Substitute Part Grouping Explanation

Substitute parts for the LMV341IDBVRG4 are identified based on electrical and mechanical compatibility within the LMV341 base product family. The substitution logic is determined by the following criteria:

Primary Substitution Criteria:

• Base Product Number: LMV341
• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Slew Rate: 1 V/µs
• Gain Bandwidth Product: 1 MHz
• Voltage - Input Offset: 250 µV
• Current - Supply: 107 µA
• Current - Output / Channel: 113 mA
• Operating Temperature: -40°C to 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Package Considerations: Substitute parts are grouped into two categories based on package type: SOT-23-6 (direct package match) and SC-70-6 (alternative package). Package selection depends on PCB layout requirements and mechanical constraints.

Supply Voltage Compatibility: The LMV341IDBVRG4 operates at 2.5 V minimum supply voltage. Substitute parts LMV341MG/NOPB and LMV341MGX/NOPB operate at 2.7 V minimum, which is compatible with applications designed for the original part's 2.5 V specification when supply voltage is maintained at or above 2.7 V.

Engineering Selection Recommendations

LMV341IDBVR (Primary Substitute)

The LMV341IDBVR is the recommended primary substitute for the obsolete LMV341IDBVRG4. This part maintains identical electrical specifications and package configuration (SOT-23-6). The LMV341IDBVR is classified as Active product status, ensuring long-term availability and supply chain continuity. All electrical parameters, including supply voltage range (2.5 V to 5.5 V), slew rate, gain bandwidth product, and output current specifications, are identical to the original part. RoHS3 compliance and MSL Level 1 certification are maintained. Inventory availability is significantly higher (19970 units), supporting production requirements without redesign or PCB layout modifications.

LMV341MG/NOPB and LMV341MGX/NOPB (Alternative Substitutes)

These parts are functionally equivalent alternatives when package form factor can be accommodated. Both utilize the SC-70-6 package instead of SOT-23-6, requiring PCB layout modification. Electrical performance is equivalent with the exception of input bias current (0.02 pA versus 1 pA), representing improved performance. The minimum supply voltage specification is 2.7 V rather than 2.5 V; applications operating at or above 2.7 V supply voltage are fully compatible. Both parts maintain Active product status, ROHS3 compliance, and MSL Level 1 certification. LMV341MG/NOPB offers the highest inventory availability (35300 units).

Selection Criteria Summary:

• Direct replacement without redesign: LMV341IDBVR
• Alternative with package change: LMV341MG/NOPB or LMV341MGX/NOPB
• Supply voltage constraint (minimum 2.7 V required): LMV341MG/NOPB or LMV341MGX/NOPB
• Supply voltage constraint (minimum 2.5 V required): LMV341IDBVR

Frequently Asked Questions (FAQ)

Q: Can LMV341IDBVR be used as a direct replacement for LMV341IDBVRG4 without PCB modifications?

A: Yes. The LMV341IDBVR is electrically and mechanically identical to the LMV341IDBVRG4, utilizing the same SOT-23-6 package and identical pin configuration. No PCB layout changes are required.

Q: What is the difference between LMV341IDBVR and LMV341MG/NOPB?

A: The primary differences are package type and minimum supply voltage. LMV341IDBVR uses SOT-23-6 packaging with 2.5 V minimum supply voltage. LMV341MG/NOPB uses SC-70-6 packaging with 2.7 V minimum supply voltage. Input bias current is lower in LMV341MG/NOPB (0.02 pA versus 1 pA). All other electrical specifications are identical.

Q: Can LMV341MG/NOPB be used in applications designed for 2.5 V minimum supply voltage?

A: LMV341MG/NOPB is specified for 2.7 V minimum supply voltage. Applications requiring operation at 2.5 V must use LMV341IDBVR. If actual supply voltage in the application is maintained at or above 2.7 V, LMV341MG/NOPB is compatible.

Q: What is the difference between LMV341MG/NOPB and LMV341MGX/NOPB?

A: Both parts are electrically identical with identical specifications. The difference is in packaging designation and inventory availability. LMV341MG/NOPB has higher inventory (35300 units) compared to LMV341MGX/NOPB (2350 units).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. LMV341IDBVR, LMV341MG/NOPB, and LMV341MGX/NOPB are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the product status of each substitute part?

A: LMV341IDBVR, LMV341MG/NOPB, and LMV341MGX/NOPB are all classified as Active products, ensuring continued manufacturing and long-term availability from Texas Instruments.

Q: Can the SC-70-6 package parts be used on existing PCBs designed for SOT-23-6?

A: No. SC-70-6 and SOT-23-6 packages have different physical dimensions and pin layouts. PCB redesign is required to accommodate SC-70-6 packages. Direct package substitution is not possible without layout modification.
