LP358DR Equivalent & Substitute Parts

Part Overview

The LP358DR is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device contains two independent amplifier circuits and operates across a supply voltage range of 3V to 32V with an operating temperature range of 0°C to 70°C. The LP358DR is classified as an Active product and is RoHS3 compliant.

Substitute parts are necessary when the LP358DR becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for components with enhanced performance characteristics while maintaining functional compatibility within the 8-SOIC package family.

Substitute Part Grouping Explanation

Substitution logic for the LP358DR is based on strict adherence to the following critical parameters:

Critical Compatibility Parameters:

Amplifier Type: General Purpose (all substitutes must be general-purpose operational amplifiers)
Number of Circuits: 2 (dual-channel configuration required)
Package / Case: 8-SOIC or equivalent 8-pin surface mount packages (0.154" to 0.173" width acceptable)
Mounting Type: Surface Mount
Supply Voltage Range: Minimum 3V, Maximum 32V (substitute must support this range or broader)
RoHS3 Compliance: All substitutes must maintain RoHS3 compliance status

Performance Parameters (Secondary Consideration):

Voltage - Input Offset: 2 mV (substitutes may equal or exceed this specification)
Current - Output / Channel: 10 mA minimum (substitutes with 20 mA, 30 mA, or 40 mA are acceptable)
Slew Rate: 0.05 V/µs minimum (substitutes with higher slew rates are acceptable)
Gain Bandwidth Product: 100 kHz minimum (substitutes with 500 kHz, 700 kHz, or 1 MHz are acceptable)

Substitutes are grouped into two categories: Texas Instruments LM358 series variants (same base product number, different temperature grades and packaging) and alternative manufacturer equivalents (Rohm Semiconductor and onsemi) that meet all critical parameters.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Recommended for New Designs):

The LM358 series variants from Texas Instruments (LM358AM/NOPB, LM358AMX/NOPB, LM358M/NOPB, LM358MX/NOPB) are direct functional equivalents with identical package specifications and RoHS3 compliance. These parts share the same base product number and differ only in temperature grade and packaging format. All maintain the 0°C to 70°C operating temperature range of the LP358DR and support the full 3V to 32V supply voltage range. The LM358MX/NOPB variant offers the highest inventory availability (74,281 pieces) in Cut Tape format.

The LM258DR2G (onsemi) and LM2904VDR2G (onsemi) are Active-status alternatives in 8-SOIC packages with RoHS3 compliance. Both support the required supply voltage range and maintain the 2 mV input offset specification. The LM258DR2G operates at -25°C to 85°C, while the LM2904VDR2G extends to -40°C to 125°C.

The BA10358F-E2 and BA2904F-E2 (Rohm Semiconductor) are Active-status alternatives in 8-SOP packages with RoHS3 compliance. Both support the 3V to 32V supply range and maintain 2 mV input offset. The BA2904F-E2 offers extended temperature range (-40°C to 125°C) and lower input bias current (20 nA).

Secondary Substitutes (Not For New Designs):

The LM2904DR and LM2904DT are classified as "Not For New Designs" and should be used only when existing inventory constraints or legacy system requirements necessitate their use. Both maintain RoHS3 compliance and support the required supply voltage range, but their obsolescence status makes them unsuitable for new product development.

Selection Criteria:

For direct pin-compatible replacement in existing designs: Select LM358 series variants (LM358AM/NOPB, LM358AMX/NOPB, LM358M/NOPB, LM358MX/NOPB)
For extended temperature operation: Select BA2904F-E2 (-40°C to 125°C) or LM2904VDR2G (-40°C to 125°C)
For highest inventory availability: Select LM358MX/NOPB (74,281 pieces) or LM258DR2G (505,200 pieces)
For alternative manufacturer sourcing: Select BA10358F-E2 or BA2904F-E2 (Rohm) or LM258DR2G (onsemi)

All recommended substitutes maintain RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification identical to the LP358DR.

Frequently Asked Questions (FAQ)

Q: Can I use LM358 series parts as direct replacements for LP358DR?

A: Yes. The LM358AM/NOPB, LM358AMX/NOPB, LM358M/NOPB, and LM358MX/NOPB are functionally equivalent to the LP358DR. All share the same 8-SOIC package, support 3V to 32V supply voltage, maintain 2 mV input offset specification, and operate within the 0°C to 70°C temperature range. The primary differences are packaging format (Tube vs. Cut Tape) and inventory availability.

Q: What is the difference between 8-SOIC and 8-SOP packages?

A: Both are 8-pin surface mount packages with similar footprints. The 8-SOIC (Small Outline Integrated Circuit) typically has a 0.154" width, while 8-SOP (Small Outline Package) may have a 0.173" width. The BA10358F-E2 and BA2904F-E2 use 8-SOP packages with 0.173" width, which is mechanically compatible with standard 8-SOIC PCB layouts, though verification with your PCB design specifications is necessary.

Q: Can I substitute LM2904VDR2G for LP358DR?

A: Yes, with consideration of the input offset voltage specification. The LM2904VDR2G is an Active-status part in 8-SOIC package with RoHS3 compliance and supports the 3V to 32V supply range. However, its input offset voltage is specified at 7 mV, compared to 2 mV for the LP358DR. This difference is acceptable for general-purpose applications but may affect precision analog circuits requiring tight offset specifications.

Q: Why are LM2904DR and LM2904DT marked "Not For New Designs"?

A: These parts are classified as obsolete or end-of-life by their manufacturers. While they remain functionally compatible and maintain RoHS3 compliance, they should not be selected for new product development. Use these parts only when existing inventory must be consumed or when legacy system maintenance requires exact part matching.

Q: What is the impact of different slew rates on substitution?

A: The LP358DR has a slew rate of 0.05 V/µs, while substitutes range from 0.2 V/µs to unspecified values. Higher slew rates indicate faster output voltage change capability, which is beneficial for high-frequency applications. For general-purpose applications operating below 100 kHz, the slew rate difference is not critical. For applications requiring specific slew rate performance, verify the substitute's specification against your circuit requirements.

Q: Which substitute offers the best temperature range coverage?

A: The BA2904F-E2 and LM2904VDR2G both operate from -40°C to 125°C, providing the widest temperature range among all substitutes. The LP358DR operates only from 0°C to 70°C. If your application requires extended temperature operation, select BA2904F-E2 (Rohm) or LM2904VDR2G (onsemi).

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts listed maintain RoHS3 compliance status identical to the LP358DR. All are also REACH unaffected and classified as EAR99 for export control purposes.

Q: What is the difference between Cut Tape and Tube packaging?

A: Cut Tape (CT) & Digi-Reel® packaging is suitable for automated pick-and-place assembly equipment and is standard for high-volume manufacturing. Tube packaging is used for manual assembly or lower-volume applications. The functional performance of the component is identical; packaging format affects only handling and assembly process compatibility.
