Substitute Part Grouping Explanation

Substitute parts for the INA106UG4 are identified based on strict electrical and mechanical parameter equivalence. All substitute candidates share identical specifications across the following critical parameters:

• Amplifier Type: Differential
• Number of Circuits: 1
• Slew Rate: 3 V/µs
• -3dB Bandwidth: 1 MHz
• Voltage - Input Offset: 50 µV
• Current - Supply: 1.5 mA
• Current - Output / Channel: 20 mA
• Voltage - Supply Span: 10 V to 36 V
• Operating Temperature Range: 0°C to 70°C
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

The substitute parts differ only in packaging format (Tube or Tape & Reel) and product status, with no variation in electrical performance or functional characteristics.

Parameter Comparison

Engineering Selection Recommendations

INA106U/2K5 is the primary substitute for the INA106UG4. This part maintains active product status with Texas Instruments and is supplied in Tape & Reel format, supporting high-volume manufacturing and automated assembly processes. All electrical parameters, thermal specifications, and compliance certifications are identical to the original part.

INA106U serves as a secondary substitute option. This part is classified as obsolete but remains functionally equivalent across all electrical and mechanical parameters. The INA106U is supplied in Tube packaging, suitable for lower-volume applications or manual assembly workflows.

Both substitute parts satisfy ROHS3 compliance requirements and maintain identical moisture sensitivity specifications. Selection between INA106U/2K5 and INA106U depends on procurement volume requirements and assembly methodology rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can INA106U/2K5 be used as a direct replacement for INA106UG4?

A: Yes. The INA106U/2K5 is electrically and mechanically equivalent to the INA106UG4. All functional parameters, supply voltage ranges, bandwidth specifications, and package dimensions are identical. The difference is packaging format: INA106U/2K5 uses Tape & Reel format while INA106UG4 uses standard packaging.

Q: What is the difference between INA106U and INA106U/2K5?

A: Both parts are electrically identical with matching performance specifications. The primary difference is packaging: INA106U is supplied in Tube format, while INA106U/2K5 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly, while Tube packaging is suitable for manual handling and lower-volume applications.

Q: Why is INA106UG4 discontinued?

A: The INA106UG4 is discontinued at DiGi Electronics. However, functionally equivalent alternatives remain available through the INA106 product family, specifically INA106U/2K5 (active status) and INA106U (obsolete status).

Q: Are there any electrical performance differences between the substitute parts?

A: No. All three parts—INA106UG4, INA106U, and INA106U/2K5—share identical electrical specifications including slew rate (3 V/µs), bandwidth (1 MHz), input offset voltage (50 µV), supply current (1.5 mA), and output current capability (20 mA).

Q: Can the 8-SOIC package be used interchangeably on the same PCB?

A: Yes. All three parts use the 8-SOIC package with identical dimensions (0.154" width, 3.90mm). PCB footprints and land patterns are compatible across all substitute options.

Q: What compliance certifications apply to the substitute parts?

A: Both INA106U and INA106U/2K5 are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original INA106UG4. Moisture sensitivity level is 3 (168 Hours) for all parts.
