• Slew Rate: 0.003 V/µs
• Gain Bandwidth Product: 100 kHz
• Current - Input Bias: 1 pA
• Voltage - Input Offset: 3 mV
• Current - Supply: 600 nA
• Current - Output / Channel: 20 mA
• Voltage - Supply Span: 1.4 V to 6 V
• Operating Temperature Range: -40°C to 85°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 8-MSOP

Compliance & Status (Must Match Exactly):

Engineering Selection Recommendations

MCP6141T-I/MS is a direct substitute for MCP6141-I/MS based on the following engineering criteria:

1. Electrical Equivalence: All electrical parameters, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and supply voltage range, are identical.

2. Mechanical Compatibility: Both parts use the 8-MSOP surface mount package with identical pin configuration and physical dimensions (0.118", 3.00mm Width), ensuring direct PCB footprint compatibility.

3. Compliance Status: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited), meeting the same regulatory and environmental requirements.

4. Product Status: Both parts are in active production status from Microchip Technology, ensuring long-term availability and supply chain stability.

5. Packaging Variation: The only difference is the distribution format—MCP6141-I/MS is supplied in tube packaging, while MCP6141T-I/MS is supplied in cut tape format. This variation does not affect electrical performance or mechanical compatibility and is determined by procurement and assembly process requirements.

Frequently Asked Questions (FAQ)
