INA286AIDR Equivalent & Substitute Parts

Part Overview

The INA286AIDR is a Zero-Drift current monitor IC manufactured by Texas Instruments, designed for high/low-side current sensing applications. This device operates across a wide input voltage range of -14V to 80V with ±0.4% accuracy and is housed in an 8-SOIC surface mount package. The part is currently active in production status and fully compliant with RoHS3 and REACH regulations.

Substitute parts are necessary when the primary part experiences supply constraints, when specific packaging or qualification requirements must be met (such as automotive-grade AEC-Q100 certification), or when alternative inventory sources are required to maintain production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the INA286AIDR is determined by strict equivalence across the following critical parameters:

• Sensing Method: All substitutes must provide High/Low-Side current sensing capability
• Accuracy: All substitutes must maintain ±0.4% accuracy specification
• Input Voltage Range: All substitutes must support -14V ~ 80V operation
• Operating Temperature Range: All substitutes must cover -40°C ~ 125°C
• Package / Case: All substitutes must use 8-SOIC (0.154", 3.90mm Width) form factor
• Mounting Type: All substitutes must be Surface Mount compatible
• Compliance: All substitutes must maintain RoHS3 and REACH compliance status

The substitute parts listed below are organized by base product number (INA282, INA283, INA284, INA285, INA286) and packaging variant (Tape & Reel, Cut Tape & Digi-Reel®). Automotive-grade variants with AEC-Q100 qualification are identified separately to support applications requiring automotive compliance.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full parametric equivalence with the INA286AIDR across sensing method, accuracy, voltage range, temperature range, and package specifications. Selection between substitutes should be based on the following criteria:

For Standard Industrial Applications: INA284AIDR, INA285AIDR, and INA283AIDR are direct functional equivalents with standard-grade qualification. These parts are suitable for non-automotive applications where AEC-Q100 certification is not required.

For Automotive Applications: INA282AQDRQ1, INA283AQDRQ1, INA284AQDRQ1, INA285AQDRQ1, and INA286AQDRQ1 carry automotive-grade designation with AEC-Q100 qualification. These variants are required for automotive-grade system designs and applications subject to automotive reliability standards.

For Packaging Considerations: Tape & Reel (TR) packaging is suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides flexibility for lower-volume or mixed-component pick-and-place operations. The INA286AIDR uses Tape & Reel packaging; equivalent Tape & Reel variants include INA283AQDRQ1, INA284AIDR, INA284AQDRQ1, INA285AIDR, and INA285AQDRQ1.

For Inventory Availability: INA282AQDRQ1 offers the highest current inventory level (21,290 pcs), followed by INA285AQDRQ1 (17,672 pcs), making these options preferable for immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can I substitute INA286AIDR with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts maintain identical specifications for sensing method (High/Low-Side), accuracy (±0.4%), input voltage range (-14V ~ 80V), operating temperature (-40°C ~ 125°C), and 8-SOIC package form factor. No circuit redesign is required for parametric substitution.

Q: What is the difference between standard-grade and automotive-grade variants?

A: Automotive-grade variants (identified by "AQDRQ1" suffix) carry AEC-Q100 qualification and are designed to meet automotive reliability and qualification standards. Standard-grade variants (identified by "AIDR" suffix) are suitable for industrial and consumer applications. Automotive applications must use AEC-Q100 qualified parts.

Q: Does packaging type affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging variants contain identical die and electrical specifications. Packaging selection is determined by assembly process requirements and volume considerations, not electrical performance.

Q: Are all substitute parts RoHS3 and REACH compliant?

A: Yes. All listed substitute parts maintain RoHS3 Compliant and REACH Unaffected status, matching the compliance profile of the INA286AIDR.

Q: Which substitute part should I select if the primary part is unavailable?

A: Selection depends on application requirements. For automotive applications, select from AEC-Q100 qualified variants (INA282AQDRQ1, INA283AQDRQ1, INA284AQDRQ1, INA285AQDRQ1, INA286AQDRQ1). For standard industrial applications, any listed part is suitable. Consider inventory availability and packaging requirements for your assembly process.

Q: Is the Moisture Sensitivity Level (MSL) identical across all parts?

A: Yes. All parts carry MSL 2 (1 Year) rating, indicating identical moisture handling and storage requirements.
