Substitute Part Grouping Explanation

Substitution of the OP497GS-REEL is determined by equivalence in the following critical parameters: amplifier type classification, number of circuits, package form factor, mounting technology, and operating temperature range. The OP497GS-REEL operates as a general purpose amplifier with four independent circuits in a 16-SOIC surface mount package rated for -40°C to 85°C operation.

Substitute parts are grouped into two categories:

Category 1: Direct Functional Equivalents — Parts that maintain identical amplifier type (general purpose), circuit count (4), package geometry (16-SOIC), and operating temperature range (-40°C to 85°C). These parts differ only in product status (active versus obsolete) and packaging format (reel, tube, or tape & reel).

Category 2: Functional Alternatives with Parameter Variations — Parts that maintain the 4-circuit configuration and 16-SOIC package but differ in amplifier type (J-FET versus general purpose), slew rate, gain bandwidth product, supply current, or operating temperature range. These alternatives are suitable when the application tolerates the specified parameter deviations.

The key parameters determining substitution eligibility are: number of circuits (4), package type (16-SOIC), mounting method (surface mount), and operating temperature minimum (-40°C).

Engineering Selection Recommendations

Primary Substitute: OP497GSZ-REEL

The OP497GSZ-REEL is the direct active equivalent of the OP497GS-REEL. This part maintains identical electrical specifications across all measured parameters: slew rate (0.15 V/µs), gain bandwidth product (500 kHz), input bias current (60 pA), input offset voltage (80 µV), supply current (525 µA across four channels), and output current per channel (25 mA). The operating temperature range (-40°C to 85°C) and package form factor (16-SOIC, 0.295" width) are identical. The OP497GSZ-REEL is classified as active product status, ensuring ongoing availability and manufacturing support. This part is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Secondary Substitutes: General Purpose Amplifiers

The LT1114IS and LT1114S are general purpose 4-circuit amplifiers in 16-SOIC packages suitable for applications where slightly elevated slew rate (0.3 V/µs) and gain bandwidth product (750 kHz) are acceptable. Both parts maintain the 25 mA output current per channel and support the full 4 V to 40 V supply range. The LT1114IS extends the operating temperature to -40°C to 85°C, matching the original specification. The LT1114S operates over 0°C to 70°C, requiring temperature range verification for the target application.

The LT1079ISW#TRPBF is a general purpose amplifier with lower power consumption (39 µA total supply current) and reduced slew rate (0.1 V/µs), suitable for low-power applications. This part operates at -40°C to 85°C but requires verification of the reduced minimum supply voltage (2.2 V) against circuit requirements.

Tertiary Substitutes: J-FET Amplifiers

The LT1058 series (LT1058ISW, LT1058ISW#PBF, LT1058ISW#TRPBF, LT1058SW#PBF, LT1058SW#TRPBF) represents J-FET input amplifiers with significantly enhanced performance characteristics: slew rate of 13 V/µs and gain bandwidth product of 5 MHz. These parts are suitable only when the application requires higher speed operation and can tolerate the increased supply current (1.7 mA across four channels) and higher input offset voltage (350 µV). The LT1058I variants support -40°C to 85°C operation, while LT1058S variants are limited to 0°C to 70°C. All LT1058 variants require minimum supply voltage of 20 V, which may restrict use in lower-voltage applications.

High-Performance Alternative: LT1125CSW

The LT1125CSW is a high-performance general purpose amplifier with slew rate of 4.5 V/µs and gain bandwidth product of 12.5 MHz. This part is suitable for applications requiring significantly enhanced bandwidth and speed performance. The LT1125CSW operates over 0°C to 70°C and requires minimum supply voltage of 8 V. Supply current is elevated to 2.3 mA across four channels.

All recommended substitutes are manufactured by Analog Devices Inc., carry RoHS3 compliance certification, and are classified as active products with established supply chains.

Frequently Asked Questions (FAQ)

Q: Can OP497GSZ-REEL be used as a direct replacement for OP497GS-REEL?

A: Yes. The OP497GSZ-REEL is electrically and mechanically identical to the OP497GS-REEL. Both parts share identical slew rate (0.15 V/µs), gain bandwidth product (500 kHz), input bias current (60 pA), input offset voltage (80 µV), supply current (525 µA), output current (25 mA per channel), supply voltage range (4 V to 40 V), operating temperature range (-40°C to 85°C), and 16-SOIC package form factor. The primary difference is product status: OP497GSZ-REEL is active, while OP497GS-REEL is obsolete. The OP497GSZ-REEL is the recommended substitute for new designs and production continuity.

Q: What is the difference between the LT1058 and OP497 series?

A: The LT1058 is a J-FET input amplifier, while the OP497 is a general purpose amplifier. The LT1058 provides superior speed performance with slew rate of 13 V/µs (versus 0.15 V/µs for OP497) and gain bandwidth product of 5 MHz (versus 500 kHz for OP497). However, the LT1058 exhibits higher input offset voltage (350 µV versus 80 µV) and increased supply current (1.7 mA versus 525 µA). The LT1058 requires minimum supply voltage of 20 V, while the OP497 operates from 4 V. The LT1058 is suitable only when the application requires the enhanced speed characteristics and can accommodate the increased power consumption and higher input offset voltage.

Q: Are all substitute parts available in the same packaging formats?

A: No. The OP497GSZ-REEL is available in Cut Tape and Digi-Reel format. The LT1058 series is available in multiple packaging options: standard tube (LT1058ISW#PBF, LT1058SW#PBF) and Tape & Reel (LT1058ISW#TRPBF, LT1058SW#TRPBF). The LT1079ISW#TRPBF is available in Tape & Reel format only. The LT1114IS and LT1114S do not specify packaging format in the provided data. Packaging format selection depends on production volume, assembly equipment compatibility, and inventory management requirements.

Q: Can LT1114IS be used in applications requiring -40°C to 85°C operation?

A: Yes. The LT1114IS supports the full -40°C to 85°C operating temperature range, matching the OP497GS-REEL specification. The LT1114S variant is limited to 0°C to 70°C operation and is not suitable for applications requiring extended low-temperature performance.

Q: What are the supply voltage constraints when substituting with LT1058 or LT1079 parts?

A: The LT1058 series requires minimum supply voltage of 20 V, compared to 4 V for the OP497GS-REEL. Applications operating at supply voltages below 20 V cannot use the LT1058. The LT1079ISW#TRPBF operates from 2.2 V minimum, which is lower than the OP497GS-REEL (4 V minimum), providing greater flexibility for low-voltage applications.

Q: Is the LT1125CSW suitable as a substitute for the OP497GS-REEL?

A: The LT1125CSW is suitable only for applications where the enhanced performance characteristics are required and the operating temperature range can be restricted to 0°C to 70°C. The LT1125CSW provides significantly higher slew rate (4.5 V/µs) and gain bandwidth product (12.5 MHz), but requires minimum supply voltage of 8 V and exhibits higher supply current (2.3 mA). The LT1125CSW is not a direct substitute but rather a performance upgrade option for bandwidth-critical applications.

Q: What compliance certifications apply to the substitute parts?

A: All recommended substitute parts are RoHS3 compliant and REACH unaffected. The OP497GSZ-REEL, LT1058 series, LT1079ISW#TRPBF, LT1114IS, LT1114S, and LT1125CSW all carry these certifications, ensuring compliance with current environmental and regulatory requirements for electronic components.
