INA282AIDR Equivalent & Substitute Parts

Part Overview

The INA282AIDR is an active current monitor integrated circuit manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This Zero-Drift current monitor operates across a wide input voltage range of -14V to 80V and delivers ±0.4% measurement accuracy for high/low-side current sensing applications. The device is housed in an 8-SOIC surface mount package and maintains Active product status with full ROHS3 compliance and AEC-Q100 qualification availability through automotive-grade variants.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when specific packaging or qualification requirements change, or when design flexibility allows for alternative sensing configurations within the same electrical and mechanical parameter space.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the INA282AIDR is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Manufacturer: Texas Instruments
• Function: Current Monitor
• Sensing Method: High/Low-Side
• Accuracy: ±0.4%
• Voltage - Input Range: -14V ~ 80V
• Operating Temperature: -40°C ~ 125°C
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2 (1 Year)

All substitute parts listed maintain identical electrical specifications and mechanical compatibility. Variations exist only in base product number (INA282, INA283, INA284, INA285, INA286), packaging format (Cut Tape vs. Tape & Reel), and automotive qualification status (standard vs. AEC-Q100 qualified variants).

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: INA282AIDR, INA283AIDR, INA284AIDR, INA285AIDR, and INA286AIDR are direct equivalents suitable for non-automotive applications. Selection among these variants depends on packaging format preference and inventory availability. Cut Tape (CT) & Digi-Reel® packaging is appropriate for lower-volume or manual assembly processes, while Tape & Reel (TR) packaging supports automated pick-and-place assembly.

For Automotive Applications: INA282AQDRQ1, INA283AQDRQ1, INA284AQDRQ1, INA285AQDRQ1, and INA286AQDRQ1 are AEC-Q100 qualified variants required for automotive-grade designs. These parts maintain identical electrical and mechanical specifications while meeting automotive reliability and qualification standards.

Packaging Format Considerations: The INA282AIDR is supplied in Cut Tape (CT) & Digi-Reel® format. Equivalent parts in Tape & Reel (TR) format (INA283AQDRQ1, INA284AIDR, INA284AQDRQ1, INA285AIDR, INA285AQDRQ1, INA286AIDR, INA286AQDRQ1) are mechanically and electrically compatible but require compatible reel handling equipment for assembly operations.

Inventory and Availability: INA285AQDRQ1 maintains the highest inventory level (17,672 pcs), followed by INA282AIDR (21,388 pcs) and INA282AQDRQ1 (21,290 pcs), providing optimal availability for high-volume procurement.

Frequently Asked Questions (FAQ)

Q: Can I substitute INA282AIDR with any of the listed equivalent parts? A: Yes. All listed parts maintain identical electrical specifications (±0.4% accuracy, -14V to 80V input range, -40°C to 125°C operating temperature) and mechanical compatibility (8-SOIC package, surface mount). Substitution is valid across all variants provided the application does not require automotive AEC-Q100 qualification.

Q: What is the difference between standard and automotive-grade variants? A: Standard variants (AIDR suffix) are suitable for industrial and consumer applications. Automotive-grade variants (AQDRQ1 suffix) carry AEC-Q100 qualification, meeting automotive reliability, testing, and qualification requirements. Electrical and mechanical specifications are identical.

Q: Does packaging format affect electrical performance? A: No. Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) formats contain identical die and electrical characteristics. Packaging format selection depends on assembly equipment compatibility and volume requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts maintain ROHS3 compliance and identical Moisture Sensitivity Level 2 (1 Year) rating.

Q: Can I use INA286AQDRQ1 as a direct replacement for INA282AIDR? A: Yes. INA286AQDRQ1 is electrically and mechanically equivalent. The primary difference is automotive AEC-Q100 qualification. If your application does not require automotive certification, standard-grade variants provide equivalent performance at potentially lower cost.

Q: What determines which base product number (INA282, INA283, INA284, INA285, INA286) to select? A: All base product numbers within this family maintain identical electrical specifications and mechanical compatibility. Selection is determined by packaging format availability, inventory levels, and automotive qualification requirements rather than functional differences.
