MCP1631HVT-330E/SS Equivalent & Substitute Parts

Part Overview

The MCP1631HVT-330E/SS is a SEPIC (Single-Ended Primary-Inductor Converter) regulator controller IC manufactured by Microchip Technology. This device functions as a positive output step-up/step-down DC-DC controller, delivering transistor driver output for power management applications. The part operates across a supply voltage range of 4.6V to 16V and is housed in a 20-SSOP surface mount package. The MCP1631HVT-330E/SS is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when packaging format differs while maintaining identical electrical specifications and functional characteristics.

Substitute Part Grouping Explanation

The MCP1631HVT-330E/SS and its substitute part MCP1631HV-330E/SS share identical electrical and functional specifications. Both devices are manufactured by Microchip Technology and implement the same SEPIC controller architecture with matching supply voltage range (4.6V ~ 16V), control features (Enable, Frequency Control, Ramp), and operating temperature range (-40°C ~ 125°C). The devices are housed in the same 20-SSOP package with identical pin configuration and mechanical dimensions (0.209", 5.30mm Width).

The substitution is valid based on the following key parameters:

• Identical base product number (MCP1631)
• Matching topology (SEPIC)
• Identical output type and configuration (Transistor Driver, Positive)
• Same supply voltage specifications (4.6V ~ 16V)
• Identical control features and operating temperature range
• Same package type and pin count (20-SSOP)
• Equivalent compliance certifications (RoHS3, REACH Unaffected)

The only difference between these parts is the packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Tube format. Both formats contain the same die and are suitable for identical circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP1631HVT-330E/SS and MCP1631HV-330E/SS are active products with full RoHS3 compliance and REACH unaffected status, making them suitable for applications requiring environmental compliance. The selection between these parts should be based on procurement and assembly requirements rather than electrical performance, as they are functionally equivalent.

The MCP1631HVT-330E/SS in Tape & Reel format is optimized for high-volume automated assembly operations. The MCP1631HV-330E/SS in Tube format is suitable for lower-volume applications, manual assembly, or situations where tape-and-reel packaging is not required. Both parts maintain identical electrical characteristics, pin configuration, and thermal performance across the specified operating temperature range of -40°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Are MCP1631HVT-330E/SS and MCP1631HV-330E/SS electrically interchangeable?

A: Yes. Both parts implement identical SEPIC controller architecture with matching supply voltage range (4.6V ~ 16V), control features, and operating temperature specifications. They are pin-for-pin compatible and functionally equivalent.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Tube packaging supplies components in plastic tubes, typically used for lower-volume applications or manual assembly. The die and electrical performance are identical.

Q: Can I use MCP1631HV-330E/SS as a direct replacement for MCP1631HVT-330E/SS in my design?

A: Yes, provided your assembly process can accommodate Tube packaging. The electrical specifications, pin configuration, and thermal characteristics are identical. Verify that your manufacturing equipment can handle the alternative packaging format.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MCP1631HVT-330E/SS and MCP1631HV-330E/SS are RoHS3 compliant with REACH unaffected status.

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

A: Both parts operate across -40°C to 125°C junction temperature (TJ), suitable for industrial and extended temperature applications.

Q: Do these parts require different PCB layouts or design considerations?

A: No. Both parts use the same 20-SSOP package with identical pin configuration and mechanical dimensions (0.209", 5.30mm Width). PCB layout and design considerations remain unchanged.
