Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP601T-E/ST are identified based on functional equivalence within the general-purpose amplifier category. The substitution logic is determined by the following key parameters:

Primary Matching Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Mounting Type: Surface Mount
• Supply Voltage Range Compatibility: Minimum 2.7 V, Maximum 6 V or higher
• Operating Temperature Range: -40°C minimum and 125°C maximum or higher

Secondary Compatibility Factors:

• Slew Rate: 2.3 V/µs or greater
• Gain Bandwidth Product: 2.8 MHz or greater
• Current - Input Bias: 1 pA or lower
• Voltage - Input Offset: 700 µV or lower
• Current - Supply: 230 µA or lower
• Current - Output / Channel: 22 mA or greater
• Package compatibility: 8-TSSOP or equivalent footprint

Substitute parts must maintain functional equivalence in single-circuit rail-to-rail operation and surface mount configuration. Parts are grouped as direct equivalents when all primary criteria are met with identical or superior secondary performance characteristics.

Engineering Selection Recommendations

MCP601-E/ST (Microchip Technology)

The MCP601-E/ST is a direct equivalent to the MCP601T-E/ST. Both devices share identical electrical specifications, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current. The primary difference is packaging format: MCP601-E/ST is supplied in Tube packaging, while MCP601T-E/ST is supplied in Cut Tape (CT) & Digi-Reel® format. Both are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Selection between these two part numbers is determined by packaging and supply chain requirements rather than functional performance.

OPA337EA/250 (Texas Instruments)

The OPA337EA/250 is a manufacturer-recommended substitute for the MCP601T-E/ST. This device maintains functional equivalence as a general-purpose, single-circuit, rail-to-rail operational amplifier in surface mount configuration. The OPA337EA/250 demonstrates superior performance in specific parameters: lower input bias current (0.2 pA versus 1 pA), lower input offset voltage (500 µV versus 700 µV), and higher gain bandwidth product (3 MHz versus 2.8 MHz). However, the OPA337EA/250 exhibits lower slew rate (1.2 V/µs versus 2.3 V/µs), higher supply current (525 µA versus 230 µA), and reduced output current per channel (9 mA versus 22 mA). The maximum supply voltage is 5.5 V (versus 6 V), and the maximum operating temperature is 85°C (versus 125°C). The OPA337EA/250 is supplied in 8-VSSOP package format and carries MSL 2 (1 Year) moisture sensitivity rating. This substitute is suitable for applications where lower input offset voltage and input bias current are prioritized, provided that the reduced slew rate, lower maximum operating temperature, and reduced output current do not conflict with circuit requirements. Both devices are ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can MCP601-E/ST be used as a direct replacement for MCP601T-E/ST?

A: Yes. The MCP601-E/ST and MCP601T-E/ST are electrically identical. The difference is packaging format: MCP601-E/ST uses Tube packaging while MCP601T-E/ST uses Cut Tape (CT) & Digi-Reel® format. Selection depends on supply chain and assembly process requirements.

Q: Is the OPA337EA/250 a pin-compatible substitute for the MCP601T-E/ST?

A: Both devices use 8-pin surface mount packages (8-TSSOP and 8-VSSOP respectively). While pin counts are identical, physical package dimensions differ. The 8-VSSOP package (0.118", 3.00mm width) is narrower than the 8-TSSOP package (0.173", 4.40mm width). PCB layout and footprint verification is required before substitution.

Q: What are the key performance trade-offs when using OPA337EA/250 instead of MCP601T-E/ST?

A: The OPA337EA/250 offers lower input offset voltage (500 µV versus 700 µV) and lower input bias current (0.2 pA versus 1 pA). However, it has lower slew rate (1.2 V/µs versus 2.3 V/µs), higher supply current consumption (525 µA versus 230 µA), and reduced output current capability (9 mA versus 22 mA). The maximum operating temperature is limited to 85°C versus 125°C for the MCP601T-E/ST.

Q: Are all three parts ROHS3 compliant?

A: Yes. The MCP601T-E/ST, MCP601-E/ST, and OPA337EA/250 are all ROHS3 compliant and REACH unaffected.

Q: What is the difference in moisture sensitivity between these parts?

A: The MCP601T-E/ST and MCP601-E/ST have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. The OPA337EA/250 has MSL 2 (1 Year) rating, requiring storage in controlled humidity conditions and limiting shelf life to one year from manufacturing date.

Q: Can the OPA337EA/250 operate at the full 6 V supply voltage of the MCP601T-E/ST?

A: No. The OPA337EA/250 maximum supply voltage is 5.5 V, compared to 6 V for the MCP601T-E/ST. Applications requiring 6 V operation must use the MCP601T-E/ST or MCP601-E/ST.

Q: Which substitute is better for high-temperature applications?

A: The MCP601T-E/ST and MCP601-E/ST support operating temperatures up to 125°C. The OPA337EA/250 is limited to 85°C maximum operating temperature. For applications requiring operation above 85°C, the MCP601T-E/ST or MCP601-E/ST must be used.

Q: Are there output current limitations when substituting with OPA337EA/250?

A: Yes. The OPA337EA/250 provides 9 mA maximum output current per channel, while the MCP601T-E/ST provides 22 mA. Applications requiring output currents above 9 mA must use the MCP601T-E/ST or MCP601-E/ST.
