LM258AD Equivalent & Substitute Parts

Part Overview

The LM258AD is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device integrates two independent amplifier circuits and operates across a supply voltage range of 3V to 32V. The LM258AD is classified as obsolete, which necessitates identification of active alternative components that maintain functional and electrical compatibility for new designs and production continuity.

Engineering Selection Recommendations

Primary Recommendation: Texas Instruments LM358 Series

The LM358AM/NOPB, LM358AMX/NOPB, LM358M/NOPB, and LM358MX/NOPB represent the direct active-production successors to the LM258AD. These parts maintain identical package geometry (8-SOIC, 0.154" width), supply voltage range (3V to 32V), and output current specifications (40 mA per channel). The LM358 series demonstrates enhanced gain bandwidth product (1 MHz versus 700 kHz) and maintains full ROHS3 compliance with MSL 1 rating. Packaging options include Tube (AM/M variants) and Cut Tape with Digi-Reel (AMX/MX variants). Inventory availability is substantial across all variants.

Secondary Recommendation: Diodes Incorporated AP4310 Series

The AP4310AMTR-AG1, AP4310AMTR-G1, and AP4310AUMTR-AG1 provide functional equivalence with extended operating temperature range (-40°C to 105°C). These parts feature improved input offset voltage (500 µV versus 2 mV) and reduced supply current (150 µA per channel versus 500 µA). The AP4310 series supports supply voltages up to 36V, exceeding the LM258AD specification. MSL rating varies: AP4310AMTR-AG1 and AP4310AMTR-G1 carry MSL 3, while AP4310AUMTR-AG1 carries MSL 1. High inventory availability exists for AP4310AMTR-G1 (888,300 units).

Tertiary Recommendation: Rohm Semiconductor BA10358 and BA2904 Series

The BA10358F-E1, BA10358F-E2, and BA2904F-E2 provide functional equivalence with package geometry variation (8-SOIC, 0.173" width). These parts maintain identical supply voltage range and output current specifications. The BA2904F-E2 extends operating temperature to -40°C to 125°C and reduces input bias current to 20 nA. All Rohm variants carry MSL 1 rating. Package width difference (4.40mm versus 3.90mm) requires PCB layout verification for pin-to-pin compatibility.

Compliance and Certification Status

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the LM258AD regulatory profile. ECCN classification remains EAR99 across all alternatives. HTSUS code 8542.33.0001 applies uniformly.

Frequently Asked Questions (FAQ)

Q1: Can LM358AM/NOPB directly replace LM258AD in existing PCB layouts?

A: Yes. The LM358AM/NOPB maintains identical 8-SOIC package geometry (0.154" width, 3.90mm) and pin configuration. No PCB modification is required. The part is pin-for-pin compatible.

Q2: What is the primary difference between LM358 variants (AM, AMX, M, MX)?

A: Packaging format differs. AM and M variants are supplied in Tube packaging. AMX and MX variants are supplied in Cut Tape with Digi-Reel format. Electrical specifications are identical across all four variants.

Q3: Why do Rohm BA10358 and BA2904 parts have different package widths?

A: Rohm Semiconductor uses 8-SOP package designation with 4.40mm width, compared to Texas Instruments 8-SOIC with 3.90mm width. While both are 8-pin surface mount packages, the physical width differs. PCB layout verification is required before substitution.

Q4: Is the AP4310 series suitable for applications requiring the full -25°C to 85°C temperature range of LM258AD?

A: The AP4310 series operates from -40°C to 105°C, which encompasses the LM258AD range. However, the lower operating limit (-40°C versus -25°C) and upper limit (105°C versus 85°C) represent extended specifications. For applications requiring operation only within -25°C to 85°C, the AP4310 is suitable.

Q5: What is the significance of MSL (Moisture Sensitivity Level) rating differences?

A: MSL 1 (Unlimited) indicates no moisture sensitivity restrictions; parts can be stored indefinitely without desiccant. MSL 3 (168 Hours) requires desiccant storage and limits floor-life to 168 hours after package opening. For supply chain flexibility, MSL 1 parts (LM358 series, AP4310AUMTR-AG1, Rohm series) are preferred.

Q6: Can the higher gain bandwidth product (1 MHz) of LM358 cause stability issues in LM258AD circuit designs?

A: The LM358 1 MHz bandwidth is higher than LM258AD 700 kHz specification. In stable circuit designs with adequate compensation, this difference does not introduce instability. However, circuits with marginal stability margins should be re-evaluated. Consult application circuit documentation for compensation requirements.

Q7: Which substitute part offers the lowest supply current consumption?

A: The AP4310 series (all variants) consumes 150 µA per channel, compared to LM258AD 500 µA and LM358 series 1000 µA. For battery-powered or low-power applications, AP4310 is the optimal choice.

Q8: Are there inventory or lead-time advantages to selecting one substitute family over another?

A: LM358MX/NOPB (Texas Instruments) shows highest inventory (74,281 units). AP4310AMTR-G1 (Diodes) shows substantial inventory (888,300 units). Both represent low-risk selections from supply continuity perspective. Rohm BA10358F-E2 also shows strong inventory (150,300 units).
