INA186A5IDDFT Equivalent & Substitute Parts Reference Guide

Part Overview

The Texas Instruments INA186A5IDDFT is a current sense amplifier categorized under Linear, Amplifiers, with rail-to-rail output, optimized for precision measurement applications. It is offered in a TSOT-23-8 surface-mount package and operates over a supply voltage span of 1.7 V to 5.5 V. This part is classified as "Last Time Buy," indicating that procurement is limited to end-of-life supply, making it necessary to identify alternatives for future designs or ongoing production requirements.

Substitute Part Grouping Explanation

Substitute parts are identified strictly by the following parameters: manufacturer, amplifier type, number of circuits, output type, slew rate, gain bandwidth product, current input bias, voltage input offset, current supply, voltage supply span (min/max), operating temperature range, package/case, mounting type, RoHS compliance, Moisture Sensitivity Level, and REACH status. All substitute parts must have values matching these key characteristics to ensure form, fit, and functional compatibility within the Linear, Amplifiers category.

Engineering Selection Recommendations

INA186A5IDDFT is designated as "Last Time Buy," meaning future availability is limited. INA186A5IDDFR is listed as "Active," meeting all provided compliance standards (ROHS3 Compliant, Moisture Sensitivity Level 1, REACH Unaffected). Both parts have identical key parameters and certifications. For ongoing or new projects, selection may be based on product status and existing compliance documentation.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting INA186A5IDDFT in a design?
A1: Substitute parts must match manufacturer, amplifier type, number of circuits, output type, slew rate, gain bandwidth product, current input bias, voltage input offset, current supply, voltage supply span, operating temperature, package/case, mounting type, RoHS status, Moisture Sensitivity Level, and REACH status.

Q2: Is the package of INA186A5IDDFR identical to INA186A5IDDFT for PCB compatibility?
A2: Both INA186A5IDDFR and INA186A5IDDFT use the TSOT-23-8 supplier device package and SOT-23-8 case, supporting direct footprint compatibility in surface-mount designs.

Q3: Are there any differences in environmental or compliance certifications between the main part and its substitute?
A3: Both part numbers are ROHS3 Compliant, have Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status.

Q4: What does "Last Time Buy" status imply for INA186A5IDDFT?
A4: "Last Time Buy" status indicates limited procurement opportunity and that manufacturers recommend selecting an active alternative for ongoing supply continuity.

Q5: Can INA186A5IDDFR be directly used as a drop-in replacement for INA186A5IDDFT?
A5: Based strictly on provided parameters, INA186A5IDDFR meets all equivalence requirements for direct replacement within the Linear, Amplifiers component category.
