Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM6211MFX is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Amplifier type classification (General Purpose)
• Number of internal circuits (1 circuit)
• Output configuration (Rail-to-Rail)
• Slew rate (5.6 V/µs)
• Gain bandwidth product (20 MHz)
• Input bias current (2 pA)
• Input offset voltage (250 µV)
• Supply current (1.05 mA)
• Output current per channel (38 mA)
• Supply voltage range (5V to 24V minimum and maximum)
• Operating temperature range (-40°C to 125°C)

Physical & Packaging Criteria:

• Package type (SC-74A, SOT-753)
• Supplier device package designation (SOT-23-5)
• Mounting technology (Surface Mount)

The LM6211MFX/NOPB qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The LM6211MFX/NOPB is the direct substitute for the obsolete LM6211MFX. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all critical parameters.

Key Differentiation Factors:

Product Status: The LM6211MFX/NOPB maintains active product status, ensuring ongoing availability and manufacturer support. The original LM6211MFX is obsolete and subject to supply discontinuation.

Regulatory Compliance: The LM6211MFX/NOPB is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The LM6211MFX is RoHS non-compliant and does not satisfy modern procurement standards for many applications and regions.

Supply Availability: Current inventory of LM6211MFX/NOPB (3,100 units) supports ongoing procurement. The LM6211MFX, while currently in stock (8,800 units), represents a declining resource as the product reaches end-of-life.

For new designs and redesigns of existing applications, the LM6211MFX/NOPB is the appropriate selection. For legacy systems currently using the LM6211MFX, direct substitution with LM6211MFX/NOPB is electrically and mechanically compatible without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the LM6211MFX/NOPB be used as a direct replacement for the LM6211MFX in existing designs?

A: Yes. The LM6211MFX/NOPB is electrically and mechanically identical to the LM6211MFX. All electrical parameters, package dimensions, and pin configurations are equivalent. No circuit modifications are required.

Q: What is the difference between LM6211MFX and LM6211MFX/NOPB?

A: The primary differences are product status and regulatory compliance. The LM6211MFX/NOPB is an active product with ROHS3 compliance, while the LM6211MFX is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Why is the LM6211MFX marked as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, technology evolution, and production decisions. The LM6211MFX has been superseded by the LM6211MFX/NOPB variant, which maintains full compatibility while meeting current regulatory requirements.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the SOT-23-5 package (SC-74A, SOT-753 case designation) with identical pinout and mechanical dimensions. They are pin-for-pin compatible.

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

A: The "/NOPB" suffix indicates "No Plumbum" (lead-free) construction, reflecting RoHS compliance. This is a manufacturing and material specification that does not affect electrical performance or functionality.

Q: Can I use the LM6211MFX/NOPB in applications originally designed for the LM6211MFX?

A: Yes. Complete electrical and mechanical equivalence ensures direct substitution. The LM6211MFX/NOPB is suitable for all applications previously supported by the LM6211MFX.

Q: What supply voltage range does this operational amplifier support?

A: Both the LM6211MFX and LM6211MFX/NOPB operate across a 5V to 24V supply range, supporting single or dual supply configurations within this specification.

Q: Is the LM6211MFX/NOPB suitable for new product designs?

A: Yes. The LM6211MFX/NOPB is the recommended choice for new designs. It carries active product status, ROHS3 compliance, and assured long-term availability from Texas Instruments.
