input, parallel data interface, sigma-delta architecture, dual supply voltage configuration (5V analog / 2.7V–3.3V digital), and 64-PowerTQFP package. All identified substitutes maintain these electrical and mechanical specifications.

The primary distinction between substitute parts is packaging format and product status. The ADS1625IPAPT provides direct functional equivalence with Tape & Reel packaging and active product status. The ADS1626IPAPT represents a parametric equivalent, maintaining identical electrical specifications and package form factor while offering active availability.

Parameter Comparison

Engineering Selection Recommendations

The ADS1625IPAPT is the primary substitute for the obsolete ADS1625IPAPRG4. Both parts share identical base product designation and electrical specifications. The transition from tube packaging to Tape & Reel format aligns with standard manufacturing practices for active production components. Active product status ensures continued availability and supply chain reliability.

The ADS1626IPAPT provides an alternative path for applications requiring active component sourcing. While designated as a parametric equivalent with a different base product number, it maintains all critical electrical parameters and package specifications. Selection between ADS1625IPAPT and ADS1626IPAPT depends on supply chain requirements and inventory management strategies, as both satisfy the functional and compliance requirements of the original design.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical MSL ratings, ensuring compatibility with existing manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can ADS1625IPAPT directly replace ADS1625IPAPRG4 in production?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, resolution, sampling rate, input configuration, supply voltages, operating temperature range, and 64-PowerTQFP package. The difference is packaging format: ADS1625IPAPRG4 uses tube packaging while ADS1625IPAPT uses Tape & Reel format. ADS1625IPAPT is the active equivalent.

Q: What is the difference between ADS1625IPAPT and ADS1626IPAPT?

A: Both parts maintain identical electrical parameters and package specifications. The distinction is the base product number: ADS1625 versus ADS1626. Both are active products from Texas Instruments and satisfy all functional requirements of the original design.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 3 (168 Hours). Compliance certifications are equivalent across all variants.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel packaging is a distribution format only. The die, electrical characteristics, and performance specifications remain identical to tube-packaged versions. Tape & Reel format is standard for active production components and offers advantages in automated assembly processes.

Q: What supply voltage requirements must be maintained for substitution?

A: All substitute parts require 5V analog supply and 2.7V to 3.3V digital supply, matching the original ADS1625IPAPRG4 specifications. No supply circuit modifications are necessary.

Q: Are the pin configurations identical across all three parts?

A: Yes. All parts use the 64-PowerTQFP (10x10) package with identical pinout. Direct PCB compatibility is maintained without layout modifications.
