LM614IWM/NOPB Equivalent & Substitute Parts

Part Overview

The LM614IWM/NOPB is a general-purpose operational amplifier integrated circuit manufactured by Texas Instruments, configured as a 4-circuit device in a 16-SOIC surface-mount package. This component is classified as obsolete, indicating it has reached end-of-life status and is no longer in active production. Due to its obsolete status, identifying functionally compatible substitute parts is essential for design continuity, production planning, and long-term system support. The availability of 893 pieces in current inventory provides limited supply for immediate requirements, necessitating the evaluation of alternative components for future applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM614IWM/NOPB is determined by strict adherence to the following electrical and mechanical compatibility criteria:

Mandatory Compatibility Parameters:

• Package type: 16-SOIC surface-mount configuration with identical 0.295" (7.50mm) width
• Number of circuits: 4 operational amplifiers per device
• Supply voltage range: Minimum 4V and maximum 36V or greater
• Operating temperature range: -40°C to 85°C or broader
• Pin configuration: Identical pinout for direct socket compatibility

Functional Performance Parameters:

• Slew rate: Equal to or greater than 0.7V/µs
• Gain bandwidth product: Equal to or greater than 800 kHz
• Input bias current: Equal to or less than 10 nA
• Input offset voltage: Equal to or less than 5 mV
• Output current per channel: Equal to or greater than 25 mA
• Supply current: Equal to or less than 450µA total

Regulatory and Compliance Parameters:

• RoHS3 compliance required
• REACH unaffected status
• ECCN classification: EAR99

The TLE2024IDW meets all mandatory compatibility criteria and exceeds several functional performance parameters, qualifying it as a direct substitute for the obsolete LM614IWM/NOPB.

Parameter Comparison

Engineering Selection Recommendations

The TLE2024IDW is the manufacturer-recommended substitute for the obsolete LM614IWM/NOPB. Both components are manufactured by Texas Instruments and share identical package geometry, pinout, and core functional classification as general-purpose operational amplifiers.

Substitution Basis:

The TLE2024IDW satisfies all mandatory mechanical and electrical compatibility requirements. The identical 16-SOIC package and surface-mount configuration enable direct board-level replacement without layout modifications. Both devices operate across the -40°C to 85°C temperature range and support the 4V to 36V supply voltage window required by the original design.

Compliance Status:

Both the LM614IWM/NOPB and TLE2024IDW maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future production. The TLE2024IDW carries an improved Moisture Sensitivity Level of 1 (unlimited storage) compared to the original part's MSL 3 (168 hours), reducing handling and storage constraints.

Performance Characteristics:

The TLE2024IDW demonstrates superior performance in several key parameters. The gain bandwidth product increases from 800 kHz to 2,800 kHz, providing enhanced frequency response capability. Input offset voltage improves from 5 mV to 1 mV, supporting higher precision applications. Output current per channel increases from 25 mA to 40 mA, enabling greater load-driving capability.

Product Status Consideration:

The LM614IWM/NOPB is classified as obsolete with limited inventory (893 pieces). The TLE2024IDW carries a Last Time Buy status, indicating a defined end-of-life timeline. For new designs or long-term production planning, component selection should account for the availability windows of both parts.

Frequently Asked Questions (FAQ)

Q: Can the TLE2024IDW be used as a direct replacement for the LM614IWM/NOPB without circuit modifications?

A: Yes. Both devices share identical 16-SOIC package geometry, pinout configuration, and supply voltage range (4V to 36V). Direct socket substitution is mechanically and electrically compatible. No PCB layout changes are required.

Q: What are the key performance differences between these two parts?

A: The TLE2024IDW provides higher gain bandwidth product (2,800 kHz vs. 800 kHz), lower input offset voltage (1 mV vs. 5 mV), and greater output current per channel (40 mA vs. 25 mA). These improvements enhance frequency response, precision, and load-driving capability. Supply current increases from 450µA to 1,050µA total.

Q: Are there any handling or storage differences between the LM614IWM/NOPB and TLE2024IDW?

A: Yes. The TLE2024IDW has a Moisture Sensitivity Level of 1 (unlimited storage), compared to the LM614IWM/NOPB's MSL 3 (168-hour limit). This means the TLE2024IDW has less stringent moisture control requirements during storage and handling.

Q: Why is the LM614IWM/NOPB classified as obsolete?

A: The LM614IWM/NOPB has reached end-of-life status and is no longer manufactured by Texas Instruments. The TLE2024IDW represents the current-generation equivalent with enhanced specifications and improved availability.

Q: What is the difference between "Obsolete" and "Last Time Buy" product status?

A: Obsolete indicates the part is no longer produced and existing inventory is depleted. Last Time Buy indicates the manufacturer has announced a final production run with a defined cutoff date, after which the part will become obsolete. The TLE2024IDW is in Last Time Buy status, providing a defined window for procurement before it transitions to obsolete.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LM614IWM/NOPB and TLE2024IDW are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can the TLE2024IDW be used in applications requiring the exact electrical characteristics of the LM614IWM/NOPB?

A: The TLE2024IDW meets or exceeds all minimum performance specifications of the LM614IWM/NOPB. Applications sensitive to specific parameter values (such as slew rate or input bias current) should verify that the TLE2024IDW's characteristics are acceptable for the intended circuit function. The improved specifications of the TLE2024IDW are generally advantageous for most general-purpose amplifier applications.
