LT1012S8#TRPBF is electrically compatible and shares the same 8-SOIC package and operating temperature range (0°C to 70°C). However, it features different slew rate (0.2 V/µs), significantly lower input bias current (25 pA), and lower input offset voltage (8 µV). Applications sensitive to these parameter differences require circuit validation before substitution.
Q7: What is the supply voltage compatibility range for substitute parts?
OP07CDR, OP07CSZ variants, and OP07DRZ variants all support 6 V to 36 V supply range, matching OP07CDRE4. LT1012S8#TRPBF supports a wider range (2.4 V to 40 V). AD621BRZ supports 4.6 V to 36 V. Verify supply voltage requirements before selection.
