Substitute Part Grouping Explanation

Substitution of the LT6375HDF is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for amplifier type, circuit count, output configuration, slew rate, bandwidth, input offset voltage, supply current, output current capability, supply voltage range, operating temperature range, and physical package dimensions.

The LT6375HDF#PBF qualifies as a direct substitute based on the following key parameters:

• Amplifier Type: Differential (identical)
• Number of Circuits: 1 (identical)
• Output Type: Rail-to-Rail (identical)
• Slew Rate: 2.4V/µs (identical)
• -3dB Bandwidth: 575 kHz (identical)
• Voltage - Input Offset: 120 µV (identical)
• Current - Supply: 350µA (identical)
• Current - Output / Channel: 28 mA (identical)
• Voltage - Supply Span: 3V to 50V (identical)
• Operating Temperature: -40°C to 125°C (identical)
• Package / Case: 14-WFDFN Exposed Pad, 12 Leads (identical)
• Mounting Type: Surface Mount (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Parameter Comparison

Engineering Selection Recommendations

The LT6375HDF#PBF is the direct equivalent substitute for the obsolete LT6375HDF. Both parts share identical electrical and mechanical specifications across all critical parameters including amplifier topology, bandwidth, slew rate, supply voltage range, and package configuration.

The primary distinction between the two parts is product status: the LT6375HDF is obsolete, while the LT6375HDF#PBF maintains active status with current manufacturing support. The substitute part is supplied in tube packaging and carries ROHS3 compliance and REACH unaffected certification, providing regulatory alignment for modern production environments.

For new designs or ongoing production requiring this differential amplifier topology, the LT6375HDF#PBF is the appropriate selection. The active product status ensures continued availability, manufacturing support, and supply chain reliability. Electrical and mechanical compatibility is complete, requiring no circuit redesign or board layout modification.
