INA206AIDRG4 Equivalent & Substitute Parts

Part Overview

The INA206AIDRG4 is a high-side current monitor IC manufactured by Texas Instruments, designed for precision current measurement applications. This device operates across a wide input voltage range of -16V to 80V with ±4.6% accuracy and delivers a 1mA output signal. The INA206AIDRG4 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Active alternatives within the INA20x series provide direct functional replacement while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the INA206AIDRG4 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Function: Current Monitor
• Sensing Method: High-Side
• Accuracy: ±4.6%
• Voltage - Input Range: -16V ~ 80V
• Current - Output: 1mA
• Operating Temperature: -40°C ~ 125°C
• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2 (1 Year)

All substitute parts listed below meet these exact specifications. The primary distinction between the main part and substitutes is packaging format: the INA206AIDRG4 uses Dip packaging, while active substitutes are supplied in Tape & Reel (TR) format. Additionally, substitute parts carry Active product status, ensuring ongoing availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are direct functional equivalents to the INA206AIDRG4. Selection among these alternatives should be based on the following factors:

Product Status: The INA206AIDRG4 is obsolete. All substitute parts carry Active status, ensuring continued manufacturing support, availability, and compliance with current industry standards.

Compliance & Certifications: All substitute parts maintain ROHS3 compliance and identical MSL ratings, meeting the same environmental and regulatory requirements as the original part.

Packaging Consideration: The primary difference between the main part and substitutes is packaging format. The INA206AIDRG4 uses Dip packaging, while INA206AIDR, INA203AIDR, INA204AIDR, INA205AIDR, and INA208AIDR are supplied in Tape & Reel format. This distinction affects procurement and assembly processes but does not impact electrical performance or mechanical compatibility in 14-SOIC footprint applications.

Inventory Availability: INA206AIDR (4445 pcs), INA208AIDR (3920 pcs), INA205AIDR (3365 pcs), INA204AIDR (2100 pcs), and INA203AIDR (1514 pcs) are all in stock, providing multiple sourcing options.

Frequently Asked Questions (FAQ)

Q: Can INA206AIDR directly replace INA206AIDRG4 in existing designs?

A: Yes. INA206AIDR is the direct manufacturer-recommended substitute. Both parts share identical electrical specifications, accuracy ratings, voltage ranges, and 14-SOIC package dimensions. The only difference is packaging format (Tape & Reel vs. Dip), which does not affect circuit performance or PCB layout compatibility.

Q: What distinguishes the INA203AIDR, INA204AIDR, INA205AIDR, and INA208AIDR from INA206AIDR?

A: These parts are parametric equivalents within the INA20x current monitor family. All five substitute parts meet identical electrical and mechanical specifications for the INA206AIDRG4 application. The base product numbers (INA203, INA204, INA205, INA206, INA208) indicate different variants within the series, but for this substitution requirement, they are functionally interchangeable.

Q: Are there any thermal or environmental differences between substitute parts?

A: No. All substitute parts operate across the same temperature range (-40°C ~ 125°C) and carry identical MSL ratings of 2 (1 Year), ensuring equivalent performance in thermal and moisture-sensitive environments.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel is a supply format used for automated assembly processes. Once the component is removed from the reel and soldered to the PCB, electrical and mechanical performance is identical to Dip-packaged versions. The 14-SOIC footprint remains unchanged.

Q: Why is the INA206AIDRG4 listed as obsolete?

A: Product obsolescence indicates that Texas Instruments has discontinued manufacturing this specific part variant. Active substitutes within the INA20x series provide equivalent functionality and are recommended for new designs and production continuity.

Q: Can multiple substitute parts be used interchangeably within the same design?

A: Yes. All substitute parts meet identical specifications for the INA206AIDRG4 application. However, for production consistency and supply chain management, selecting a single primary substitute is recommended.
