Substitution of the THS4131CDGKG4 is determined by strict equivalence across the following critical parameters:

Electrical Performance Parameters:

• Amplifier type: Differential
• Number of circuits: 1
• Output type: Differential
• Slew rate: 52 V/µs
• Gain bandwidth product: 225 MHz
• -3dB bandwidth: 150 MHz
• Input bias current: 2 µA
• Input offset voltage: 200 µV
• Supply current: 12.3 mA
• Supply voltage range: 4 V to 33 V

Physical and Environmental Parameters:

• Package type: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
• Mounting type: Surface Mount
• Operating temperature range: 0°C to 70°C

Compliance Parameters:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part THS4131CDGK meets all electrical performance specifications and environmental requirements. The primary difference is packaging format (Tube versus the original specification), which does not affect functional compatibility in applications where the component specifications are met.

Parameter Comparison

Engineering Selection Recommendations

The THS4131CDGK is a direct functional equivalent to the THS4131CDGKG4. Both components are manufactured by Texas Instruments and share identical electrical specifications, package dimensions, and compliance certifications.

Selection Basis:

The substitute part THS4131CDGK maintains full compatibility with applications designed for the THS4131CDGKG4 based on:

• Identical electrical performance across all specified parameters
• Identical package footprint and mounting requirements
• Identical operating temperature range
• Identical RoHS3 compliance and moisture sensitivity classification
• Same base product number (THS4131) indicating common design lineage

The difference in packaging format (Tube versus Tape and Reel) does not affect component functionality or circuit performance. This difference relates only to supply and handling logistics.

Both components are classified as obsolete products. Inventory availability should be verified through authorized distributors prior to procurement decisions.
