Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMC6482IM/NOPB is determined by strict adherence to the following critical parameters:

Mechanical Compatibility:

• Package type: 8-SOIC surface mount with 0.154" (3.90mm) width
• Pin count and pinout configuration must match

Electrical Compatibility:

• Dual-channel amplifier configuration (2 circuits minimum)
• Rail-to-rail output capability
• Supply voltage range: minimum 3V, maximum 15.5V
• Operating temperature range: -40°C to 85°C minimum
• Output current per channel: 30 mA minimum

Regulatory & Compliance:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) preferred

Substitute parts must satisfy all mechanical and electrical parameters within the specified ranges. Parts that exceed these specifications in performance metrics (higher slew rate, higher gain bandwidth product, lower input bias current) are acceptable substitutes provided they maintain backward compatibility with the original design constraints.

Parameter Comparison

Engineering Selection Recommendations

LMC6482IMX/NOPB (Texas Instruments)

This substitute is the manufacturer-recommended equivalent. It maintains identical electrical specifications to the LMC6482IM/NOPB across all critical parameters: CMOS amplifier type, 1.3V/µs slew rate, 1.5 MHz gain bandwidth product, 0.02 pA input bias current, and 110 µV input offset voltage. The primary distinction is packaging format (Cut Tape & Digi-Reel versus Tube) and active product status. This part is suitable for direct replacement in all applications where the original LMC6482IM/NOPB was specified. Higher inventory availability (35,600 units) supports supply chain continuity.

MC33202DR2G (onsemi)

This substitute is a general-purpose amplifier that satisfies all mechanical and core electrical compatibility requirements. It provides superior performance in several metrics: higher gain bandwidth product (2.2 MHz versus 1.5 MHz), higher output current per channel (80 mA versus 30 mA), and lower supply current (0.9 mA versus 1.3 mA). However, it exhibits higher input bias current (80 nA versus 0.02 pA) and higher input offset voltage (8 mV versus 110 µV). The MC33202DR2G operates across a narrower supply voltage range (1.8V to 12V versus 3V to 15.5V) and supports an extended operating temperature range (-40°C to 105°C). Selection of this substitute requires verification that the application can tolerate the increased input offset voltage and input bias current specifications. This part is suitable for applications prioritizing higher output current capability and lower power consumption.

Both substitutes maintain RoHS3 compliance, MSL rating of 1, and 8-SOIC surface mount packaging identical to the original part.

Frequently Asked Questions (FAQ)

Q: Can LMC6482IMX/NOPB be used as a direct replacement for LMC6482IM/NOPB?

A: Yes. The LMC6482IMX/NOPB is electrically and mechanically identical to the LMC6482IM/NOPB. The only difference is packaging format: LMC6482IMX/NOPB is supplied in Cut Tape & Digi-Reel format, while LMC6482IM/NOPB is supplied in Tube format. Both parts share the same 8-SOIC package dimensions, pinout, and all electrical specifications. No circuit modifications are required.

Q: What are the key differences between LMC6482IM/NOPB and MC33202DR2G?

A: Both parts are dual-channel, rail-to-rail amplifiers in 8-SOIC packages. The LMC6482IM/NOPB is a CMOS amplifier with very low input bias current (0.02 pA) and low input offset voltage (110 µV). The MC33202DR2G is a general-purpose amplifier with higher input bias current (80 nA) and higher input offset voltage (8 mV), but offers higher output current (80 mA versus 30 mA) and higher gain bandwidth product (2.2 MHz versus 1.5 MHz). The MC33202DR2G also operates at lower supply current (0.9 mA versus 1.3 mA) but within a narrower supply voltage range (1.8V to 12V versus 3V to 15.5V).

Q: Is MC33202DR2G suitable for precision analog applications?

A: The MC33202DR2G is less suitable for precision applications requiring very low input offset voltage and input bias current. The 8 mV input offset voltage and 80 nA input bias current of the MC33202DR2G are significantly higher than the 110 µV and 0.02 pA specifications of the LMC6482IM/NOPB. Applications requiring offset voltage trimming or precision signal conditioning should retain the LMC6482IM/NOPB or LMC6482IMX/NOPB.

Q: What is the supply voltage compatibility range for each part?

A: LMC6482IM/NOPB and LMC6482IMX/NOPB both operate from 3V to 15.5V. MC33202DR2G operates from 1.8V to 12V. If your application requires supply voltages below 1.8V or above 12V, the MC33202DR2G is not suitable. If your application requires supply voltages above 12V, only the LMC6482 variants are compatible.

Q: Are all three parts RoHS3 compliant?

A: Yes. LMC6482IM/NOPB, LMC6482IMX/NOPB, and MC33202DR2G are all RoHS3 compliant with MSL rating of 1 (Unlimited). All parts meet current environmental and regulatory requirements.

Q: What is the difference between Tube and Cut Tape packaging?

A: Tube packaging (LMC6482IM/NOPB) is used for lower-volume orders and manual handling. Cut Tape & Digi-Reel packaging (LMC6482IMX/NOPB) is used for automated assembly and higher-volume production. Both formats contain identical components; the difference is in delivery and handling format. Electrical and mechanical specifications are identical.

Q: Can I use MC33202DR2G in a circuit designed for LMC6482IM/NOPB without modifications?

A: Mechanical and pinout compatibility is confirmed. However, circuit performance may be affected due to differences in input offset voltage (8 mV versus 110 µV) and input bias current (80 nA versus 0.02 pA). Applications with tight offset voltage tolerances or high-impedance input sources may require circuit redesign or offset trimming. Applications with lower precision requirements may operate without modification.

Q: Which substitute should I choose for new designs?

A: For new designs, LMC6482IMX/NOPB is recommended as the primary choice due to its active product status, identical specifications to the original part, and higher inventory availability. MC33202DR2G should be selected only if the application specifically benefits from higher output current capability, higher gain bandwidth product, or lower supply current, and can tolerate higher input offset voltage and input bias current specifications.
