LM324DR-M Equivalent & Substitute Parts Reference

Part Overview

The Texas Instruments LM324DR-M is a general-purpose linear amplifier featuring 4 circuits with push-pull output in a 14-SOIC (0.154", 3.90mm width) surface-mount package. The product status is "Last Time Buy," indicating the lifecycle is ending, which may necessitate identifying alternative models for continued production or inventory risk mitigation. The amplifier is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) rating of 1 (unlimited).

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching parameters critical for the function, footprint, and compliance of general-purpose linear amplifiers in the Linear, Amplifiers product category. The following key parameters serve as the basis for grouping substitute parts:

• Amplifier Type
• Number of Circuits
• Gain Bandwidth Product
• Slew Rate
• Input Bias Current
• Input Offset Voltage
• Supply Current
• Output Current per Channel
• Supply Voltage Range
• Operating Temperature
• Package / Case and Mounting Type
• RoHS Compliance
• Moisture Sensitivity Level (MSL)

Only parts that match or closely align with these parameters are considered acceptable substitutes.

Parameter Comparison

Engineering Selection Recommendations

For ongoing designs and inventory management, product status and compliance parameters are critical. The Texas Instruments LM324DR-M is in "Last Time Buy" status, indicating limited future availability. The Rohm Semiconductor LM324DR is designated as "Obsolete." Both parts are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), meeting common compliance and processing requirements.

Selection should be based on current availability, compliance certifications, and matching electrical and mechanical specifications as provided.

Frequently Asked Questions (FAQ)

Q1: What qualifies a linear amplifier like the LM324DR-M for substitution?
A1: Qualification requires matching amplifier type, number of circuits, gain bandwidth product, slew rate, input bias current, input offset voltage, supply current, output current per channel, supply voltage range, package/case, RoHS status, and MSL.

Q2: Does package compatibility affect substitution of LM324DR-M?
A2: Yes, both the main part and substitutes must use the same 14-SOIC (0.154", 3.90mm width) surface-mount package to ensure mechanical and assembly compatibility.

Q3: Is there any functional difference between Texas Instruments LM324DR-M and Rohm Semiconductor LM324DR?
A3: Both are general purpose amplifiers with 4 circuits and nearly identical key parameters. Any minor differences are listed in the parameter comparison table.

Q4: What compliance requirements must substitute parts for LM324DR-M meet?
A4: Substitute parts must be ROHS3 compliant and meet the same or lower Moisture Sensitivity Level (MSL 1).

Q5: Can obsolete parts be used as direct substitutes?
A5: Only product status and compliance parameters provided are considered. If substitute parts are marked as obsolete, product lifecycle considerations must be addressed during selection.
