Substitute Part Grouping Explanation
Substitution of the OP282GS-REEL is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:
Direct Equivalent Category: Parts that maintain identical electrical specifications across all key parameters including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. These parts are pin-compatible and functionally interchangeable without circuit modification.
Similar Performance Category: Parts that share the same amplifier type (J-FET), circuit count (2), package form factor (8-SOIC), and mounting type (Surface Mount), but exhibit variations in one or more electrical parameters such as slew rate, gain bandwidth product, input bias current, input offset voltage, or supply current. These parts require evaluation of application-specific tolerance to parameter deviations.
Compliance and Status Considerations: Product status (Active vs. Obsolete) and regulatory compliance (RoHS3, REACH) are secondary selection factors that support long-term supply chain viability and regulatory adherence.

Engineering Selection Recommendations
Direct Substitution (Recommended for Obsolete Part Replacement):
OP282GSZ-REEL is the primary direct equivalent to OP282GS-REEL. This part maintains identical electrical specifications across all parameters and is manufactured by Analog Devices Inc. with Active product status. OP282GSZ-REEL carries RoHS3 compliance and REACH Unaffected status, providing regulatory alignment for current manufacturing standards. The packaging difference (Cut Tape & Digi-Reel® vs. Reel) does not affect electrical performance and accommodates various procurement and assembly workflows.
Alternative J-FET Amplifiers (Conditional Substitution):
LT1057 series devices (LT1057IS8#PBF, LT1057IS8#TRPBF, LT1057S8#PBF, LT1057S8#TRPBF) are J-FET amplifiers with enhanced slew rate (13V/µs vs. 9V/µs) and higher gain bandwidth product (5 MHz vs. 4 MHz). These parts require minimum supply voltage of 20V, which exceeds the OP282GS-REEL minimum of 9V. Selection of LT1057 variants is appropriate only when circuit design accommodates the higher minimum supply voltage requirement and benefits from improved dynamic performance.
LT1113 series devices (LT1113CS8#PBF, LT1113CS8#TRPBF) and LT1169 series devices (LT1169CS8#PBF, LT1169CS8#TRPBF) are J-FET amplifiers with lower slew rate (3.9V/µs to 4.2V/µs) and higher supply current (5.3mA vs. 210µA). These parts are suitable for applications where the OP282GS-REEL's performance envelope is excessive and power consumption reduction is not a design constraint.
General Purpose Amplifier (Limited Compatibility):
AS358AMTR-E1 is a general purpose amplifier manufactured by Diodes Incorporated with Active product status. This device differs fundamentally in amplifier type (General Purpose vs. J-FET), input bias current (20nA vs. 3pA), and input offset voltage (2mV vs. 200µV). AS358AMTR-E1 is not recommended as a direct substitute for precision analog applications requiring the low input bias current and low input offset voltage characteristics of J-FET amplifiers.
Frequently Asked Questions (FAQ)
Q: Can OP282GSZ-REEL be used as a direct replacement for OP282GS-REEL?
A: Yes. OP282GSZ-REEL is electrically and functionally identical to OP282GS-REEL across all specified parameters. The primary difference is product status (Active vs. Obsolete) and packaging format (Cut Tape & Digi-Reel® vs. Reel). Both parts are pin-compatible 8-SOIC surface mount devices with identical electrical performance.
Q: What are the key differences between OP282GS-REEL and LT1057 series devices?
A: LT1057 series devices offer higher slew rate (13V/µs vs. 9V/µs) and higher gain bandwidth product (5 MHz vs. 4 MHz), but require a minimum supply voltage of 20V compared to 9V for OP282GS-REEL. LT1057 devices are suitable for applications requiring faster transient response and higher bandwidth, provided the circuit design accommodates the higher minimum supply voltage.
Q: Are LT1113 and LT1169 series devices suitable replacements for OP282GS-REEL?
A: LT1113 and LT1169 series devices share the same J-FET amplifier type and 8-SOIC package, but exhibit lower slew rate and significantly higher supply current consumption. These parts are appropriate only when the application does not require the OP282GS-REEL's low power consumption characteristics and can tolerate reduced slew rate performance.
Q: Why is AS358AMTR-E1 not recommended as a substitute?
A: AS358AMTR-E1 is a general purpose amplifier with fundamentally different input characteristics. Input bias current is 20nA (versus 3pA for OP282GS-REEL) and input offset voltage is 2mV (versus 200µV). These differences make AS358AMTR-E1 unsuitable for precision analog applications requiring the low input bias current and low input offset voltage performance of J-FET amplifiers.
Q: What packaging options are available for OP282 equivalent devices?
A: OP282GSZ-REEL is available in Cut Tape & Digi-Reel® packaging. All substitute J-FET amplifiers (LT1057, LT1113, LT1169 series) are available in both Tube and Tape & Reel (TR) packaging formats. All devices maintain the 8-SOIC (0.154", 3.90mm Width) surface mount package form factor.
Q: Are all substitute parts RoHS3 compliant?
A: OP282GSZ-REEL, LT1057 series, LT1113 series, LT1169 series, and AS358AMTR-E1 are all RoHS3 compliant. All parts carry REACH Unaffected status, supporting current regulatory requirements for electronic component manufacturing and distribution.
Q: What is the operating temperature range difference between OP282GS-REEL and substitute parts?
A: OP282GS-REEL operates across -40°C to 85°C. LT1057IS8#PBF, LT1057IS8#TRPBF, LT1113CS8#PBF, and LT1113CS8#TRPBF maintain this temperature range. LT1057S8#PBF, LT1057S8#TRPBF, LT1169CS8#PBF, and LT1169CS8#TRPBF operate across 0°C to 70°C, which is narrower. AS358AMTR-E1 operates across -40°C to 85°C. Temperature range selection depends on application environmental requirements.
