LM10CWMX Equivalent & Substitute Parts

Part Overview

The LM10CWMX is a general-purpose operational amplifier manufactured by Texas Instruments, housed in a 14-SOIC surface mount package. This device is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and procurement. The LM10CWMX delivers a single amplifier circuit suitable for general-purpose analog signal processing applications with a wide supply voltage range of 1.1 V to 40 V and low input bias current of 12 nA.

Substitute Part Grouping Explanation

Substitution of the LM10CWMX is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• 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: 1.1 V to 40 V
• Operating Temperature Range: 0°C to 70°C
• Package / Case: 14-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

The LM10CWMX/NOPB qualifies as a direct substitute because it maintains identical electrical specifications and mechanical packaging while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The LM10CWMX/NOPB is the direct functional equivalent of the LM10CWMX. Both components share identical electrical performance specifications and mechanical packaging. The primary distinction lies in product lifecycle status and regulatory compliance:

LM10CWMX/NOPB Advantages:

• Active product status ensures continued manufacturer support and availability
• ROHS3 compliant, meeting current environmental and regulatory requirements
• Tape & Reel packaging format supports automated assembly processes
• Improved moisture sensitivity level (MSL 3, 168 Hours) compared to MSL 2A (4 Weeks)

For new designs or production requiring long-term component availability and regulatory compliance, the LM10CWMX/NOPB is the appropriate selection. The electrical and mechanical compatibility ensures direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the LM10CWMX/NOPB replace the LM10CWMX in existing designs?

A: Yes. The LM10CWMX/NOPB maintains identical electrical specifications and 14-SOIC package dimensions. Direct substitution is supported without circuit modification.

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

A: The primary differences are product status (Obsolete vs. Active), RoHS compliance (non-compliant vs. ROHS3 Compliant), and packaging format (Tube vs. Tape & Reel). Electrical performance and pinout are identical.

Q: Is the 14-SOIC package compatible with existing PCB layouts?

A: Yes. Both the LM10CWMX and LM10CWMX/NOPB use the same 14-SOIC (0.295", 7.50mm Width) surface mount package. PCB footprints and assembly processes remain unchanged.

Q: What is the significance of the /NOPB designation?

A: The /NOPB suffix indicates "No Plumbum" (lead-free), confirming RoHS3 compliance and the absence of lead in the component composition.

Q: Are there inventory considerations when selecting between these parts?

A: The LM10CWMX/NOPB has higher current inventory availability (5150 Pcs) compared to the LM10CWMX (2223 Pcs), supporting consistent procurement for production requirements.
