Substitute Part Grouping Explanation

Substitution of the obsolete THS4061CDG4 is determined by electrical and mechanical parameter equivalence within the voltage feedback amplifier category. The primary substitution criteria are:

Electrical Parameters: Slew rate (400V/µs), -3dB bandwidth (180 MHz), input bias current (3 µA), input offset voltage (2.5 mV), supply current (7.8mA), output current per channel (115 mA), and supply voltage range (9V to 33V) must remain identical.

Mechanical Parameters: Package type (8-SOIC), mounting method (surface mount), and physical dimensions (0.154" width, 3.90mm) must be preserved.

Compliance Parameters: RoHS3 compliance and MSL rating (1 - Unlimited) must be maintained.

Functional Parameters: Amplifier type (voltage feedback) and circuit count (1 circuit) must be consistent.

The substitute part THS4061CD meets all specified criteria while offering active product status and improved availability.
