MCP6482T-E/SN Equivalent & Substitute Parts
Part Overview
The MCP6482T-E/SN is a general-purpose operational amplifier manufactured by Microchip Technology, configured as a dual-channel (2 circuit) rail-to-rail amplifier in an 8-SOIC surface-mount package. This device is actively produced and widely used in analog signal conditioning, filtering, and amplification applications requiring low-power operation across supply voltages from 2.2 V to 5.5 V.
Substitute parts are identified when design requirements change, original part availability becomes limited, or alternative sourcing strategies are implemented. Equivalent devices must maintain functional compatibility through matching package type, pin configuration, electrical performance envelope, and operating temperature range.

Substitute Part Grouping Explanation
Substitution eligibility for the MCP6482T-E/SN is determined by the following mandatory criteria:
Package Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface-mount package to ensure direct PCB footprint compatibility without layout redesign.
Electrical Performance Envelope: Substitute parts must operate within the supply voltage range of 2.2 V to 5.5 V. The MCP6482T-E/SN operates across the full industrial temperature range of -40°C to 125°C; substitutes operating at reduced temperature ranges (-40°C to 85°C) are acceptable for applications not requiring the extended upper temperature limit.
Functional Configuration: All substitutes must be dual-channel (2 circuit) rail-to-rail amplifiers to maintain pin-for-pin compatibility and circuit behavior.
Regulatory Compliance: All substitute parts must maintain ROHS3 compliance and MSL rating of 1 (Unlimited) to ensure manufacturing process compatibility and shelf-life requirements.
The following substitute parts meet these criteria and are grouped by manufacturer and packaging configuration.

Engineering Selection Recommendations
Full Temperature Range Requirement (-40°C to 125°C):
When applications require operation across the complete industrial temperature range supported by the MCP6482T-E/SN, the following substitutes maintain this specification:
AD8602ARZ, AD8602ARZ-REEL, AD8602ARZ-REEL7, and AD8602WARZ-R7 (all Analog Devices Inc. CMOS variants) are direct functional equivalents with enhanced electrical performance. These devices feature higher slew rate (6 V/µs vs. 2.7 V/µs), superior gain-bandwidth product (8.4 MHz vs. 4 MHz), and lower input offset voltage (80 µV vs. 1.5 mV). The AD8602 series operates across -40°C to 125°C and maintains ROHS3 compliance and MSL 1 rating. Selection among AD8602 variants depends on packaging requirements: AD8602ARZ (Tube), AD8602ARZ-REEL (Tape & Reel), AD8602ARZ-REEL7 (Cut Tape & Digi-Reel), and AD8602WARZ-R7 (Cut Tape & Digi-Reel).
LMV822IDT (STMicroelectronics) is qualified to AEC-Q100 automotive standards and operates across -40°C to 125°C. This device provides comparable slew rate (1.9 V/µs) and higher gain-bandwidth product (5.5 MHz). It is supplied in Cut Tape & Digi-Reel packaging and maintains ROHS3 compliance.
Reduced Temperature Range Applications (-40°C to 85°C):
When applications do not require operation above 85°C, the following substitutes are acceptable:
LMR932F-GE2 (Rohm Semiconductor) operates from -40°C to 85°C with lower power consumption (140 µA supply current) but reduced slew rate (0.35 V/µs) and gain-bandwidth product (1.4 MHz). This device is suitable for low-speed, power-constrained applications.
LMV822M, LMV822M/NOPB, and LMV822MX/NOPB (Texas Instruments LMV® series) operate from -40°C to 85°C. LMV822M is listed as Last Time Buy; LMV822M/NOPB (Tube) and LMV822MX/NOPB (Cut Tape & Digi-Reel) are Active status. These devices provide slew rate of 2 V/µs and gain-bandwidth product of 5.6 MHz with higher supply current (500 µA).
MAX4282ESA+ (Analog Devices Inc./Maxim Integrated GainAmp™ series) operates from -40°C to 85°C with lower slew rate (0.7 V/µs) and gain-bandwidth product (2 MHz), suitable for precision, low-speed applications. Supplied in Tube packaging.
Packaging Considerations:
All substitute parts are available in 8-SOIC (0.154", 3.90mm Width) package format. Packaging variants (Tube, Tape & Reel, Cut Tape & Digi-Reel) do not affect electrical compatibility but influence procurement and assembly processes. The original MCP6482T-E/SN is supplied in Tape & Reel format; equivalent packaging options are available across all substitute families.
Product Status:
The MCP6482T-E/SN maintains Active product status with 12,600 units in stock. All recommended substitutes are Active status except LMV822M (Last Time Buy). For long-term design stability, prioritize Active status parts.
Frequently Asked Questions (FAQ)
Q: Can I directly replace MCP6482T-E/SN with any of these substitute parts without PCB modification?
A: Yes, all listed substitute parts use the identical 8-SOIC (0.154", 3.90mm Width) package and maintain pin-for-pin compatibility. No PCB layout changes are required. However, electrical performance differences (slew rate, gain-bandwidth product, supply current) may affect circuit behavior; circuit simulation or bench testing is recommended for critical applications.
Q: What is the key difference between the AD8602 variants (ARZ, ARZ-REEL, ARZ-REEL7, WARZ-R7)?
A: All AD8602 variants share identical electrical specifications. The differences are packaging and distribution format: ARZ (Tube), ARZ-REEL (Tape & Reel), ARZ-REEL7 (Cut Tape & Digi-Reel), and WARZ-R7 (Cut Tape & Digi-Reel). Selection depends on procurement and assembly requirements, not electrical performance.
Q: Why do some substitutes have higher supply current than the MCP6482T-E/SN?
A: The AD8602 series (750 µA) and LMV822 series (500 µA) consume more power than the MCP6482T-E/SN (240 µA) but deliver higher performance metrics (slew rate, gain-bandwidth product, output current capability). This represents a performance-versus-power trade-off. For power-constrained applications, the LMR932F-GE2 (140 µA) is the lowest-power option.
Q: Can I use LMV822M or LMV822M/NOPB if my application requires operation at 125°C?
A: No. LMV822M and LMV822M/NOPB are rated only to 85°C maximum operating temperature. For 125°C operation, use AD8602 variants, AD8602ARZ-REEL7, or LMV822IDT.
Q: What does "Last Time Buy" status mean for LMV822M?
A: Last Time Buy indicates that Texas Instruments has announced end-of-life for this part. Existing inventory may be available, but production will cease. For new designs or long-term production, select Active status alternatives such as LMV822M/NOPB or LMV822MX/NOPB.
Q: Are all these parts RoHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with modern manufacturing processes and shelf-life requirements.
Q: Which substitute offers the best overall performance improvement over MCP6482T-E/SN?
A: The AD8602 series (all variants) provides the most significant performance enhancement: 2.2× higher slew rate (6 V/µs vs. 2.7 V/µs), 2.1× higher gain-bandwidth product (8.4 MHz vs. 4 MHz), and 18.75× lower input offset voltage (80 µV vs. 1.5 mV). These improvements are offset by higher supply current (750 µA vs. 240 µA).
Q: Can I mix packaging formats in a single production run?
A: Yes. All substitute parts maintain identical electrical specifications within each manufacturer family. Mixing Tube, Tape & Reel, and Cut Tape & Digi-Reel formats does not affect circuit performance but may require separate procurement and assembly handling procedures.
