LMC6041IN Equivalent & Substitute Parts

Part Overview

The LMC6041IN is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-DIP through-hole package. This device features rail-to-rail output capability and is designed for low-power applications requiring single-circuit amplification. The LMC6041IN is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMC6041IN is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters:

• Amplifier type (General Purpose)
• Number of circuits (1)
• Output type (Rail-to-Rail)
• Slew rate (0.02 V/µs)
• Gain bandwidth product (75 kHz)
• Input bias current (0.002 pA)
• Input offset voltage (1 mV)
• Supply current (18 µA)
• Output current per channel (40 mA)
• Supply voltage range (4.5 V to 15.5 V)
• Operating temperature range (-40°C to 85°C)

Mechanical Parameters:

• Mounting type (Through Hole)
• Package type (8-DIP with 0.300" / 7.62mm pitch)

The LMC6041IN/NOPB is identified as a direct substitute based on identical electrical specifications and mechanical compatibility. Packaging differences (Tube versus standard) and product status variations do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The LMC6041IN/NOPB serves as the direct substitute for the obsolete LMC6041IN. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility in existing circuit designs.

Product Status Consideration: The LMC6041IN is classified as obsolete, while the LMC6041IN/NOPB carries a Last Time Buy status. This distinction indicates that the LMC6041IN/NOPB represents the final production run available from the manufacturer and should be prioritized for procurement when component replacement or design refresh is required.

Compliance Difference: The LMC6041IN/NOPB is ROHS3 compliant, whereas the original LMC6041IN is RoHS non-compliant. This compliance upgrade in the substitute part aligns with current regulatory requirements for electronic components in many markets and applications.

Packaging: The LMC6041IN/NOPB is supplied in Tube packaging, which may differ from the original part's packaging format. Both maintain the same 8-DIP through-hole package configuration and are mechanically interchangeable on printed circuit boards.

Frequently Asked Questions (FAQ)

Q: Can the LMC6041IN/NOPB be used as a direct replacement for the LMC6041IN?

A: Yes. The LMC6041IN/NOPB is electrically and mechanically identical to the LMC6041IN across all specified parameters. Both components feature the same amplifier type, output characteristics, supply requirements, and 8-DIP through-hole package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between LMC6041IN and LMC6041IN/NOPB?

A: The primary differences are product status and RoHS compliance. The LMC6041IN is obsolete and RoHS non-compliant, while the LMC6041IN/NOPB is Last Time Buy and ROHS3 compliant. Electrical and mechanical specifications are identical. The /NOPB designation indicates lead-free (no-lead) processing.

Q: Are there any pin configuration differences between these parts?

A: No. Both the LMC6041IN and LMC6041IN/NOPB use the 8-DIP package with 0.300" (7.62mm) pitch. Pin assignments and functionality are identical, enabling direct board-level substitution.

Q: What does Last Time Buy status mean for the LMC6041IN/NOPB?

A: Last Time Buy indicates that the LMC6041IN/NOPB represents the final production run from Texas Instruments. After this inventory is exhausted, the component will no longer be manufactured. Procurement planning should account for this status when sourcing components for long-term production requirements.

Q: Can the LMC6041IN/NOPB operate within the same temperature range as the LMC6041IN?

A: Yes. Both components operate across the identical temperature range of -40°C to 85°C, ensuring thermal compatibility in equivalent applications.

Q: Does the RoHS3 compliance of LMC6041IN/NOPB affect circuit performance?

A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical performance. The LMC6041IN/NOPB maintains identical electrical characteristics and performance specifications as the LMC6041IN.

Q: What is the supply voltage requirement for these components?

A: Both the LMC6041IN and LMC6041IN/NOPB require a supply voltage between 4.5 V and 15.5 V, with a typical supply current of 18 µA per circuit.
