Engineering Selection Recommendations
Primary Substitutes (Direct Equivalents):
LM258DR2G (onsemi) and LM258DT (STMicroelectronics) are the preferred substitutes for the LM258DRG3. Both maintain the LM258 base product designation, ensuring functional and pin-level compatibility. LM258DR2G is Active status with identical supply voltage range (3V to 32V), matching input offset voltage (2 mV), and equivalent output current (40 mA). LM258DT offers enhanced performance with higher slew rate (0.6 V/µs) and gain bandwidth product (1.1 MHz) while maintaining the same supply range and output current specifications. Both are ROHS3 compliant with MSL 1 rating.
Secondary Substitutes (Enhanced Performance):
ISL28207FBZ and ISL28207FBZ-T13 (Renesas Electronics) provide superior performance characteristics including lower input bias current (15 pA), lower input offset voltage (5 µV), higher gain bandwidth product (1 MHz), and extended operating temperature range (-40°C to 125°C). These devices maintain 8-SOIC package compatibility and 40 mA output current. The extended supply voltage maximum (40V) provides additional design flexibility. MSL rating is 2 (1 Year), requiring appropriate moisture control during storage and assembly.
Alternative Consideration (Different Amplifier Type):
ADA4062-2BRZ (Analog Devices Inc.) is a J-FET amplifier variant with significantly enhanced performance (3.3 V/µs slew rate, 1.4 MHz GBW, 2 pA input bias current) but operates with minimum supply voltage of 8V, making it unsuitable for 3V supply applications. This device is excluded from direct substitution due to amplifier type classification and supply voltage incompatibility.
Inventory and Availability:
LM258DR2G (onsemi) offers the highest inventory availability at 505,200 pieces. LM258DT (STMicroelectronics) provides 125,300 pieces. ISL28207FBZ (Renesas) has 1,900 pieces available. All recommended substitutes are Active status products with established supply chains.
Frequently Asked Questions (FAQ)
Q: Can the LM258DRG3 be directly replaced with LM258DR2G?
A: Yes. LM258DR2G is a direct functional equivalent sharing the same LM258 base product number, identical 8-SOIC package footprint, and compatible electrical specifications including 3V to 32V supply range, 40 mA output current per channel, and -25°C to 85°C operating temperature. Both are ROHS3 compliant with MSL 1 rating.
Q: What is the difference between LM258DT and LM258WDT?
A: LM258DT is a commercial-grade device with -25°C to 85°C operating range. LM258WDT is an automotive-qualified variant (AEC-Q100) with extended temperature range (-40°C to 105°C) and higher output current (60 mA vs. 40 mA). Both share identical slew rate (0.6 V/µs) and gain bandwidth product (1.1 MHz). Selection depends on application temperature requirements and automotive qualification necessity.
Q: Why is the AD706JRZ-REEL not recommended as a primary substitute?
A: While AD706JRZ-REEL is a general-purpose amplifier in 8-SOIC package, it has reduced output current capability (15 mA vs. 40 mA) and narrower operating temperature range (0°C to 70°C vs. -25°C to 85°C). Additionally, the minimum supply voltage is 4V, incompatible with 3V supply applications. These limitations restrict its use to specific applications with higher supply voltages and lower output current requirements.
Q: Are ISL28207FBZ and ISL28207FBZ-T13 interchangeable?
A: ISL28207FBZ and ISL28207FBZ-T13 are electrically identical with identical specifications. The primary difference is packaging: ISL28207FBZ uses standard Cut Tape packaging, while ISL28207FBZ-T13 uses Tape & Reel format. Selection depends on assembly process requirements. Both have MSL 2 rating requiring 1-year moisture control compliance.
Q: Can the LM258DRG3 be used in automotive applications?
A: The LM258DRG3 is not automotive-qualified. For automotive applications requiring AEC-Q100 qualification, use LM258WDT or LM258WYDT (STMicroelectronics), both carrying automotive grade designation and AEC-Q100 qualification with extended temperature range (-40°C to 105°C).
Q: What is the impact of MSL rating on component handling?
A: LM258DRG3, LM258DR2G, LM258DT, LM258WDT, and LM258WYDT have MSL 1 (Unlimited) rating, requiring no special moisture control. ISL28207FBZ and ISL28207FBZ-T13 have MSL 2 (1 Year) rating, requiring storage in dry conditions and baking before reflow if exposed to ambient humidity for extended periods. Verify moisture control procedures with assembly specifications.
Q: Is package width variation significant between substitutes?
A: BA10358F-E2 has package width of 0.173" (4.40mm) compared to 0.154" (3.90mm) for all other substitutes. This dimensional difference may affect PCB layout compatibility, particularly in high-density designs. Verify footprint compatibility before design implementation. All other substitutes maintain identical 0.154" (3.90mm) width.
Q: What supply voltage range should be verified for each substitute?
A: LM258DRG3 operates 3V to 32V. LM258DR2G and LM258DR operate 3V to 32V. LM258DT, LM258WDT, and LM258WYDT operate 3V to 30V (1V lower maximum). AD706JRZ-REEL operates 4V to 36V (1V higher minimum). ISL28207FBZ and ISL28207FBZ-T13 operate 4.5V to 40V. Verify application supply voltage compatibility before substitution.
