Substitute Part Grouping Explanation
Substitute parts for the LM833DR2 are grouped into two categories based on functional equivalence and application suitability:
Direct Equivalents (Same Base Product Number)
Direct equivalents share the LM833 base product number and maintain identical electrical specifications across all critical audio amplifier parameters: 15 MHz gain bandwidth product, 7 V/µs slew rate, 300 nA input bias current, and 300 µV input offset voltage. These parts differ only in packaging format (Cut Tape versus Tape & Reel) or manufacturer source. Direct equivalents include LM833DR2G, LM833DT, LM833M, LM833M/NOPB, and LM833MX/NOPB.
Functional Alternatives (Different Base Product Number)
Functional alternatives are general-purpose or audio-grade amplifiers that operate within the same 8-SOIC package and support the full supply voltage range of the LM833DR2 (10 V to 36 V minimum/maximum). These parts maintain compatibility with the mechanical package footprint and thermal operating range (-40°C to 85°C) but may exhibit variations in slew rate, gain bandwidth product, input bias current, or output current per channel. Functional alternatives include AS358MTR-E1, AS358MTR-G1, BA4560FJ-GE2, and LME49723MAX/NOPB.
Key Parameters Determining Substitution:

The only difference is packaging format (Tape & Reel versus Cut Tape). Both use the same 8-SOIC package footprint and pinout. LM833DR2G is active and ROHS3 compliant.
Q: What is the difference between LM833M and LM833M/NOPB?
A: LM833M and LM833M/NOPB are functionally equivalent variants of the LM833 base product from different manufacturers (National Semiconductor and Texas Instruments, respectively). Both maintain 15 MHz gain bandwidth product and 7 V/µs slew rate. LM833M/NOPB is ROHS3 compliant; RoHS status for LM833M is not specified. The "/NOPB" suffix indicates "No Plumbum" (lead-free) construction. Electrical performance is identical.
Q: Can AS358MTR-E1 or AS358MTR-G1 replace LM833DR2 in audio applications?
A: AS358MTR-E1 and AS358MTR-G1 are general-purpose amplifiers, not audio-grade devices. While they share the 8-SOIC package and -40°C to 85°C operating range, they exhibit significantly different electrical characteristics: input offset voltage of 2 mV (versus 300 µV), no specified slew rate or gain bandwidth product, and much lower supply current (0.7 mA per channel versus 4 mA). These parts are suitable for general-purpose signal conditioning but not recommended for audio applications requiring low noise and stable gain characteristics.
Q: What are the advantages of LME49723MAX/NOPB over LM833DR2?
A: LME49723MAX/NOPB provides enhanced audio performance specifications: 19 MHz gain bandwidth product (versus 15 MHz), 8 V/µs slew rate (versus 7 V/µs), and lower input bias current of 200 nA (versus 300 nA). These improvements result in wider bandwidth, faster transient response, and reduced input noise current. The trade-off is slightly higher supply current (6.7 mA per channel versus 4 mA) and lower maximum output current (25 mA versus 29 mA). This part is recommended for high-fidelity audio designs where improved frequency response is required.
Q: Are there packaging format differences between substitute parts?
A: Yes. LM833DR2 is supplied in Cut Tape (CT) format. LM833DR2G is Tape & Reel (TR). LM833DT is Cut Tape & Digi-Reel. LM833M/NOPB is Tube. LM833MX/NOPB is Cut Tape & Digi-Reel. LME49723MAX/NOPB is Cut Tape & Digi-Reel. AS358MTR-E1 is Cut Tape & Digi-Reel. AS358MTR-G1 is Tape & Reel. All parts use the same 8-SOIC (0.154", 3.90mm Width) package footprint and are compatible with standard surface mount assembly processes. Packaging format selection depends on production volume and handling requirements.
Q: What is the minimum supply voltage for each substitute part?
A: LM833DR2 requires minimum 10 V supply. LM833DR2G, LM833M, and LM833M/NOPB also require 10 V minimum. LM833DT operates at 5 V minimum. LME49723MAX/NOPB operates at 5 V minimum. BA4560FJ-GE2 requires 8 V minimum. AS358MTR-E1 and AS358MTR-G1 operate at 3 V minimum. For designs using the LM833DR2 with 10 V or higher supply voltage, all listed substitutes are compatible.
