INA223AIDSKR Equivalent & Substitute Parts

Part Overview

The INA223AIDSKR is a current and voltage monitor IC from Texas Instruments, designed for high/low-side sensing applications. This device operates across a 0V to 26V input range and is housed in a 10-SON (2.5x2.5) package with exposed pad. The INA223AIDSKR is currently in active production status with 3200 units available in stock. Given its active status and specific packaging configuration, identifying equivalent substitute parts ensures design flexibility and supply chain continuity for applications requiring current and voltage monitoring functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the INA223AIDSKR is determined by strict alignment of the following parameters:

• Base product number (INA223)
• Function (Current/Voltage Monitor)
• Sensing method (High/Low-Side)
• Input voltage range (0V ~ 26V)
• Operating temperature range (-40°C ~ 105°C)
• Package type (10-WFDFN Exposed Pad / 10-SON 2.5x2.5)
• Mounting type (Surface Mount)
• Series classification (Zero-Drift)
• Compliance certifications (ROHS3, REACH Unaffected)

The INA223AIDSKT qualifies as a parametric equivalent based on these criteria. The primary distinction between these parts is the packaging format: the INA223AIDSKR is supplied in tube packaging, while the INA223AIDSKT is supplied in tape and reel format.

Parameter Comparison

Engineering Selection Recommendations

The INA223AIDSKR is the primary selection for new designs due to its active product status. The INA223AIDSKT is functionally equivalent and maintains identical electrical and mechanical specifications, making it suitable for applications where tape and reel packaging is preferred or required for automated assembly processes.

Selection between these parts should be based on packaging requirements and supply availability. The INA223AIDSKR offers continued production support, while the INA223AIDSKT is designated as Last Time Buy, indicating limited future availability. Both parts meet ROHS3 compliance and REACH requirements, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can INA223AIDSKT be used as a direct replacement for INA223AIDSKR?

A: Yes. Both parts share identical electrical specifications, operating parameters, and physical package dimensions. The only difference is the packaging format: tube versus tape and reel. Functional performance and PCB footprint compatibility are equivalent.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging (INA223AIDSKR) is suitable for manual assembly and lower-volume applications. Tape and reel packaging (INA223AIDSKT) is designed for automated pick-and-place assembly systems and higher-volume production runs. The components themselves are identical.

Q: Why is INA223AIDSKT marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments will discontinue production of this specific packaging variant. Existing inventory remains available, but future orders may not be possible. The INA223AIDSKR (Active status) is recommended for long-term design commitments.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts operate across the same temperature range (-40°C to 105°C) and share identical moisture sensitivity levels (MSL 1). Thermal and reliability characteristics are equivalent.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the assembly process can accommodate the packaging format. If your production line uses automated tape and reel feeding, the INA223AIDSKT is suitable. If manual assembly or tube-based handling is used, the INA223AIDSKR is appropriate. Electrical and mechanical compatibility is complete.
