MCP635T-E/MF CMOS Amplifier Equivalent & Substitute Parts

Part Overview

The MCP635T-E/MF is a dual-channel CMOS operational amplifier manufactured by Microchip Technology, designed for rail-to-rail signal conditioning applications. This device integrates two independent amplifier circuits in a compact 10-DFN (3x3) surface mount package with exposed pad. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when packaging format differs while maintaining identical electrical performance specifications and functional characteristics. The primary variant listed differs only in tape and reel versus tube packaging configuration.

Substitute Part Grouping Explanation

Substitution eligibility for the MCP635T-E/MF is determined by strict equivalence across all electrical and mechanical parameters. The substitute relationship is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Amplifier Type: CMOS
• Number of Circuits: 2
• Output Type: Rail-to-Rail
• Slew Rate: 10 V/µs
• Gain Bandwidth Product: 24 MHz
• Current - Input Bias: 4 pA
• Voltage - Input Offset: 1.8 mV
• Current - Supply: 2.5 mA per channel
• Current - Output / Channel: 85 mA
• Voltage - Supply Span: 2.5 V to 5.5 V
• Operating Temperature: -40°C to 125°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 10-VFDFN Exposed Pad
• Supplier Device Package: 10-DFN (3x3)
• Mounting Type: Surface Mount

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The only permitted variation is in the distribution packaging format (Tape & Reel versus Tube), which does not affect component functionality or board-level integration.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP635T-E/MF and MCP635-E/MF are functionally equivalent dual-channel CMOS amplifiers suitable for identical circuit applications. Selection between these parts is determined solely by procurement and assembly requirements:

MCP635T-E/MF (Tape & Reel): Recommended for high-volume automated pick-and-place assembly operations where continuous reel feeding is standard practice.

MCP635-E/MF (Tube): Recommended for lower-volume production, manual assembly, or applications where tube packaging is preferred for component handling and storage.

Both variants maintain active product status with full RoHS3 compliance and REACH unaffected designation. Moisture sensitivity level 1 (unlimited) indicates no special storage or handling precautions are required. The 10-DFN (3x3) package with exposed pad is identical across both variants, ensuring identical PCB footprint, thermal performance, and board-level integration.

Frequently Asked Questions (FAQ)

Q: Can MCP635-E/MF be used as a direct replacement for MCP635T-E/MF on a circuit board?

A: Yes. Both parts are electrically and mechanically identical. The only difference is distribution packaging format (Tube versus Tape & Reel). Once soldered to the PCB, both components perform identically.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous plastic tape wound on a reel, suitable for automated assembly equipment. Tube packaging supplies components in a plastic tube, typically used for manual assembly or lower-volume production. The actual component and its specifications are identical.

Q: Are there any electrical performance differences between these two part numbers?

A: No. Both MCP635T-E/MF and MCP635-E/MF have identical electrical specifications including slew rate (10 V/µs), gain bandwidth product (24 MHz), input bias current (4 pA), and all other parameters listed in this document.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry moisture sensitivity level 1 (unlimited). No additional handling precautions are required for either variant.

Q: What is the 10-DFN (3x3) package?

A: 10-DFN refers to a 10-pin Dual Flat No-Lead package with 3mm × 3mm body dimensions. The exposed pad provides enhanced thermal dissipation. Both part variants use this identical package configuration.

Q: Can I substitute MCP635-E/MF for MCP635T-E/MF in my existing design?

A: Yes, provided your assembly process can accommodate tube packaging instead of tape and reel. The electrical and mechanical specifications are identical, and the PCB footprint is the same.

Q: What is the operating temperature range for both parts?

A: Both parts operate from -40°C to 125°C (TA). This range is identical for MCP635T-E/MF and MCP635-E/MF.

Q: Are there any other MCP635 variants available?

A: Based on the provided data, only MCP635T-E/MF and MCP635-E/MF are listed as equivalent substitutes. Both share the base product number MCP635 and are manufactured by Microchip Technology.
