Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP191GS-REEL7 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for:

• Amplifier type and circuit configuration (General Purpose, 1 Circuit)
• Output characteristics (Rail-to-Rail)
• Frequency response (3 MHz gain bandwidth product)
• Slew rate (0.5 V/µs)
• Input bias current (30 nA)
• Input offset voltage (80 µV)
• Supply current (260 µA)
• Output current capability (16 mA per channel)
• Supply voltage range (2.7V to 12V)
• Operating temperature range (-40°C to 125°C)
• Physical package (8-SOIC with 3.90mm width)
• Moisture sensitivity classification (MSL 1)

The OP191GSZ-REEL7 meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The OP191GSZ-REEL7 is the direct substitute for the obsolete OP191GS-REEL7. Both parts are manufactured by Analog Devices Inc. and share identical electrical and mechanical specifications across all parameters.

The OP191GSZ-REEL7 offers the advantage of active product status, ensuring ongoing availability and manufacturing support. This part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

The packaging format difference (Cut Tape and Digi-Reel® for the substitute versus standard reel for the main part) does not affect electrical performance or functional compatibility. Both parts utilize the same 8-SOIC package geometry and are suitable for identical PCB layouts and assembly processes.
