Substitute Part Grouping Explanation

Substitute parts for the INA204AIPWR are selected based on strict parametric equivalence across the following criteria:

Electrical Specifications: All substitute parts maintain identical accuracy (±4.6%), input voltage range (-16V ~ 80V), output current (1mA), and operating temperature range (-40°C ~ 125°C).

Package Compatibility: All substitutes use the 14-TSSOP package form factor with identical 0.173" (4.40mm) width, ensuring direct PCB layout compatibility.

Sensing Architecture: All parts employ high-side current sensing methodology.

Compliance Standards: All substitutes maintain ROHS3 compliance, identical moisture sensitivity level (MSL 2, 1 Year), and equivalent regulatory classifications (ECCN EAR99).

Product Status Consideration: The main part (INA204AIPWR) is obsolete. Active substitute parts (INA203AIPWR, INA205AIPWR, INA206AIPWR, INA207AIPWR, INA208AIPWR) provide continued supply chain access. The INA203AQPWRQ1 variant adds automotive-grade qualification (AEC-Q100) for applications requiring automotive standards.

Engineering Selection Recommendations

For Standard Industrial Applications: INA205AIPWR and INA206AIPWR offer the highest inventory levels (13936 and 12100 units respectively) with active product status and full ROHS3 compliance. Both parts provide identical electrical and mechanical specifications to the obsolete INA204AIPWR.

For Automotive Applications: INA203AQPWRQ1 is the appropriate selection when AEC-Q100 automotive qualification is required. This part maintains all electrical parameters while adding automotive-grade certification and qualification status.

For General Replacement: INA203AIPWR provides the largest available inventory (11785 units) among non-automotive variants, ensuring supply chain continuity for high-volume production transitions.

Packaging Consideration: All substitute parts are supplied in Tape & Reel (TR) packaging except INA203AQPWRQ1, which is available in Cut Tape (CT) & Digi-Reel® format. Verify packaging requirements for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can INA204AIPWR be directly replaced with any of these substitute parts? A: Yes. All listed substitute parts maintain identical electrical specifications (±4.6% accuracy, -16V to 80V input range, 1mA output), operating temperature range (-40°C to 125°C), and 14-TSSOP package form factor. Direct PCB layout compatibility is assured.

Q: What is the difference between INA203AIPWR and INA203AQPWRQ1? A: Both parts share identical electrical and mechanical specifications. INA203AQPWRQ1 includes AEC-Q100 automotive qualification and is supplied in Cut Tape & Digi-Reel® packaging, while INA203AIPWR uses standard Tape & Reel packaging. Select INA203AQPWRQ1 for automotive applications requiring qualification documentation.

Q: Why are there multiple part numbers with identical specifications? A: The INA203, INA205, INA206, INA207, and INA208 series represent different product variants within the Texas Instruments current monitor family. Despite different base part numbers, these specific models share identical electrical performance and package specifications, making them parametric equivalents for the INA204AIPWR application.
