Possible Alternative Parts
Part Number:LM258ADT
Manufacturer:STMicroelectronics
Availability:0
Pricing$0.46
SkyChip No.:J4RP6-LM258ADTTR
Part Number:LM258AYDT
Manufacturer:STMicroelectronics
Availability:0
Pricing$0.9
SkyChip No.:V4ZWX-LM258AYDTTR
Substitution Analysis:In the vast majority of applications requiring high-performance JFET input stages, the LM258AYDT cannot directly substitute the LT1457S8TRPBF. It may only be considered in limited, general-purpose ... View More
Part Number:LM258D
Manufacturer:Texas Instruments
Availability:0
Pricing$0
SkyChip No.:NEAZ2-LM258DT
Substitution Analysis:The LM258D is not a viable direct replacement for the LT1457S8. The key differences are its high input bias current of 20nA (vs. 7pA for the LT1457), input offset voltage of 3mV (vs. 220µV), and its ... View More
Part Number:LM258DG4
Manufacturer:Texas Instruments
Availability:676
Pricing$0.58
SkyChip No.:NVLKO-LM258DG4T
Substitution Analysis:The LM258DG4 is mechanically compatible with the original LT1457S8TRPBF in physical package (8-SOIC) and dual-channel configuration. However, significant electrical performance differences limit its ... View More
Part Number:LM258DR
Manufacturer:Texas Instruments

Pricing$0.18
SkyChip No.:KEPF9-LM258DRTR
Part Number:LM258DRG3
Manufacturer:Texas Instruments
Availability:0
Pricing$0
SkyChip No.:EBN6E-LM258DRG3TR
Substitution Analysis:Similarly, the LM258DRG3 cannot serve as a direct replacement for the LT1457S8TRPBF. Its performance gap is even more pronounced than that of the LM258AYDT, limiting its suitability to only the least ... View More
Part Number:LM258DRG4
Manufacturer:Texas Instruments
Availability:71
Pricing$0
SkyChip No.:6X138-LM258DRG4TR
Substitution Analysis:The LM258DRG4 shares essentially the same parameters as the LM258DG4, but with a further reduced gain-bandwidth product of 700 kHz. This makes it an even less viable substitute for the original ... View More
Part Number:LM2904AYDT
Manufacturer:STMicroelectronics
Availability:0
Pricing$0.34
SkyChip No.:IC66T-LM2904AYDTTR
Part Number:MC34072DR2G
Manufacturer:onsemi
Availability:0
Pricing$0.42
SkyChip No.:D75PZ-MC34072DR2GTR
Substitution Analysis:Direct substitution is not recommended due to fundamental architectural differences that lead to significant parameter deviations. The MC34072DR2G is a standard bipolar‑input op‑amp (not J‑FET). Its ... View More
