Substitute Part Grouping Explanation
Substitution of the OP177FPZ is determined by alignment across the following critical parameters:
Mechanical Compatibility: All substitute parts must use the 8-DIP (0.300", 7.62mm) through-hole package to ensure direct socket compatibility without PCB redesign.
Electrical Compatibility: Substitute parts must operate within the supply voltage range of 6V to 36V and maintain single-circuit configuration. The slew rate, gain bandwidth product, input bias current, and input offset voltage define performance boundaries for signal conditioning applications.
Thermal Compatibility: Operating temperature range determines application suitability. The OP177FPZ operates from -40°C to 85°C, establishing the baseline for industrial and extended-temperature applications.
Regulatory Compliance: RoHS3 compliance and REACH unaffected status are required for modern design standards.
Substitute parts are grouped into two categories:
Direct Equivalents (Pin-Compatible, Electrical Match): OPA177FP and OPA177GP maintain identical slew rate (0.3V/µs), gain bandwidth product (600 kHz), supply voltage range (6V to 36V), and operating temperature range (-40°C to 85°C). These parts are interchangeable for applications where the OP177FPZ specifications are the design requirement.
Functional Alternatives (Pin-Compatible, Enhanced Performance): LT1360CN8#PBF provides significantly higher slew rate (800V/µs) and gain bandwidth product (50 MHz) while maintaining 8-DIP package compatibility. This part is suitable for applications requiring faster signal response but operates within a narrower supply voltage range (5V to 30V) and temperature range (0°C to 70°C).
Similar Alternatives (Pin-Compatible, Legacy Compatibility): OP07CP and OP07DP maintain the same slew rate and bandwidth as the OP177FPZ but differ in input bias current and offset voltage specifications. These parts support legacy design migration.

Engineering Selection Recommendations
For Direct Replacement with Identical Performance:
OPA177FP and OPA177GP are direct electrical equivalents to the OP177FPZ. Both parts maintain the same slew rate (0.3V/µs), gain bandwidth product (600 kHz), supply voltage range (6V to 36V), and operating temperature range (-40°C to 85°C). OPA177FP is currently in Last Time Buy status with 2300 units available. OPA177GP is also in Last Time Buy status with 3933 units available. Both parts are ROHS3 compliant and suitable for applications where the OP177FPZ electrical specifications define the design baseline.
For Enhanced Performance Applications:
LT1360CN8#PBF provides a significant performance upgrade with 800V/µs slew rate and 50 MHz gain bandwidth product, compared to the OP177FPZ baseline of 0.3V/µs and 600 kHz. This part is suitable for applications requiring faster transient response and higher frequency operation. The LT1360CN8#PBF operates within a narrower supply voltage range (5V to 30V) and temperature range (0°C to 70°C). This part is currently in active production with 1147 units in stock and is ROHS3 compliant.
For Legacy System Compatibility:
OP07CP maintains electrical compatibility with the OP177FPZ across slew rate, bandwidth, and supply voltage parameters. This part is currently active with 21974 units in stock and is ROHS3 compliant. OP07DP is obsolete and RoHS non-compliant, making it unsuitable for new designs.
Compliance Considerations:
All recommended substitutes (OPA177FP, OPA177GP, OP07CP, and LT1360CN8#PBF) are ROHS3 compliant and REACH unaffected. OP07DP is RoHS non-compliant and should not be selected for applications requiring regulatory compliance.
Frequently Asked Questions (FAQ)
Q: Can OPA177FP be used as a direct replacement for OP177FPZ?
A: Yes. OPA177FP maintains identical electrical specifications including slew rate (0.3V/µs), gain bandwidth product (600 kHz), supply voltage range (6V to 36V), and operating temperature range (-40°C to 85°C). The 8-DIP package is identical, enabling direct socket substitution. OPA177FP is manufactured by Texas Instruments and is ROHS3 compliant.
Q: What is the difference between OPA177FP and OPA177GP?
A: Both parts are electrically equivalent to the OP177FPZ with identical slew rate, bandwidth, and supply voltage specifications. The primary difference is input offset voltage: OPA177FP specifies 10 µV maximum, while OPA177GP specifies 20 µV maximum. Both are in Last Time Buy status. Selection depends on offset voltage tolerance requirements for the application.
Q: When should LT1360CN8#PBF be selected instead of OP177FPZ?
A: LT1360CN8#PBF should be selected when the application requires significantly higher slew rate (800V/µs versus 0.3V/µs) and gain bandwidth product (50 MHz versus 600 kHz). This part is suitable for high-speed signal conditioning and fast transient applications. The supply voltage range is narrower (5V to 30V versus 6V to 36V), and the operating temperature range is reduced (0°C to 70°C versus -40°C to 85°C). Pin compatibility is maintained in the 8-DIP package.
Q: Is OP07DP suitable for new designs?
A: No. OP07DP is obsolete and RoHS non-compliant. It should not be selected for new designs. OP07CP is the active equivalent from Texas Instruments and is ROHS3 compliant.
Q: Are all substitute parts available in the same package?
A: Yes. All substitute parts listed (OPA177FP, OPA177GP, OP07CP, OP07DP, and LT1360CN8#PBF) are housed in the 8-DIP (0.300", 7.62mm) through-hole package, enabling direct PCB compatibility without layout modifications.
Q: What is the supply voltage compatibility range for substitution?
A: The OP177FPZ operates from 6V to 36V. OPA177FP, OPA177GP, OP07CP, and OP07DP all support this range. LT1360CN8#PBF operates from 5V to 30V, which is a subset of the OP177FPZ range. Designs operating above 30V supply voltage cannot use LT1360CN8#PBF.
Q: What is the operating temperature range compatibility?
A: The OP177FPZ operates from -40°C to 85°C. OPA177FP and OPA177GP maintain this range. OP07CP, OP07DP, and LT1360CN8#PBF operate from 0°C to 70°C. Applications requiring operation below 0°C or above 70°C must use OPA177FP, OPA177GP, or the original OP177FPZ.
Q: Are all substitute parts RoHS compliant?
A: OPA177FP, OPA177GP, OP07CP, and LT1360CN8#PBF are ROHS3 compliant. OP07DP is RoHS non-compliant and should not be used in applications requiring regulatory compliance.
Q: What is the current inventory status for each substitute?
A: OPA177FP has 2300 units available (Last Time Buy status). OPA177GP has 3933 units available (Last Time Buy status). OP07CP has 21974 units available (Active status). LT1360CN8#PBF has 1147 units available (Active status). OP07DP has 3694 units available (Obsolete status).
