LM10CWM Equivalent & Substitute Parts

Part Overview

The LM10CWM is a general-purpose operational amplifier manufactured by Texas Instruments, housed in a 14-SOIC surface mount package. This device is classified as a Last Time Buy product, indicating discontinued production with limited remaining inventory. The LM10CWM serves applications requiring low input bias current and wide supply voltage range operation. Identifying equivalent substitute parts is necessary due to the Last Time Buy status and to ensure long-term design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitute parts for the LM10CWM are qualified based on electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Equivalence Requirements:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Current - Input Bias: 12 nA
• Voltage - Input Offset: 500 µV
• Current - Supply: 300 µA
• Current - Output / Channel: 20 mA
• Voltage - Supply Span (Min): 1.1 V
• Voltage - Supply Span (Max): 40 V
• Operating Temperature: 0°C to 70°C

Mechanical Equivalence Requirements:

• Package / Case: 14-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 14-SOIC

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

All identified substitute parts meet these criteria and are manufactured by Texas Instruments under the LM10 base product number series.

Parameter Comparison

Engineering Selection Recommendations

LM10CWM/NOPB is a direct electrical and mechanical equivalent with Active product status. This part is supplied in Tube packaging and represents the primary substitute for the Last Time Buy LM10CWM. The /NOPB suffix indicates lead-free plating compliance. Moisture Sensitivity Level is rated at 3 (168 Hours), compared to the original part's 2A (4 Weeks) rating.

LM10CWMX/NOPB is the manufacturer-recommended substitute, also with Active product status. This part is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The /NOPB suffix indicates lead-free plating compliance. Moisture Sensitivity Level is rated at 3 (168 Hours). The "X" designation in the part number indicates extended temperature or performance characteristics within the specified operating range.

Both substitute parts maintain full electrical equivalence with the original LM10CWM across all specified parameters. Selection between LM10CWM/NOPB and LM10CWMX/NOPB depends on packaging requirements: Tube packaging for manual handling or small-volume applications, or Tape & Reel packaging for high-volume automated assembly.

Frequently Asked Questions (FAQ)

Q: Can LM10CWM/NOPB be used as a direct replacement for LM10CWM?

A: Yes. LM10CWM/NOPB is electrically and mechanically equivalent to LM10CWM. Both devices share identical electrical specifications including input bias current, input offset voltage, supply current, output current, and supply voltage range. Both are housed in 14-SOIC surface mount packages and operate across the same temperature range (0°C to 70°C). The primary difference is product status: LM10CWM/NOPB is Active, while LM10CWM is Last Time Buy.

Q: What is the difference between LM10CWM/NOPB and LM10CWMX/NOPB?

A: Both parts are electrically equivalent with identical electrical specifications. The primary differences are packaging format and the "X" designation. LM10CWM/NOPB is supplied in Tube packaging, while LM10CWMX/NOPB is supplied in Tape & Reel (TR) packaging. The "X" in the part number indicates a variant within the LM10 series. Both are Active products manufactured by Texas Instruments.

Q: What does the /NOPB suffix mean?

A: The /NOPB suffix indicates that the part is manufactured with lead-free plating and is compliant with RoHS3 regulations. This suffix is standard for modern electronic components and does not affect electrical performance or compatibility.

Q: Are there packaging considerations when substituting these parts?

A: Yes. LM10CWM/NOPB is supplied in Tube packaging, suitable for manual component handling and small-volume applications. LM10CWMX/NOPB is supplied in Tape & Reel (TR) packaging, optimized for automated pick-and-place assembly equipment. Select the packaging format based on your assembly process requirements.

Q: What is the Moisture Sensitivity Level difference between these parts?

A: The original LM10CWM has MSL 2A (4 Weeks), while both substitute parts LM10CWM/NOPB and LM10CWMX/NOPB have MSL 3 (168 Hours). MSL 3 indicates the component can be stored in dry conditions for up to 168 hours before soldering. This difference requires appropriate moisture control during storage and handling but does not affect electrical performance or long-term reliability when proper moisture management procedures are followed.

Q: Why is LM10CWM classified as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific part number variant. Existing inventory is available for purchase, but no future production is planned. This classification makes identifying active substitute parts essential for ensuring continued supply chain availability and design continuity.

Q: Can I mix LM10CWM/NOPB and LM10CWMX/NOPB in the same design?

A: Yes. Both parts are electrically equivalent and can be used interchangeably within the same circuit design. The choice between them depends on your assembly process and packaging requirements, not on electrical compatibility.
