INA209AIPWG4 Equivalent & Substitute Parts

Part Overview

The INA209AIPWG4 is a high-side current monitor IC manufactured by Texas Instruments, designed for power management applications requiring precise current measurement. This device operates across an input voltage range of 0V to 26V with ±1% accuracy and is housed in a 16-TSSOP surface mount package. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the INA209AIPWG4 is determined by strict equivalence across the following critical parameters:

• Functional equivalence: Current Monitor with High-Side sensing method
• Electrical specifications: ±1% accuracy, 0V ~ 26V input voltage range, -25°C ~ 85°C operating temperature
• Package compatibility: 16-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected status
• Base product lineage: INA209 series designation

The substitute parts INA209AIPW and INA209AIPWR share identical electrical and mechanical specifications with the main part. The differences are limited to packaging format (Tube versus Cut Tape & Digi-Reel) and product status (Active versus Obsolete), which do not affect functional performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both INA209AIPW and INA209AIPWR are direct functional equivalents to the INA209AIPWG4. Selection between these substitutes should be based on procurement and assembly requirements:

INA209AIPW is suitable for applications where tube packaging is preferred for manual handling or small-volume assembly operations.

INA209AIPWR is recommended for high-volume production environments utilizing automated tape-and-reel assembly processes, with significantly higher inventory availability (16,400 units versus 1,504 units).

Both substitutes maintain full compliance with ROHS3 and REACH regulatory requirements. The transition from the obsolete INA209AIPWG4 to either active substitute presents no electrical or mechanical compatibility issues for existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can INA209AIPW and INA209AIPWR be used interchangeably with INA209AIPWG4?

A: Yes. Both substitutes are electrically and mechanically identical to the main part. The only differences are packaging format and product status. Circuit performance and PCB layout remain unchanged.

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

A: Tube packaging is used for manual component handling and lower-volume assembly. Cut tape with Digi-Reel packaging is designed for automated pick-and-place equipment in high-volume manufacturing. Both formats contain identical components.

Q: Does the obsolete status of INA209AIPWG4 affect its performance?

A: No. Product status indicates manufacturing availability, not functional capability. The INA209AIPWG4 performs identically to active variants. However, long-term supply continuity favors transition to active substitutes.

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

A: No. All three variants operate across the same temperature range (-25°C ~ 85°C) and maintain identical moisture sensitivity levels (MSL 2, 1 Year).

Q: Which substitute should be selected for new designs?

A: For new designs, either INA209AIPW or INA209AIPWR is appropriate. Selection depends on manufacturing volume and assembly process. INA209AIPWR is preferred for high-volume automated assembly due to superior inventory availability and tape-and-reel format compatibility.
