Engineering Selection Recommendations

Tier 1 - Recommended Direct Replacement:

LM258ADR (Texas Instruments) is the primary recommended substitute. This part maintains identical electrical specifications to the LM258ADRG4 across all critical parameters: 0.3 V/µs slew rate, 700 kHz gain bandwidth product, 15 nA input bias current, and 500 µA supply current per channel. The LM258ADR is in active production status with 27,600 units in stock, ensuring long-term availability. Both parts share the 8-SOIC package with 3.90mm width and identical pinout, enabling direct board-level substitution without design modification.

Tier 2 - Enhanced Performance Alternatives:

LM258ADT (STMicroelectronics) provides superior electrical performance with 0.6 V/µs slew rate, 1.1 MHz gain bandwidth product, and lower input offset voltage (1 mV). This part qualifies for automotive applications under AEC-Q100 standard and operates across -40°C to 105°C, extending the temperature range beyond the original specification. The 8-SOIC package is identical. This option is suitable for designs requiring enhanced performance margins or automotive-grade reliability.

A: LM258ADT (STMicroelectronics) provides the most significant performance enhancement with 0.6 V/µs slew rate (double the original), 1.1 MHz gain bandwidth product (57% higher), and lower input offset voltage (1 mV versus 2 mV). This part maintains the 8-SOIC package and 40 mA output current while extending the operating temperature range to -40°C to 105°C. AEC-Q100 automotive qualification is included.

Q: What is the supply availability status of substitute parts?

A: LM258DR2G (onsemi) has the highest inventory with 505,200 units in stock. LM358MX/NOPB (Texas Instruments) has 74,281 units. BA10358F-E2 (Rohm Semiconductor) has 150,300 units. LM258ADT (STMicroelectronics) has 60,400 units. LM258ADR (Texas Instruments) has 27,600 units. All recommended substitutes are in active production with substantial inventory levels.

Q: Can LM258ADRG4 be used in automotive applications?

A: The LM258ADRG4 itself does not carry automotive qualification. For automotive applications, LM258ADT (STMicroelectronics) is the appropriate choice, as it qualifies under AEC-Q100 standard and operates across -40°C to 105°C.

Q: What packaging options are available for substitutes?

A: All Texas Instruments substitutes (LM258ADR, LM358 series, LM258ADT) are available in 8-SOIC surface mount package matching the original. Rohm alternatives (BA10358F-E2, BA2904F-E2) are supplied in 8-SOP package with slightly different dimensions. onsemi LM258DR2G is supplied in 8-SOIC package.
