LM358PW-JF Equivalent & Substitute Parts

Part Overview

The LM358PW-JF is a general-purpose operational amplifier featuring two independent circuits in a push-pull output configuration. Manufactured by Texas Instruments, this device is classified as a Last Time Buy component, indicating discontinued production with limited availability. The part is housed in an 8-TSSOP surface-mount package and is qualified to AEC-Q100 automotive standards. Due to its Last Time Buy status and limited inventory (725 pieces), identification of functionally equivalent substitute components is necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM358PW-JF is determined by equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 2
• Package / Case: 8-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Slew Rate: 0.3 V/µs
• Gain Bandwidth Product: 700 kHz
• Current - Input Bias: 20 nA
• Voltage - Supply Span (Min): 3 V or lower
• Voltage - Supply Span (Max): 30 V or higher
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The LM358PWR, manufactured by Rohm Semiconductor, meets all functional equivalence criteria. While certain electrical parameters differ (Input Offset Voltage, Supply Current, Output Current, Operating Temperature Range), these variations remain within acceptable substitution tolerances for general-purpose amplifier applications. The substitute maintains identical package geometry, pin configuration, and core operational specifications.

LM358PWR Substitution Assessment:

The LM358PWR is a direct functional substitute for the LM358PW-JF based on package compatibility, core electrical specifications, and compliance certifications. Both devices are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental performance.

The LM358PWR offers superior electrical characteristics in specific parameters: Input Offset Voltage is reduced to 1 mV (compared to 3 mV), Output Current per Channel is increased to 40 mA (compared to 30 mA), and the operating temperature range is extended to -40°C to 85°C (compared to 0°C to 70°C). These improvements provide enhanced performance margins without introducing compatibility issues.

The substitute part carries a "Not For New Designs" status, indicating mature product lifecycle. However, this designation does not preclude its use as a replacement component in existing applications. The LM358PWR maintains significantly higher inventory availability (105,300 pieces) compared to the main part (725 pieces), supporting production continuity.

Pin-to-pin compatibility and identical 8-TSSOP package geometry ensure direct PCB-level substitution without layout modifications. No circuit redesign is required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can the LM358PWR be used as a direct replacement for the LM358PW-JF without circuit modifications?

A: Yes. Both devices share identical package geometry (8-TSSOP), pin configuration, and core operational specifications (Slew Rate, Gain Bandwidth Product, Input Bias Current, Supply Voltage Range). Direct PCB-level substitution is supported without circuit redesign.

Q: What are the key electrical differences between these parts?

A: The LM358PWR exhibits lower Input Offset Voltage (1 mV vs. 3 mV), higher Output Current capability (40 mA vs. 30 mA per channel), and extended operating temperature range (-40°C to 85°C vs. 0°C to 70°C). Supply current is slightly higher at 600 µA versus 500 µA per channel. These differences represent performance improvements rather than incompatibilities.

Q: Are both parts automotive-qualified?

A: The LM358PW-JF carries AEC-Q100 automotive qualification. The LM358PWR specifications provided do not include explicit automotive qualification designation. Automotive application requirements should be evaluated against the substitute part's qualification status.

Q: What is the significance of the "Last Time Buy" and "Not For New Designs" designations?

A: "Last Time Buy" indicates the LM358PW-JF is discontinued with limited remaining inventory. "Not For New Designs" indicates the LM358PWR is in mature lifecycle phase. Both designations reflect product maturity rather than technical deficiency. The LM358PWR remains available in production quantities suitable for replacement applications.

Q: Are there any moisture sensitivity or environmental compliance concerns with substitution?

A: Both parts are rated MSL 1 (Unlimited) and ROHS3 compliant, ensuring equivalent environmental performance and handling requirements. No additional moisture sensitivity or compliance considerations apply to substitution.

Q: Does the LM358PWR support the same supply voltage range?

A: The LM358PWR supports a slightly extended supply voltage range (3 V to 32 V) compared to the LM358PW-JF (3 V to 30 V). This represents a performance enhancement and does not restrict substitution in applications using the original 3 V to 30 V range.
