LM833NG Equivalent & Substitute Parts

Part Overview

The LM833NG is a 2-circuit audio amplifier integrated circuit manufactured by onsemi in 8-DIP through-hole packaging. This component is classified as obsolete, indicating it is no longer in active production. The LM833NG operates across a wide supply voltage range of 10V to 36V and is designed for audio amplification applications requiring dual-channel operation. Due to its obsolete status, equivalent substitute parts are necessary for new designs and ongoing production requirements. Active alternatives with identical or compatible electrical characteristics are available from multiple manufacturers.

Substitute Part Grouping Explanation

Substitution of the LM833NG is determined by the following critical parameters:

Primary Substitution Criteria:

Amplifier Type: Audio
Number of Circuits: 2
Package / Case: 8-DIP (0.300", 7.62mm)
Mounting Type: Through Hole
Operating Temperature Range: -40°C to 85°C

Secondary Electrical Compatibility Parameters:

Slew Rate: 7 V/µs (minimum acceptable)
Gain Bandwidth Product: 15 MHz (minimum acceptable)
Voltage - Supply Span: 10V to 36V (minimum acceptable range)
Current - Output / Channel: 29 mA (minimum acceptable)

Substitute parts are grouped into two categories:

Category 1: Direct Audio Amplifier Substitutes (Identical Amplifier Type) These parts maintain the audio amplifier classification and meet or exceed the electrical performance specifications of the LM833NG. Parts in this category include LM833DR2G (surface mount variant), LM833N/NOPB (Texas Instruments through-hole variant), RC4560IP, and MUSES8820D.

Category 2: General Purpose Amplifier Substitutes (Compatible Electrical Performance) These parts are classified as general-purpose amplifiers but provide electrical characteristics compatible with audio amplifier applications. Parts in this category include AS358P-E1, BA15218, NJM4556AD, NJM5532DD, SA5532AP, and SA5532P. These substitutes require verification of application-specific performance requirements due to differences in slew rate, gain bandwidth product, or supply voltage specifications.

Engineering Selection Recommendations

Recommended Primary Substitutes (Direct Replacements):

For applications requiring identical electrical performance and audio amplifier classification, LM833N/NOPB (Texas Instruments) is the preferred substitute. This part maintains the same amplifier type, slew rate, and gain bandwidth product as the LM833NG. It is actively manufactured, RoHS3 compliant, and available in the same 8-DIP through-hole package. The primary difference is a fixed 30V supply voltage specification compared to the LM833NG's 10V to 36V range, which may require circuit design verification for applications using supply voltages outside this range.

RC4560IP (Texas Instruments) is an alternative audio amplifier substitute with active product status and RoHS3 compliance. This part provides superior slew rate performance (5.5 V/µs) and wider supply voltage range (4V to 32V), making it suitable for applications requiring lower supply voltages. The gain bandwidth product remains at 15 MHz, matching the LM833NG specification.

Secondary Substitutes (General Purpose Amplifiers):

For applications where general-purpose amplifier performance is acceptable, SA5532AP and SA5532P (Texas Instruments) provide active product status and RoHS3 compliance. These parts offer higher slew rate (9 V/µs) and are suitable for audio applications, though they are classified as general-purpose amplifiers. Supply voltage range is 10V to 30V, which aligns with the LM833NG's minimum specification.

NJM5532DD (Nisshinbo Micro Devices Inc.) is an active general-purpose amplifier with RoHS compliance and extended supply voltage range (6V to 44V). This part provides slew rate of 8 V/µs and is suitable for applications requiring flexible supply voltage operation.

Parts Not Recommended for New Designs:

NJM4556AD carries a "Not For New Designs" product status and should not be selected for new applications despite its electrical compatibility.

Surface Mount Alternative:

LM833DR2G (onsemi) provides identical electrical specifications to the LM833NG but in 8-SOIC surface mount packaging. This part is actively manufactured and RoHS3 compliant, suitable for applications transitioning to surface mount assembly.

Frequently Asked Questions (FAQ)

Q: Can LM833N/NOPB be used as a direct replacement for LM833NG in all applications?

A: LM833N/NOPB is electrically compatible with LM833NG for most audio amplifier applications. Both parts share identical slew rate (7 V/µs) and gain bandwidth product (15 MHz). The primary difference is supply voltage specification: LM833N/NOPB operates at a fixed 30V supply, while LM833NG operates across 10V to 36V. Applications using supply voltages below 30V or above 30V require circuit design verification.

Q: What is the difference between audio amplifier and general-purpose amplifier substitutes?

A: Audio amplifiers are optimized for audio frequency applications with specifications tailored to audio signal processing. General-purpose amplifiers provide broader operational characteristics suitable for multiple application types. Substituting a general-purpose amplifier for an audio amplifier requires verification that the application's frequency response, noise characteristics, and slew rate requirements are met by the substitute part.

Q: Is LM833DR2G a suitable substitute if my circuit board uses through-hole mounting?

A: LM833DR2G is not suitable for through-hole mounting applications. This part is manufactured in 8-SOIC surface mount package and requires surface mount assembly. For through-hole applications, select from parts with 8-DIP packaging: LM833N/NOPB, RC4560IP, MUSES8820D, AS358P-E1, BA15218, NJM4556AD, NJM5532DD, SA5532AP, or SA5532P.

Q: Can I use SA5532AP in place of LM833NG for audio applications?

A: SA5532AP is electrically compatible with LM833NG for audio applications. Both parts provide 2-circuit configuration in 8-DIP through-hole packaging and operate across overlapping temperature ranges (-40°C to 85°C). SA5532AP offers higher slew rate (9 V/µs) compared to LM833NG (7 V/µs). The supply voltage range for SA5532AP is 10V to 30V, which covers the LM833NG's minimum specification but does not extend to the LM833NG's maximum of 36V. Applications using supply voltages above 30V require alternative substitutes.

Q: What is the significance of the "Not For New Designs" status on NJM4556AD?

A: "Not For New Designs" indicates that the manufacturer no longer recommends this part for new product development. While NJM4556AD may be suitable for legacy system maintenance or repair, active alternatives should be selected for new designs to ensure long-term availability and manufacturer support.

Q: Are all substitute parts RoHS compliant?

A: Most substitute parts listed are RoHS3 compliant. LM833N/NOPB, RC4560IP, AS358P-E1, BA15218, SA5532AP, and SA5532P are RoHS3 compliant. MUSES8820D and NJM5532DD are RoHS compliant. NJM4556AD is RoHS compliant. Verify specific RoHS certification requirements for your application before final part selection.

Q: What packaging options are available for LM833 equivalents?

A: The LM833 base product is available in multiple package configurations. LM833NG and LM833N/NOPB are available in 8-DIP through-hole packaging (0.300", 7.62mm). LM833DR2G is available in 8-SOIC surface mount packaging (0.154", 3.90mm width). Select packaging based on your circuit board assembly method and design requirements.

Q: How do I determine if a substitute part will work in my specific application?

A: Compare the following parameters between the LM833NG and your selected substitute: amplifier type, number of circuits, slew rate, gain bandwidth product, supply voltage range, output current per channel, and operating temperature range. Ensure the substitute part meets or exceeds the LM833NG specifications for all parameters used in your application. For general-purpose amplifier substitutes, additional verification of frequency response and noise characteristics may be required.
