Substitute Part Grouping Explanation
Substitute parts for the LMV358QD are classified into three functional groups based on electrical parameter compatibility:
Group 1: Direct Electrical Equivalents (Texas Instruments LMV358 Series) These parts maintain identical electrical specifications to the LMV358QD, including 1V/µs slew rate, 1MHz gain-bandwidth product, 15nA input bias current, and 40mA output current per channel. Substitution within this group is based on packaging format and product status (Active vs. Last Time Buy). Parts include LMV358QDR, LMV358M/NOPB, and LMV358MX/NOPB.
Group 2: Enhanced Performance Variants (Texas Instruments LMV358 Extended Range) The LMV358M/NOPB and LMV358MX/NOPB variants offer increased output current capability (160mA per channel) while maintaining core electrical parameters. These parts are suitable for applications requiring higher output drive capability within the same supply voltage and temperature operating range.
Group 3: Low-Power Alternatives (Texas Instruments LPV358 Series) The LPV358M/NOPB and LPV358MX/NOPB represent lower-power variants with reduced supply current (15µA vs. 210µA), lower slew rate (0.1V/µs vs. 1V/µs), and reduced gain-bandwidth product (152kHz vs. 1MHz). These parts are suitable for power-constrained applications but operate at reduced maximum temperature (85°C vs. 125°C).
Group 4: Cross-Manufacturer Equivalents Parts from Analog Devices (AD8542ARZ-REEL7), Diodes Incorporated (APX358SG-13, AZV358MTR-E1, AZV358MTR-G1), and Rohm Semiconductor (BU7242F-E2) provide functional equivalence with minor electrical parameter variations. These parts maintain dual-circuit, rail-to-rail, general-purpose amplifier functionality in compatible 8-pin surface-mount packages.
Key Substitution Criteria:
- Dual-circuit configuration (2 circuits per package)
- Rail-to-rail output capability

Frequently Asked Questions (FAQ)
Q1: Can LMV358QDR be used as a direct replacement for LMV358QD without circuit modification? Yes. The LMV358QDR maintains identical electrical specifications (1V/µs slew rate, 1MHz gain-bandwidth product, 15nA input bias current, 40mA output current per channel) and 8-SOIC packaging. No circuit modification is required.
Q2: What is the primary difference between LMV358M/NOPB and LMV358QD? The LMV358M/NOPB provides increased output current per channel (160mA vs. 40mA) while maintaining all other electrical specifications. This enhanced capability allows the part to drive higher-impedance loads without modification to the amplifier circuit topology.
Q3: Is LPV358MX/NOPB suitable for all applications currently using LMV358QD? No. The LPV358MX/NOPB operates at reduced bandwidth (152kHz vs. 1MHz) and reduced maximum temperature (85°C vs. 125°C). Applications requiring 1MHz bandwidth or operation above 85°C must use LMV358 series parts. Verification of application bandwidth and temperature requirements is necessary before selection.
Q4: What packaging differences exist between substitute parts? Most substitute parts use 8-SOIC (0.154", 3.90mm width) packaging, which is mechanically compatible with LMV358QD. The APX358SG-13 uses 8-SOP (0.154", 3.90mm width) packaging, which is mechanically similar but may require PCB layout verification. The BU7242F-E2 uses 8-SOP (0.173", 4.40mm width) packaging, which has different pin spacing and requires PCB redesign.
Q5: Which substitute part offers the lowest power consumption? The LPV358MX/NOPB offers the lowest supply current at 15µA (x2 channels) compared to 210µA for the LMV358QD. However, this part operates at reduced bandwidth (152kHz) and maximum temperature (85°C). The AD8542ARZ-REEL7 offers a compromise with 45µA supply current while maintaining 1MHz bandwidth and -40°C to 125°C temperature range.
Q6: Are all substitute parts ROHS3 compliant? Yes. All substitute parts listed maintain ROHS3 compliance status, ensuring regulatory compatibility with the original LMV358QD specification.
Q7: What is the difference between LMV358QDR and LMV358MX/NOPB packaging formats? LMV358QDR is supplied in Cut Tape (CT) & Digi-Reel format, while LMV358MX/NOPB is supplied in Cut Tape (CT) & Digi-Reel format. Both use 8-SOIC packaging. The primary difference is inventory availability and supplier packaging preference.
Q8: Can cross-manufacturer parts (Diodes, Analog Devices, Rohm) be used interchangeably with Texas Instruments LMV358 parts? Cross-manufacturer parts provide functional equivalence but may have minor electrical parameter variations. The AZV358MTR-G1 and AZV358MTR-E1 (Diodes) maintain identical specifications to LMV358QD. The AD8542ARZ-REEL7 (Analog Devices) has lower input bias current (4pA) and reduced supply current (45µA). The BU7242F-E2 (Rohm) has reduced bandwidth (900kHz) and lower output current (12mA). Selection requires verification that parameter variations are acceptable for the specific application.
Q9: What is the significance of "Last Time Buy" status for LMV358QD? Last Time Buy status indicates that Texas Instruments has discontinued production of the LMV358QD. Existing inventory will be depleted without replenishment. Designs currently using LMV358QD should transition to Active-status alternatives such as LMV358QDR, LMV358M/NOPB, or LMV358MX/NOPB to ensure long-term supply availability.
Q10: Which substitute part has the highest inventory availability? The LMV358MX/NOPB has the highest inventory availability with 155,100 units in stock. This part is suitable for applications requiring extended production runs or long-term supply security.
