MCP1631VHV-330E/SS Equivalent & Substitute Parts

Part Overview

The MCP1631VHV-330E/SS is a Sepic Regulator Positive Output Step-Up/Step-Down DC-DC Controller IC manufactured by Microchip Technology. This power management IC operates as a transistor driver with a single positive output phase, designed for applications requiring flexible voltage conversion between step-up and step-down topologies. The device is currently in active production status with 777 units in stock. Substitute parts are identified when design requirements necessitate alternative inventory availability, different output voltage ratings, or equivalent functional performance within the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP1631VHV-330E/SS are identified based on strict parametric equivalence within the MCP1631 product family. All substitute parts maintain identical specifications across the following critical parameters:

• Topology: Sepic
• Function: Step-Up/Step-Down DC-DC control
• Output Type: Transistor Driver
• Output Configuration: Positive
• Number of Outputs: 1
• Output Phases: 1
• Supply Voltage Range: 4.6V ~ 16V
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Package / Case: 20-SSOP (0.209", 5.30mm Width)
• Mounting Type: Surface Mount
• Control Features: Enable, Frequency Control, Ramp
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitution is valid when the application requirements align with these parameters. Differences in part numbering reflect internal Microchip Technology designations and inventory classifications but do not affect functional equivalence for the specified electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

All four parts—MCP1631VHV-330E/SS, MCP1631HV-330E/SS, MCP1631HV-500E/SS, and MCP1631VHV-500E/SS—are active production components from Microchip Technology with identical functional specifications for Sepic topology DC-DC control applications. Selection between these parts is determined by inventory availability and internal part designation requirements rather than electrical or mechanical performance differences.

All parts maintain ROHS3 compliance and carry unlimited moisture sensitivity classification (MSL 1), ensuring compatibility with standard manufacturing and storage environments. The 20-SSOP surface mount package is consistent across all variants, supporting direct substitution in existing PCB designs without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can MCP1631HV-330E/SS replace MCP1631VHV-330E/SS in production designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The difference in part numbering reflects internal Microchip Technology designations and does not affect functional performance in Sepic topology applications.

Q: Are the MCP1631HV-500E/SS and MCP1631VHV-500E/SS interchangeable with the main part?

A: Yes. All four parts maintain identical specifications for supply voltage range (4.6V ~ 16V), operating temperature (-40°C ~ 125°C), package type (20-SSOP), and control features. Substitution is valid for applications within these parameter ranges.

Q: What is the significance of the "HV" and "VHV" designations in the part numbers?

A: These designations are internal Microchip Technology classifications. They do not represent differences in electrical performance, voltage ratings, or functional capability for the specified parameter set.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All parts use the identical 20-SSOP (0.209", 5.30mm Width) surface mount package, enabling direct substitution without PCB redesign or rework.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, meeting standard environmental and regulatory requirements.

Q: Which part should be selected based on availability?

A: Selection should be based on current inventory levels and supply chain requirements. MCP1631HV-330E/SS offers the highest inventory (2680 units), followed by MCP1631HV-500E/SS (2320 units), MCP1631VHV-500E/SS (1049 units), and MCP1631VHV-330E/SS (777 units).
