MCP604T-I/SL CMOS Amplifier Equivalent & Substitute Parts

Part Overview

The MCP604T-I/SL is a CMOS operational amplifier manufactured by Microchip Technology, configured as a 4-circuit rail-to-rail amplifier in a 14-SOIC surface mount package. This device is classified as Active product status and is ROHS3 compliant. The MCP604T-I/SL is supplied in Cut Tape (CT) & Digi-Reel® packaging with 20,900 units currently in stock.

Substitute parts are necessary when the original MCP604T-I/SL becomes unavailable, when alternative packaging formats are required, or when design specifications permit operation with equivalent electrical characteristics. Equivalent devices must maintain compatibility across critical parameters including package type, pin configuration, supply voltage range, and output drive capability.

Engineering Selection Recommendations

Direct Substitute (Identical Specifications):

MCP604-I/SL is a direct substitute for MCP604T-I/SL. Both devices are manufactured by Microchip Technology with identical electrical characteristics, supply voltage range, and operating temperature specifications. The primary difference is packaging format: MCP604-I/SL is supplied in Tube packaging versus Cut Tape (CT) & Digi-Reel® for the MCP604T-I/SL. Both maintain ROHS3 compliance and MSL 1 rating. Selection between these two depends solely on packaging and handling requirements for production processes.

Functional Equivalents with Enhanced Performance:

AD8694ARZ and AD8694ARZ-REEL7 (Analog Devices) provide superior performance characteristics including higher slew rate (5 V/µs versus 2.3 V/µs), higher gain bandwidth product (10 MHz versus 2.8 MHz), and greater output current per channel (80 mA versus 22 mA). Both devices maintain the same supply voltage range (2.7 V to 6 V) and operating temperature range (-40°C to 125°C). These substitutes are suitable for applications requiring higher bandwidth and faster transient response. Both are Active status and ROHS3 compliant. AD8694ARZ-REEL7 is supplied in Cut Tape (CT) & Digi-Reel® packaging with significantly higher inventory (36,253 units).

Functional Equivalents with Lower Performance:

LMV324 series devices (Texas Instruments and UMW) operate with lower slew rate (1 V/µs) and lower gain bandwidth product (1 MHz). These devices are suitable for applications where the MCP604T-I/SL performance exceeds design requirements. LMV324MX/NOPB and LMV324M/NOPB offer higher output current per channel (160 mA) and extended operating temperature range (-40°C to 125°C). LMV324ID is designated Last Time Buy status and should be avoided for new designs. LMV324Q1MAX/NOPB includes AEC-Q100 automotive qualification.

Automotive-Grade Alternatives:

NCS20064DR2G (onsemi) and LMV324MX (National Semiconductor) include AEC-Q100 automotive qualification. NCS20064DR2G extends the operating temperature range to -40°C to 125°C and reduces supply current to 140 µA. LMV324Q1MAX/NOPB (Texas Instruments) provides automotive-qualified alternative with AEC-Q100 certification and Active product status.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. LMV324MX (National Semiconductor) is RoHS non-compliant and REACH Affected; this device should be avoided for applications requiring regulatory compliance. All other substitutes are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can MCP604-I/SL replace MCP604T-I/SL in production?

A: Yes. MCP604-I/SL is electrically and functionally identical to MCP604T-I/SL. The only difference is packaging format (Tube versus Cut Tape & Digi-Reel®). Selection depends on your assembly process requirements and tape-and-reel handling capabilities.

Q: What is the key difference between MCP604T-I/SL and AD8694ARZ?

A: The primary differences are slew rate (2.3 V/µs versus 5 V/µs), gain bandwidth product (2.8 MHz versus 10 MHz), and output current per channel (22 mA versus 80 mA). AD8694ARZ is suitable for higher-speed applications. Both maintain the same supply voltage range (2.7 V to 6 V) and are ROHS3 compliant.

Q: Can I use LMV324 series devices as a direct replacement?

A: LMV324 series devices are functionally compatible but with reduced performance. Slew rate is 1 V/µs (versus 2.3 V/µs) and gain bandwidth product is 1 MHz (versus 2.8 MHz). These devices are suitable only if your application does not require the higher performance of the MCP604T-I/SL. Verify that lower bandwidth and slower transient response are acceptable for your circuit.

Q: Is NCS20064DR2G suitable for my application?

A: NCS20064DR2G is compatible with MCP604T-I/SL in terms of package, pin count, and rail-to-rail output. However, it has lower slew rate (1.2 V/µs versus 2.3 V/µs) and lower gain bandwidth product (3 MHz versus 2.8 MHz). It includes AEC-Q100 automotive qualification and extends operating temperature to 125°C. Verify that reduced slew rate is acceptable for your design.

Q: What is the difference between AD8694ARZ and AD8694ARZ-REEL7?

A: Both devices are electrically identical. AD8694ARZ is supplied in Tube packaging, while AD8694ARZ-REEL7 is supplied in Cut Tape (CT) & Digi-Reel® packaging. AD8694ARZ-REEL7 has significantly higher inventory (36,253 units versus 12,900 units). Selection depends on your assembly process and tape-and-reel handling requirements.

Q: Why is LMV324ID marked as Last Time Buy?

A: LMV324ID has been designated Last Time Buy status by Texas Instruments, indicating that production will be discontinued. This device should not be selected for new designs. Use LMV324M/NOPB, LMV324MX/NOPB, or LMV324Q1MAX/NOPB instead.

Q: Can I use LMV324MX in a new design?

A: LMV324MX is not recommended for new designs. This device is RoHS non-compliant and REACH Affected, which may violate regulatory requirements for many applications. Use LMV324MX/NOPB (ROHS3 compliant) or LMV324Q1MAX/NOPB (automotive-qualified) instead.

Q: What is the operating temperature range difference?

A: MCP604T-I/SL operates from -40°C to 85°C. Most substitute devices extend this to -40°C to 125°C, providing wider temperature range. LMV324IDR operates from -25°C to 85°C, which is narrower than the original. Verify that the operating temperature range of your selected substitute meets your application requirements.

Q: Are all substitutes ROHS3 compliant?

A: No. LMV324MX (National Semiconductor) is RoHS non-compliant. All other recommended substitutes are ROHS3 compliant. Verify compliance requirements for your application before selecting a substitute.

Q: What is the supply current difference between MCP604T-I/SL and substitutes?

A: MCP604T-I/SL draws 230 µA (per 2 channels). NCS20064DR2G draws 140 µA, offering lower power consumption. AD8694ARZ draws 950 µA, consuming significantly more power. LMV324 series devices draw 410 µA. Select based on your power budget requirements.

Q: Can I mix different substitute parts in the same design?

A: All substitute devices maintain the same 14-SOIC package and pinout, so they are mechanically interchangeable. However, electrical performance differences (slew rate, bandwidth, output current) may affect circuit behavior. Use the same part number throughout a design unless performance differences are explicitly verified and acceptable.
