ADS8342IPFBR Equivalent & Substitute Parts Reference

Part Overview

The ADS8342IPFBR from Texas Instruments is a 16 Bit Analog to Digital Converter (ADC) featuring a successive approximation register (SAR) architecture, four inputs, parallel data interface, selectable address feature, and a 48-TQFP surface mount package. This product is currently classified as "Obsolete." When a part becomes obsolete, it is critical to identify equivalent substitute models that match all required electrical and mechanical parameters for direct replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on key parameters necessary for electrical and mechanical interchangeability in data acquisition ADC designs. Electrical characteristics include resolution (number of bits), sampling rate, number of inputs, input type, data interface, configuration, S/H-ADC ratio, reference type, supply voltages, features, architecture, operating temperature range, mounting type, package, and compliance (RoHS, REACH, MSL). Only substitute parts matching these parameters are suitable for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

For designs utilizing ADS8342IPFBR, engineering substitution should be based on product status and compliance information. ADS8342IPFBR is listed as Obsolete, while the parametric equivalent ADS8342IBPFBT is available as "Last Time Buy." Both devices maintain the identical electrical, mechanical, and compliance characteristics required for interchangeability, including RoHS3 compliance and REACH unaffected status. Moisture Sensitivity Level (MSL) matches, and both products are surface mountable in a 48-TQFP (7x7) package.

Frequently Asked Questions (FAQ)

Q1: What are the critical criteria for substituting the ADS8342IPFBR in a design?
A1: Critical criteria include matching the number of bits, sampling rate, input configuration, data interface, supply voltages, S/H-ADC configuration, operating temperature range, package type (48-TQFP), mounting style, and compliance certifications (RoHS3, REACH, MSL).

Q2: Is the package identical between ADS8342IPFBR and ADS8342IBPFBT?
A2: Yes, both components use the 48-TQFP (7x7) package and are designed for surface mounting.

Q3: What compliance certifications are maintained in substitute selection?
A3: Both the main and substitute parts have RoHS3 compliant and REACH unaffected status, as well as the same MSL 2 (1 Year).

Q4: How does product status affect component selection?
A4: Product status determines availability; the main part is Obsolete while the substitute is "Last Time Buy," ensuring continuity in sourcing while maintaining strict compatibility.
