MCP601T-E/OT features higher slew rate (2.3 V/µs versus 1.5 V/µs), lower supply current (230 µA versus 600 µA), and extended operating temperature range (-40°C to 125°C versus 0°C to 70°C). Input offset voltage is higher (700 µV versus 250 µV). Output current per channel is lower (22 mA versus 35 mA). All parts are housed in SOT-23-5 packages.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this document are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level rating. All parts are suitable for standard surface mount assembly and storage processes.

Q: What is the difference between MCP6L1RT-E/OT and MCP6L1T-E/OT?

A: Both parts share identical electrical specifications and operating parameters. The primary difference is packaging format: MCP6L1RT-E/OT is supplied in Tape & Reel (TR) format, while MCP6L1T-E/OT is supplied in Cut Tape (CT) & Digi-Reel® format. Electrical performance and SOT-23-5 package configuration are identical.

Q: Can MAX4250EUK+T be used in applications requiring the full 0°C to 70°C operating temperature range?
