Engineering Selection Recommendations
Direct Functional Equivalents (General-Purpose Amplifiers):
AS358MMTR-G1 (Diodes Incorporated) and LM2904AQM8-13 (Diodes Incorporated) are functionally equivalent to the LM358DMR2G with identical circuit count, package format, and output current capability. Both parts are in active production status and maintain ROHS3 compliance with MSL rating of 1. AS358MMTR-G1 operates across -40°C to 85°C, while LM2904AQM8-13 extends to -40°C to 125°C and includes AEC-Q100 automotive qualification. Both parts support the full 3V to 36V supply range required by the LM358DMR2G application envelope.
LM258DGKR (Texas Instruments) provides functional equivalence with identical circuit count and supply voltage range. This part operates from -25°C to 85°C and is supplied in 8-VSSOP package format. Current supply is reduced to 500µA per channel compared to the LM358DMR2G specification.
Enhanced-Performance Alternatives (J-FET Amplifiers):
ADA4062-2ARMZ-R7 (Analog Devices Inc.) and ADTL082ARMZ-REEL (Analog Devices Inc.) offer superior electrical performance with J-FET input stages, delivering significantly lower input bias currents (2 pA versus 45 nA) and extended operating temperature ranges to -40°C to 125°C. These parts are in active production status with ROHS3 compliance. ADA4062-2ARMZ-R7 requires minimum 8V supply voltage, while ADTL082ARMZ-REEL provides higher gain-bandwidth product (5 MHz) and slew rate (20V/µs) at the cost of increased supply current.
Obsolete Part Status:
LM358DGKR (Rohm Semiconductor) is marked as obsolete and should not be selected for new designs despite functional compatibility with the LM358DMR2G.
Frequently Asked Questions (FAQ)
Q: Can the LM358DMR2G be directly replaced with AS358MMTR-G1?
A: Yes. Both parts feature two general-purpose amplifier circuits in 8-MSOP surface-mount packages with identical output current capability (40 mA per channel) and compatible supply voltage ranges (3V to 36V for AS358MMTR-G1 versus 3V to 32V for LM358DMR2G). Both are ROHS3 compliant with MSL rating of 1. The AS358MMTR-G1 operates across a wider temperature range (-40°C to 85°C) than the LM358DMR2G (0°C to 70°C).
Q: What is the primary difference between general-purpose and J-FET amplifier substitutes?
A: General-purpose amplifiers (AS358MMTR-G1, LM2904AQM8-13, LM258DGKR) use bipolar input stages with input bias currents in the 20 nA range. J-FET amplifiers (ADA4062-2ARMZ-R7, ADTL082ARMZ-REEL) use field-effect transistor input stages with input bias currents of 2 pA, approximately 10,000 times lower. J-FET devices also provide higher slew rates and gain-bandwidth products but require higher minimum supply voltages (8V versus 3V).
Q: Are there package compatibility considerations when substituting the LM358DMR2G?
A: The LM358DMR2G is supplied in 8-MSOP format. Direct substitutes AS358MMTR-G1, ADA4062-2ARMZ-R7, ADTL082ARMZ-REEL, and LM2904AQM8-13 are also available in 8-MSOP packages and are pin-compatible. LM258DGKR is supplied in 8-VSSOP format, which has different physical dimensions (0.118" width for 8-MSOP versus 0.118" width for 8-VSSOP) but maintains the same pin count and pinout. LM358DGKR uses 8-TSSOP format. Physical board layout verification is required when changing package formats.
Q: Which substitute part offers the lowest power consumption?
A: ADA4062-2ARMZ-R7 consumes 165µA per channel (330µA total for two channels), compared to 800µA for the LM358DMR2G. This represents a 59% reduction in supply current. However, this part requires a minimum 8V supply voltage, which may not be compatible with 3V to 5V single-supply applications.
Q: Can LM358DGKR be used as a substitute despite its obsolete status?
A: LM358DGKR is marked as obsolete and should not be selected for new designs. Although it provides functional equivalence with the LM358DMR2G, obsolete parts face supply discontinuation risk and may not be available for production quantities or future design revisions. Active-status alternatives such as AS358MMTR-G1 or LM2904AQM8-13 are recommended.
Q: What is the significance of MSL rating differences between substitute parts?
A: The LM358DMR2G, most substitute parts, and enhanced alternatives carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. AS358MMTR-G1 carries MSL rating of 3 (168 Hours), which requires controlled storage conditions and limits the time the component can be exposed to ambient humidity before soldering. For applications with standard manufacturing environments, MSL 1 rated parts are preferred.
Q: Are automotive-qualified substitutes available?
A: Yes. LM2904AQM8-13 (Diodes Incorporated) and BA3472YFVM-CTR (Rohm Semiconductor) both carry AEC-Q100 automotive qualification. LM2904AQM8-13 is a direct functional equivalent with extended temperature range (-40°C to 125°C). BA3472YFVM-CTR is a general-purpose amplifier with higher slew rate (10V/µs) and gain-bandwidth product (4 MHz) but operates in 8-VSSOP package format.
