Equivalent & Substitute Parts Reference: INA186A3IDDFT

Part Overview

The INA186A3IDDFT from Texas Instruments is a linear amplifier classified as a current sense amplifier with a single circuit and rail-to-rail output in a TSOT-23-8 package. It belongs to the Zero-Drift series and offers low input bias current, minimal input offset voltage, and low supply current for precise current sensing. The product status is "Last Time Buy," indicating it will be phased out. Identifying precise substitute or alternative part numbers within the same electrical and mechanical parameter set is essential for continued design availability and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for current sense amplifiers in the Zero-Drift series is based strictly on identical values of the following allowed parameters: amplifier type, number of circuits, output type, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, supply voltage range, operating temperature range, mounting type, package/case, RoHS and REACH compliance, ECCN, and series. Mechanical packaging and supplier device package must also match for form and fit compatibility.

Engineering Selection Recommendations

For engineering substitution of INA186A3IDDFT in the current sense amplifier category, select INA186A3IDDFR based on identical electrical and mechanical parameters, packaging, and compliance statuses including RoHS3 and REACH. This substitute maintains alignment with ECCN and HTSUS classifications. The main differentiator is product lifecycle status; INA186A3IDDFT is "Last Time Buy," whereas INA186A3IDDFR is "Active." This ensures ongoing availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: What determines a valid substitute for the INA186A3IDDFT current sense amplifier?
A: Substitution requires identical electrical parameters, mechanical package (TSOT-23-8), mounting type, compliance statuses, and documentation alignment.

Q: Is the INA186A3IDDFR compatible in the same footprint as INA186A3IDDFT?
A: Yes. Both use the SOT-23-8 case and TSOT-23-8 supplier device package with surface mount type.

Q: Are there differences in environmental or compliance standards between INA186A3IDDFT and INA186A3IDDFR?
A: No. Both parts are ROHS3 compliant, REACH unaffected, MSL 1 (unlimited), ECCN EAR99, and HTSUS 8542.33.0001.

Q: Which inventory status should be prioritized for ongoing designs?
A: Select the substitute part with "Active" product status to ensure long-term supply continuity.

Q: Do these substitute parts differ in electrical or performance characteristics?
A: No. All key electrical performance parameters are identical as specified in the comparison table.
