Substitute Part Grouping Explanation

Substitution of the LPV511MGX is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for amplifier type, circuit count, output configuration, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, supply voltage range, operating temperature range, and package form factor.

The LPV511MGX/NOPB qualifies as a direct substitute based on the following key parameters:

• Amplifier Type: General Purpose (identical)
• Number of Circuits: 1 (identical)
• Output Type: Rail-to-Rail (identical)
• Slew Rate: 0.0077 V/µs (identical)
• Gain Bandwidth Product: 25 kHz (identical)
• Current - Input Bias: 320 pA (identical)
• Voltage - Input Offset: 200 µV (identical)
• Current - Supply: 1.2 µA (identical)
• Current - Output / Channel: 1.3 mA (identical)
• Voltage - Supply Span: 2.7 V to 12 V (identical)
• Operating Temperature: -40°C to 85°C (identical)
• Package / Case: 5-TSSOP, SC-70-5, SOT-353 (identical)

Parameter Comparison

Engineering Selection Recommendations

The LPV511MGX/NOPB is a direct electrical and mechanical equivalent to the obsolete LPV511MGX. All critical performance parameters, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, supply voltage range, and operating temperature specifications, are identical between the two devices.

The primary distinction is product status: the LPV511MGX is classified as obsolete, while the LPV511MGX/NOPB maintains active status. This substitution provides design continuity for applications requiring general-purpose rail-to-rail operational amplifier functionality in the SC-70-5 package.

Both devices comply with the same regulatory classifications (ECCN: EAR99; HTSUS: 8542.33.0001). The substitute part is available in bulk packaging, whereas the original part specification does not indicate a specific packaging format.
