1. OP-07DPSR Substitution Conclusion
The OP-07DPSR exhibits high similarity to the original OP07CSZ in core electrical parameters, including gain bandwidth product (600 kHz), slew rate (0.3 V/µs), input offset voltage (60 µV), and supply voltage range (6 V to 36 V). However, two key differences exist: first, the package width is 5.30 mm (compared to 3.90 mm for the original). If the original PCB layout is designed for a narrow-body SOIC, direct substitution may result in physical incompatibility, requiring reassessment of space or layout adjustments. Second, the input bias current is 2 nA (versus 1.8 nA for the original). This difference is generally negligible in typical applications but may introduce slight errors in very high-precision or low-noise systems. Provided package compatibility is verified, the OP-07DPSR can serve as an electrical substitute, though physical fit must be carefully considered.
2. OP07CDR Substitution Conclusion
The OP07CDR matches the original OP07CSZ in all key performance parameters, including gain bandwidth product (600 kHz, equivalent to the original -3 dB bandwidth), slew rate (0.3 V/µs), input offset voltage (60 µV), input bias current (1.8 nA), and supply voltage range (6 V to 36 V). Additionally, the package dimensions are identical—both are 8-SOIC with a width of 3.90 mm. This indicates no differences in electrical characteristics or physical footprint. The OP07CDR can directly replace the OP07CSZ without any circuit modifications or PCB layout changes, making it an ideal drop-in substitute suitable for a wide range of standard amplification applications.
